Abstract

The research aims to synthesize 2-(3,4-dichlorophenyl)-4H-benzo[d][1,3]oxazin-4-one and evaluate its anticancer activity against MCF-7. This compound was selected based on in-silico study conducted against several dihalophenylbenzoxazinone analogues using molecular docking towards Methionyl-tRNA synthetase. Synthesis of target compound was carried out using anthranilic acid and 3,4-dichlorobenzoyl chloride. The resulting compound was characterized using various spectroscopic analysis: 1D and 2D NMR, infrared and MS. In-silico studies was performed by MVD. Several designed compounds were docked into the active site on Methionyl-tRNA Synthetase (1PG2). Anticancer activity was evaluated by MTT Assay against MCF-7. 2-(3,4-dichlorophenyl)-4H-benzo[d][1,3]oxazin-4-one has been successfully synthesized with decent amount of yield 88 %. Its spectroscopic analysis 1D and 2D NMR, MS, FTIR has proven the chemical structure of compound. In-silico studies toward the enzyme showed docking score of - 76.04 Kcal/mol, higher than its native ligand (-93.50 Kcal/mol). Meanwhile, MTT assay result against MCF-7 showed IC50 value of 68.59ppm. Based on preliminary in-silico studies inhibited Methionyl-tRNA Synthetase, 2-(3,4-dichlorophenyl)-4H-benzo[d][1,3]oxazin-4-one was synthesized and tested in-vitro against MCF-7. Albeit the compound does not possess better docking score than native ligand, it is still argued that benzoxazine ring can be considered as a potential anticancer agent, as showed by MTT assay result which indicated moderate cytotoxicity.
