Title: Novel antibiotics, furaquinocins A and B. Taxonomy, fermentation, isolation and physico-chemical and biological characteristics. Author: Komiyama K, Funayama S, Anraku Y, Ishibashi M, Takahashi Y, Omura S. Journal: J Antibiot (Tokyo); 1990 Mar; 43(3):247-52. PubMed ID: 2324009. Abstract: Two novel antibiotics, furaquinocins A and B were isolated from the culture broth of Streptomyces sp. KO-3988. These antibiotics possess cytocidal activities against HeLa S3 cells in vitro at concentrations of 3.1 micrograms/ml for A and 1.6 micrograms/ml for B. Neither substance possessed antimicrobial activities against Gram-positive and Gram-negative bacteria, fungi or yeast at a concentration of 1,000 micrograms/ml.[Abstract] [Full Text] [Related] [New Search]
