XEN445 is a novel, highly selective and potent inhibitor of endothelial lipase(EL) with an IC 50 value of 0.237μM [1].

In vitro, XEN445 has been reported to selectively inhibit EL with IC50 values of 0.237μM, 20μM and 9.5μM for hEL, hLPL and hHL, respectively. In addition, XEN445 has been revealed to suppress EL in EL-transfected HEK cells with an IC50 value of 0.25μM which is very similar to that tested in cell-free assay. Besides, XEN445 has shown significantly high oral bioavailability and low clearance rates in C57BL6 mice. In vivo, XEN445 has been evidenced to increase plasma HDLc in wild-type mice. Moreover, XEN445 has exhibited the HDL-raising effect because of on-target inhibition by using the EL knockout mice [1].
