Abstract
Abstract The compounds 7-chloro-9-(2-hydroxy-4,4-dimethyl-6-oxocyclohex-1-en-1-yl)-3,3-dimethyl-2,3,4,9-tetrahydro-1H-xanthen-1-one (5) and 5-[-7-chloro-2,4-dioxo-1H, 2H, 3H, 4H, 5H-chromeno[2,3-d]pyrimidin-5-yl)]-1,3-diazinane-2,4,6-trione (7), were synthesized from dimedone and barbituric acid and had their three-dimensional structures and precise chemical shifts assignments obtained by Nuclear Magnetic Resonance (NMR) from 1H, 13C, APT, COSY, HSQC, and HMBC spectra. Additional HOMO-LUMO DFT calculations corroborated the NMR results and pointed to the most stable stereoisomers of each compound. Besides, further docking and molecular dynamic studies suggest that the stereoisomers (9S)-7-chloro-9-(2-hydroxy-4,4-dimethyl-6-oxocyclohex-1-en-1-yl)-3,3-dimethyl-2,3,4,9-tetrahydro-1H-xanthen-1-one, and 5-[(5S)-7-chloro-2,4-dioxo-1H, 2H, 3H, 4H, 5H-chromeno[2,3-d]pyrimidin-5-yl)]-1,3-diazinane-2,4,6-trione of these compounds may act as DNA intercalators and qualify as potential leads for the development of new anticancer drugs.
