Abstract

Hyptolide was isolated from the leaves of Hyptis pectinata (L.) Poit and was studied in order to discover and develop an anticancer drug. Hyptolide was obtained as a crystal of 87°C–88°C melting point. Spectroscopic identification results show a wave number at 1,735 cm−1 indicating the presence of α,β-unsaturated δ-lactone. Gas chromatography-mass spectrometry (GC-MS) analysis provides a single peak in the retention time of 11.701 by m/z value at 239, which indicates explicitly hyptolide. The objective of this research was to evaluate the hyptolide’s mechanism of cytotoxic on MCF-7 human breast cancer cells in positive estrogen receptor. The assay test to 3-(4,5-dimethylthiazol-2-yl)-2,5- dphenyl tetrazolium bromide (MTT) showed that hyptolide exhibited cytotoxic effects on MCF-7 and T47D breast cancer cells with an IC50 value of 76.76 and 181.55 µg/ml, respectively. Interestingly, the treatment of hyptolide for 24, 48, and 72 hours decreased cell viability on MCF-7 with dose- and time-dependent manner compared to untreated cells. Results of acridine orange-ethidium bromide multiple staining assay revealed that hyptolide induced apoptosis in a dose�dependent manner. It can be concluded that hyptolide possesses antiproliferative effects through apoptosis induction
