GW4869 Targets Glioblastoma Progression and Chemoresistance
Researchers have identified the small‑molecule inhibitor GW4869 as a potent blocker of glioblastoma progression and chemoresistance. In pre‑clinical mouse models, GW4869 reduced tumor volume by roughly 45% and, when paired with temozolomide, extended median survival by 30%. The compound works by inhibiting neutral sphingomyelinase, curbing exosome‑mediated transfer of MGMT and other resistance factors. These findings suggest a new therapeutic avenue for patients with treatment‑refractory glioblastoma.
