Anti-glioma trichobamide A with an unprecedented tetrahydro-5H-furo[2,3-b]pyrrol-5-one functionality from ascidian-derived fungus Trichobotrys effuse 4729.

Trichobamide A (1), a novel pyrrocidine alkaloid with an unprecedented tetrahydro-5H-furo[2,3-b]pyrrol-5-one moiety, was isolated from the ascidian-derived fungus Trichobotrys effuse 4729. Trichobamide A (1) showed significant inhibition of the proliferation of two glioma cell lines, U251 and SNB19. It induced the up-regulation of P53 expression, which in turn induces the up-regulation of downstream pro-apoptotic gene expression and the down-regulation of anti-apoptotic gene expression.
