Description

INHIBITORS OF PROTEIN QUINABA FOR THE TREATMENT OF NEUROLOGICAL DISORDERS BACKGROUND OF THE INVENTION Protein kinases are a broad class of enzymes that act to chemically modify many cellular proteins, by phosphorylating amino acids. Inhibitors of protein kinases are li? structurally varied, and have variable (and sometimes contradictory) effects on the nervous system and other tissues. A given protein kinase inhibitor can influence more than one protein kinase. For example, it was originally reported that K-252a, a material in the form of an alkaloid isolated from the culture broth of Nocardiopsis sp. and Actino adula sp. , is a protein kinase C inhibitor, but was subsequently found to also inhibit protein kinases A and G, myosin light chain kinase, and trk (a tyrosine kinase 0 activated by growth factor). nervous (NGF), the latter being a neurotrophic protein that promotes the survival of peripheral, sensory, and sympathetic neurons). Consistent with this latter effect, K-252a 5 blocks the neurotrophic actions of nerve growth factor on PC-12 cells (chromaffin cells of rat adrenal medullary tumors, feocro ocitomas), and promotes the survival of ganglionary neurons of dorsal root and hippocampal neurons. However, it has been found to be cytotoxic in a wide range of concentrations, leading some researchers to conclude that it has limited utility in vivo. A microbial alkaloid related to K-252a, staurosporine, also has a variety of effects on different protein kinases and cell types. It was discovered that staurosporine has effects in the form of nerve growth factor on PC-12 cells, and protects the gerbil hippocampus from post-ischemic injury. It can reverse the damage to cholinergic neurons in the rat basal forebrain. K-252a and staurosporine have been proposed as tumor inhibitors. Staurosporine has been offered as an insecticide. Staurosporine derivatives have been made with a hydrocarbyl radical or an acyl radical substituted on the methylamine nitrogen, and have been proposed for the following uses: tumor inhibition, inhibition of inflammation, immunomodulation, and treatment of diseases of the cardiovascular and central nervous systems.

A particularly important effect of nerve growth factor on these cells is a rapid stimulation of ornithine decarboxylase (ODC) activity, an effect reported to be blocked by 200 nM K-252a (Koizumi et al. 1988). In the experiments of this example, PC-12 cells (obtained from Dr. G. Guroff, National Institute of Health, Bethesda, MD) were cultured in 48-well dishes, at a density of 6 × 10 4 cells / square centimeter, and incubated with a drug vehicle (0.5 percent dimethyl sulfoxide), K-252a, -.- staurosporine, or HBCS. K-252a and staurosporine are commercially available from Kamiya Biomedical. Four hours after the addition of the drug, the cells were harvested for the ornithine decarboxylase assay, as described by Huff et al. (J. Cell Biol. 88: 189-198, 1981). All three compounds produced an induction (ie, an increase) in ornithine decarboxylase activity, but there were considerable differences in potency and efficacy (Figure 1). K-252a produced a dose-dependent induction of ornithine decarboxylase activity, with detectable effects at 2 nM, and increasing to a maximum at 200 nM (36.3-fold induction). In the same way, the effects of staurosporine were detectable at 2 nM, but reached their peak at 20 nM (induction 34.7 times), and declined considerably at 200 nM. HBCS (Example 1) induced similarly at 2 nM, but higher concentrations failed to give a greater effect, such that the maximum efficacy was much lower than that of the other two compounds (6.5-fold induction). In another experiment, the effects of PTCS, PCS, and ECS (Example 2) on the activity of ornithine decarboxylase of PC-12 cells were compared with those of K-252a. At concentrations of 200 nM, which express the activity of K-252a as 100 percent, the PTCS exhibited 71.4 percent of the activity of K-252a, while the PCS and the ECS exhibited 88.9 percent and 61.9 percent. percent of the activity of K-252a, respectively. However, the protein kinase C H-7 inhibitor did not induce ornithine decarboxylase activity at 30 μM, a concentration known to inhibit the activity of protein kinase C (Nakadate et al., Biochem, Pharmacol. : 1541-1545, 1988). The ability of K-252a, staurosporine, and HBCS to enhance and / or inhibit the bioactivity of nerve growth factor was assessed by adding 10 nanograms of nerve growth factor per milliliter of cell culture medium, in the absence or in the presence of the above compounds at the concentrations indicated above, followed by an ornithine decarboxylase assay of the cells as described above (Figure 2). This concentration of nerve growth factor was selected to provide an intermediate level of induction, such that the effects of potentiation or inhibition of the compounds could be detected. K-252a in 200 nM inhibited the induction of the nerve growth factor of ornithine decarboxylase, -r- as reported by Koizumi et al. (1988), but, in a surprising way, potentiated induction at lower concentrations (2 nM and 20 nM). Staurosporine, at 2 nM, also potentiated induction by nerve growth factor, but 5 this effect was lost at higher concentrations (20 and 200 nM). The HBCS, in contrast, potentiated the effects of nerve growth factor in all concentrations tested. This surprising effect is shown in relation to the modest ornithine decarboxylase inducing effects of HBCS alone 0 in Figure 3.
