生物活性

製品説明	SF2523 is a highly selective and potent inhibitor of PI3K with IC50 values of 34 nM, 158 nM, 9 nM, 241 nM and 280 nM for PI3Kα, PI3Kγ, DNA-PK, BRD4 and mTOR, respectively.
in vitro	SF2523 blocks BRD4 binding to MYCN promoter PS1/PS2. It blocks M1-M2 transition and decreases levels of p-AKT, N-MYC in several neuroblastoma cell lines. SF2523 treatment decreases protein levels of MYCN and Cyclin D1, the MYCN target, and inhibits AKT activation by blocking phosphorylation of AKT at Ser473^[2]. SF2523 interacts robustly with the full-length BRD4 (Kd = 140 nM) and exhibits comparable affinity to the BRD4 first BD (BD1) (Kd =150 nM), however it binds more weakly to the second BD (BD2) of BRD4 (Kd = 710 nM). Comparison of binding affinities of SF2523 for BDs of other proteins reveals that it binds equally well to BDs of BRD4, BRD2, and BRD3; shows moderate binding to BDs of CECR2 and BRDT; but associates much weaker with other BDs^[3].
in vivo	SF2523 blocks spontaneous metastasis and tumor growth. SF2523 has demonstrated animal efficacy results without toxicity in the following 4 animal models: orthotopic pancreatic model, multiple myeloma model, renal cell carcinoma model, neuroblastoma xenograft model^[2]. SF2523 targets PI3K-driven and BRD4-driven oncogenic pathways in vivo. SF2523 is less toxic to the host organism in vivo than a combination of an equipotent PI3K inhibitor and BRD4 inhibitor^[3].
