摘要: A new pyridine derivative, 5-(2’-hydroxypropyl)pyridin-3-ol (1), with seven known alkaloids, 3-hydroxy-5-methyl-5,6-dihydro-7H-cyclopenta[b]pyridin-7-one (2), penicillenol A1 (3), penicillenol A2 (4), a mixture of quinolactacin A1 (5a) and quinolactacin A2 (5b), and a mixture of quinolactacin C1 (6a) and quinolactacin C2 (6b), were isolated from the culture broth of a marine-derived fungus Xylariaceae sp. SCSGAF0086. Their structures were elucidated by spectroscopic methods. Compound 2 showed weak antimicrobial activity against Bacillus subtilis, and a mixture of 6a and 6b exhibited strong antifouling activity toward Bugula neritina larval settlement.
