Five series of compounds (4-9) derived from N-(chlorocarbonyl) isocyanate have been synthesized and evaluated for their ability to inhibit the enzyme acyl-CoA:cholesterol O-acyltransferase and lower plasma cholesterol levels in cholesterol-fed rats. Structure-activity relationships indicate that the imino dicarboxylates (6 and 7) and the oxycarbonyl thiocarbamates (8) are the most potent and efficacious
developed a chemoselective deprotection and nucleophilic substitution of acetals from aldehydes in the presence of ketals. This article describes the highly discriminative and chemoselective transformations of acetals bearing different substitution patterns, different types of acetals, as well as mixed acetals. These reactions can achieve the transformations that cannot be attained by conventional methods,
The present invention relates to a mixed surfactant system, and particularly to a mixed surfactant system which comprises an anionic surfactant and a compound comprising at least one kind of non-ionic group or cationic group, and which thus increases cleaning power of the anionic surfactant, increases stability to hard water, lowers surface tension and cmc, and can control initial foamability and foam stability by the mixing ratio of the non-ionic surfactant and the cationic surfactant that can be added together, and that is therefore very useful for a detergent of solid, liquid, gel, or paste types.
