  6′-Chloro-7- or 9-(2,3-dihydro-5H-4,1-benzoxathiepin-3-yl)-7H- or 9H-purines and their corresponding sulfones as a new family of cytotoxic drugs

  摘要：

  A series of 1-(2,3-dihydro-5H-4,1-benzoxathiepin-3-yl)pyrimidine derivatives were synthesized and two of them (8 and 9) showed a modest antiproliferative activity against the MCF-7 breast cancer cell line. We then decided to change the pyrimidine base for the more lipophilic 6'-chloropurine, and the N-9'purine (15) and N-7' purine (17) were obtained. The sulfone N-7'-alkylated-6-chloropurine 18 was the most active derivative. Compound 17 was found to be slightly more active than its regioisomer 15, with an activity similar to that of 5-fluorouracil as a reference drug. Encouraged by these values, we tested these compounds against both the HT-29 human colon cancer cell line and the IEC-6 normal rat intestinal epithelial cell line, and 15 was found to be 12.7-fold more active against HT-29 than versus IEC-6.

  Synthesis of novel 1-(2,3-dihydro-5H-4,1-benzoxathiepin-3-yl)-uracil and -thymine, and their corresponding S-oxidized derivatives

  摘要：

  On the basis of molecular variations on isosteric replacements from the prototype 1-(2,3-dihydro-5H- 1,4-benzodioxepin-3-yl)-5fluorouracil a series of 3-(2,3-dihydro-5H-4, 1-benzoxathiepin-3-yl)-uracil or -thymine O,N-acetals was prepared. The nature of the cis- and trans-sulfoxide isomers was established by means of their conformational analyses carried out with Sybyl and after comparing the theoretical results with the H-1 NMR responses of the target molecules. (RS)-3-(1,1-Dioxo-2,3-dihydro-5H-4,1-benzoxathiepin-3-yl)thymine and (IS*, 3S*)-1-(1-oxo-3,5-dihydro-2H-4,1-benzoxathiepin-3-yl)thymine were found to be inhibitors of the MCF-7 cell growth.
