Definitions
- the present invention relates to a novel bicyclooctane derivative, a process for producing the same, a pharmaceutical composition containing the same, and a therapeutic agent thereof In particular as a dipeptidyl peptidase inhibitor (DPPIV).
- DPPIV dipeptidyl peptidase inhibitor
- BACKGROUND OF THE INVENTION Diabetes is a multi-pathogenic metabolic disease characterized by chronic hyperglycemia accompanied by disorders of sugar, fat and protein metabolism caused by defects in insulin secretion and/or action. Diabetes is a very old disease. It is caused by the absolute or relative lack of insulin in the human body. The concentration of grape vines in the blood is increased, and then the sugar is discharged from the urine, and there are polydipsia, polyuria, polyphagia, and weight loss. Dizziness, fatigue and other symptoms.
- DPPIV Dipeptidyl Peptidase-IV
- a serine protease that cleaves N-terminal dipeptidase in a peptide chain containing a proline residue at the secondary end, although DPPIV has no physiological effects on mammals. It is fully confirmed, but it plays an important role in neuroenzyme metabolism, T-cell activation, cancer cell metastasis into the endothelium and HIV virus entry into lymphoid cells (W098/19998).
- DPPIV can block the secretion of glucagon-like peptide (GLP)-1, in particular, it can cleave the N-terminal group-propadipeptide enzyme in GLP-1 from the active form of GLP- 1 (7-36) NH 2 degraded to inactive GLP-1 (9-36) NH 2 (Endocrinology, 1999, 140: 5356 ⁇ 5363). Due to physiological conditions, the half-life of intact GLP-1 in circulating blood is very short, and the inactive metabolites after DPPIV degrades GLP-1 can bind to GLP-1 receptor antagonistic activity GLP-1, thereby shortening the physiology of GLP-1. reaction.
- DPPIV inhibitors can completely protect endogenous and even exogenous GLP-1 from being inactivated by DPPIV, greatly increasing the physiological activity of GLP-1 (5 to 10 times), due to the secretion of insulin from pancreas by GLP-1. It is an important buffer and can directly affect the distribution of glucose. DPPIV inhibitors play a very good role in the treatment of non-insulin-dependent diabetes mellitus (NIDDM) (US6110949).
