摘要：

[目的]基于Integrity数据库的药物信息分析天然抗肿瘤药的发展态势。[方法]在Integrity数据库中对天然抗肿瘤药的药物信息进行检索、采集、清洗,采用文献计量学方法从研发阶段、治疗领域、化合物类型等多个方面对天然抗肿瘤药研发现状和发展态势进行深入分析。[结果]Integrity数据库中收录天然抗肿瘤药物信息有4403条,其中3291条药物信息涉及先导化合物;研究发现,处于生物学实验阶段的药物最多,有3051个;从治疗领域来看,溶瘤药物的数量最多(3258个),其次是抗肿瘤抗生素(504个)和化学预防剂(215个);植物(2646个)是天然抗肿瘤药的主要天然来源;化合物类型以生物碱(332个)、类固醇(323个)和皂苷(304个)为主;作用靶点有300多种,其中Na+/K+-ATP酶是药物作用最多的靶点,有153个;从作用机制看,有300多种分子机制,其中一氧化氮生成抑制剂(140个)和NF-κB活化抑制剂(107个)数量优势明显;细胞机制有30多种,以细胞凋亡诱导剂(728个)和信号转导调控剂(679个)为主;注射剂(149个)是最主要的给药途径。[结论]天然抗肿瘤药是肿瘤领域非常重要的研究方向。通过对天然抗肿瘤药的药物信息进行深入分析,可以了解该领域的研究现状和发展态势,为肿瘤研究和新药研发提供一定的借鉴和参考。