Example 6 The effect of K-252a on the activity of choline acetyltransferase (ChAT) in dissociated spinal cord cultures prepared from fetal rats was tested by conventional methods (see below). Choline acetyltransferase is an enzyme that catalyzes the synthesis of the neurotransmitter acetylcholine, and is a specific biochemical marker for cholinergic neurons. In the spinal cord, the vast majority of cholinergic neurons are motor neurons. The assay of this enzyme, therefore, can be used as an indication of the effects of a factor (or factors) on the survival of cholinergic neurons and / or the regulation of this enzyme. K-252a was added at the indicated concentrations to the cultures, after being incubated for 2 to 3 hours, after coating to allow the cells to bind to the substrate. The activity of choline acetyltransferase was measured after 48 hours of culture. K-252a in spinal cord cultures, resulted in a dose-dependent increase in choline acetyltransferase activity, with maximum efficacy (2 to 3 fold increase) reached at 200-300 nM (Figure 4) . Higher concentrations resulted in a decrease in choline acetyltransferase activity (Figure 4). The longer incubation times of the culture, up to 7 days, resulted in 4 to 5 fold increases in choline acetyltransferase activity (Figure 5) due to the decreased baseline level of choline acetyltransferase activity. In this culture system, increasing numbers of motor neurons degenerate and die over time under basal conditions (control) (McMana an et al., Developmental Biol. 125: 311-320, 1988). The results shown in Figures 4 and 5 are the result of a single application of K-252a on the day of initiation of the culture, indicating a prolonged effect on the survival of cholinergic neurons of the spinal cord and / or the regulation of the enzyme itself. Experiments were performed with cultures dissociated from fetal rat spinal cord cells in general as described (Smith et al. J. Cell Biol. 101: 1608-1621, 1985). Dissociated cells were prepared from dissected spinal cords of 14-day old brionic rats by conventional techniques known to those skilled in the art, using tissue dissociation with trypsin (Smith et al., Supra). The cells were seeded (coated) in 6x105 cells / square centimeter in plastic tissue culture wells coated with poly-1-ornithine in a serum free N2 medium, and incubated at 37 ° C in a humidified atmosphere of the 5 percent C02 / 95 percent air (Bottenstein et al., Proc. Nati, Acad. Sci. USA 76: 514-517, 1979) for 48 hours. Choline acetyltransferase activity was measured using modifications of the Fonnum method (J Neurochem 2?: 407-409, 1975) according to Ishida and Deguchi (J. Neurosci., 3: 1818-1823, 1983), and McManaman and collaborators, supra (1988). The activity was normalized to the total protein measured by the bicinconic acid / Cu ++ reaction (BCA protein assay reagent, Pierce, Rockland, IL).
