nNOS-IN-3 (compound 4) is an orally active, selective, neuronal nitric oxide synthase (nNOS) inhibitor with a human hnNOS Ki of 25 nM, rat rnNOS Ki of 18 nM, human heNOS Ki of 58140 nM, human hiNOS Ki of 6422 nM. nNOS-IN-3 binds to nNOS active sites via hydrogen bonds with Glu and chalcogen bonds with Met, fails to form chalcogen bonds with heNOS, and undergoes passive transcellular transport with minimal efflux liability. nNOS-IN-3 can be used for the research of neurodegenerative diseases and melanoma.

Description

nNOS-IN-3 (compound 4) is an orally active, selective, neuronal nitric oxide synthase (nNOS) inhibitor with a human hnNOS Ki of 25 nM, rat rnNOS Ki of 18 nM, human heNOS Ki of 58140 nM, human hiNOS Ki of 6422 nM. nNOS-IN-3 binds to nNOS active sites via hydrogen bonds with Glu and chalcogen bonds with Met, fails to form chalcogen bonds with heNOS, and undergoes passive transcellular transport with minimal efflux liability. nNOS-IN-3 can be used for the research of neurodegenerative diseases and melanoma[1].

In Vitro

nNOS-IN-3 (compound 4) potently inhibits human nNOS with a Ki of 25 nM, and shows 2335-fold selectivity over human eNOS and 256-fold selectivity over human iNOS; it also inhibits rat nNOS with a Ki of 18 nM[1].
nNOS-IN-3 (200 μM; 17 h) exhibits favorable blood-brain barrier permeability in the PAMPA-BBB assay with an effective permeability of 16.67×10-6 cm/s, qualifying it as CNS-permeant[1].
nNOS-IN-3 shows high passive transcellular permeability in the Caco-2 assay, with an efflux ratio of 0.87 indicating minimal active efflux liability, supporting efficient intestinal absorption and blood-brain barrier penetration[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.
