Semi-synthesis of A23187 (calcimycin) analogs. IV. Cation carrier properties in mitochondria of analogs with modified benzoxazole rings. Antimicrobial activity.

Abstract

The transporting abilities in the mitochondrial membrane for Ca++ and Mg++ of ten semi-synthetic analogs A23187 (calcimycin) and X14885A are compared. Analogs classified as efficient divalent cation carrier retained the calcimycin antimicrobial activity against three Gram-positive strains tested.
