Iyini i-Rifamycin S CAS 13553-79-2?

I-Rifamycin S ingumkhiqizo wesizukulwane sesithathu wesigaba semithi ye-rifampicin, esebenza ngempumelelo ephezulu kanye nomsebenzi wokulwa namagciwane obanzi. Izwela kakhulu kumagciwane ahlukahlukene ajwayelekile amelana nemithi. I-Lipomycin B ingena kwi-oxidation, inciphe, kanye ne-hydrolysis ukuze ikhiqize i-rifampicin sodium.

Isicelo

I-Rifamycin S isetshenziswa njengendawo emaphakathi yemithi ukuvimbela umsebenzi webhaktheriya i-RNA polymerase. Ukuvimbela ukuhlanganiswa kwe-RNA yebhaktheriya, ekugcineni kuvimbele ukuhlanganiswa kwamaprotheni adingwa amagciwane, okuholela ekufeni kwebhaktheriya futhi kubonise imiphumela ye-bactericidal.
