개요
Gramicidin S was found in the culture broth of Bacillus brevis by Gause of the USSR Academy of Medical Sciences in 1944. It was later found by Otani of Osaka University in the cells of the Nagano strain of the same species. The antibiotic is a basic peptide showing strong activity against gram-positive bacteria and considerable activity against gramnegative cocci and Mycobacterium. Gramicidin S is rather toxic but is not absorbed orally; it is used topically as an ointment or as eye or ear drops in combination with other antibacterial drugs.정의
A cyclic peptide that acts on gram-positive bacteria.Purification Methods
Gramicidin S crystallises from EtOH. The di-HCl crystallises from EtOH (+ few drops of HCl) with m 277-278o (see below). [NMR: Gibbons et al. Nature 227 840 1970, Beilstein 26 III/IV 4273.]그라미시딘C 준비 용품 및 원자재
