Abstract:
The aim of the present study was to determine the cytotoxic effects of a series of novel dehydroepiandrosterone derivatives containing triazole at the C16 position on human cancer cells. The cancer cells used in the present study were A549, Hela, HepG-2, BEL7402, MCF-7, and HCT116. Several of the synthesised compounds exhibited potent antiproliferative effects. The most promising compound was (E)-3-hydroxy-16-((1-(4-iodophenyl)-1H-1,2,3-triazole-4-yl)methylene)-10,13-dimet-hyl-1,3,4,7,8,9,10,11,12,13,15,16-dodecahydro-2H-cyclopenta[a]phenanthren-17(14)-one (compound 2n), which showed considerably high antiproliferative activity in the HepG-2 cell line, with an IC50 value of 9.10 µM, and considerably high activity against the MCF-7 cell line, with an IC50 value of 9.18 µM. Flow cytometry assays demonstrated that compound 2n exerted antiproliferative effects by arresting cells in the G2 phase of the cell cycle and inducing apoptosis.

01:15Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.
