Definitions
- This invention pertains to compositions and methods for long-term contraception or sterilization of mammals.
- compositions that have sometimes been used for long-term contraception include those based upon natural or synthetic steroidal hormones to "trick" the female reproductive tract into a "false pregnancy.” These steroidal hormones must be administered repeatedly to prevent completion of the estrous cycle and conception. Steroids have side effects that can be potentially dangerous.
- Antibodies can be developed to specific hormone receptors (such as die LH receptor) and then coupled to a toxin. All cells with LH receptors should then be destroyed. Although various cell types have not been characterized in dog corpora lutea, destruction of any luteal cell type could potentially result in luteolysis if cell types communicate. " (citations omitted) P. Olson et al., "New Developments in Small Animal Population Control, " JAVMA, vol. 202, pp. 904-909 (1993) gives an overview of methods for preventing or terminating unwanted pregnancies in small animals.
- Tissue-specific cytotoxins- Permanent contraception in females and males might be achieved by administration of a cytotoxin that is linked to gonadotropin-releasing hormone (GnRH) and that selectively destroys gonadotropin-secreting pituitary cells.
- GnRH gonadotropin-releasing hormone
- a cytotoxin linked to antibodies against gonadotropin receptors could be targeted to alter gonadal function. Toxins would need to be carefully targeted to specific cells, yet be safe for all other body tissues.” (citation omitted).
- LH and hCG are homologous hormones that produce similar effects.
- GnRH gonadotropin-releasing hormone
- U.S. Patents No. 5,378,688; 5,488,036; and 5,492,893 disclose compounds said to be useful in inducing sterility in mammals.
- the disclosed compounds were generically described as GnRH (or a GnRH analog) conjugated to a toxin.
- the toxin was preferably linked to the sixth amino acid of the GnRH agonist.
- the toxin was preferably one with a translocation domain to facilitate uptake into a cell.
- conjugation of the GnRH agonist to the toxin is necessary because, for the most part, the above toxins, by themselves, are not capable of binding with cell membranes in general.
- the toxins specifically mentioned appear all to have been metabolic toxins, for example ricin, abrin, modeccin, various plant-derived ribosome-inhibiting proteins, pokeweed antiviral protein, ⁇ -amanitin, diphtiieria toxin, pseudomonas exotoxin, shiga toxin, melphalan, methotrexate, nitrogen mustard, doxorubicin, and daunomycin. None of these toxins is believed to be toxic due to direct interaction with the cell membrane. In die in vivo experiments reported, d e most effective time course was reported to be weekly injections for 4 weeks. (E.g., Pat. 5,488,036, col.
- the toxins must in general be internalized into the target cells to have effect, and do not act on cell membranes; in addition, at least some of these toxins must be secondarily transported from the membrane-bound vesicle into the cytoplasm to interact widi ribosomes, mitochondria, or other cellular components.
- amphipathic lytic peptides are ideally suited to use in a ligand/cytotoxin combination to specifically induce sterility or long-term contraception in mammals.
- the peptides act directly on cell membranes, and need not be internalized.
- GnRH agonist GnRH agonist
- a membrane-active lytic peptide produces long-term contraception or sterilization in mammals in vivo.
- sterility results even when the combination is administered to a sexually immature animal: The combination then prevents sexual maturation.
- the compounds used in die present invention are relatively small, and will not be antigenic. (Lytic peptides are known not to be very antigenic; and the ligands are not antigenic at all.)
- the compounds may be administered in a single dose, although they may also be given in two or more closely spaced doses.
- Lysis of gonadotropes has been observed to be very rapid (on the order of ten minutes.)
- the two components - the ligand and die lytic peptide may optionally be administered as a fusion peptide, or they may be administered separately, wim the ligand administered slightly before the lytic peptide, to activate cells widi receptors for the ligand, and thereby make those cells susceptible to lysis by the lytic peptide.
- a linking moiety is not necessary to join the ligand to die lytic peptide: one may be bonded directly to the other, without the need for any intervening linkage; bonding is preferably performed by bonding one end of the ligand to one end of die peptide, not by bonding to die middle of either.
- the toxin, the lytic peptide does not need a translocation domain, and need not be internalized, as it binds to and acts directly on the activated cell membrane to cause lysis.
- D-amino acid form of GnRH will bind to gonadotropes in the pituitary and to GnRH neurons in the brain. It is also known that the D-amino acid forms of lytic peptides have essentially die same propensity to lyse cell membranes as do die L-amino acid forms. Compounds of the present invention (whedier administered as a fusion peptide or separately) may therefore be administered eidier in L-form or D-form.
