pursued goals by medicinal chemistry research. Most of the compounds clinically used as a treatment owe their efficacy to their cytotoxic interaction (direct or indirect) with nuclear DNA. This interaction results in the inhibition of DNA synthesis and the degradation of nucleic strands. Ellipticine is a naturally occurring 6H-pyrido[4,3-b]carbazole alkaloid endowed with antitumor activity, and several
人类癌症的治疗是药物化学研究追求的目标之一。临床上大多数用于治疗的化合物的功效归因于它们与核DNA的细胞毒性相互作用(直接或间接)。这种相互作用导致DNA合成的抑制和核酸链的降解。玫瑰树碱是一种具有抗肿瘤活性的天然6H-吡啶并[4,3-b]咔唑生物碱,几种玫瑰树碱衍生物已用于临床试验。我们先前报道了一些与玫瑰树碱结构相关的1,4-二甲基-9H-咔唑衍生物。我们研究的目的是在前药中转化吡啶并咔唑,使其在肿瘤细胞中具有更大的渗透能力并阻止其复制。我们的前药在人血浆中相应的酸中缓慢水解。从这些初步结果,我们推断我们的化合物可以阻断细胞复制。我们的假设是,抗肿瘤活性可能与DNA损伤的诱导有关,而短期内不会发生细胞裂解。
