Antiproliferative polyketides from fungus Xylaria cf. Longipes SWUF08-81 in different culture media

Kittiwan Sresuksai, Sasiphimol Sawadsitang, Phongphan Jantaharn, Pakin Noppawan et autres

Abstract Bioactive compounds from the wood-decay fungus Xylaria cf. longipes SWUF08-81, cultivated in three different culture media (GM, YM and PDB), were isolated. Their structures and stereochemistry were deduced from spectroscopic and MS data analysis, together with quantum chemical calculations of 13C …
