Abstract

Abstract Various types of biological treatments, including antineoplastic treatments with antineoplastic drugs, can result in damage to the blood-forming function of the bone marrow. This damage can be reversed, at least to some degree, with an effective amount (preferably an extremely low dose) of a pharmaceutically acceptable dithiocarbamic compound, including a compound of the formula R1R2NCSSM or R1R2NCSS-SCSNR3R4, wherein R1, R2, R3, and R4 are the same or different aliphatic or cycloaliphatic or heterocycloaliphatic groups, unsubstituted or substituted by hydroxyl, or one of R1 and R2 and one of R3 and R4 can be H, or R1 and R2 or R3 and R4, taken together with the N atom upon which the pair of R groups is substituted, can be a 5- or 6-member N-heterocyclic ring which is aliphatic or aliphatic interrupted by a ring oxygen or second ring nitrogen, and M is H or one equivalent of a pharmaceutically acceptable cation, in which case the rest of the molecule is negatively charged. The dosage in mammals can range from about 0.001 to 30 mg/kg of body weight. For larger mammals, including humans, a typical dosage unit is less than 10 mg/kg, e.g. <3 mg/kg. The dosage unit can be dissolved in a suitable pharmaceutically acceptable carrier (e.g. an aqueous medium) and is then preferably administered intravenously within 8 hours of the administration of the agent which can cause bone marrow damage. The extremely low dosages particularly preferred in this invention do not cause any significant side effects.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 75 words
A process for the treatment of myelosuppression resulting from a toxic side effect of a cytotoxic streptomyces-produced antibiotic derivative administered to a human, said process comprising administering about 0.01-10 mg/kg of body weight of said human, of a compound of the formula: ##STR8## wherein M + is a pharmaceutically acceptable cation, and R 1 and R 2 are the same or different and represent C 1 -C 6 lower aliphatic or hydroxy-substituted lower aliphatic groups.
Claim 2
Dependent Claim 75 words
A process for the treatment of myelosuppression resulting from a toxic side effect of a cytotoxic streptomyces-produced antibiotic derivative administered to a human, said process comprising administering about 0.01-10 mg/kg of body weight of said human, of a compound of the formula: ##STR8## wherein M + is a pharmaceutically acceptable cation, and R 1 and R 2 are the same or different and represent C 1 -C 6 lower aliphatic or hydroxy-substituted lower aliphatic groups.
Claim 3
Dependent Claim 12 words
The process of claim 1 wherein the antibiotic derivative is doxorubicin hydrochloride.
