PD 144795
PD 144795 is an orally active inhibitor of E-selectin (E-selectin), ICAM-1, and VCAM-1, with IC50 values of 6.6 μM, 4.0-10 μM, and 4.0 μM for the human targets, respectively. PD 144795 has favorable pharmacokinetic properties, including good absorption and no endothelial cytotoxicity. PD 144795 inhibits TNF-α-induced adhesion of neutrophils and monocytes to endothelial cells, reduces neutrophil infiltration, exudate accumulation, and footpad swelling, and delays disease progression in rodent models. PD 144795 can be used for inflammation-related research.

In Vitro
PD 144795 (pretreatment for 30 minutes + incubation for 4 hours) inhibits TNF-α-induced expression of ICAM-1 and E-selectin on the surface of human umbilical vein endothelial cells, with IC50 values of 4.0 μM and 6.6 μM, respectively[1].
PD 144795 (overnight treatment) inhibits the adhesion of U937 monocytes to human aortic endothelial cells under TNF-α stimulation, with an IC50 of 8.8 μM[1].
PD 144795 (incubated for 18 h) inhibits TNF-α-induced expression of VCAM-1 and ICAM-1 on the surface of human aortic endothelial cells, with IC50 values of 4.0 μM and 10 μM, respectively[1].
PD 144795 modulates the expression of TNF-α-responsive genes in human umbilical vein endothelial cells and human aortic endothelial cells without inhibiting NF-κB activation[1].
