Quartromicin1, a complex of novel antiviral antibiotics: I. Production, isolation, physico-chemical properties and antiviral activity

Abstract

A strain of Amycolatopsis orientalis No. Q427-8 (ATCC 53884) was found to produce a complex of new antiviral antibiotics, quartromicin which consisted of at least six components A1, A2, A3, D1, D2 and D3. Structural studies suggested that they are a novel type of molecules unrelated to any known antibiotics. Each component of quartromicin exhibited antiviral activity against herpes simplex virus type 1, influenza virus type A and human immunodeficiency virus. © 1992, JAPAN ANTIBIOTICS RESEARCH ASSOCIATION.
