摘要:
Disclosed are methods of preparing monoalkyl Group VA metal dihalide compounds in high yield and high purity by the reaction of a Group VA metal trihalide with an organo lithium reagent or a compound of the formula RnM1X3−n, where R is an alkyl, M1 is a Group IIIA metal, X is a halogen and n is an integer fro 1 to 3. Such monoalkyl Group VA metal dihalide compounds are substantially free of oxygenated impurities, ethereal solvents and metallic impurities. Monoalkyl Group VA metal dihydride compounds can be easily produced in high yield and high purity by reducing such monoalkyl Group VA metal dihalide compounds.

摘要:
Arsenic trioxide, an inorganic compound, is commercially available anti-cancer agent but it carries significant toxicity. Organic arsenicals, on the other hand, are much less toxic, to the extent that the methylation of inorganic arsenic in vivo into organic arsenicals has been considered a detoxification reaction. New organic arsenic derivatives have been synthesized, including S-dimethylarsino-glutathione, S-dimethylarsino-thiosuccinic acid and S-dimethylarsino-thiobenzoic acid, and established its potent in vitro cytotoxic activity against numerous human tumor cell lines, both of solid and hematological origin, as well as against malignant blood cells from patients with leukemia. Results form a basis for the development of S-dimethylarsino-glutathione, S-dimethylarsino-thiosuccinic acid, S-dimethylarsino-thiobenzoic acid, and other organic arsenicals as an anti-cancer therapy, combining high efficacy with very low, if any, toxicity.
