  • Azaindole-indole coupled derivatives, preparation methods and uses thereof
    Patent number: 8642765
    Abstract: A novel class of azaindole-indole coupled derivatives, their preparation methods, pharmaceutical compositions containing the same and the uses thereof. The common structural feature of these derivatives is that they are coupled by azaindole and indole bi-molecule at different positions, forming extended pi-conjugated systems. Such derivatives inhibited cell growth and proliferation by various mechanisms. The present compounds have improved solubility, increased bioavailability, and thus have enhanced drug actions, and reduced medical dosages and undesired responses.
    Type: Grant
