We previously reported that phenanthroindolizidine alkaloid 3 and its derivatives had markedly potent in vitro cytotoxicity. However, they had low in vivo antitumor activities and high in vivo toxicities, which was a serious problem. To address this problem, new phenanthroindolizidine derivatives were synthesized and their antitumor activities and toxicities were evaluated. This study describes the
我们先前曾报道过菲咯啉吲哚生物碱3及其衍生物在体外具有明显的细胞毒性。然而,它们具有低的体内抗肿瘤活性和高的体内毒性,这是一个严重的问题。为了解决这个问题,合成了新的菲咯啉吲哚衍生物,并评估了它们的抗肿瘤活性和毒性。这项研究描述了这些菲咯啉吲哚并咪唑衍生物的化学结构,抗肿瘤活性和毒性之间的关系。基于其性质,发现化合物8是最合适的潜在抗肿瘤剂。
