SB756050 is a novel, potent and selective TGR5 agonist which is currently under investigation in phase 1 clinical trials for the treatment of type 2 diabetes. TGR5 is a bile acid receptor and a potential target for the treatment of type 2 diabetes (T2D). In a phase 1 study, the safety, pharmacokinetics, and pharmacodynamic effects of SB-756050 was evaluated in patients with T2D. Fifty-one subjects were randomized to receive either placebo or one of four doses of SB-756050 for 6 days. A single 100 mg dose of sitagliptin was co-administered on Day 6 to all subjects. SB-756050 was well-tolerated; it was readily absorbed, exhibited nonlinear pharmacokinetics with a less than dose-proportional increase in plasma exposure above 100 mg, and demonstrated no significant changes in exposure when co-administered with sitagliptin. SB-756050 demonstrated highly variable pharmacodynamic effects both within dose groups and between doses, with increases in glucose seen at the two lowest doses and no reduction in glucose seen at the two highest doses. The glucose effects of SB-756050 + sitagliptin were comparable to those of sitagliptin alone, even though gut hormone plasma profiles were different. This study was registered at ClinicalTrials.gov (NCT00733577).

Biological Activity
| ln Vitro | One possible target for the therapy of type 2 diabetes (T2D) is the bile acid receptor TGR5 [1]. |
| ln Vivo | The drug SB756050 was well-tolerated; when combined with sitagliptin, it did not significantly alter exposure and showed nonlinear pharmacokinetics, with less than dose-proportional increases in plasma exposure above 100 mg. Between and between dose groups, SB756050's pharmacodynamic effects were remarkably inconsistent, with the two lowest doses causing an increase in glucose and the two highest doses causing no decrease in glucose. SB 756050 Despite having a distinct intestinal hormone plasma profile, sitagliptin's effects on glucose are similar to those of sitagliptin alone [1]. |

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples. Injection Formulations (e.g. IP/IV/IM/SC) Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution.