- D-form peptides al iough generally more expensive than L-form, have the advantage diat they are not degraded by normal enzymatic processes, so that ie D-form peptides may therefore be administered orally and generally have a longer biological half-life.
- Oral administration of the D-form peptide may be enhanced by linking die peptide/hormone fusion product to a suitable carrier to facilitate uptake by the intestine, for example vitamin B 12 , following generally the B ]2 -conjugation technique of G.
- Russell-Jones et al. "Synthesis of LHRH Antagonists Suitable for Oral Administration via the Vitamin B n Uptake System," Bioconjugate Chem., vol. 6, pp. 34-42 (1995).
- GnRH or GnRH analogs may be used in the present invention. It has been reported diat substitutions at die 6 and 10 positions of the GnRH decapeptide can produce "superagonists" having greater binding affinity to die GnRH receptor than does GnRH itself. These "superagonists” include goserelin, leuprolide, buserelin, and nafarelin. See U.S. Patent 5,488,036.
- diat die mechanism underlying the invention is as follows: GnRH activates gonadotropic cells in the pituitary gland, as well as neuroendocrine GnRH neurons in the brain.
- the activated cells have substantially increased susceptibility to lysis by a lytic peptide.
- the lytic peptide then preferentially destroys (or severely damages) tiiese activated cells.
- FSH follicle stimulating hormone
- LH luteinizing hormone
- die ligand and die lytic peptide may be administered separately, it is preferred to link die two in a single molecule, because such a linkage greatly increases the effective concentration of the lytic peptide in die vicinity of ligand-activated cells.
- mis increase in the effective lytic peptide concentration can obviate the need for activation of die cells, allowing the peptide to be linked to a binding site of a ligand alone, witiiout needing to include the "remainder" of a native ligand diat would normally be needed for activating the target cells.
- This linkage may be in either order: for example, GnRH/peptide or peptide/GnRH. Examples are GnRH/hecate (SEQ. ID NO. 3) and hecate/GnRH (SEQ. ID NO. 4). Note that no intermediate linker is necessary, and that the carboxy terminus of one of the two peptides may be bonded directly to the amino terminus of the other.
- the pituitary gland of an adult female rat was harvested and divided into six sections of approximately equal size. One section was placed in each of six wells containing tissue culture medium at 37°C. A different treatment was applied to each well, as described below.
- Treatment 1 applied tissue culture medium alone as a control. The histology of mis tissue after treatment appeared normal.
- Treatment 2 was an application of 5 nanograms of GnRH (SEQ. ID NO. 1) per mL of medium. The histology of this tissue after treatment was normal; a small degree of cellular vacuolization was noted. For comparison, the concentration of GnRH in normal, untreated rats varies from as low as 1 ng/mL to as high as 20 ng/mL during the LH surge phase of the estrous cycle.
- Treatment 3 was an application of 50 ⁇ M of the lytic peptide hecate (SEQ. ID NO.
- Treatment 4 was an initial application of 5 nanograms of GnRH per mL of medium for 15 minutes. Following this incubation, die medium containing GnRH was removed, and the tissue was washed once with plain medium. This medium was men removed, and was replaced widi medium containing 50 ⁇ M of the lytic peptide hecate. Widespread basophilic
- Treatment 5 was an application of 50 ⁇ M of the fusion peptide modified GnRH/hecate (SEQ. ID NO. 3). Widespread basophilic (gonadotropic) cellular destruction was observed after the treatment.
- Treatment 6 was an initial application of the fusion peptide GnRH/hecate (SEQ. ID NO. 3
- Example 7 Two sexually immature female rats from the same litter (age 33 days) were given two intravenous injections of saline control solution 24 hours apart. After the rats reached breeding age, they were examined 105 days post-inoculation. The external genitalia appeared normal. During a fourteen-day monitoring period 107 days to 121 days post-inoculation, each of die control rats completed two estrous cycles. The rats were then sacrificed and necropsied. The reproductive organs appeared histologically normal.
- Example 8 Two sexually immature female rats from the same litter (age 33 days) were given two intravenous injections of saline control solution 24 hours apart. After the rats reached breeding age, they were examined 105 days post-inoculation. The external genitalia appeared normal. During a fourteen-day monitoring period 107 days to 121 days post-inoculation, each of die control rats completed two estrous cycles. The rats were then sacrificed and necropsied. The reproductive organs appeared histologically normal.
