Description

General description

GW4869 is a commonly used pharmacological agent, which inhibits exosome generation. It blocks ceramide-mediated inward budding of multivesicular bodies (MVBs) and the release of mature exosomes from MVBs. GW4869 exhibits cytotoxicity to phosphatidylserine-expressing myeloma cells. It inhibits the secretion of IFN (interferon)-α by plasmacytoid dendritic cells (pDCs).

Application

GW4869 has been used:

• as an inhibitor of neutral sphingomyelinase and exosome biogenesis
• to analyse the effects of arsenic trioxide (ATO) treatment for hepatoma carcinoma HCCLM3 cells on ceramide production
• to determine the contributions of p75 neurotrophin receptor (p75^NTR) and tropomyosin receptor kinase A (TrkA)- coupled pathways to nerve growth factor (NGF)-induced thermal hypersensitivity in rats

Biochem/physiol Actions

A cell-permeable, potent, specific, non-competitive inhibitor of N-SMase (neutral sphingomyelinase)
