Paragraph 0023; 0025; 0030; 0034, (2020/08/18)
The invention relates to a synthesis method of 2-chloro-5-fluoro-6-methylpyrimidine, which comprises the following steps: dissolving sodium methoxide in methanol, adding urea, stirring, dropwisely adding ethyl 2-fluoroacetoacetate, and carrying out a reflux reaction for 2-3 hours to obtain an intermediate A; mixing the intermediate A, phosphorus oxychloride and organic alkali according to a weightratio of 1: (5-10): (0.3-2) for reaction, cooling the mixture, removing redundant phosphorus oxychloride, adding water for quenching extraction, drying, and concentrating to obtain a product B; and adding ethanol, zinc powder and acetic acid into the product B, carrying out a heating reflux reaction for 10-16 hours, cooling, filtering, evaporating to remove the ethanol, extracting with an organicsolvent, evaporating to dryness to obtain a crude product, and carrying out vacuum distillation to obtain a pure product C, namely the 2-chloro-5-fluoro-6-methylpyrimidine. The method has the effectsthat the yield is increased, the time is shortened, the operation is simple, and the post-treatment process is simplified.

Herein we describe structure-activity relationship (SAR) and metabolite identification (Met-ID) studies that provided insight into the origin of time-dependent inhibition (TDI) of cytochrome P450 3A4 (CYP3A4) by compound 1. Collectively, these efforts revealed that bioactivation of the fluoropyrimidine moiety of 1 led to reactive metabolite formation via oxidative defluorination and was responsible for the observed TDI. We discovered that substitution at both the 4- and 6-positions of the 5-fluoropyrimidine of 1 was necessary to ameliorate this TDI as exemplified by compound 19.

Activation of the G-protein coupled receptor (GPCR) Takeda G-protein receptor 5 (TGR5), also known as G-protein bile acid receptor 1 (GPBAR1), has been shown to play a key role in pathways associated with diabetes, metabolic syndrome, and autoimmune disease. Nipecotamide 5 was identified as an attractive starting point after a high-throughput screen (HTS) for receptor agonists. A comprehensive hit-to-lead effort culminated in the discovery of 45h as a potent, selective, and bioavailable TGR5 agonist to test in preclinical metabolic disease models. In genetically obese mice (ob/ob), 45h was as effective as a dipeptidyl peptidase-4 (DPP-4) inhibitor at reducing peak glucose levels in an acute oral glucose tolerance test (OGTT), but this effect was lost upon chronic dosing.
