Trichostatin(s)
Title: Trichostatin(s)
Additional Names: Antibiotic A-300; A-300-I
Literature References: Antifungal antibiotic isolated from metabolites of Streptomyces hygroscopicus. It is composed of trichostatins A (major), B, the ferric chelate of trichostatin A, and C, the first glycosyl hydroxamate from a natural source. Isoln of A and B: N. Tsuji et al., JP Kokai 74 14691, C.A. 81, 48547h (1974). Structural elucidation of A and B: eidem, J. Antibiot. 29, 1 (1976). Isoln and structure of C: N. Tsuji, M. Kobayashi, ibid. 31, 939 (1978).
