Rifampin was glycosylated by a pathogenic species of Nocardia, i.e., Nocardia brasiliensis. The structures of two glycosylated compounds (RIP-1 and RIP-2) isolated from the culture broth of the bacterium were determined to be 3-formyl-23-(O-[beta-D-glucopyranosyl])rifamycin SV and 23-(O-[beta-D-glucopyranosyl])rifampin, respectively. Both compounds lacked antimicrobial activity against other gram-positive bacteria as well as the Nocardia species.
利福平被巴西诺卡氏菌这一病原菌糖基化。从该细菌培养液中分离出的两种糖基化化合物(RIP - 1和RIP - 2)的结构分别被确定为3 - 甲酰基 - 23 -(O - [β - D - 吡喃葡萄糖基])利福霉素SV和23 -(O - [β - D - 吡喃葡萄糖基])利福平。这两种化合物对其他革兰氏阳性菌以及诺卡氏菌属均无抗菌活性。
