cells, and siRNA knockdown of ACL limits cancer cell proliferation and reduces cancer stemness. We characterized a new class of ACL inhibitors bearing the key structural feature of the natural product emodin. Structure-activity relationship (SAR) study led to the identification of 1d as a potent lead that demonstrated dose-dependent inhibition of proliferation and cancer stemness of the A549 lung cancer
异常的细胞代谢驱动癌症的扩散和转移。ATP柠檬酸裂解酶(ACL)在产生胞质乙酰CoA方面起着至关重要的作用,胞质乙酰CoA是从头脂肪酸和胆固醇生物合成的关键组成部分。ACL在癌细胞中过表达,而ACL的siRNA敲低限制了癌细胞的增殖并降低了癌症的干性。我们表征了一类新型的ACL抑制剂,它们具有天然产物大黄素的关键结构特征。结构-活性关系(SAR)研究导致1d的鉴定作为有效的先导,证明了A549肺癌细胞系对增殖和癌干的剂量依赖性抑制。计算模型表明,这类抑制剂占据了变构结合位点,并阻止了柠檬酸底物进入其结合位点。
