Biological Activity

SRX3262 (SRX 3262) is a potent, triple action BTK, PI3K and BRD4 inhibitor with potency against BTK (IC50=35 nM), PI3Kδ (IC50=16 nM), PI3Kα (IC50=64 nM), and both bromodomains of BRD4 (IC50 BD1=228 nM, IC50 BD2=348 nM).
SRX3262 shows dose-dependent antiproliferative activity in MCL cell lines with IC50 of 0.62 μM, 0.13 μM, and 1.2 μM for JeKo-1, Mino, and Ibrutinib-resistant Granta cells, respectively.
SRX3262 simultaneously blocks three interrelated MCL driver pathways: BTK, PI3K-AKT-mTOR and MYC.
SRX3262 concomitantly binds to BTK, PI3K, and BRD4, exhibits potent in vitro and in vivo activity against MCL, and overcomes the Ibrutinib resistance resulting from the BTK-C481S mutation.
SRX3262 inhibits IgM-induced BTK and AKT phosphorylation and abrogates binding of BRD4 to MYC loci.
SRX3262 promotes c-MYC destabilization, induces cell cycle arrest and apoptosis, and shows antitumor activity in in vivo xenograft models.
