The invention relates to beta-amino tetrahydropyrazine, tetrahydropyrimidine and tetrahydropyridine used as dipeptidy peptidase inhibitors for curing or preventing diabetes. Each variable quantity is defined as the application specification. The compounds are the inhibitors of dipeptidy peptidase-IV enzyme ('DP-IV inhibitors') and can be used for curing or preventing diseases relevant to the dipeptidy peptidase-IV enzyme, such as the diabetes, particularly the II-type diabete. The invention also relates to a medicinal composition comprising the compounds and application of the compounds and the composition in preventing or curing the diseases relevant to the dipeptidy peptidase-IV enzyme.

The invention discloses a novel crystal form of oxalate of dipeptidyl peptidase inhibitor, namely, (s)-1-(2-(2-(3-(3,4-dimethoxyphenyl)-2-oxo-1-imidazolidinyl)ethylamino)acetyl)-2-cyanpyrrolidine oxalate. In X-ray powder diffraction of the crystal form, characteristic peaks occur at 2 theta diffraction angles of 4.5+/-0.1, 5.5+/-0.1, 9.0+/-0.1, 10.9+/-0.1, 16.4+/-0.1, 17.7+/-0.1, 18.1+/-0.1, 22.0+/-0.1, 22.7+/-0.1, 25.6+/-0.1, 28.1+/-0.1, 28.4+/-0.1 and 32.0+/-0.1. The crystal form disclosed by the invention is superior to the original oxalate in stability, and is more stable for light, heat and humidity and convenient to store and transport; the cost of the DPP-IV (dipeptidyl peptidase-IV) inhibitor in transportation and preservation processes is decreased; and the safety of the product is further guaranteed.

The present invention is directed to novel pharmaceutical compositions comprising fixed dose combinations of a dipeptidyl peptidase-4 inhibitor (DPP-4 inhibitor), or a pharmaceutically acceptable salt thereof, and simvastatin, or pharmaceutically acceptable salt thereof, methods of preparing such pharmaceutical compositions, and methods of treating Type 2 diabetes and hypercholesterolemia with such pharmaceutical compositions. In particular, the invention is directed to pharmaceutical compositions comprising fixed-dose combinations of sitagliptin phosphate and simvastatin.

The invention provides a drug for treating hepatocellular carcinoma. The drug comprises a glucagon-like peptide-1 receptor stimulant and/or a dipeptidyl peptidase 4 inhibitor. The invention further provides application of the glucagon-like peptide-1 receptor stimulant and/or dipeptidyl peptidase 4 inhibitor to preparation of a drug for preventing or treating hepatocellular carcinoma, to preparation of a drug for liver function recovery after liver transplantation, and to preparation of a drug for preventing liver cancer relapse after liver transplantation. The glucagon-like peptide-1 receptor stimulant and/or dipeptidyl peptidase 4 inhibitor generates a differential effect in a tissue specificity way, so as to inhibit cancer cell proliferation and promote cancer cell apoptosis, meanwhile, liver cells are protected against apoptosis, so that obesity-dependent liver cancer or non-dependent liver cancer can be treated or weakened.
