Description

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.
