Absolute stereochemistry of immunosuppressive macrolide brasilinolide A and its new congener brasilinolide C.
Brasilinolide A (2) is a 32-membered polyhydroxyl macrolide with immunosuppressive activity isolated from a pathogenic actinomycete, Nocardia brasiliensis IFM0406. The absolute configurations at 26 chiral centers of 2 and its new congener, brasilinolide C (1), were determined on the basis of the spectral data of 1 and degradation products derived from 1 and 2.
