Sitagliptin phosphate monohydrate is the phosphate salt of its active component, sitagliptin, with one molecule of water. Sitagliptin is a potent inhibitor of dipeptidyl peptidase 4 (DPP-4), an enzyme catalyzing the cleavage of peptides with an N-terminal alanine or proline amino acid residue, that selectively inhibits DPP-4 with 50% inhibition concentration IC50 value of 18 nM and shows no affinity towards other DDP enzymes (such as DDP-8 and DDP-9). The inhibition of DPP4 by sitagliptin has been found to be mediated by increasing levels of two DPP-4 substrates, including glucagon-like peptide-1 (GLP-1) and gastric inhibitory polypeptide (GIP). Sitagliptin is currently being investigated in the treatment of type II diabetes.

Reaction Conditions |
14 d; 25 μmol/L |
|
Applications |
To determine whether sitagliptin treatment participated in enhancing the differentiation of EPCs and MSCs and cells expressing its ligand, SDF-1α, adipose tissues were co-cultured with sitagliptin (25 μmol/L) in M199 culture medium for 14 d and examined by flow cytometric analysis. The results show that compared with the 7 d cell culture, the numbers of EPCs [CD31/Sca-1+(double-stained) and CXCR4+ (single-stained)] were remarkably higher at day 14 in both the non-sitagliptin-treated (Si-T) group and the Si-T group |

Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
