【摘要】 1:采用微波辐射与相转移催化联用技术,以自行合成的芳甲酰肼和对硝基苯甲酰氯为原料,采用一锅法合成出了10个酰氨基硫脲中间体化合物(5a～5j),其中有6个化合物(5d,5f～5j)为新化合物。将所得酰氨基硫脲(5)在无酸催化剂存在下以DMF为溶剂加热回流,脱水关环合成出了9个2,5-二取代-1,3,4-噻二唑类化合物(TM-I-6a～6i),其中有7个(TM-I-6b～6d,TM-I-6f～6i)为新化合物。为合成新目标化合物还合成了31个相关中间体化合物。这种合成1,3,4-噻二唑环的方法目前尚未见文献报道。此合成方法具有操作简单、反应条件温和、后处理简单、经济、环境友好等特点,体现了绿色化学的思想。利用IR、~1H NMR及元素分析确定了中间体及目标产物的结构。首次利用~1H NMR谱和熔点证明了酰氨基硫脲存在着链状和环状两种异构体,首次采用重结晶方法分离得到两种异构体,并得到了它们的IR和~1H NMR谱。对所合成的目标产物2,5-二取代-1,3,4-噻二唑类化合物TM-I-6a～6i进行了大肠杆菌甲硫氨酸肽酶-1(EcMetAP-1)和酵母甲硫氨酸肽酶-1(ScMetAP-1)抑制剂测试实验,实验结果表明:目标产物TM-I-6c,TM-I-6i对EcMetAP-1的抑制率为100%,抑制活性优于阳性对照物L288,TM-I-6g的抑制率为80%,三个样品抑制作用明显,抗菌活性较强。目标化合物TM-I-6c,TM-I-6d,TM-I-6e对ScMetAP-1的抑制作用明显,为100%完全抑制,抗菌活性非常强,抑制活性优于阳性对照物L288。这些研究结果对进一步研究噻二唑化合物的合成、结构解析、生物活性的研究、药物的开发具有十分重要的意义。2:以邻氨基苯酚和尿素为起始原料经一系列反应合成出了1O个新的具有噻二唑基团的苯并噁唑啉酮衍生物,即2-(芳甲酰氨基)-5-(2-苯并噁唑啉酮-3-甲基)-1,3,4-噻二唑。为合成新化合物还合成了23个相关的中间体化合物。在合成1,3,4-噻二唑环的步骤中采用酸催化脱水关环方法,提高了目标产物的产率。此方法反应时间短,产率高,后处理简单,合环步骤在室温下即可进行。目标化合物及中间体化合物的结构利用IR、~1H NMR、进行了结构表征。对所合成的目标分子,即苯并噁唑啉酮衍生物进行了人源甲硫氨酸肽酶-1(HsMetAP-1)和半胱氨酸天冬氨酸位点特异性蛋白水解酶-1(Caspase-1)抑制实验,结果表明:所合成苯并噁唑啉酮衍生物,对HsMetAP-1和Caspase-1无明显抑制活性。这些研究结果对进一步研究苯并噁唑啉酮衍生物的合成、结构修饰、生物活性的研究、新型非类固醇抗炎药物(NSAIDs)的开发具有十分重要的意义。3:以5-叔丁基-1,3-二甲苯和液溴为起始原料,经过溴代、氧化、酯化、Ullamnn偶联、环化反应最终合成出了具有光电活性的目标产物TM-Ⅲ-5,即7-叔丁基-13b-氮杂-萘并[3,2,1-de]蒽-5,9-二酮。目标化合物及中间体化合物的结构利用IR、~1H NMR进行了结构表征。在利用Ullamnn反应合成中间体三芳胺二酸时改进了文献的合成方法,采用了CuCl为催化剂、1,10-菲啰啉为配体,使反应时间大大缩短,产物的产率较高,简化了合成与后处理步骤。在合成目标产物7-叔丁基-13b-氮杂-萘并[3,2,1-de]蒽-5,9-二酮时,改进了文献对其的纯化方法,使后处理纯化操作简便,产率较高。此项工作的完成为我们合成出更多新型螺烯化合物、研究其性质提供了有利的实验数据,奠定了实验基础。更多还原
