A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

Monobasic ethers of 1,2-dihydropyrrolo[1,2-a]indole, 6H-isoindolo[2,1-a]indole, and 6H-benz[5,6]isoindolo[2,1-a]indole and bis-basic ethers of 6H-isoindolo[2,1-a]indole were prepared using an intramolecular Wittig cyclization as a key step. All these compounds were firstly evaluated for their cytotoxicity effects against L1210 cell line. Only the tetracyclic bis-basic ether 14d displayed submicromolar cytotoxic effect. Moreover, despite the fact that the presence of these two amino side chains in 14c, 14d, and 14f led to strong DNA binding effect, they are not topoisomerase II inhibitors. Among the monobasic ethers 14a, 14b, 22, and 29, which do not bind to DNA, the pentacyclic analog 29 exhibited micromolar cytotoxic activity against L1210 and HT-29 cell lines and induced a weak topoisomerase II inhibition.