- Example 8
- Example 7 Two sexually immature female rats from the same litter as those of Example 7 (age 33 days) were given two intravenous injections of 500 ⁇ g GnRH/hecate fusion peptide in saline 24 hours apart. After the rats reached breeding age, diey were examined 105 days post- inoculation. The external genitalia appeared small. Unlike the control rats, insertion of a cotton-tipped swab into the vagina was difficult. During a fourteen-day monitoring period 107 days to 121 days post-inoculation, neither of the treated rats demonstrated estrous or metestrous. The rats were then sacrificed and necropsied. The peptide-treated rats had unned, inactive uterine and oviductal epidielia. Their ovaries contained no large follicles, and had a high number of atretic follicles (i.e., those diat had failed to ovulate).
- Eighteen sexually mature, mixed breed, female rats were randomly assigned to one of six groups containing three rats each. Each group of rats received a double treatment intravenously, as described below. Two weeks after the treatment, the rats were sacrificed and necropsied. The reproductive and endocrine organs were sectioned, weighed, and examined histologically.
- Treatment 9 was a saline control.
- the rats in this group exhibited normal ovarian function (e.g., normal follicles and new corpora lutea).
- the pituitaries from this group were of normal size. Histology showed a normal number of pituitary basophilic cells.
- Treatment 10 was injection with a total of 1.0 mg GnRH/hecate fusion peptide in saline, divided into two equal 0.5 mg injections administered 24 hours apart.
- the rats in this group showed an arrest of normal ovarian follicular development. Few corpora lutea were present, and those tiiat were present appeared old. Follicles were large, and had not ruptured. Uterine morphology was consistent with hormonal inactivity.
- the pituitaries from this group were slightly smaller than die pituitaries from the saline control group. Histology revealed a 60% to 70% reduction in die number of pituitary basophilic cells compared to die controls.
- Treatment 11 was injection of 100 ⁇ L of a 1.35 mM solution of GnRH (162 ⁇ g) in saline, followed 15 minutes later by injection with 100 ⁇ L of a 1.35 mM solution of hecate (337 ⁇ g) in saline. The same two-step treatment was repeated 24 hours later.
- the rats in this group showed altered ovarian histology. Few corpora lutea were present, and those diat were present appeared old. Follicles were large, and had not ruptured. Uterine morphology was consistent with hormonal inactivity. The pituitaries and die pituitary histology were similar to those observed in Treatment 10.
- Treatment 12 was injection of 100 ⁇ L of a 1.35 mM solution of hecate (337 ⁇ g) in saline. The treatment was repeated after 24 hours. The rats in this group exhibited normal ovarian function (e.g., normal follicles and new corpora lutea). The pituitaries and the pituitary histology were similar to those observed in Treatment 9.
- Treatment 13 was injection of 100 ⁇ L of a 1.35 mM solution of GnRH (162 ⁇ g) in saline. The treatment was repeated after 24 hours. The rats in this group exhibited normal ovarian function (e.g., normal follicles and new corpora lutea). The pituitaries and die pituitary histology were similar to those observed in Treatment 9.
- Treatment 14 was identical to Treatment 10, except that the GnRH/hecate fusion peptide was further purified by HPLC.
- the rats in this group showed an arrest of normal ovarian follicular development. Few corpora lutea were present, and those diat were present appeared old. Follicles were large, and had not ruptured. Uterine morphology was consistent with hormonal inactivity. The pituitaries and die pituitary histology were similar to those observed in Treatment 10.
- Tissue and cell specificity of cytotoxic conjugates could be further enhanced by using various hormones or hormone analogs coupled to a lytic peptide.
- hormones or hormone analogs coupled to a lytic peptide Some examples follow.
- For fertility control both die pituitary and the central GnRH neuronal component of the reproductive axis are selectively damaged by GnRH-hecate conjugate. Few cells in the central nervous system should be damaged by this treatment, because the chicken ⁇ GnRH and lamprey III GnRH forms are the primary molecules affecting brain function in most mammals. Fertility control may also be selectively accomplished by treating animals with a bLH-hecate conjugate; this compound should specifically affect GnRH neurons controlling reproduction and die gonads. (Odier lytic peptides may be used in place of hecate in these conjugates.)
- compositions of the present invention may be administered as described, or as pharmaceutically acceptable salts.
- the compositions may be administered intravenously, subcutaneously, intramuscularly, cr (especially when in D-amino acid form and complexed widi a carrier such as vitamin B n ) orally.
- Applications of the present invention include long-term contraception or sterilization in humans; and long-term contraception or sterilization in domesticated or wild mammals.
- Domesticated mammals in which this invention may be used include, for example, dogs, cats, cattle, horses, pigs, and sheep.
- long-term replacement hormone therapy may be needed to prevent undesirable side effects, such as premature menopause.
