treatment for GBM, they often cause chemoresistance and remain ineffective with recurrent GBM. Alternative therapeutics against GBM are urgently needed in the clinic. We report herein the discovery of a class of inhibitors (YZ129 and its derivatives) of the calcineurin-NFAT pathway that exhibited potent anti-tumor activity against GBM. YZ129-induced GBM cell-cycle arrest at the G2/M phase promoted apoptosis
胶质母细胞瘤(GBM)是成人原发性脑肿瘤中最常见和最恶性的类型之一,预后不良。尽管烷基化剂(如替莫唑胺)被广泛用作GBM的一线治疗药物,但它们经常引起化学耐药性,并且对于复发性GBM仍然无效。临床上迫切需要针对GBM的替代疗法。我们在此报告了钙调神经磷酸酶-NFAT途径的一类抑制剂(YZ129及其衍生物)的发现,该抑制剂表现出针对GBM的有效抗肿瘤活性。YZ129诱导的G2 / M期GBM细胞周期停滞促进了细胞凋亡并抑制了肿瘤细胞的增殖和迁移。在分子水平上,YZ129直接与HSP90结合以拮抗其对钙调神经磷酸酶的伴侣作用,以消除NFAT核易位,并且还抑制其他原癌途径,包括缺氧,糖酵解和PI3K / AKT / mTOR信号转导轴。我们的数据强调了靶向促癌HSP90伴侣网络治疗GBM的潜力。
