New antibiotics having β-lactamase inhibitory activity, i.e. pluracidomycin B, C, and D and their analogs, are of the formula:
wherein either R is carboxymethylsulfinyl, formylsulfinyl, dihydroxymethylsulfinyl, hydroxymethylsulfinyl, carboxymethylthio or dihydroxymethylthio and R is sulfo or R is sulfo and R1 is hydrogen. The antiobiotics and the salts thereof are useful as medicaments, veterinary drugs and disinfectants for inhibiting the growth of both gram-positive and gram-negative pathogenic microorganisms. The invention includes their production, a new microorganism for use in their production, and formulations containing them.
具有β-内酰胺酶抑制活性的新型抗生素,即多效霉素B、C和D及其类似物,其结构式为
其中,R 是羧甲基亚磺酰基、甲酰亚磺酰基、二羟甲基亚磺酰基、羟甲基亚磺酰基、羧甲基硫基或二羟甲基硫基,R 是磺基或 R 是磺基,R1 是氢。这些抗生物质及其盐类可用作药物、兽药和消毒剂,用于抑制革兰氏阳性和革兰氏阴性病原微生物的生长。本发明包括它们的生产、用于生产它们的新微生物以及含有它们的制剂。
