The discovery, synthesis, and preliminary structure-activity relationship (SAR) of a novel class of vasopressin V3 (V1b) receptor antagonists is described. Compound 1, identified by high throughput screening of a diverse, three million-member compound collection, prepared using ECLiPS (TM) technology, had good activity in a V3 binding assay (IC(50) = 0.20 mu M), but less than desirable physicochemical properties. Optimization of compound 1 yielded potent analogs 19 (IC(50) = 0.31 mu M) and 24 (IC(50) = 0.12 mu M) with improved drug-like characteristics. (c) 2010 Elsevier Ltd. All rights reserved.