Example 7 More than 100 functional derivatives of K-252a were tested in the spinal cord choline acetyltransferase assay, to determine its relative effectiveness. The data in Figure 8 show that, of the original functional derivatives tested at 300 and 30 nM, 28 resulted in choline acetyltransferase activity significantly increased by 300 nM. A functional derivative, compound 11-21, was also active at 30 nM (30 percent improvement in choline acetyltransferase activity above baseline levels). This compound was more potent than K-252a or the remaining analogs, since none of these actively enhanced choline acetyltransferase activity by 30 nM. Figure 13 shows the ability of the original 28 K-252a derivatives shown to significantly increase the choline acetyltransferase activity in rat spinal cord cultures, as well as 30 additional derivatives (Compounds 11-29 to 11-34) , 11-36 to 11-56, and IV-1 to IV-3, including all). Figure 13B shows the ability of the derivatives of K-252a 11-66-80, IV-5, IV-6, VI-1, and VI-2 to significantly increase the activity of choline acetyltransferase in cultures of Rat spinal cord. Figure 13C shows the ability of the 12 additional K-252a derivatives to significantly increase choline acetyltransferase activity in rat spinal cord cultures.
Example 8 K-252a, as well as more than 50 functional derivatives, were evaluated for their ability to promote the survival of dorsal root ganglionic neuronal cells. Cell survival was measured by recovery of calcein AM, a viable dye analogue, fluorescein diacetate. Calcein is recovered by viable cells and dissociates intracellularly in fluorescent salts that are retained by the intact membranes of viable cells. The microscopic counts of the viable neurons correlate directly with the relative fluorescence values obtained with the fluorimetric viability assay. Accordingly, this method provides a reliable and quantitative measurement of cell survival in the total cell population of a given culture (Bozyczko-Coyne et al., J Neur., Meth 50,205-216, 1993). The dorsal root ganglia of 8-day-old chicken embryos were dissected, and dissociated cells were prepared by the subsequent dissociation of Dispase (neutral protease, Collaborative Research). The neurons were seeded in a low density (1.8xl04 cells / square centimeter) in 96-well plates coated with poly-L-ornithine and laminin. The cells were cultured for 48 hours in serum-free N2 medium (Bottenstein and Sato, 1979) at 37 ° C in a humidified atmosphere, with 5 percent C02 / 95 percent air. Cell survival was evaluated at 48 hours using the viable fluorometric assay described above. The survival of the dorsal root ganglionic neurons was improved by K-252a in a concentration-dependent manner. The maximum activity was observed at approximately 100 nM (Figure 6). 24 of the 50 analogues tested were active to promote the survival of dorsal root ganglion neurons, 22 of which are shown in the Figure 7. All of these analogues were also active to increase choline acetyltransferase activity of the spinal cord (see Example 5, Figure 8). The original 22, as well as the 2 additional active analogues (11-30, 11-32) are shown in Figure 14. Microscopic examination of dorsal root ganglion neurons stimulated with the 24 active functional derivatives indicated better growth of nerve fibers too.
