Anticytokinin activity of substituted pyrrolo[2,3-d]pyrimidines.

Ten substituted pyrrolo[2,3-d]pyrimidines were tested as cytokinins and anticytokinins in the tobacco bioassay. Eight new anticytokinins were identified and two were found to be highly active. The most potent species were 4-cyclohexylamino- and 4-cyclopentylamino-2-methylthiopyrrolo[2,3-d]pyrimidine, of which 0.05 and 0.009 muM concentrations, respectively, were required to produce detectable i...

Anticytokinin Activity of N-Phenyl- and N-Pyridylcarbamates

A new class o f non-adenylate anticytokinins, alkyl and phenyl N -phenylcarbam ates and re­ lated phenyl N-pyridylcarbam ates, has been developed. They have a structure that has an im ­ m ediate resem blance to the non-adenylate class o f cytokinins, N ,N '-diphenylureas, and N -pyridyl-N '-phenylureas, and the design o f the m olecule was m ade based on insight into the bioisoteric nature betw...

Synthesis and Study of Antitumor Activity of Substituted Imidazolecarboxamides

      In view of potential biological activities of small molecule polyamides, we synthesized some novel N-(2-aminoethyl)-1-benzyl-2- (alkylthio)-1H-imidazole-5-carboxamide (7a,b), and N-(2-(1-benzyl-2-(alkylthio) -1H-imidazole- 5-carboxamido) ethyl)-1-benzyl-2- (alkylthio)-1H-imidazole-5-carboxamides (8a,b) as antitumor agents. The antitumor activity of compounds 7a,b and 8a,b was studied at c...

In Vitro Antimicrobial Activity of New Substituted Phenylthiazole Derivatives

Background: In this study, we evaluated antibacterial and antifungle activity of these derivatives against gram positive (Staphylococcus aureus, Bacillus subtilis, B. cereus), gram negative (Proteus vulgaris) bacteria and fungale (Candida albicans, C. tropicalis and C. glabrata). Methods: The broth macro dilution and well agar diffusion methods were used for determination of inhibition zoom (I...

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
