Discovery of S3-Truncated, C-6 Heteroaryl Substituted Aminothiazine beta-Site APP Cleaving Enzyme-1 (BACE1) Inhibitors.
J.Med.Chem., 59:8593-8600, 2016

PubMed Abstract: Truncation of the S3 substituent of the biaryl aminothiazine 2, a potent BACE1 inhibitor, led to a low molecular weight aminothiazine 5 with moderate activity. Despite its moderate activity, compound 5 demonstrated significant brain Aβ reduction in rodents. The metabolic instability of 5 was overcome by the replacement of the 6-dimethylisoxazole, a metabolic soft spot, with a pyrimidine ring. Thus, truncation of the S3 substituent represents a viable approach to the discovery of orally bioavailable, brain-penetrant BACE1 inhibitors.
