Five anti-Gram-positive bacterial components were isolated from the fermented broth of Streptomyces rochet var. volubilis and named as T-2636 A, B, C, D and E. T-2636 A, C, D and E are N-containing neutral lipophilic antibiotics and have the molecular formulae of C27H35NO8, C25H33NO7, C27H37NO8 and C26H37NO6, respectively. T-2636 B, C43H72O17, is a neutral macrolide. T-2636 M obtained from the mycelium was assumed to be a polyene macrolide. The physico-chemical characterization of these components reveals that T-2636 B, D and E are new antibiotics and that T-2636 A, C, D and E belong to the lankacidin group. T-2636 A and C are identical with bundlin B and lankacidin, respectively.
