NOVEL CYCLIC PEPTIDE COMPOUND, METHOD FOR PRODUCING SAME, ANTI-INFECTIVE AGENT, ANTIBIOTIC-CONTAINING FRACTION, ANTIBIOTIC, METHOD FOR PRODUCING ANTIBIOTIC, ANTIBIOTIC-PRODUCING MICROORGANISM, AND ANTIBIOTIC PRODUCED BY SAME

摘要

Provided are: a novel compound having a structure different from that of existing drugs; a novel microorganism capable of producing the novel compound; and further; a novel compound effective to a multiple-drug-resistant bacterium. To provide a novel compound having a high therapeutic effect which can be expected to have a low hurdle for practical realization by selecting an intended compound from many candidate compounds based not only on an antibacterial activity but also on evaluation including a therapeutic effect, a cyclic peptide compound shown by the following formula (1) or a pharmaceutically allowable salt thereof and a microorganism with Accession No. NITE BP-870 or a microorganism mutated naturally or artificially therefrom are provided. (In the formula (1), R1 represents an acyl group having 7, 8, or 9 carbon atoms and optionally containing a substituent group; R2 represents a methyl group or a hydrogen atom; and R3 represents an ethyl group or a methyl group.)
