Abstract

The invention belongs to the field of chemistry and medicine, in particular to a phenyl pyrimidine derivative and a preparation method and use thereof. The phenyl pyrimidine derivative as a specific GPR119 inhibitor provides a new choice for preventing and treating the metabolic disorders associated with type 2 diabetes mellitus, adiposis, lipid metabolism disorder and the like. The structure of the phenyl pyrimidine derivative is shown as the formula I.

Description

technical field [0001] The invention relates to a phenylpyrimidine derivative and its preparation method and use. Background technique [0002] Diabetes is multifactorial and is characterized by elevated plasma glucose levels (hyperglycemia) in the fasted state or after administration of glucose during an oral glucose tolerance test. There are generally two recognized forms of diabetes, In type 1 diabetes, or insulin-dependent diabetes mellitus (IDDM), the patient produces little or no insulin, the hormone used to regulate glucose. In type 2 diabetes, or non-insulin-dependent diabetes (NIDDM), the body still produces insulin. Patients with type 2 diabetes are resistant to the action of insulin to stimulate insulin and lipid metabolism in the main insulin-sensitive tissues (muscle, liver and adipose tissue). These patients usually have normal levels of insulin and may have hyperinsulinemia (elevated plasma insulin levels) as they compensate for the lowering effects of insul...
