ARL 17477
Based on 1 publication(s) in Google Scholar
ARL 17477 is a blood-brain barrier-penetrant selective neuronal nitric oxide synthase (nNOS) inhibitor with an IC50 of 1 μM. ARL 17477 reduces nitric oxide production and activates TFEB and lysosomal biogenesis, induces lysosomal membrane permeabilization, but inhibits autophagy-lysosomal function, autophagic flux, protein aggregate clearance, and proliferation. ARL 17477 induces ERK hyperphosphorylation and slight AKT inhibition. ARL 17477 exhibits NOS1 -independent anticancer activity against multiple cancer cells. ARL 17477 inhibits xenograft tumor growth in vivo. ARL 17477 can be used in research on colon cancer, non-small cell lung cancer, osteosarcoma, pancreatic cancer, arterial occlusion, and pain.

In Vitro
ARL 17477 (2 days) inhibits the viability of SW48, U251-MG, HCT116, A549, 143B, MIA PaCa-2, and NOS1-/- U251-MG cells, with IC50 values of 4.3-15.0 µM in the parental cell lines[2].
ARL 17477 (7 days) inhibits TGS-01 glioblastoma CSC tumorsphere formation with an IC50 of 4.4 µM[2].
ARL 17477 (2 days) inhibits 143B-sph osteosarcoma CSC viability with an IC50 of 1.1 µM[2].
ARL 17477 (5-25 µM; 1 day) increases LC3B-II and p62, hyperphosphorylates ERK, and decreases full-length PARP without inducing caspase-3/PARP cleavage in U251-MG cells[2].
ARL 17477 (25 µM; 48 h) activates lysosomal/TFEB and lipid synthesis gene programs in Panc-1 cells and suppresses the proliferation gene set[2].
ARL 17477-induced intracellular accumulation of autophagy markers depends on impaired lysosomal acidification[2].
ARL 17477 (1 µM; 30 min) inhibits lysosomal staining in MIA PaCa-2 cells[2].
ARL 17477 (6 days) impairs protein aggregate clearance and increases aggregates in MIA PaCa-2 cells[2].
ARL 17477 (100 µM; 1 h) induces lysosomal membrane permeabilization and increases cytosolic delivery in MIA PaCa-2 NanoBiT cells[2].
ARL 17477 (60 min) is a selective inhibitor of recombinant human nNOS in the [3H]arginine to [3H]citrulline conversion assay (IC50 = 1 μM), with weaker selectivity for eNOS (IC50 = 17 μM)[1].
ARL 17477 inhibits nNOS and endothelial NOS[3].

In Vivo
ARL 17477 (10 mg/kg; i.p.; once daily; days 5-14 after stroke) improves post-stroke functional recovery on the rotarod task in wild-type C57Bl6 male mice with transient middle cerebral artery occlusion without altering infarct volume[3].
ARL 17477 (0.4 mg/mL (0.9 mM); intraplantar injection; two prophylactic injections 15-20 minutes apart) does not prevent 7α,25-OHC (HY-113962)-induced mechanical allodynia in Sprague Dawley rats, but accelerates recovery to baseline within 96 hours[4].
