Biological Activity
| Targets | PPARγ |
| ln Vitro | AMG131 (INT131) exhibits a Ki of approximately 10 nM when binding to PPARγ, displacing Rosiglitazone. Its affinity is approximately 20 times greater than that of either Rosiglitazone or Pioglitazone, and it has a selectivity of more than 1000 times for PPARγ over PPARα, PPARδ, or a group of other nuclear receptors. With no binding to PPARα or δ at 10 μM, 1000 times over the Ki for PPARγ, AMG131 exhibits high selectivity for PPARγ[1]. |

| Animal Protocol |
Male Zucker fatty (fa/fa) rats ages 7-8 weeks[2] 80 mg/kg Administered once daily by oral gavage for 14 days |

| Additional Infomation |
AMG-131 (T131), an orally-administered therapy, is expected to lower blood glucose in type II diabetic patients by improving the body’s ability to respond to insulin. T131 is a selective modulator of PPARg (peroxisome proliferator activated receptor gamma), a receptor involved in regulating the body’s ability to respond to insulin. T131 is not structurally related to the thiazolidinedione class of PPARg agonists, which includes Actos and Avandia. Drug Indication Investigated for use/treatment in diabetes mellitus type 2. Mechanism of Action T131 is a selective modulator of PPARg (peroxisome proliferator activated receptor gamma), a receptor involved in regulating the body’s ability to respond to insulin.

Solubility Data
| Solubility (In Vitro) | DMSO: ~250 mg/mL (~486.2 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (4.05 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (4.05 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. (Please use freshly prepared in vivo formulations for optimal results.) |
