Description ERX-41 is an orally active, stereospecific small molecule that targets lysosomal acid lipase A (LIPA). It induces endoplasmic reticulum (ER) stress, leading to cell death independently of its LIPA activity yet reliant on its ER localization, suggesting a role in targeted solid tumor therapies [1].
In vitro ERX-41(1μM;0-30小时)对MDA-MB-231细胞死亡具有诱导作用,而对正常人乳腺上皮细胞(HMECs)则无显著效应[1]。在4小时内,ERX-41(1μM;2小时,4小时)引发内质网显著扩张,并在2小时内致使外周内质网出现紊乱[1]。此外,ERX-41(1μM;0.5-4小时)通过激活p-PERK与p-eIF2-α,触发下游的未折叠蛋白反应(UPR)通路[1]。
In vivo ERX-41(10 mg/kg;口服或腹腔注射;单次剂量)无论是通过口服还是腹腔注射,在1.5小时内均可在肿瘤组织中检出[1]。口服ERX-41(10 mg/kg;单次剂量)在MDA-MB-231异种移植小鼠模型中显著地抑制了肿瘤的生长,同时未造成小鼠体重的变化[1]。同样的剂量和给药方式对D2A1异种移植小鼠模型也显著地延缓了疾病的进展[1]。
