  Synthesis and anticancer activity of (RS)-9-(2,3-dihydro-1,4-benzoxaheteroin-2-ylmethyl)-9H-purines

  摘要：

  Herein are reported the synthesis and anticancer activity against the human breast cancer cell line MCF-7 of a series of substituted (RS)-9-(2,3-dihydro-1,4-benzoxathiin-2-ylmethyl)-9H-purine derivatives and (RS)-9-(2,3-dihydro-1,4-benzodioxin-2-ylmethyl)-9H-purine derivatives. When the Mitsunobu reaction was carried out between (RS)-2,3-dihydro-1,4-benzoxathiin-3-methanol and the heterocyclic bases 6-chloro-, 2,6-dichloro, and 6-bromo-purines under microwave-assisted conditions, a formal 1,4-sulfur migration takes place through two consecutive oxyranium and episulfonium rings, giving rise to the corresponding (RS)-9-(2,3-dihydro-1,4-benzodioxin-3-ylmethyl)-9H-purine derivatives, previously reported by us. The most active compound (RS)-2,6-dichloro-9-(2,3-dihydro-1,4-benzoxathiin-2-ylmethyl)-9H-purine shows an IC50 = 2.75 +/- 0.02 mu M. When the cancerous cells were treated with this compound, a significant increase of apoptotic cells (70.08 +/- 0.33%) was obtained in relation to the control ones. The induction of the G(2)/M cell cycle arrest and apoptosis by the three most active compounds is associated with increased phosphorylation of eIF2 alpha in human breast cancer cells.
