S-ethyl N-[4-(trifluoromethyl)phenyl] Isothiourea (hydrochloride) is a selective and competitive nNOS inhibitor with Ki value of 0.32 μM for the purified human enzyme [1].
Nitric oxide (NO) is an endogenously produced inorganic free radical gas which has been implicated in blood pressure homeostasis, platelet aggregation, neurotransmission, and immunological defense mechanisms. NO is synthesized by three isoforms of nitric oxide synthase (NOS): nNOS, eNOS and iNOS [1].
S-ethyl N-[4-(trifluoromethyl)phenyl] Isothiourea (hydrochloride) (EPIT) is a selective and competitive nNOS inhibitor. S-ethyl N-[4-(trifluoromethyl)phenyl] Isothiourea inhibited human nNOS, eNOS and iNOS with Ki values of 0.32 μM, 9.4 μM and 37 μM, respectively. EPIT exhibited 115-fold and 29-fold selectivity for nNOS compared to iNOS and eNOS, respectively [1].
In mice, EPIT administered intravenously at 25 mg/kg readily penetrated the blood-brain barrier, immediately reaching concentrations in the brain equal to the plasma concentration. In rat brain slices, EPIT failed to inhibit nNOS activity, possibly due to reduced intracellular uptake [1].

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
