A series of oxadiazole derivatives possessing morpholine 6a–l were synthesized by nucleophilic substitution reaction of key intermediates [1,3,4]-oxadiazole-2-thiol derivatives 5a–l with 4-(2-chloroethyl) morpholine. Compounds 6a–l were evaluated for their in vitro and in vivo antitumor potential in Dalton’s Lymphoma Ascites (DLA) tumor cells. Among 6a–l series, compound 6a with concentration ∼8.5 μM
通过关键中间体[1,3,4]-恶二唑-2-硫醇衍生物5a-1与4-(2-氯乙基)吗啉的亲核取代反应,合成了一系列具有吗啉6a-1的恶二唑衍生物。对化合物6a–l在道尔顿淋巴瘤腹水(DLA)肿瘤细胞中的体外和体内抗肿瘤潜力进行了评估。其中图6a-1系列,化合物6A与浓度~8.5μM显示广泛的细胞毒性在体外的肿瘤体积和85%的减少体内,归因针对癌细胞优异的抗增殖能力。化合物6a已广泛抑制了微血管密度(MVD)或肿瘤新脉管系统,这从CD31免疫染色和腹膜H&E染色可见一斑。化合物6a的抗增殖活性的主要原因是由于肿瘤脉管系统的抑制。
