Synthesis of thiosulphonate and amino acid derivatives of benzochinone and predicted screening of their biological activity

Abstract

Quinoid derivatives are attractive not only as interesting synthons for synthesis, but also as potential biologically active substances, so it is important to modify the compounds of the quinone series with different pharmacoform fragments. In this work, the structural design of chlorine and bromanyl disulfur-containing fragments, namely thiosulfonate, and chloranyl – a fragment of 4- aminobutanoic acid. Methods of synthesis were developed and physicochemical characteristics of thiosulfonate and amino acid derivatives were studied: 2,5-bis (thiosulfonate) -3,6-halogen -1,4- benzoquinones and 2,5-bis (3-carboxypropylamino) -3,6 - dichlorobenzoquinone. The prospects for the design of chlorine and bromanyl thiosulfonate fragments and chloranyl fragment of 4- aminobutanoic acid are confirmed by the results of predicting the biological activity of 5 a, b, 6 a, b, 7 using the online resource PASS Online. In particular, the substance 6a obtained by us is promising in terms of research on Antiviral (Picornavirus). The obtained results of predicted cytotoxicity screening indicate the feasibility of conducting experimental studies by in vitro methods on anticancer activity against cancer cell lines of hematopoietic and lymphoid tissue, lungs, skin, ovaries, blood, breast, kidney, colon, brain.
