Ulixertinib(BVD-523,AbMole,M5345)是一種高選擇性、可逆的細(xì)胞外信號調(diào)節(jié)激酶ERK1/2抑制劑,在多種細(xì)胞和動物模型中展現(xiàn)出顯著的靶向抑制活性。在神經(jīng)母細(xì)胞瘤(NB)研究中,Ulixertinib在低納摩爾濃度范圍內(nèi)即可有效抑制MAPK通路的活性,并顯著降低SK-N-BE(2)、IMR-32等NB細(xì)胞系的細(xì)胞增殖與集落形成能力,同時還能誘導(dǎo)細(xì)胞周期阻滯并促進(jìn)凋亡、增強(qiáng)NB細(xì)胞對阿霉素(Doxorubicin)的敏感性[1]。在膠質(zhì)瘤模型中,針對攜帶KIAA1549:BRAF融合或BRAFV600E突變的BT40和DKFZ-BT66細(xì)胞系,Ulixertinib(VRT752271)在體外以低納摩爾濃度抑制細(xì)胞活力,并在斑馬魚胚胎和小鼠體內(nèi)模型中證實(shí)其靶點(diǎn)抑制效應(yīng)及抗腫瘤作用[2]。
在橫紋肌肉瘤(RMS)研究中,
Ulixertinib(BVD-523,AbMole,M5345)與MCL-1抑制劑S63845聯(lián)用可在體外快速誘導(dǎo)Caspase活化及凋亡,并在小鼠模型中顯著抑制RMS細(xì)胞的長期存活,機(jī)制上涉及BIM和BMF的上調(diào)[3]。在胰腺導(dǎo)管腺癌(PDAC)細(xì)胞系如MIA PaCa-2和PANC-1中,Ulixertinib(CAS No.:869886-67-9)單一處理能有效抑制生長,并在與吉西他濱(Gemcitabine)聯(lián)用時表現(xiàn)出協(xié)同細(xì)胞毒性[4]。
在肺癌研究中,
Ulixertinib(BVD-523,AbMole,M5345)可有效逆轉(zhuǎn)RAD21驅(qū)動的轉(zhuǎn)移,尤其在KRAS突變背景下,在小鼠模型中顯著抑制肺腺癌(LUAD)進(jìn)展[5];此外,在腦轉(zhuǎn)移模型中,Ulixertinib能穿透血腦屏障,并在小鼠中減少腦轉(zhuǎn)移發(fā)生率、延長生存期[6]。藥代動力學(xué)研究表明,Ulixertinib(Gemzar)在小鼠、大鼠和犬中口服給藥后吸收迅速,半衰期介于1.0–2.5 h[7]。綜合來看,
Ulixertinib(BVD-523,AbMole,M5345)憑借其明確的靶向機(jī)制、良好的體內(nèi)暴露特性及廣泛的協(xié)同潛力,已成為解析MAPK通路功能及開發(fā)聯(lián)合干預(yù)策略的重要科研工具。
