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.

A lot of peptides were synthesized on the basis of the sequence of αs1-casein. These tri-peptides with the characteristics of low toxicity and high biological activity will be applied to screen a new type of antihypertensive drug. Angiotensin-converting enzyme inhibitors (ACEI) with the better biological activity were screened and their structure-activity relationship was studied. The method of Fmoc solid-phase synthesis had been used to synthesize tri-peptides, and the principle, species, steps of which had been introduced respectively. HPLC assay was applied to screen the activity of ACEI by detecting the concentrate of hippuric acid, which can correspond with the inhibitory activity of tri-peptides. The results showed that the tri-peptides containing hydrophobic amino acid or praline had higher inhibition activity, and the same to the one that containing an aromatic amino acid in N-terminal.
