e13665 Background: ACTB-1003 is an oral kinase inhibitor targeting cancer mutations (FGFR inhibition), angiogenesis (inhibition of VEGFR2 and Tie-2) and induces apoptosis (targeting RSK and p70S6K, downstream of PI3 kinase). The multi-activity of ACTB- 1003 translates to in vivo efficacy with dose-dependent tumor growth inhibition in a variety of histological cancers including lung, breast and colorectal. Results: ACTB-1003 is an oral kinase inhibitor with multiple modes of action, targeting cancer mutations via FGFR inhibition FGFR1 (IC50=6 nM), angiogenesis through inhibition of VEGFR2 (2 nM), Tie-2 (4 nM), and induces apoptosis likely by targeting RSK (5 nM) and p70S6K (32 nM). ACTB-1003 is highly active with dose-dependent tumor growth inhibition in cell lines with FGFR genetic alterations - OPM2 human multiple myeloma and the murine leukemia Ba/F3-TEL-FGFR1. OPM2 cells harbor the FGFR3 t(4:14) translocation, FGFR3 K650E mutation and PTEN deletion while the Ba/F3-TEL-FGFR1 cells are driven by FGFR1 ov...

ACTB-1003:一种针对癌症突变 (FGFR)、血管生成 (VEGFR2、TEK) 和细胞凋亡诱导 (RSK 和 p70S6K) 的口服激酶抑制剂。

e13665 背景:ACTB-1003 是一种口服激酶抑制剂,靶向癌症突变(FGFR 抑制)、血管生成(抑制 VEGFR2 和 Tie-2)并诱导细胞凋亡(靶向 RSK 和 p70S6K,PI3 激酶的下游)。ACTB-1003 的多活性转化为体内功效,在多种组织学癌症(包括肺癌、乳腺癌和结肠直肠癌)中具有剂量依赖性肿瘤生长抑制作用。结果:ACTB-1003 是一种具有多种作用模式的口服激酶抑制剂,通过 FGFR 抑制 FGFR1 (IC50=6 nM) 靶向癌症突变,通过抑制 VEGFR2 (2 nM)、Tie-2 (4 nM) 来靶向血管生成,并诱导细胞凋亡可能是通过靶向 RSK (5 nM) 和 p70S6K (32 nM)。ACTB-1003 在具有 FGFR 基因改变的细胞系 - OPM2 人多发性骨髓瘤和鼠白血病 Ba/F3-TEL-FGFR1 中具有高度活性,具有剂量依赖性肿瘤生长抑制作用。OPM2 细胞具有 FGFR3 t(4:14) 易位、FGFR3 K650E 突变和 PTEN 缺失,而 Ba/F3-TEL-FGFR1 细胞由 FGFR1 ov...
