Deisovalerylblastmycin produced by Streptomyces SP.
A new antifungal antibiotic was isolated from the fermentation broth of Streptomyces sp. 5140-A1. Degradation studies of the crystalline antibiotic, m.p. 186 approximately 188 degrees C, C21H28O8N2, suggested Piricularia oryzae and less toxicity against killfish than antimycin A--blastmycin antibiotics.
متن کاملStreptopyridines, volatile pyridine alkaloids produced by Streptomyces sp. FORM5
Streptomyces sp. FORM5 is a bacterium that is known to produce the antibiotic streptazolin and related compounds. We investigated the strain for the production of volatiles using the CLSA (closed-loop stripping analysis) method. Liquid and agar plate cultures revealed the formation of new 2-alkylpyridines (streptopyridines), structurally closely related to the already known 2-pentadienylpiperid...
متن کاملKitamycins, new antimycin antibiotics produced by Streptomyces sp.
In the course of our screening program for plant growth inhibitors, Streptomyces sp. K385 isolated from a soil sample collected in OkayamaJapan, was found to produce kitamycin A (1) and B (2), new antimycin type antibiotics, together with known antimycin type antibiotics, antimycin A1? A2a, A3, A4a1?2), urauchimycin B (3)3), and deisovalerylblastmycin (4).4?5) This study describes the fermentat...
متن کاملAL072, a novel anti-Legionella antibiotic produced by Streptomyces sp.
AL072 is a potent anti-Legionella antibiotic produced by Streptomyces strain AL91. The compound was isolated from the fermentation broth with 1 volume of isopropyl alcohol, followed by an ethyl acetate extraction and subsequent concentration under reduced pressure. Purification was performed on an octadecyl silica gel column followed by preparative HPLC. AL072 purified as mentioned above showed...
متن کاملAJI9561, a new cytotoxic benzoxazole derivative produced by Streptomyces sp.
(Traders) 1.0%, yeast extract 0.1%, and CaCO3 0.2% (pH 7.2). The fermentation was carried out at 28°C on a rotary shaker (180 rpm) for 96 hours. The culture broth of Streptomyces sp. AJ9561 (5 liters) was filtered to obtain mycelium, which was extracted with acetone (3 liters) at room temperature. The extract was concentrated in vacuo to an aqueous suspension, which was extracted with EtOAc (50...
