In the present study we describe the synthesis of a new series of 1,2,4-triazoles: [3-(arylmethyl)thio-5-aryl-4H-[1,2,4] triazol-4-y1]acetic acids 5a-g, [5-(arylmethyl)thio-3-aryl-1H-[1,2,4]triazol-1-y1]acetic acids 8a-d, and [3-(aryl-methyl) thio-5-aryl-1H-[1,2,4]triazol-1-y1] acetic acids 9a-d. These compounds were tested in binding assays to evaluate their ability as ligands for human ETA and ETB receptors stably expressed in CHO cells; some of the tested compounds showed affinity in the micromolar range.