Example 9 Infusion of the amino acid excitation cainic acid (cainate) directly in the ventricles of a rodent brain, results in neuronal degeneration of pyramidal cells of the hippocampus. This neuronal death is characterized by a marked increase in the proteolysis of the cytoskeletal protein, spectrin. The spectrin decomposes the products that can be measured in the hippocampal homogenates within 24 hours following the administration of the kainate. The magnitude of spectrin proteolysis is highly correlated with the magnitude of neuronal death in hippocampal pyramidal cells (Siman et al., J Neurosci, 9: 1579-1590, 1989), and therefore, spectrin proteolysis is an excellent biochemical marker of neuronal degeneration induced by arousal amino acids. Excessive release of endogenous arousal amino acids has been implicated as an etiology in numerous diseases and neurological disorders, including concussion and other ischemic lesions; Alzheimer's disease, motor neuron disease, including amyotrophic lateral sclerosis; Parkinson's disease; Huntington's disease; dementia due to AIDS; epilepsy; and concussive or penetrating lesions of the brain or spinal cord. The results shown in Figures 9 to 12 were generated according to the following methods: Cainate Infusion Regime: The effect of K-252a or its derivatives on neurite damage induced by kainate was evaluated. Male Sprague-Dawley rats or adult females (175-250 grams) were anesthetized with Nembutal (50 milligrams / kilogram, intraperitoneally). Each rat was given a test compound (in a total of 5 microliters) before and after treatment with kainate (5 microliters) by intracerebroventricular infusion. This was done using a dose and infusion schedule as indicated for the previous individual cases. The control animals received a vehicle instead of the cainate and the infusion of the drug. For the anatomical studies, intracerebroventricular infusions were applied through a cannula (Plástic One, Roanoke, VA) implanted approximately 1 week before the infusions of the drug, and placed in the stereotactic coordinates: anterior-posterior in bregma, 1.5 mm lateral to bregma, and 4.4 mm ventral from the top of the skull. The results of this treatment regimen were evaluated two weeks later, using the anatomical analysis described below. In studies to evaluate the effect of K-252a or its derivatives on the kaolin-induced spectrin proteolysis, the anesthetized rats received a 5 microliter intracerebroventricular infusion of the drug or the vehicle, simultaneously with kainate, through a Hamilton syringe. 10 microliters placed in the stereotactic coordinates described above. These rats were sacrificed 24 hours later, and subjected to biochemical analysis as described below. Anatomical and Biochemical Analysis: The anatomical analysis was performed as follows. The rats were sacrificed by decapitation two weeks following the treatments, and the brains were quickly removed and frozen on dry ice. A series of coronal sections mounted on slides of each brain were stained with thionin and examined microscopically. Damage to the hippocampus was quantified by adding the total number of four anatomically defined regions of the hippocampus (CA1-4 according to the classification of Lorente and Novas described by Shepard, 1979, The Synaptic Organization of 0 the Brain, Oxford, page 310, incorporated herein by reference), both on the left and right sides of the brain, which suffered a loss of pyramidal cells. The biochemical analysis was performed as follows: Calpain I-sensitive proteolysis of brain 5 spectrin (fodrin) in hippocampal homogenates was evaluated using an immunoblot analysis described by Siman et al. (1988, Neuron, I: 279-287, incorporated in the present as a reference). Briefly stated, the rats were sacrificed by decapitation 24 hours following treatment, and the dorsal 0 hippocampus was rapidly dissected from the brain, and homogenized in 20 mM Tris-HCl (pH 7.4) containing 0.1 mM phenylmethylsulfonyl fluoride. . Proteins from the aliquots of each homogenate were separated by SDS-PAGE, and an immunoblot analysis was used to quantify the amount of decay spectrin induced by kainate in each sample. Figure 9 shows the effect of K-252a on neuronal degeneration induced by kainate in the hippocampus. Male and female cannulated Sprage-Dawley rats received 0.4 micrograms of K-252a, or of a vehicle, 30 minutes before, and at approximately 3 and 24 hours following the injection of kainate (0.6 micrograms) directly into the lateral cerebral ventricles of the brain (icv). Two weeks later the brains were separated, frozen, sectioned, and stained for histological analysis, as described below. The data shown is the average number of sub-regions of the hippocampus damaged for each group, + Standard Error of the Average (S.E.M.). The K-252a significantly reduced the number of damaged areas within the hippocampus from 3.86 + 0.78 (in the absence of K-252a) to 1.18 ± 0.4 in the presence of K-252a). Figure 10 shows the effect of K-252a on the decay of specimen induced by kainate in the hippocampus. Female Sprague-Dawley rats received 0.4 micrograms of K-252a, or of a vehicle, along with a neurotoxic dose of kainate (0.6 micrograms), by intracerebroventricular infusion. The simulated control animals received vehicle infusions, but not kainate or K-252a. Twenty-four hours later, dorsal hippocampal homogenates were analyzed by spectrin decomposition products as described below. The magnitude of the spectrin proteolysis is expressed as a percentage increase in the spectrin decomposition products for each group on the simulated control values. The data shown is the increase in the average percentage in the products of decomposition of spectrin for each group (simulated = 100 percent + Standard Error of the Average.) The infusion intracerebroventricular of K-252a significantly reduced the degree of proteolysis of spectrin , from about 140 ± 15 percent (in the absence of K-252a) to about 102 + 10 percent (in the presence of K-252a) of the simulated values Figure 11 shows the effect of HBCS on induced neuronal degeneration In the hippocampus, the female Sprague-Dawley rats received 0.8 micrograms of HBCS, or vehicle, 40 minutes before, and approximately 4 hours after the cinate (0.6 micrograms) by intracerebroventricular infusion. The brains were separated, frozen, sectioned, and stained for histological analysis, as described below. average number of sub-regions of the hippocampus damaged by each group, ± standard error of the average. The HBCS significantly reduced the number of damaged areas within the hippocampus from approximately 2.5 + 0.6 (without treatment with HBCS) to 1.3 ± 0.5 (with HBCS treatment).
