N,N,N″-Trisubstituted guanidines (most of them N″-aryl-N-azacycloalkanecarboximidamides) are prepared in generally good yields by S-methylation of monosubstituted thioureas with methyl iodide in methanol or acetone and reaction of the resultant methyl carbamimidothioate hydroiodides with secondary amines in boiling tert-butyl alcohol or acetonitrile.

Several new fluorinated quinolinederivatives were synthesized and tested for their anti-inflammatory and ulcerogenic effect. A docking study on the COX-2 binding pocket was carried out for the target compounds to rationalize the possible selectivity of them against COX-2 enzyme. The most active compounds (3, 2, 7 and 11) were found to be superior to celecoxib as they were devoid of any ulcerogenic

3-arylamino-5-[2-(substituted imidazol-1-yl or benzimidazol-1-yl)ethyl]-1,2,4-triazole derivatives were synthesised by reacting 3-(substituted imidazol-1-yl)propionyl hydrazides, with S-methyl-N'-arylisothiouronium iodide salts. Their structures were elucidated by IR, 1H-NMR and mass spectroscopic data and elemental analyses results. Antimicrobialactivities of the compounds were observed against Staphylococcus
