描述 | ARV-771 is a PROTAC targeting on pan-BET, containing a BRD4-binding moiety (JQ-1) and a VHL-binding moiety. Treatment with ARV-771 led to an efficient degradation of BRD2, 3 and 4 in CRPC cell lines (22Rv1, VCaP, and LnCaP95 cell lines) at concentration of 4, 11 and 34nM post 16h, and achieved a superior suppression of c-MYC on mRNA level at concentration of 10nM post 16h compared with BET small molecular inhibitor JQ-1 and OTX-015. Consistent with this effect on c-MYC by ARV-771, ARV-771 caused higher levels of CRPC cell growth inhibition and cell apoptosis compared with the treatment with JQ-1, OTX-015 and enzalutamide. Unlike BET inhibitors, the attenuation of AR signaling and AR levels could also be observed after ARV-771 treatment. Administration of ARV-771, s.c., once daily demonstrated efficiency in multiple tumor xenograft models of CRPC at various doses ranging in 3-30mg/kg. ARV-766 works as a negative control of ARV-771[1]. |
