BIOLOGICALLY ACTIVE SILICON-COMPOUNDS AND THEIR PHARMACEUTICAL AND COSMETICAL USE

Silicon compound of general formula a), in which A, B, C, D are radicals which are different from OH and are covalently bonded to Si; two or three of these bond that are linked to Si are Si-O-C, Si-S-C or Si-N-C type bonds and are hydrolyzable in vivo, forming Si-OH bonds that are biologically activ...

More Information
Summary:Silicon compound of general formula a), in which A, B, C, D are radicals which are different from OH and are covalently bonded to Si; two or three of these bond that are linked to Si are Si-O-C, Si-S-C or Si-N-C type bonds and are hydrolyzable in vivo, forming Si-OH bonds that are biologically active especially when in contact with living tissue, the A and D bonds of formula b) being invariably hydrolyzable; at least one of the hydrolyzable bonds corresponds to an acyloxy, aryloxy or vinyloxy radical; at least one of the compounds obtained after hydrolysis of the hydrolyzable bonds is a stabilizer, and the non-hydrolyzable bonds, which are of the Si-C type, correspond to hydrocarbon or fluorocarbon radicals for which Si is not directly linked to the phenyl ring.
