Structures of novel antibiotics, furaquinocins A and B

Structures of novel citocydal antibiotics furaquinocins A and B, isolated from the fermentation broth of Streptomyces sp. KO-3988, was elucidated on the basis of spectroscopic analyses.

Structure of phenazinomycin, a novel antitumor antibiotic

Abstract Structure and absolute configuration of a novel antitumor antibiotic phenazinomycin was determined on the basis of the spectral data and chemical degradation. Phenazinomycin is the first phenazinone alkaloid which possesses sesquiterpene moiety in its structure.

Furaquinocins A-G: relative and absolute stereochemistry

Abstract The complete relative and absolute stereochemistry of furaquinocins A-G, a family of cytotoxic antibiotics, have been assigned via a combination of X-ray crystallography, NMR analysis of the derived Mosher esters, and chemical correlation.
