Abstract

The synthesis and preliminary structure–activity relationships (SAR) of a novel class of vasopressin V1B receptor antagonists are described. Hit compound 5, identified via high throughput screening of the corporate collection, showed good activity in a V1B binding assay (Ki 63 nM) but did not possess the lead-like physicochemical properties typically required in a hit compound. A ‘deletion approach’ on the HTS hit 5 was performed, with the focus on improvement of physicochemical properties, yielding the selective V1B antagonist 9f (Ki 190 nM), with improved druglike characteristics.
