Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， category: piperidines, Which mentioned a new discovery about 27578-60-5
A series of 2- and 3-nitrothiophene-5-carboxamides bearing N-(omega-aminoalkyl) side chains has been prepared by treatment of the thiophenecarbonyl chloride with the appropriate (protected) omega-aminoalkylamine. Analogous N-(oxiranylmethyl)nitrothiophene-5-carboxamides have been synthesized by epoxidation of the corresponding N-allylamide. Compounds in both classes were evaluated in vitro both as radiosensitizers of hypoxic mammalian cells and as selective bioreductively activated cytotoxins. The most potent radiosensitizers were those agents with strong tertiary amine bases or oxiranes in the side chain. Studies in vivo showed that 2-methyl-N-[2-(dimethylamino)ethyl]-3-nitrothiophene-5-carboxamide caused slight radiosensitization of the KHT sarcoma in mice given 0.34 mmol kg-1. However, administration of this and related tertiary amines at higher doses was precluded by systemic toxicity.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, category: piperidines, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 27578-60-5
