Abstract
A complex of the new antitumor antibiotics (WF-1360, WF-1360A, B, C, D, E and F) was produced by Rhizopus sp. No. F-1360. Structural studies of these compounds suggested that they were novel 16-membered-ring lactones having an oxazole ring in their structures. WF-1360 was found to be identical with rhizoxin (1) and WF-1360B, C, E and F were determined to be homologues of 1 with structures 2, 3, 4 and 5, respectively. These compounds were cytotoxic when tested on P388 leukemia cells in vitro. WF-1360 was highly active against leukemia L1210 and melanoma B16. They also exhibited potent antifungal activities, but weak antimicrobial activities against some Gram-positive or negative bacteria.This publication has 1 reference indexed in Scilit:
