Antifungal Macrolides Kongjuemycins from Coral-Associated Rare Actinomycete Pseudonocardia kongjuensis SCSIO 11457
Organic Letters(2022)
Abstract
Four new macrolides, kongjuemycins A and B1–B3 (1–4), were isolated from a coral-associated actinomycete Pseudonocardia kongjuensis SCSIO 11457. Their structures were characterized by comprehensive spectroscopic analysis and single-crystal X-ray diffraction. The absolute configurations of 1 and 2 were established by electronic circular dichroism calculation and the modified Mosher’s method. Kongjuemycins displayed antifungal activity against three phytopathogenic fungi.
