A new class of small-molecule GnRH antagonists, the thieno[2,3-b]pyrroles, was designed. Herein, the synthesis and structure-activity relationships are described. Substitution at the C4 position was investigated; during this study, it was observed that introducing piperazines and piperidines improved the physical properties of the compounds while retaining(More)
Starting from potent inhibitors of PI3Kα having poor general kinase selectivity (e.g., 1 and 2), optimisation of this series led to the identification of 25, a potent inhibitor of PI3Kα (wild type, E545K and H1047R mutations) and PI3Kδ, selective versus PI3Kβ and PI3Kγ, with excellent general kinase selectivity. Compound 25 displayed low metabolic turnover(More)
We report the discovery of a novel aminopyrazine series of PI3Kα inhibitors, designed by hybridizing two known scaffolds of PI3K inhibitors. We describe the progress achieved from the first compounds plagued with poor general kinase selectivity to compounds showing high selectivity for PI3Kα over PI3Kβ and excellent general kinase selectivity. This effort(More)
The investigation of the SAR of 5-lipoxygenase (5-LO) inhibition of a series of racemic (methoxyalkyl)thiazoles, exemplified by compound 7 (ZM-211965), has led to other active, racemic derivatives in which the thiazole moiety has been replaced by an ester or an ether. Furthermore, the cyclization of the ethers has given a highly potent, but achiral series,(More)
