NAPAP
NAPAP is a selective direct thrombin inhibitor. NAPAP rapidly binds to thrombin and inhibits its activity, and reduces LPS (HY-D1056)-induced brain inflammation and coagulation factor expression in vivo. NAPAP can be used in studies related to coagulation and neuroinflammation.

Biological Activity
The D-enantiomer of NAPAP is a highly selective, potent direct thrombin inhibitor with a Ki of 0.0021 μM for thrombin, fast binding kinetics, and weak activity against trypsin, factor Xa, and plasmin[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
NAPAP (0.75 mg/kg; intraperitoneal injection; single administration) significantly reduces the hippocampal expression of pro-inflammatory markers and coagulation factors induced by LPS (HY-D1056) in male C57BL/6 mice[2].
NAPAP (400-1300 mg/kg; intraperitoneal injection; single administration) induces dose-dependent mortality, hepatotoxicity, and hepatic covalent binding in male ddY mice, with an LD50 of 820 mg/kg in control animals, while LPS pretreatment attenuates these toxic effects in a dose-dependent manner[3].
