Methylene homologues of chlorambucil were synthesised and conjugated to the labdane diterpene coronarin D. The products were evaluated for their in vitro cytotoxicity, and were found to exhibit selective activity against MOLT-3 cell line. Two homologues of chlorambucil showed a comparable cytotoxic effect to their parent. However, as compared with the non-derivatised chlorambucil and its homologues, their conjugation with coronarin D through ester linkage did not enhance in vitro cytotoxicity against the tested cancer cell lines.
合成了氯丁嘧啶的亚甲基同系物,并将其与唇烃二萜冠醚萜 D 共轭。对这些产品进行了体外细胞毒性评估,发现它们对 MOLT-3 细胞系具有选择性活性。氯霉素的两种同系物显示出与其母体相当的细胞毒性作用。不过,与未减活化的氯丁氨嘧啶及其同系物相比,它们通过酯键与冠突散囊菌素 D 共轭并没有增强对受测癌细胞株的体外细胞毒性。
