  摘要：

  强大的胸苷酸​​合酶（TS）抑制剂N- [4- [N-[（2-氨基-3,4-二氢-4-氧代-6-喹唑啉基）甲基] -N-prop-对双环系统的修饰2-炔基氨基]苯甲酰基] -L-谷氨酸（1，CB3717）已导致合成了一系列在C2和C4位带有多个取代基的喹啉抗叶酸酯。通常，合成途径包括将适当的N- [4-（丙-2-炔丙基氨基）苯甲酰基] -L-谷氨酸二乙酯与二取代的6-（溴甲基）喹啉偶联，然后使用弱碱将其脱保护。测试了该化合物作为部分纯化的L1210 TS的抑制剂。作为细胞毒性的量度，测试了化合物对培养物中L1210细胞生长的抑制作用。发现含有氯，氨基，在C2位的甲基取代基或在C4位的氯或溴取代基。改变2h N10取代基对酶的抑制作用与在含喹唑啉酮的叶酸中观察到的相似，表明喹啉化合物可能以与喹唑啉酮类似的方式与酶相互作用。同样，将2'-氟取代基引入几种喹啉类抗叶酸剂的苯甲酰基环中会导致TS抑

  the recently described (E)-2-(5-((4-methoxy-2-(trifluoromethyl)quinolin-6-yl)methoxy)-2-((4-(trifluoromethyl)benzyl)oxy)-benzylidene)-hexanoic acid (MTTB, T-10017) is a promising prototype for a new class of PPARγ antagonists. It exhibits competitive antagonism against rosiglitazone mediated activation of PPARγ ligand binding domain (PPARγLBD) in a transactivation assay in HEK293T cells with an IC50

  过氧化物酶体增殖物激活受体γ（PPARγ）调节剂已发现广泛用于治疗癌症，代谢紊乱和炎症性疾病。与PPARγ激动剂相反，对PPARγ拮抗剂的研究较少，尽管它们显示出免疫调节作用，但市场上仍没有治疗上有用的PPARγ拮抗剂。相反引起的2-氯-5-硝基苯甲酰苯胺（GW9662）非竞争性的，不可逆抑制，则最近描述（Ë）-2-（5-（（4-甲氧基-2-（三氟甲基）喹啉-6-基）甲氧基）-2-（（4-（三氟甲基）苄基氧基）-亚苄基）己酸（MTTB，T -10017）是新型PPARγ拮抗剂的有希望的原型。在HEK293T细胞的反式激活测定中，它对罗格列酮介导的PPARγ配体结合域（PPARγLBD）的活化具有竞争性拮抗作用，对1 µM罗格列酮的IC 50为4.3 µM。这项研究的目的是研究MTTB支架的结构-活性关系（SAR），重点是改善其理化特性。通过这种优化，制备并表征了34种新的衍生物。鉴定了两种
