Dianemycin (Nanchangmycin free acid), produced by Streptomyces nanchangensis NS3226, inhibits gram-positive bacteria[1]. Dianemycin is a broad spectrum antiviral active against Zika virus[2]. Bacteria[1] Zika virus[2]

Dianemycin (Nanchangmycin) can be used as a growth promotant in poultry and to cure coccidiosis in chickens. Dianemycin is active against drug resistant strains of malaria[1]. Dianemycin (Nanchangmycin) as a potent inhibitor of Zika virus (ZIKV) entry across all cell types tested including physiologically relevant primary cells. Dianemycin potently reduces infection of all three strains of ZIKV across all three cell types. The IC50s for infection are between 0.1 and 0.4 μM while Dianemycin has low toxicity in these ranges. In addition, DENV is inhibited by Dianemycin across cell types[2].
