Parthenin, a medicinally important natural sesquiterpenoid and a potent allelochemical underwent different regio- and stereoselective modifications to several interesting analogues by chemical and biochemical means. The compound was treated with various common reducing agents including NaBH4, , , and as well as with different oxidizing agents including m-CPBA and dilute HCl under different reaction
Analogues of parthenin were synthesized by substitutions at different reaction centres to establish a structure-activity relationship (SAR). Some of the molecules have displayed significant cytotoxicity in human cervical carcinoma (HeLa) and human myeloid leukemia (HL-60) cells. A few of the compounds also induced apoptosis in HL-60 cells measured in terms of sub-Go/G1 DNA fraction. Also one of the lead molecules has been shown to be the inhibitor of both telomerase and topoisomerase-II. (C) 2009 Elsevier Ltd. All rights reserved.