- Administration of gonadotropic hormones in a sterilized individual will temporarily restore fertility if desired. The sterilization is reversible in this sense.
- mis invention may be used in die humane population control of an unwanted introduced species.
- Examples 15-22 Eight sexually mature, Sprague-Dawley female rats were randomly assigned to one of eight treatments. Each group of rats received a single treatment intravenously, as described below. Rats were sacrificed and necropsied eidier 48 or 96 hours after treatment. The ovaries, uterus, pancreas, liver, spleen, lungs, heart, thyroid, and adrenal glands were fixed in 10% buffered formalin; sectioned; and stained with H&E (hematoxylin and eosin) stain; except diat die pituitary glands were stained widi PAS (periodic acid-Schiff) stain with no counter-stain. The treatments were selected so diat each animal received an equimolar amount of the compound widi which it was treated.
- H&E hematoxylin and eosin
- Treatments 15 and 16 were IV-injection widi 674 ⁇ g of D-hecate in 200 ⁇ L saline (1.35 mM). The rat in treatment 15 was sacrificed 48 hours after injection, and the rat in treatment 16 was sacrificed 96 hours after injection. No gross lesions were noted in die organs of either animal. The pituitary glands of both rats contained a normal number of PAS- positive cells. Treatments 17 and 18 were IV-injection with 334 ⁇ g of GnRH in 200 ⁇ L saline
- the rat in treatment 17 was sacrificed 48 hours after injection, and die rat in treatment 18 was sacrificed 96 hours after injection. No gross lesions were noted in the organs of either animal.
- the pituitary glands of both rats contained a normal number of PAS- positive cells.
- Treatments 19-22 were IV-injection with 1 mg GnRH -hecate fusion peptide (SEQ. ID NO. 3) in 100 ⁇ L saline (2.7 mM).
- the rats in treatments 19 and 20 were sacrificed 48 hours after injection, and die rats in treatments 21 and 22 were sacrificed 96 hours after injection. No gross lesions were noted in die organs of any of the four animals, other than die pituitary.
- the pimitary glands of the animals from treatments 19 and 20 were slightly enlarged, hyperemic, and edematous.
- the pituitary glands of the animals from treatments 21 and 22 were slightly hyperemic, but of expected size.
- LH, FSH, and MSH are glycopeptide hormones; cells containing these hormones stored in their secretory vacuoles stain positive widi PAS.
- Hecate is an amphipafhic lytic peptide diat acts on cell membranes without being internalized. It is a synthetic peptide analog of melittin, the primary toxin in honeybee venom. Hecate is believed to act by disrupting cell membranes.
- the structure of the modified GnRH-hecate conjugate used in these studies was SEQ. ID NO. 3.
- Examples 25-32 We studied in vitro lysis of bovine luteal cells with GnRH-hecate conjugate and wid hecate-bLH conjugate (SEQ. ID NO. 12).
- the bLH component of the conjugate is a 15-mer fragment of the beta chain of luteinizing hormone, SEQ. ID NO. 11).
- Small luteal cells were collected from cattle corpora lutea post-slaughter. Small luteal cells are rich in LH receptors, and were found to be highly susceptible to lysis by die hecate-bLH conjugate. Small luteal cells in culture were incubated with one of the following treatments for 22 hours, and were then examined for viability using Trypan Blue exclusion and release of lactic dehydrogenase.
- Treatment 25 control no additional treatment (media alone) Treatment 26 10 ng bLH (positive control) Treatment 27 hecate-bLH, 10 ⁇ M
- Treatment 28 hecate-bLH, 5 ⁇ M Treatment 29 hecate-bLH, 1 ⁇ M Treatment 30 hecate (alone), 10 ⁇ M Treatment 31 hecate (alone), 5 ⁇ M Treatment 32 hecate (alone), 1 ⁇ M
- Granulosa cells were isolated from bovine pre-ovulatory follicles. (Granulosa cells are hormonally active cells with numerous LH receptors.) Our experiments with granulosa cells were otherwise generally similar to those described above for
- the pituitaries were processed for histological analysis of PAS-stained cells and for cells stained immunocytochemically for bLH, BFSH (bovine follicle stimulating hormone), adrenocorticotropic hormone, and other proopiomelanocortin peptide products (most notably alpha-melanocyte stimulating hormone (MSH)), thyroid stimulating hormone (TSH), prolactin (PRL), vasopressin (VP), oxytocin (OXY) or growth hormone (GH).
