A new series of amino acid derivatives of quinolines was synthesized through the hydrolysis of amino acid methyl esters of quinoline carboxamides with alkali hydroxide. The compounds were purified on silica gel by column chromatography and further characterized by TLC, NMR and ESI-TOF mass spectrometry. All compounds were screened for in vitro antimicrobial activity against different bacterial strains using the microdilution method. Most of the synthesized amino acid-quinolines show more potent or equipotent inhibitory action against the tested bacteria than their correspond esters. In addition, many of them exhibit fluorescent properties and could possibly be utilized as fluorophores. Molecular docking and simulation studies of the compounds at putative bacterial target enzymes suggest that the antimicrobial potency of these synthesized analogues could be due to enzyme inhibition via their favorable binding at the fluoroquinolone binding site at the GyrA subunit of DNA gyrase and/or the ParC subunit of topoisomerase-IV.

The acetylcholinesterase (AChE) reactivators (e.g., obidoxime, asoxime) became an essential part of organophosphorus (OP) poisoning treatment, together with atropine and diazepam. They are referred to as a causal treatment of OP poisoning, because they are able to split the OP moiety from AChE active site and thus renew its function. In this approach, fifteen novel AChE reactivators were determined. Their molecular design originated from former K-oxime compounds K048 and K074 with remaining oxime part of the molecule and modified part with heteroarenium moiety. The novel compounds were prepared, evaluated in vitro on human AChE (HssAChE) inhibited by tabun, paraoxon, methylparaoxon or DFP and compared to commercial HssAChE reactivators (pralidoxime, methoxime, trimedoxime, obidoxime, asoxime) or previously prepared compounds (K048, K074, K075, K203). Some of presented oxime reactivators showed promising ability to reactivate HssAChE comparable or higher than the used standards. The molecular modelling study was performed with one compound that presented the ability to reactivate GA-inhibited HssAChE. The SAR features concerning the heteroarenium part of the reactivator’s molecule are described.

Background. The addition of active metabolites (in particular, amino acids) to the molecule affects the physicochemical and prodrug properties of derivatives of indolocarbazoles. Using computed chemoinformatics, probability antitumor activity of amino-acid derivatives of glycosides of indolocarbazol (AADGI) is predicted with low probability of their cytotoxic activity in vitro. Based on these data, a study of these compounds in vivo is conducted. Objective: the assessment of AADGI as potential antitumor medications. Materials and methods. Research antitumor activity of AADGI was done using murine tumor models - cervical cancer CC-5. Investigated compounds were injected to mice СВА abdominally 5-times daily with interval of 24 h. Observation of animals were continued till their death. Antitumor effect of compounds was assessed by criteria of tumor growth inhibition and increase in life expectancy of mice comparing to control animals. Results. The optimal dose for these series of compounds was titrated and this dose is 100 mg/kg. Antitumor activity of AADGI was assessed on CC-5. Conclusions. Based on data received we suggest an extended study in vivo of antitumor qualities of selected 5 leader AADGI.

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.