Figure 12 compares the effect of three functional derivatives of K-252a on the decay of specimen induced by kainate in the hippocampus. Female Sprague-Dawley rats received 0.4 micrograms of K-252a, or compounds III-1 or 11-21, or vehicle, together with a neurotoxic dose of kainate (0.6 micrograms), by intracerebrovicular infusion. The simulated control animals received vehicle infusions, but nothing of kainate derivative K-252a. Tw-four hours later, homogenates of the dorsal hippocampus were analyzed by the spectrin decomposition products as described below. The magnitude of the spectrin proteolysis is expressed as a percge increase in the products of decomposition of spectrin by each group on the simulated control values. The data shown is the average percge increase in the products of decomposition of spectrin for each group (simulated = 100 perc + Standard Error of the Average. Intracerebrovicular infusion of K-252a reduced the degree of spectrin proteolysis, from approximately 128 + 9 perc(vehicle treatm to approximately 104 + 9 perc(in the presence of K-252a) from the simulated values. The derivatives of K-252a III-1 and 11-21 failed to prevthe proteolyysis of specimen induced by kainate.
Example 10 K-252a was tested for its ability to promote survival in striated cultures. Striae from 17-day rat embryos were dissected, and the cells dissociated by Dispase (neutral protease, Collaborative Research). Neurons were seeded at 5x104 cells / well (1.5 x 105 / cm2) in 96-well dishes, the cavities having been previously coated with poly-1-ornithine and laminin. Cells were cultured in serum-free N2 medium containing 0.05 percbovine serum albumin (Bottenstein and Sato, 1979) at 37 ° C in a humified atmosphere, 5 percC02 / 95 percair. Cell survival was tested 5 days after sowing, using the calcein viable cell fluorometric assay described in Example 8. The survival of striatal neurons was improved by K-252a in a concation-dependmanner. Maximum activity was found with 75 nM K-252a, which produced an efficacy of 3 to 4 times more than the control (Figure 15). In the control cultures, 90 percof the neurons coated on day zero died in 5 days, whereas the cultures treated with K-252a, 50 percof the neurons survived (Figure 16). The effect of survival in striated neurons occurred after 3 days in culture, and was sustained for at least 7 days in culture. These results are from a single application of K-252a on the day of initiation of the culture, and indicate that the effect on the survival of neurons is sustained. Figure 17 is a pair of photomicrographs taken from control cultures or cultures treated with K-252a at 75 nM. There was an increase in cell survival and an overgrowth of neurites in these cultures in the presence of K-252a at 75 nM.
Example 11 31 functional K-252a derivatives were tested for their potency and efficacy in the striated cell survival assay of Example 10. Figure 18 shows data on 18 K-252a derivatives that promoted the survival of striated neurons .
