Abstract A new antifungal macrocyclic lactone maclafungin, belonging to the oligomycin class has been isolated from an actinomycete sp. Y-8521050. The antibiotic, having a molecular formula of C46H80O12, is active against several fungal species. Its structure was elucidated by analysis of 2D NMR experiments.

Abstract Three new antibiotics grividomycins I, II and III belonging to streptogramin class, have been isolated from a Streptomyces sp. HIL Y-8240155. The antibiotics are active against several resistant Gram positive bacteria. The structures of these compounds were elucidated mainly by HREIMS, GCMS and chiral GC.
