Biological target:
SR1555 is a RORγ inverse agonist with an IC50 value of 1 μM. SR1555 also increases the frequency of T regulatory cells, as well as inhibits the expression of IL-17.
In vitro activity:
Synthetic RORγ ligands, such as SR1555, could potentially be developed to target both suppression of T(H)17 and stimulation of T regulatory cells, offering key advantages in targeting autoimmune diseases. This study identified SR1555 as able to inhibit T(H)17 cell development and function and increases the frequency of T regulatory cells.

In vivo activity:
SR1555 may have potential in obesity treatment. Chronic administration of SR1555 to obese diabetic mice resulted in a modest reduction in food intake. There was also a significant reduction in fat mass, resulting in reduced body weight and improved insulin sensitivity. Ex vivo analysis demonstrated that SR1555 induced expression of the thermogenic gene program in fat depots.

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.
