Design, synthesis and use of peptoids in the diagnosis and treatment of cancer.

Genetic variations in cancer cells are the underpinning for the development of resistance and failure of the treatment by current anticancer drugs. Thus, an ideal drug must overcome failure of treatment and prevents development of drug resistance. There are a wide variety of emerging, easy to prepare and cost effective group of drugs that are collectively called peptoids or peptidomimetics. These new set of drugs exhibit distinct features including protease resistance, are non-immunogenic, do not hinder functionality and backbone polarity, and can adopt different conformations. These drugs have shown promise as diagnostic and therapeutic tools in a wide variety of diseases. Here, we discuss the recent advancement in the design and synthesis of peptoids and use of these drugs in the diganosis and treatment of a wide number of cancers of the lung, prostate, and breast.
