Chemical Properties
white to off-white powder
Uses
A selective inducible nitric oxide synthase (iNOS) inhibitor. A long-acting human iNOS inhibitor possessing an IC50 value of 2.0uM.
Description
1400W (214358-33-5) is a potent, tight-binding, slow inhibitor of inducible nitric oxide synthase (iNOS). Highly selective for iNOS3?(Ki?= 7 nM) over nNOS or eNOS (Ki‘s of 2 μM and 50 μM respectively).1?1400W is cell permeable and active?in vivo.2
General Description
A selective, cell-permeable, irreversible, slow, tight-binding inhibitor of inducible nitric oxide synthase (iNOS; Kd = 7 nM). Suitable for use in both in vitro and in vivo systems. Has a protective effect against cerebral ischemia by reducing ischemic lesion volumes. Exhibits greater than 5000- and 200-fold potency against human iNOS relative to eNOS and nNOS, respectively, and greater than 1000-fold potency against rat iNOS relative to eNOS.
Biochem/physiol Actions