Example 12 Compounds of the invon were evaluated for their ability to promote survival and increase in choline acetyltransferase activity in basal forebrain cultures. The activity of choline acetyltransferase in these cultures is a biochemical marker for cholinergic neurons (less than 5 percof cells in culture), which represthe largest cholinergic input to the formation of the hippocampus, the olfactory nucleus, the interpeduncular nucleus, to the cortex, to the tonsils, and to parts of the thalamus. The representative compounds of the invention not only increased the activity of choline acetyltransferase, but in addition, increased the overall survival of the neurons in the basal forebrain cultures. The basal forebrain was dissected from either 17- or 18-day rat embryos, and the cells were dissociated with Dispasa ™ (neutral protease, Collaborative Research). Neurons were coated at 5 x 10 4 cells / well (1.5 x 10 5 cells / square centimeter) in the wells of 96-well dishes previously coated with poly-1-ornithine and laminin. Cells were cultured in serum free N2 medium containing 0.05 percent bovine serum albumin (BSA) (Bottenstein et al., Eupra) at 37 ° C in a humidified atmosphere of 5 percent C02 / 95 percent air . The activity of choline acetyltransferase was measured in vitro on the sixth day, using a modification of the Fonnum procedure (supra) according to McManaman et al (supra), and Glicksman et al. (J. Neuroschem 61: 210-221). , 1993). Cell survival was evaluated 5 days after coating, using the calcein AM fluorimetric assay described by Bozyczko-Coyne et al. (Supra). The culture medium was partially aspirated at the time of the assay to leave 50 microliters per cavity. Then an 8 μM AM calcein supply was added to 150 microliters of Dulbecco's phosphate buffered serum (DPBS); Jibco BRL), to give a final concentration of 6 μM, in 200 microliters per cavity, in a 96-well dish. Plates were incubated for 30 minutes at 37 ° C, followed by four serial dilutions with 200 microliters of DPBS. The relative fluorescence of each cavity was measured using a plate reading fluorometer (Cytoflur 2350, Millipore) at an excitation wavelength of 485 nanometers, an emission wavelength of 538 nanometers, and a sensitivity position of # 3 . The average fluorescence background calculated from 6 cavities that received calcein AM, but did not contain cells, was subtracted from all values. The linearity of the fluorescence signal was verified during the incubation time of the substrate of 30 minutes for the range of cell densities found in these experiments. The K-252a, as well as at least twelve derivatives of K-252a (II-3, II-5, 11-10, 11-20, 11-21, 11-22, 11-30, 11-32, 11- 51, 11-62, 11-63, 11-64, 11-65) promoted the survival of basal forebrain neurons (Figure 19).
EXAMPLE 13 The following tests were conducted to evaluate the effect of Compound 11-51 on cortical cholinergic function, when subjected to nucleus basalis rats. Cholinergic neurons that originate from the basal forebrain, and project to the hippocampus via the septo-hippocampal path, or to the cortex through the corticobasal path, suffer profound degeneration during the course and progress of the Alzheimer disease. There is some degree of correlation between the loss of these neurons, and decreases in cognitive and memory function in individuals afflicted with this disorder (Fibiger, II, Trends in Neurosci 14: 220-223, 1991). Several models of cholinergic dysfunction have been proposed that show the loss of biochemical markers, as well as behavioral deficits. These models are parallel to the progress of Alzheimer's disease (Olton, D. and collaborators "Dementia: animal models of the cognitive impairments produced by degeneration of the basal forebrain cholinergic system" in Meltzer, H., (Ed.) Psychopharmacology: The Third Generation of Progress, Raven Press, NY, 1987, pages 941-953, Smith, S. Brain Res. Rev. 13.103-118, 1988). For example, a model of cholinergic degeneration