Cytotoxic Coumarins from Toddalia asiatica

Abstract

Three new coumarins and 13 known compounds were isolated from the stem bark of Toddalia asiatica. Compounds 1, 3, 8, and 9 showed cytotoxicity against the NCI-H187 cell line with IC₅₀ values ranging from 6 to 9 µg/mL. Compounds 4 and 9 exhibited cytotoxicity against the MCF-7 cell line with IC₅₀ values of 3.17 and 9.79 µg/mL, respectively. Compound 9 also displayed cytotoxic activity against KB cells with an IC₅₀ value of 8.63 µg/mL. In addition, compound 14 showed antimalarial activity against Plasmodium falciparum with an IC₅₀ value of 3.66 µg/mL. Compounds 5, 9, and 16 exhibited antituberculosis activity against Mycobacterium tuberculosis with MIC values of 50, 50, and 25 µg/mL, respectively.

Key words
