gs 9674

Taminadenant, also known as PBF-509 and NIR-178, is a potent and orally active adenosine A2A receptor antagonist with potential antineoplastic activity. PBF-509 selectively binds to and inhibits A2AR expressed on T lymphocytes. This abrogates the adenosine A2AR-mediated inhibition of T-lymphocytes and activates a T-cell-mediated immune response against tumor cells, thereby reducing proliferation of susceptible tumor cells. A2AR, a G protein-coupled receptor, is highly expressed on the cell surfaces of T-cells and, upon activation by adenosine, inhibits their proliferation and activation. Adenosine is often produced in excess by cancer cells.

Cilofexor 是一种法尼醇 X 受体激动剂，EC50为 43 nM。它抑制合成肽的结合，具有抗炎和抗纤维化作用。它可用于原发性硬化性胆管炎和非酒精性脂肪性肝炎的研究。

Cilofexor, also known as GS-9674, is a farnesoid X receptor (FXR) agonist. The nonsteroidal FXR agonist cilofexor (GS-9674) improves markers of cholestasis and liver injury in patients with PSC. In clinical study, cilofexor was well tolerated and led to significant improvements in liver biochemistries and markers of cholestasis in patients with PSC.