is the excitotoxic lesion of the nucleus basalis (Wenk, G. et al., Exp. Brain Res. 56: 335-340, 1984). Lesions in cholinergic neurons within the basal forebrain result in the loss of neuronal cell bodies in this region, and the subsequent loss of cholinergic terminal markers in the frontal and parietal cortex (Dunnett, S. et al., Trends Neurosci 14: 494-501, 1991). Using the following methods, Compound 11-51 was shown to increase cortical cholinergic function in rats that underwent lesions of the nucleus basalis. Male Sprague-Dawley rats (225 to 275 grams) were used for all experiments. Unilateral ibonic lesions of the nucleus basalis magnocelularis were produced by methods known to those skilled in the art (see, for example, Wenk et al., Supra), with the modifications described below. The rats were anesthetized with 50 milligrams / kilogram of pentobarbital, and 5 micrograms of ibotenic acid (in 1 microliter of PBS) was injected, unilaterally, into the nucleus basalis magnocelularis. The coordinates used were from the Paxinos and Watson brain atlas (posterior 1.5 millimeters, 2.8 millimeters lateral, 7.2 millimeters dorso-ventral). The injections took place over a period of 6 minutes. Dye injections indicated that the injections went directly to the nucleus basalis. Compound 11-51 was dissolved in Solutol ™ at 30 percent in concentrations of 0.01 to 0.3 milligrams / milliliter. The compound (or the Solutol ™ vehicle) was administered subcutaneously 1 day after, or 6 hours before, inducing lesions in the nucleus basalis, and every 48 hours thereafter. The doses were 0.01, 0.03, 0.10, and 0.30 milligrams / -kilogram. The experiments were completed 4 to 21 days after inducing the lesions. The activity of choline acetyltransferase was measured in tissue homogenates of the frontal-parietal cortex by the Fonnum method (supra). The activity of choline acetyltransferase in the frontal cortex, ipsilateral to the side of the lesion, was compared and normalized with the activity of choline acetyltransferase in the contralateral side (the side without injury). The activity of choline acetyltransferase is expressed as the ratio of ipsilateral to contralateral. Data were analyzed by ANOVA, and differences between treatments were determined by Tukey post-hoc test. In animals in which lesions were made in the nucleus basalis, there was a time-dependent decrease in cortical choline acetyltransferase activity, presenting the maximum loss between 3 and 7 days after the injury (Table 6). The route of administration, the doses, and the dosing schedule were based on preliminary data showing the effects of Compound 11-51 on choline acetyltransferase levels in the basal forebrain of adult rats. To evaluate the effects of Compound 11-51 on the levels of choline acetyltransferase (ie, on cholinergic function) in animals with lesions, the drug was administered 1 day after inducing the lesions for 14 to 21 days, or hours before surgery for 4 days.

The frontal cortex was assayed for the activity of choline acetyltransferase at the indicated time after the injury. Significantly different from the control without injury (p <0.05).
Dose response studies were conducted with compound 11-52, in doses of 0.01, 0.03, and 0.10 milligrams / kilogram (Table 7). Subcutaneous injections of compound 11-51 were given on alternating days for 21 days, starting 1 day after inducing lesions with ibotenic acid. The results showed that, with a dose as low as 0.03 milligrams / kilogram, compound 11-51 was effective in attenuating the disease in cortical choline acetyltransferase activity (Table 7).

The systemic administration of Compound 11-51 attenuated the decrease in cholinergic function in the frontal cortex measured at 4, 14, and 21 days after inducing the lesions (Table 8). In rats with unilateral lesions, the activity of choline acetyltransferase on the contralateral side remained unchanged, suggesting that Compound 11-51 only affected neurons with lesions.