- MSH alpha-melanocyte stimulating hormone
- TSH thyroid stimulating hormone
- PRL prolactin
- VP vasopressin
- OXY oxytocin
- GH growth hormone
- Equus caballus Further support of proposed evolutionary relationships for proopiomelanocortin, oxytocin and vasopressin neurons," Brain, Beh. & Evol. , vol. 33, pp. 193-204 (1989).
- Treatment 36 1.62 ⁇ g GnRH (the molar equivalent to the amount of GnRH in Treatment 37) (one rat)
- Treatment 38 0.03 ⁇ g GnRH, followed 11 minutes later by 0.337 ⁇ g hecate
- VP expression probably in corticotropin-releasing neurons, may cause a shift in the post-translational processing of proopiomelanocortin peptide products in the pars distalis, since GnRH-hecate and GnRH + hecate treatments reduced adrenocorticotropic hormone levels and increased me number of alpha-MSH-stained cells in this subdivision of the pimitary. No pathological changes were noted in any o er tissues.
- Treatment 42 1.0 mg GnRH-hecate Treatment 43 1.5 mg GnRH-hecate.
- GnRH-hecate produced a large number of GnRH -receptor-containing neurons having abnormal morphologies, including distortion of the somatic portion of die cells, and degeneration of neurites.
- 66% and 87% of the GnRH- receptor-containing neurons were abnormal in the rats that had received 1.0 and 1.5 mg of GnRH-hecate, respectively.
- Axonal degeneration in the 1.5 mg GnRH-hecate group was accompanied by over 90% reduction in median eminence staining for GnRH.
- the GnRH-hecate treatment increased the number of PAS-stained pimitary cells in the pars distalis to 177% of that for control rabbits; this increase appeared to reflect increased numbers of cells staining alpha-MSH, and reduced numbers of cells staining for LH.
- the number of ovulation sites in rabbits in Examples 47 and 48 treated with 10 mg GnRH-hecate were reduced as compared to saline controls.
- lytic peptides act by disrupting cell membranes. "Resting" eukaryotic cells protect themselves through tiieir ability to repair the resulting membrane damage. By contrast, activated cells (e.g., cells stimulated by GnRH) are unable (or less able) to repair damaged membranes. Because GnRH -activated pimitary cells have a diminished capacity to repair membranes, they are preferentially destroyed by lytic peptides, while adjacent non-activated cells repair their membranes and survive.
- Lytic peptides are small, basic peptides. Native lytic peptides appear to be major components of the antimicrobial defense systems of a number of animal species, including tiiose of insects, amphibians, and mammals. They typically comprise 23-39 amino acids, although they can be smaller. Th y have the potential for forming amphipathic alpha-helices. See Boman et al., "Humoral immunity in Cecropia pupae," Curr.

- Known amino acid sequences for lytic peptides may be modified to create new peptides that would also be expected to have lytic activity by substitutions of amino acid residues that preserve the amphipathic nature of the peptides (e.g., replacing a polar residue with another polar residue, or a non-polar residue widi anodier non-polar residue, etc.); by substitutions that preserve the charge distribution (e.g., replacing an acidic residue with another acidic residue, or a basic residue with another basic residue, etc.); or by lengthening or shortening me amino acid sequence while preserving its amphipathic character or its charge distribution.

- Families of naturally-occurring lytic peptides include the cecropins, the defensins, the sarcotoxins, the melittins, and the magainins. Boman and coworkers in Sweden performed the original work on the humoral defense system of Hyalophora cecropia, the giant silk moth, to protect itself from bacterial infection.

- Defensins originally found in mammals, are small peptides containing six to eight cysteine residues. Ganz et al, "Defensins natural peptide antibiotics of human neutrophils," J. Clin. Invest. , vol. 76, pp. 1427-1435 (1985). Extracts from normal human neutrophils contain three defensin peptides: human neutrophil peptides HNP-1, HNP-2, and HNP-3.

- Lytic peptides such as are known generally in the art may be used in practicing the present inventions.
- Selective toxicity to ligand-activated cells is desirable, especially when die ligand and peptide are administered separately.
- Selective toxicity is less important when the ligand and peptide are linked to one another, because in that case the peptide is effectively concentrated in die immediate vicinity of cells having receptors for the ligand.
- Examples of such peptides are those designated D1A21 (SEQ. ID NO. 5), D2A21 (SEQ. ID NO. 5), D2A21 (SEQ. ID NO. 5), D2A21 (SEQ. ID NO. 5), D2A21 (SEQ. ID NO. 5), D2A21 (SEQ. ID NO. 5), D2A21 (SEQ. ID NO. 5), D2A21 (SEQ. ID NO. 5), D2A21
