Most cytotoxic agents bind DNA's
major groove, have little sequence-specificity, and are severely toxic to normal tissues (including topoisomerase inhibitors, such as camptothecins and anthracyclines).
The compound [Fe2L3]4+ is an iron triple helicate with three organic strands wrapped around two iron centres to give a helix which looks cylindrical in shape and neatly fits within the
major groove of a DNA helix.
Prior to this discovery, most cancer drugs have targeted binding to the
major groove in DNA leading to the successful introduction of several new classes of anticancer drugs, including topoisomerase inhibitors such as camptothecins and anthracyclines.
It is the only chemotherapy agent that binds to the DNA's minor groove and bends toward the
major groove, producing its therapeutic effect by interfering with various cell division processes.
But even though he trails the Goose by six shots Tiger Woods is back in the
Major groove again after winning the Masters at Augusta in April.
They managed to produce a synthetic molecule which is big enough to bind with the
major groove of the DNA where most of the action is.
Trabectedin binds to the minor groove of DNA and bends it toward the
major groove, causing DNA adducts that interfere with cell division and genetic transcription processes and DNA repair machinery.
Pixantrone (BBR 2778) is a novel
major groove binder with an aza-anthracenedione molecular structure that differentiates it from the anthracyclines and other related chemotherapy agents.
