Abstract
The purpose of this work was to prepare new isatin- and monothiomalondiamide-based indole derivatives, as well as to study the properties of the new compounds. The four-component reaction of 5-R-isatins (R = H, CH3), malononitrile, monothiomalonamide (3-amino-3-thioxo- propanamide) and triethylamine in hot EtOH yields a mixture of isomeric triethylammonium 6′-amino-3′-(aminocarbonyl)-5′-cyano-2-oxo-1,2-dihydro-1′H- and 6′-amino-3′-(aminocarbonyl)- 5′-cyano-2-oxo-1,2-dihydro-3′H-spiro[indole-3,4′-pyridine]-2′-thiolates. The reactivity and structure of the products was studied. We found that oxidation of spiro[indole-3,4′-pyridine]-2′-thiolates with DMSO-HCl system produced only acidification products, diastereomeric 6′-amino-5′-cyano-5-methyl-2-oxo-2′-thioxo-1,2,2′,3′-tetrahydro-1′H-spiro-[indole-3,4′-pyridine]- 3′-carboxamides, instead of the expected isothiazolopyridines. The alkylation of the prepared spiro[indole-3,4′-pyridine]-2′-thiolates upon treatment with N-aryl α-chloroacetamides and α-bromoacetophenones proceeds in a regioselective way at the sulfur atom. In the case of α-bromoacetophenones, ring-chain tautomerism was observed for the S-alkylation products. According to NMR data, the compounds consist of a mixture of stereoisomers of 2′-amino-6′-[(2-aryl-2-oxoethyl)thio]-3′-cyano-2-oxo-1′H-spiro[indoline-3,4′-pyridine]-5′-carboxamides and 5′-amino-3′-aryl-6′-cyano-3′-hydroxy-2-oxo-2′,3′-dihydrospiro[indoline-3,7′-thiazolo[3,2-a]pyridine]-8′-carboxamides in various ratios. The structure of the synthesized compounds was confirmed by IR spectroscopy, HRMS, 1H and 13C DEPTQ NMR studies and the results of 2D NMR experiments (1H-13C HSQC, 1H-13C HMBC). Molecular docking studies were performed to investigate suitable binding modes of some new compounds with respect to the transcriptional regulator protein PqsR of Pseudomonas aeruginosa. The docking studies revealed that the compounds have affinity for the bacterial regulator protein PqsR of Pseudomonas aeruginosa with a binding energy in the range of −5.8 to −8.2 kcal/mol. In addition, one of the new compounds, 2′-amino-3′-cyano-5-methyl-2-oxo-6′-{[2-oxo-2-(p-tolylamino)ethyl]thio}-1′H-spiro-[indoline-3,4′-pyridine]-5′-carboxamide, showed in vitro moderate antibacterial effect against Pseudomonas aeruginosa and good antioxidant properties in a test with 1,1-diphenyl-2-picrylhydrazyl radical. Finally, three of the new compounds were recognized as moderately active herbicide safeners with respect to herbicide 2,4-D in the laboratory experiments on sunflower seedlings.

Abstract
Noncatalyzed, regio- and stereoselective hypochlorite oxidation of 3-aminothieno[2,3-b]pyridine-2-carboxamides is presented. Unexpectedly, the oxidation proceeded by different mechanistic pathways, and different products were formed, depending on the nature of solvents used. A possible mechanism, the structure of products, kinetics and dynamics of intramolecular processes, and biological activity of products are discussed.

Abstract
Introduction: Due to widespread inflammatory processes, often accompanied by pain and fever syndromes, NSAIDs are now the most prescribed drug group in the world. NSAIDs are characterized by taking a leading position in the number and severity of adverse actions. In recent decades, the efforts of scientists have been aimed at seaching for adequate ways to increase the safety profile of NSAIDs.
Materials and methods: In a series of experiments, the main objects of research were derivatives of α-cyanothioacetamide – new tetrahydropyridones under laboratory codes TD 0364, TD 0353, TD 0351, CV 036, as well as hexahydroquinolines CV 125 and OCO 5184. One promising area for searching for effective and safe pharmacological agents is some derivatives of α-cyanothioacetamide (CAS Number: 7357-70-2). The trigeminal orofacial pain test and the thermal tail immersion test were used to assess the analgesic effect. Determination of antipyretic activity was carried out on the yeast-fever model. To study an anti-inflammatory activity, the method of subacute non-infectious parotitis was used.
Results and discussion: The results of the experiment made it possible to find among the new samples of tetrahydropyridones and hexahydroquinolines the compounds with analgesic, anti-inflammatory and antipyretic activities, which, in terms of these types of activities in dynamics, surpass the reference (paracetamol, diclofenac sodium, and ketorolac). It is important that these compounds have low acute toxicity.
Conclusion: The consequence of the above is the necessity of further preclinical and clinical studies of samples of α-cyanothioacetamide derivatives in order to create new promising highly effective and safe drugs with analgesic, anti-inflammatory and antipyretic activities.
