Inhibition of transforming growth factor β (TGF-β) type 1 receptor (ALK5) provides a feasible approach for the treatment of fibrotic diseases and malignant tumors. In this study, we designed and synthesized a new series of 4-(pyridin-4-oxy)-3-(3,3-difluorocyclobutyl)-pyrazole derivatives, and evaluated biologically as TGF-β type 1 receptor inhibitors. The most potent compound 15r inhibited the ALK5 enzyme and NIH3T3 cell viability with IC50 values of 44 and 42.5 nM, respectively. Compound 15r also displayed better oral plasma exposure and excellent bioavailability than LY-3200882, and in vivo inhibited 65.7% of the tumor growth in a CT26 xenograft mouse model.

By targeting the flap backbone of the BACE1 active site, we discovered 6-dimethylisoxazole-substituted biaryl aminothiazine 18 with 34-fold improved BACE1 inhibitory activity over the lead compound 1. The cocrystal structure of 18 bound to the active site indicated two hydrogen-bond interactions between the dimethylisoxazole and threonine 72 and glutamine 73 of the flap. Incorporation of the dimethylisoxazole substitution onto the related aminothiazine carboxamide series led to pyrazine-carboxamide 26 as a very potent BACE1 inhibitor (IC50 1 nM). This compound demonstrated robust brain Aβ reduction in rat dose-response studies. Thus, compound 26 may be useful in testing the amyloid hypothesis of Alzheimer's disease.

The photochemistry of 4-acylisoxazoles 4, 5, 13, 14, and 17 was investigated in an effort to clarify literature contradictions and anomalies and to provide a more detailed picture of the nature and number of intermediates involved in photoreactions of these systems.In contrast to a previous report on the photorearrangement of 14, both oxazoles expected from a 2H-azirine intermediate have been observed.Wavelength studies of 5 and the derived 2H-azirine 10 revealed evidence for the involvement of at least two distinct product-forming intermediates.The results of quantum yield and laser photolysis measurements for ketones 4, 14, and 17 have been interpreted in terms of rapid openings of triplet states to form diradical-like intermediates coupled with efficient reclosures (70-99percent).
