Description

KF38789 is a selective inhibitor of P-selectin-PSGL-1 binding. KF38789 inhibits the binding of U937 cells to immobilized P-selectin immunoglobulin G chimeric protein (P-selectin-Ig) with an IC50 value of 1.97 μM[1].

In Vitro

KF38789 inhibits P-selectin-induced superoxide production from human polymorphonuclear cells. Intravenously injected KF38789 significantly inhibits the thioglycollate (TG)-induced accumulation of leukocytes in the mouse peritoneal cavity[1].
KF38789 displays a concentration-dependent inhibition of U937 cell adhesion to immobilized P-selectin-Ig with an IC50 value of 1.97±0.74 μM[1].
KF38789 specifically inhibits P-selectin-dependent cell adhesion and the leukocyte recruitment in mouse peritonitis[1].
KF38789 (5 μM) significantly reduces closure of a 500-μm gap between confluent sheets of Human corneal epithelial (HCE)-T cells over an 8-hr period (by ∼40%)[2].
Corneal epithelial cell migration is reduced in the presence of KF38789 (5 μM) [2].

In Vivo

KF38789 can block P-selectin-mediated binding in vitro and leukocyte accumulation in vivo[1].
Intraperitoneal injection of the P-selectin inhibitor KF38789 (daily intraperitoneal injection of 10mg/kg for 12 days) significantly reduces mechanical allodynia in the facial carrageenan-injected mice[3].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
