A new aromadendrane sesquiterpene was isolated from Chisocheton penduliflorus (Meliaceae) and compound 6 was moderately active against a small-cell lung cancer cell line and displayed antimycobacterial activity against Mycobacterium tuberculosis.
In vitro antimalarial activity of prenylated flavonoids from Erythrina fusca
Ethyl acetate extract from the stem bark of Erythrina fusca showed a antimalarial activity against the multi-drug-resistant strain (K1) of Plasmodium falciparum, and six flavonoids, lupinifolin, citflavanone, erythrisenegalone, lonchocarpol A, and 8-prenyldaidzein were isolated from the extract.

The structure of pyramidatine, a new bisamide alkaloid from leaves of Aglaia pyramidata, was determined through extensive nmr studies, including homonuclear COSY, NOESY, APT, HETCOR, and selective INEPT techniques, and piriferine was found to inhibit the growth of the vinblastine-resistant KB cells by enhancing the anticancer activity of vin Blastine.

A novel 3″,4″-dihydroglabridin was successfully prepared for studying on tyrosinase inhibitory activity and exhibited higher activity than glabridin, probably due to the 4-substituted resorcinol skeleton and the lacking of double bond between carbon atom 3″ and 4″ on its structure giving more conformational flexibily to interact with the enzyme more effectively.
