摘要:
A physiologically active compound HS-1 having the following chemical structure is disclosed. This compound is prepared by culturing Chromobacterium violaceum, adding tryptophan and diethyldithiocarbamate (diethyldithiocarbamic acid) to the culture broth for reacting with the cells for producing HS-1 in the cells, and collecting the compound from the culture broth. This novel compound possesses antitumor and antimicrobial activity, and is effective as an antitumor agent or an antimicrobial agent. ##STR1##
摘要:
Antibiotics RK-1061s having a novel chemical structure and a method of production thereof.They have a structural formula represented by general formula(I) wherein A represents R1 or R1CH(OR2)CH2. R2 represents 3-methylglutaric acid residue and R3 represents a sulfate group or a hydrogen atom. The process comprises culturing a ray fungus belonging to the genus Streptomyces and isolating RK-1061s from the culture. Streptomyces sp. SN-1061Ms (FERM BP-5800) is capable of stably producing RK-1061 at a high productivity.
