Three new 24,28-dinorolean-3-one derivatives, the remangilones A-C (1-3), were isolated from the dried leaves of Physena madagascariensis using a human mammary carcinoma cell line to guide the isolation. The structures of 1-3 were deduced primarily from NMR studies. Compounds 1 and 3, remangilones A and C, respectively, were found to be cytotoxic against(More)
Two new flavanones (1 and 2) with antibacterial activity were isolated from the methanolic extract of the dried leaves of Physena madagascariensis using activity against Staphylococcus aureus to guide the isolation. A third flavonoid, a flavanone dimer linked by a methylene group (3) was also isolated and proved to be inactive. The structures of 1 and 2(More)
