DETAILED DESCRIPTION OF THE INVENTION
The preparation of the compounds of this invention is described in U.S. Patent 4,916,137, which is hereby incorporated herein by reference.
The ability of the compounds of this invention to treat or inhibit neutropenia was evaluated in the 5-fluorouracil (5-FU) induced neutropenia standard pharmacological test procedure which measures a compound's ability to enhance neutrophil recovery post chemotherapy. Based on the results obtained in this test procedure, the compounds of this invention demonstrated a substantial acceleration of neutrophil recovery following administration of 5-FU. The test procedure used and results obtained with a representative compound of this invention are provided below.
Briefly, C3HHeb/Fej male mice, 8-10 weeks of age, were used to evaluate the ability of a compound to accelerate neutrophil recovery post chemotherapy. The mice were routinely housed for ten days prior to testing in order to stabilize their immune responses. The mice were housed 5-per-cage and received food and water ad libitum throughout the experiment. Fluorouracil injection, 500 mg/10 ml, was diluted in phosphate-buffered saline for intraperitoneal injection at 150 mg/kg, 0.5 cc.
Twenty-four hours following 5-FU, the mice were treated with either vehicle or a representative compound of this invention, which was mixed in 0.2% Klucel and sonicated, resulting in a milky white suspension, and 0.2 cc was administered for subcutaneous or oral dosing and 0.5 cc when the compound is dosed intraperitoneally. Compound was either given as a single injection 24 hours following 5-FU, or as multiple daily doses for 10 days beginning 24 hours following 5-FU. A neutrophil recovery curve following 5-FU administration was generated by measuring circulating neutrophils.
Mice were retro-orbitally bled and a 20 p.l sample was taken for measurement of total white blood cells using a Coulter Counter. In addition, a blood smear was also prepared. The slides were stained using Diff Quick and the percent neutrophils was determined by scoring 100, stained, white-blood-cells. The total number of neutrophils per cubic mm was calculated and plotted against time (days post 5-FU).
A dose-related acceleration of neutrophil recovery following 5-FU in mice results from subcutaneous treatment with compound of Example 14 as shown in Table I. The compound of Example 14, when dosed either subcutaneouslv or intraperitoneally, is effective in accelerating neutrophil recovery after 5-fluorouracil treatment in mice as shown in Table II.

A preferred dosage regimen for optimum results would be from about 10 mg to about 50 mg/kg of body weight per day and such dosage units are employed that a total of from about 700 mg to about 3.5 g of the active compound for a subject of about 70 kg of body weight are administered in a 24 hour period.
The dosage regimen for treating neutropenia in mammals may be adjusted to provide the optimum therapeutic response. For example, several divided doses may be administered daily or the dose may be proportionally reduced as indicated by the exigencies of the therapeutic situation. A decidedly practical advantage is that these active compounds may be administered in any convenient manner such as by the oral, intravenous, intramuscular or subcutaneous routes.
The active compounds may be orally administered, for example, with an inert diluent or with an assimilable edible carrier, or they may be enclosed in hard or soft shell gelatin capsules, or they may be compressed into tablets or they may be incorporated directly with the food of the diet. For oral therapeutic administration, these active compounds may be incorporated with excipients and used in the form of ingestible tablets, buccal tablets, troches, capsules, elixirs, suspensions, syrups, wafers and the like. Such compositions and preparations should contain at least 0.1 %
of active compound. The percentage of the compositions and preparations may, of course, be varied and may conveniently be between about 2% to about 60% of the weight of the unit. The amount of active compound in such therapeutically useful compositions is such that a suitable dosage will be obtained. Preferred compositions or preparations according to the present invention are prepared so that an oral dosage unit form contains between about 5 and 200 mg of active compound.
The tablets, troches, pills, capsules and the like may also contain the following:
a binder such as gum tragacanth, acacia, corn starch or gelatin; excipients such as dicalcium phosphate; a disintegrating agent such as corn starch, potato starch, alginic acid and the like; a lubricant such as magnesium stearate; and a sweetening agent such as sucrose, lactose, or saccharin may be added or a flavoring agent such as peppermint, oil of wintergreen or cherry flavoring. When the dosage unit form is a capsule, it may contain, in addition to materials of the above type, a liquid carrier. Various other materials may be present as coatings or to otherwise modify the physical form of the dosage unit. For instance, tablets, pills or capsules may be coated with shellac, sugar or both. A syrup or elixir may contain the active compound, sucrose, as a sweetening agent, methyl and propylparabens as preservatives, a dye and flavoring such as cherry or orange flavor. Of course, any material used in preparing any dosage unit form should be pharmaceutically pure and substantially non-toxic in the amounts used. In addition, these active compounds may be incorporated into sustained-release preparations and formulations.
These active compounds may also be administered parenterally or intraperitoneally. Solutions or suspensions of these active compounds as a free base or pharmacologically acceptable salt can be prepared in water suitably mixed with a surfactant such as hydroxypropylcellulose. Dispersions can also be prepared in glycerol, liquid polyethylene glycols, and mixtures thereof in oils. Under ordinary conditions of storage and use, these preparations contain a preservative to prevent the growth of microorganisms.
The pharmaceutical forms suitable for injectable use include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. In all cases, the form must be sterile and must be fluid to the extent that easy syringability exists. It must be stable under the conditions of manufacture and storage and must be prepared against the contaminating action of microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e.g., glycerol, propylene glycol and liquid poly-ethylene glycol), suitable mixtures thereof, and vegetable oils:
The following are representative examples of compounds of this invention which are useful in treating or inhibiting neutropenia. The preparation of these compounds are described in U.S. Patent 4,916,137, which is hereby incorporated by reference. Examples 1-10, 11, 65-67 and 69-71 are intermediates in the preparation of the exemplified compounds.
