Abstract: A high throughput screening campaign revealed compound 1 as a potent antagonist of the human CCK1 receptor. Here, we report the syntheses and SAR studies of 1,5-diarylpyrazole analogs with various structural modifications of the alkane side chain of the molecule. The difference in affinity between the two enantiomers for the CCK1 receptor and the flexible nature of the linker led to the design of constrained analogs with increased potency.

Abstract: High throughput screening revealed compound 1 as a potent antagonist of the CCK1 receptor. Evaluation of the CCK1 SAR in a series of these diarylpyrazole antagonists was conducted in a matrix synthesis format revealing additive (Free–Wilson) and non-additive SAR. This use of additive QSAR modeling in conjunction with combinatorial libraries represents a unique approach to the evaluation of SAR interactions between the variables of any combinatorial matrix.

Abstract: High-throughput screening revealed compound 1 as a potent antagonist of the CCK1 receptor. Here, we disclose the synthesis of combinatorial libraries by solid-phase synthesis on Kenner ‘safety catch’ resin. Additive QSAR models were used to determine a lack of consistent additive SAR within the matrix. [Copyright &y& Elsevier]

Abstract: A series of CCK2R-selective anthranilic amides is shown to derive CCK1R affinity via selective substitution of the amide side chain. Thus, extending the length of the original benzamide side chain by a single methylene unit imparts CCK1R affinity to the series, and further fine tuning of the affinity results in CCK1R selectivity of greater than 100-fold.

Abstract: In the previous article we demonstrated how certain CCK2R-selective anthranilic amides could be structurally modified to afford high-affinity, selective CCK1R activity. We now describe our efforts at modulating and optimizing the CCK1R and CCK2R affinities aimed at producing compounds with good pharmacokinetics properties and in vivo efficacy in rat models of gastric acid and pancreatic amylase secretion.