An in ovo model can be used to assess the ability of a compound to influence the death of programmed motor neurons in development. In the chicken, the somatic motor neurons suffer a death that occurs naturally between embryonic days 6 and 10 (E6 and ElO) (Chu-Wang et al., J. "Comp.Neurol., 177: 33-58, 1978; Hamburger , J. Comp.Neurol., 160: 535-546, 1975; McManaman et al., Neuron 4: 891-898, 1990.) During this period, the number of motor neurons on both sides of the lumbar spinal cord of embryos of chicken in development, it is reduced from approximately 40,000 to 23,000. Chicken embryos (E6-E9) were treated with vehicle (Solutol ™ HS 15 at 5 percent, BASF Aktiengesellschaft), or the concentrations of Compound 11-51 described. The treatments (50 microliters) were applied to the vascularized chorioallantoic membrane through a window in the cover by the method of Oppenheim et al. (Science 240: 919-921, 1988). The embryos were sacrificed in the ElO, and the spinal cords were removed, fixed in Carnoy's solution (10 percent acetic acid, 60 percent ethanol, 30 percent chloroform), embedded in paraffin, sectioned in sections of 8 microns, and stained with thionin as described previously (Oppenheim et al., supra). The motor neurons (identified by morphology and position) were counted in each tenth section according to previously established criteria (Oppenheim et al., J .. Comp.Neurol. 210: 174-189, 1982; Oppenheim et al., "Comp.Neurol., 246: 281-286, 1986.) Daily application of Compound 11-51 to the chorioallantoic membrane of chickens E6 to E9 in ovo, resulted in a dose-dependent increase in the number of surviving lumbar motor neurons (Figure 20) At the lowest effective dose tested (1.17 micrograms / egg), there was a 16 percent improvement in motor neuron survival, maximum effect was achieved at a dose of 2.3 micrograms / egg, resulting in a 40 percent increase in the survival of the motor neurons of the treated embryos versus the control ones treated with vehicle In 7 micrograms / egg, there was no greater increase in the survival of the motor neurons, indicating that, in this situation, a maximum response of 2.3 micrograms / egg had been reached.
Example 15 Motor neurons in the hypoglossal nucleus innervate the tongue by means of the hypoglossal nerve. In adult rats, transection of the hypoglossal nerve results in a dramatic loss of choline acetyltransferase activity in the motor neurons of the hypoglossal nucleus, without affecting the number of cells. The loss of choline acetyltransferase activity serves as a model to invert an immature phenotype. The left hypoglossal nerve was cut under the digastric muscle of the neck of each adult female Sprague-Dawley rat (120 to 180 grams) under anesthesia with Nembutal. 50 microliters of compound 11-51 were applied in Solutol ™ 10 percent (HS 15, BASF Aktiengesellschaft) or vehicle only, to a piece of gel foam, and then the proximal end of the transected nerve was wrapped together with the foam gel, in a paraffin film. At the end of 7 days, the rats were perfused under deep anesthesia with 4 percent paraformaldehyde in Sorenson pH buffer (0.1 M NaP04, pH 7). The brainstem was removed, and it was immersed in fixative for 24 hours, then rinsed well, and placed in 30 percent sucrose for cryoprotection before being sectioned. Coronal sections of 40 micras were cut from the brain, and stored in Sorenson pH buffer at 4 ° C, until they were stained. The hypoglossal nucleus yielded 40 to 48 sections, and each fifth section was processed for immunohistochemistry using the anti-ChAT mouse monoclonal antibody, 1E6, as described previously (Chiu et al., J. Comp.Neurol., 328: 351 -363, 1993). The neurons immunoreactive to choline acetyltransferase were visualized in sections by avidin-biotin amplification, with the Vectastain Elite ABCMR kit (Vector Laboratories, Burlingame, CA). Each fifth section of the hypoglossal nucleus was processed, and the immunoreactive cells of the control (non-injured) were counted, and the axotomized sides of each animal were counted. The results are expressed as the percentage of neurons immunoreactive to choline acetyltransferase on the axotomized side in relation to the number of neurons immunoreactive to choline acetyltransferase on the non-injured side. The application of 100 micrograms of Compound II-51 to the cut end of the hypoglossal nerve resulted in a significant number of neurons immunoreactive to choline acetyltransferase (33.7 percent + 9.9 (average + Standard Error of the Average)) (Figure 21) . In contrast, there were very few neurons immunoreactive to choline acetyltransferase (8.07 percent + 2.9 (average + Standard Error of Average)) in control animals treated with vehicle.
