Description

nNOS-IN-6 is a human neuronal nitric oxide synthase (hnNOS) inhibitor with a human hnNOS Ki of 16 nM, ~1800-fold selectivity over human eNOS, ~2900-fold selectivity over human iNOS, and a rat nNOS Ki of 34 nM.nNOS-IN-6 exhibits high effective permeability in PAMPA-BBB assays, crosses the blood-brain barrier, and shows sustained systemic exposure, low clearance, and robust brain penetration in mouse in vivo pharmacokinetic studies.nNOS-IN-6 can be used for the research of neurodegenerative diseases, melanoma[1].

IC50 & Target

nNOS

16 nM (Ki)

In Vitro

nNOS-IN-6 (compound 16) potently inhibits human neuronal nitric oxide synthase (hnNOS) with a Ki of 16 nM, and exhibits approximately 1800-fold selectivity over human endothelial nitric oxide synthase (heNOS) and approximately 2900-fold selectivity over human inducible nitric oxide synthase (hiNOS)[1].
nNOS-IN-6 (200 μM; 17 h) exhibits high effective permeability (13.04×10-6 cm/s) in the PAMPA-BBB assay, demonstrating potent central nervous system penetration potential[1].

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.
