Antibiotics from gliding bacteria. No.60. The Tartrolons, New Boron-containing Antibiotics from a Myxobacterium, Sorangium cellulosum.

Abstract

New antibiotics were isolated from the culture broth of the myxobacterium, Sorangium cellulosum, strain So ce 678. The antibiotics were active against Gram-positive bacteria and mammalian cells. They were named tartrolon A and B. Tartrolon B contains a boron atom. The boron binding region of tartrolon is identical with that of boromycin and aplasmomycin.
