The cross-linked microbeads with average diameter of 106-300 μm, [poly(EGDMA-MATrp)], were obtained by copolymerization reaction N-methacryloyl-L-(+)-tryptophan methyl ester (MATrp) ethylene glycol dimethacrylate (EGDMA) and successfully applied as a heterogeneous catalyst in conjugate addition nitromethane to substituted 2-iminochromenes aqueous media. A variety 2-amino-4-(nitromethyl)-4H-chro...
Ring cleavage occurred when 1,2,4-triazino-1,2,4-triazines (3), (4) and (5) were treated with concentrated hydrochloric acid to yield N-substituted triazines (7) and (8). These confirm the given configuration assigned to the isomeric triazinotriazines. 6-Methyl-2-phenyl-7H-oxazolo [3,2-b][1,2,4]-triazin-7-one (9) underwent ring cleavage on treatment with sodium alkoxide to afford 3-alkoxy-1...
The hypothesis was tested that M2-selective antagonists partially utilize the allosteric site of muscarinic M2 receptors. The interactions of the allosteric agent W84 (hexane-1, 6-bis[dimethyl-3'-phthalimidopropyl-ammonium bromide]) were studied with the M2/M4-selective AF-DX 384 [(+/-)-5, 11-dihydro-11-([(2-(2-[(dipropylamino)methyl]-1-piperidinyl)ethyl)amino]carbonyl)-6H-pyrido(2,3-b)(1,4)-be...
As a part of ongoing studies in developing new anticancer agents, novel 1,2-dihydropyridine 4, thienopyridine 5, isoquinolines 6-20, acrylamide 21, thiazolidine 22, thiazoles 23-29 and thiophenes 33-35 bearing a biologically active quinoline nucleus were synthesized. The structure of newly synthesized compounds was confirmed on the basis of elemental analyses and spectral data. All the newly sy...
New trans- and cis-o-stilbene-methylene-sydnones 3a,b were synthesized by transforming the trans- and cis-o-aminomethylstilbene derivative, obtained by reduction of corresponding o-cyano derivatives, into glycine ester derivatives (43 and 31% yield) followed by hydrolysis (90 and 96% yield), nitrosation and ring closure with acetic acid anhydride (30 and 40% yield). The products were submitted ...
Compounds designed to display polypharmacology may have utility in treating complex diseases, where activity at multiple targets is required to produce a clinical effect. In particular, suitable compounds may be useful in treating neurodegenerative diseases by promoting neuronal survival in a synergistic manner via their multi-target activity at the adenosine A1 and A2A receptors (A1R and A2AR)...
