We synthesized two series (7a-i and 8a-i) of 2,3,5-substituted [1,2,4]-thiadiazole analogues of SCH-202676 (7a, 2,3-diphenyl-5-N-methylimino- 2H-[1,2,4]-thiadiazole) with emphasis on the N-imino substituent. Compounds 7a-g,i and 8a-g at a final concentrat

A number of 2,3,5-substituted [1,2,4]thiadiazole analogues of SCH-202676 (N-(2,3-diphenyl-[1,2,4]thiadiazole-5(2H)-ylidene)methanamine, 7a) were synthesized and tested as potential allosteric modulators of adenosine receptors. All compounds were capable of displacing the binding of the radiolabeled agonist [3H]CCPA to human A1 adenosine receptors, whereas modest and varying effects were observed on the binding of [3H]DPCPX, a radiolabeled antagonist for this receptor subtype. Four compounds, 7a (SCH-202676), 7k (LUF5792), 71 (LUF5794), and 8e (LUF5789), were selected for more detailed characterization. They all proved allosteric inhibitors of agonist binding, with 7k being most potent, whereas their effects on antagonist binding were more ambiguous. Subsequently, experiments were done on human adenosine A2A and A3 receptors. Compounds 7a and 7l displayed peculiar displacement characteristics of both radiolabeled agonist and antagonist binding to A2A receptors, whereas 7a showed some activity on A3 receptors.

1,2,4-Thiadiazol-5(2H)-imines 4 react with N-(2,2,2-trichloroethylidene)-substituted amides 5 to form [3 + 2]-cycloaddition products 6 featured by an extra coordination of the ring sulfur atom to the terminal nitrogen atom of the side 1,3-diazapropenylide

The chlornation of 1-(N-arylbenzimidoyl)thioureas under mild conditions leads to the formation of 5-amino-2-aryl-3-phenyl-1,2,4-thiadiazoluim chlorides, which are acylated at the exocyclic nitrogen atom when heated with carboxylic acid anhydrides or chlor
