Some novel bicyclic thiazolopyrimidine derivatives bearing various substituents have been synthesized through one-pot three-component method. Structures of the target compounds were confirmed by elemental analysis and spectral data. Some selected members of the newly synthesized compounds were investigated for their analgesic and anti-inflammatory activities and revealed pronounced anti-inflammatory activity greater than that of indomethacin (reference drug).

In vitro antiproliferative activities of some pyrimido[4,5-e][1,3,4]oxadiazine and [1,2,4]triazolo[4',3':1,2]pyrimido[4,5-e][1,3,4]oxadiazine derivatives were examined in human malignant cancer cell lines. All synthesized compounds inhibited the growth of malignant cells in a dose dependent manner, but among them 1,5,7-trimethyl-3-phenyl-1H-[1,2,4]triazolo[4',3':1,2]pyrimido[4,5-e][1,3,4]oxadiazine and [(1,5-dimethyl-3-phenyl-1H-[1,2,4]triazolo[4',3':1,2]pyrimido[4,5-e][1,3,4]oxadiazin-7-yl)sulfanyl]acetonitrile, both with triazole moiety, were found to be more effective than other compounds; they also induced a sub-G1 peak in the flow cytometry histogram of treated cells compared to controls, indicating that apoptotic cell death is involved in toxicity they induce. The results showed that compounds with triazole moiety fused to pyrimido[4,5-e] [1,3,4]oxadiazine derivatives are more active than those bearing chlorine or pyrrolidine groups at C-7 position.

In frames of the search for new biological entities to fight against recent drug-resistant microbial strains, we report a library of quinazoline-based thiourea/4-thiazolidinone/chalcone hybrids. The newly synthesized compounds were studied for efficacy against several bacteria (Staphylococcus aureus, Bacillus cereus, Pseudomonas aeruginosa, and Klebsiella pneumoniae) and fungi (Candida albicans and Aspergillus clavatus) using the broth dilution technique. From the biological evaluation, (E)-3-(3,4-dimethoxyphenyl)-1-(4-((4-(4-ethylpiperazin-1-yl)quinazolin-2-yl)amino)phenyl)prop-2-en-1-one was found to be the most active analogue (microbial inhibition concentration 3.12 μg/mL) to inhibit the bacterial growth. The rest of the compounds showed equipotent efficacy (3.12-12.5 μg/mL) as compared to the standard. Final compounds were characterized by FT-IR, 1H NMR, 13C NMR, mass spectroscopy, and elemental analysis.

A new series of N-Aryl-2-(5H-[1,2,4]triazino[5,6-b]indol-3-ylsulfanyl)acetamides were synthesized by condensation of tricyclic compound 2,5-dihydro-3H-[1,2,4]triazino[5,6-b]indole-3-thione with chloro N-phenylacetamides. The tricyclic compound was obtained by condensation of Isatin with thiosemicarbazide. Chloro N-phenylacetamides were obtained from different substituted anilines. Their structures were characterized by IR, 1H NMR, LC-MS and elemental analyses. Newly synthesized compounds were screened for antimicrobial, antidepressant and anticonvulsant activities. Preliminary results indicated that most of the compounds showed lesser MIC value than the standard drug used when tested for antimicrobial activity. Some of the compounds were endowed with very good antidepressant and anticonvulsant activity.

A series of aralkanoic acids was converted into aralkanoic acid hydrazides through their esters formation. The aralkanoic acid hydrazides upon treatment with carbon disulfide and methanolic potassium hydroxide yielded potassium dithiocarbazinate salts, which on refluxing with aqueous hydrazine hydrate yielded 5-aralkyl-4-amino-3-mercapto-1,2,4-triazoles. The target compounds, 3-aralkyl-6-(substitutedquinolinyl)[1,2,4]triazolo[3,4-b][1,3,4]thiadiazoles, were synthesized by condensing various quinolinyl substituted carboxylic acids with 5-aralkyl-4-amino-3-mercapto-1,2,4-triazoles in phosphorus oxychloride. The structures of the newly synthesized triazolothiadiazoles were characterized by IR, 1H NMR, 13C NMR, and elemental analysis studies. The structure of one of the 5-aralkyl-4-amino-3-mercapto-1,2,4-triazoles was unambiguously deduced by single crystal X-ray diffraction analysis. All the synthesized compounds were screened for their acetylcholinesterase inhibition activities. Four of the triazolothiadiazoles exhibited excellent acetylcholinesterase inhibition activities as compared to the reference inhibitor.

Initially the acute toxicity of the compounds was assayed via the determination of their LD50. Some of the newly synthesized compounds exhibited better pharmacological and biological responses than the reference controls with low concentrations. The structures of newly synthesized compounds were confirmed by chemical, elemental and spectroscopic evidences.

Synthesis of sulfanylimines based on neomenthane and isobornane thiol was carried out with yields up to 85%. On the model of H2O2- and AAPH-induced hemolysis of blood erythrocytes it was found that the sulfenimines have membrane protective and antioxidant activities and inhibit the accumulation of secondary products of lipid peroxidation and oxidation of hemoglobin.
