Application

GW405833 hydrochloride has been used as a lysosomal transient receptor potential mucolipin 1 (TRPML1) specific inhibitor to validate if TRPML1 mediates tau release in neurons and also to verify if it mediates the release of lysosomal tau. It has also been used as a TRPML channel blocker to study the effect of mucolipin transient receptor potential cation channel 3 (MCOLN3/TRPML3) function and trafficking on autophagy in HeLa cells.

Biochem/physiol Actions

GW405833 hydrochloride, also known as ML-SI1, is a cell-permeable lysosomal transient receptor potential cation channel, mucolipin subfamily (TRPML) blocker.
GW405833 is a selective cannabanoid CB2 receptor agonist; analgesic. GW405833 binds with high affinity at both human and rat CB2 receptors (Ki′s 3.9 and 3.6 nM); acts as a partial agonist (50% inhibition of forskolin-stimulated cAMP formation compared to full agonist CP55,940). GW405833 has potent analgesic activity in rat models of inflammatory, neuropathic and incisional pain; devoid of CNS effects common with CB1 agonists.

The anti-tumoral effects of cannabinoids have been described in different tumor systems, including pancreatic adenocarcinoma, but their mechanism of action remains unclear. We used cannabinoids specific for the CB1 (ACPA) and CB2 (GW) receptors and metabolomic analyses to unravel the

Gemcitabine (GEM, 2',2'-difluorodeoxycytidine) is currently used in advanced pancreatic adenocarcinoma, with a response rate of < 20%. The purpose of our work was to improve GEM activity by addition of cannabinoids. Here, we show that GEM induces both cannabinoid receptor-1

The members of the TRPML subfamily of non-selective cation channels (TRPML1-3) are involved in the regulation of important lysosomal and endosomal functions, and mutations in TRPML1 are associated with the neurodegenerative lysosomal storage disorder mucolipidosis type IV.

Transient receptor potential (TRP) mucolipins (TRPMLs), encoded by the MCOLN genes, are patho-physiologically relevant endo-lysosomal ion channels crucial for membrane trafficking. Several lines of evidence suggest that TRPMLs mediate localised Ca2+ release but their role in Ca2+ signalling is not

Neurofibrillary tangles (NFTs) composed of hyperphosphorylated and misfolded tau protein are a pathological hallmark of Alzheimer's disease and other tauopathy conditions. Tau is predominantly an intraneuronal protein but is also secreted in physiological and pathological conditions. The extracellular tau has
