New alkylated hydroquinones violaceoid A (1), violaceoid B (2), and violaceoid C (3), an alkylated phenol violaceoid D (4), and a cyclohexenoid violaceoid E (5) were isolated from a culture broth of Aspergillus violaceofuscus Gasperini isolated from moss. The structures were identified by
Two new cyclohexenones (antheminones A and B) and a new cyclohexanone, (antheminone C) along with five known compounds were isolated from the leaves of Anthemis maritima L. The structures were mainly deduced from extensive 1D and 2D NMR spectroscopy and mass spectrometry. The new compounds were
OBJECTIVE
Discovery of novel series of colchicine binding site inhibitors (CBSIs).
METHODS
Isoxazoline 3a-d, pyrazoline 4a-b, 7a-f and 8a-f, cyclohexenone 9a-b and 10a-b or pyridine derivatives 11a-b were synthesized and evaluated for their inhibition of tubulin polymerization and cytotoxicity. Most
