    Opis:
    A library of quinoline analog two novel series of azetidin (SH1-5) and thiazolidin (SHa-e) derivatives were designed and synthesized with simple and eco-friendly methodologies. The structures of the compounds were elucidated with the aid of elemental analysis, IR, 1H-NMR and mass spectral data. These novel synthesized compounds were evaluated for antibacterial activity against two gram-positive bacteria (Staphylococcus aureus, Staphylococcus pyogenus) and two gram-negative bacteria (Pseudomonas aeruginosa, Escherichia coli). The title compounds were also studied for their antifungal activity with Candida albicans, Aspergillus niger, Aspergillus clavatus using the broth dilution technique. Most of the compounds were the best bio-active desired antibacterial analog with less MIC value against different tested strains.

    Opis:
    A highly functionalized heterocyclic library were synthesized, and characterized by common spectroscopic methods. This novel synthetic rout involves nucleophilic substitution reaction of 3-cyano-4chloro coumarin with 4-(4-aminophenyl)morpholin-3-one in the presence of base and methanol as a solvent in good yield and high purity. Key starting material 4-(4-aminophenyl)morpholin-3-one synthesized from aniline. The reaction of aniline with ethylene oxide gives INT-1 which on reaction with Chloroacetyl chloride yield INT-b. Nitration of INT-b gives INT-c, which on reduction with Sn/HCl gives int-D. Further INT-3 was synthesized from 4-hydroxy coumarin. The Vilsmeier-haack reaction of 4-hydroxy coumarin gives INT-01 which on reaction with hydroxylamine hydrochloride and sodium acetate furnished INT-03. All the synthesized compound of libraries characterized using 1H NMR, Mass, and IR spectroscopic technique.

    Opis:
    A modular three step synthetic approach of N-methyl indole derivatives has been carried out by the condensation of N-methyl indole with cyanoacetic acid using acetic anhydride as solvent to yield 3-cyanoacetyl N-methyl indole, which further reacts with carbon disulphide and methyl iodide in basic condition to obtain 2-(1-methyl-1H-indole-3-carbonyl)-3,3-bis(methylthio)acrylonitrile as a scaffold. Subsequent, the scaffold when reacts with substituted various amine derivatives via desulfitative displacement forms new derivatives of 3-((substitutedphenyl)amino)-2-(1-methyl-1H-indole-3-carbonyl)-3-(methylthio)acrylonitrile in moderate to good yields. All the novel compounds were evaluated for their antimicrobial activity against Gram+ve and Gram-ve bacteria and different fungal species which demonstrated well to moderate antimicrobial activity.

    Opis:
    Some new tetrahydropyrimidine derivatives have been synthesized and their structural determination was done by IR, NMR and mass spectral data. Thermal analysis of these synthesized dihydropyrimidinthiones has been carried out by TGA and DSC techniques. From the thermograms, various kinetic parameters such as order of degradation (n), energy of activation (E), frequency factor (A) and entropy change (ΔS) have been evaluated. Further, thermal stability of tetrahydropyrimidine have been determined which is found to depend on the type of substituent present in the compounds.
