have been synthesized and biologically evaluated for geranylgeranyltransferase 1 (GGT1) and farnesyltransferase (FT) inhibition. The screening results revealed that 2 (IC50 = 2.4 μM) and 5 (IC50 = 3.1 μM) are potent GGT1 inhibitors (GGTIs), possessing higher inhibitory activity compared to the control compound 1 (IC50 = 3.3 μM). The anti-proliferative efficacy of these compounds was further assayed against
在这项研究中,已经合成了一系列基于吡唑的GGTI-DU40(1)的结构类似物,并对其生物学特性进行了香叶基香叶基转移酶1(GGT1)和法尼基转移酶(FT)抑制的评估。筛选结果显示2(IC 50 = 2.4μM )和5(IC 50 = 3.1μM)是有效的GGT1抑制剂(GGTIs),与对照化合物1(IC 50 = 3.3μM)相比,具有更高的抑制活性。进一步测定了这些化合物对MDA-MB-231细胞的抗增殖功效,表明 与1相比,其2的活性显着更高(IC 50 = 7.6μM)。(IC 50 = 23.0μM)。为了检查完整化合物在完整细胞中抑制GGT1的能力,对MDA-MB-231细胞系进行了蛋白质印迹分析,发现其具有极高的2和5抑制细胞活性,并证明了它们抑制NPG1异戊二烯化的能力。内源性蛋白质。分子对接研究2对与香叶基香叶基焦磷酸酯(GGPP)类似物和KKKSKTKTKVVIL肽底物的CaaX(C
