title: Atropisomeric myristinins: selective COX-2 inhibitors and antifungal agents from Myristica cinnamomea.
abstract: The first naturally occurring atropisomeric flavans, myristinins B (2), C (2a), E (4), and F (4a), together with their corresponding trans-isomers, myristinins A (1) and D (3), were isolated from the CH(2)Cl(2) extract of Myristica cinnamomea fruits. Compounds 1, the mixture of 2 and 2a, and the mixture of 4 and 4a, exhibited antifungal activity against Candida albicans with IC(50) values ranging from 5.9 to 8.8 microg/mL, and they selectively inhibited the enzyme cyclooxygenase-2 (COX-2).
