derivatives with dual activity. The novel spiro-carbocyclic substituted hydantoin analogues were rationally designed, synthesized and evaluated for their potency against three HCV genotypes (1b, 3a, 4a), DENV and two Trypanosoma species (T. brucei, T. cruzi). They exhibited significant EC50 values and remarkable selectivity indices. Several modifications were undertaken to further explore the structure activity
丙型肝炎病毒 (HCV) 和登革热病毒 (DENV) 等黄病毒科病毒感染对全球健康构成威胁。受感染的个体分别有发展为慢性肝功能衰竭或出血热的风险,如果不及时治疗,通常会导致致命的后果。由锥虫属物种的热带寄生虫引起的疾病,T. brucei 和 T. cruzi,在撒哈拉以南非洲和拉丁美洲大陆构成了重大的社会经济负担,但药物开发资金不足。抗 HCV 化疗具有严重的副作用和高成本,而登革热尚无临床批准的治疗方法,抗寄生虫药物已过时且难以给药。此外,耐药性是一个新出现的问题。因此,迫切需要新的革命性化学疗法。通过利用分子框架组合方法,我们将两种具有抗病毒和杀锥虫活性的不同化学实体组合成一种由乙酰氧肟酸基团 (CH2CONHOH) 附着的新型混合支架,旨在制备具有双重活性的衍生物。合理设计、合成了新型螺碳环取代的乙内酰脲类似物,并评估了它们对三种 HCV 基因型(1b、3a、4a)、DENV 和两种锥虫属(T
