The objective of this study is to develop good cancer drugs to save cancer patients. Good cancer drugs are the drugs capable of inactivating abnormal methylation enzymes (MEs) to take out both cancer stem cells (CSCs) and cancer cells (CCs) by inducing these cells to undergo terminal differentiation, and to restore chemo-surveillance to save cancer patients. Bad cancer drugs are cytotoxic agents that can kill CCs but cannot affect CSCs, which can also destroy chemo-surveillance to contribute to the fatality of advanced cancer patients. Cell differentiation agent-2 (CDA-2) is a persuasive good cancer drug approved by the Chinese FDA. CDA-2 is a preparation of wound healing metabolites purified from urine, which can serve as a model for the development of CDA formulations as good cancer drugs. Wound healing metabolites active as differentiation inducers (DIs) and differentiation helper inducers (DHIs) are the active players of chemo-surveillance created by the nature as allosteric regulators of abnormal methylation enzymes (MEs). The elimination of abnormal MEs is very critical to the success of cancer therapy. Wound healing is a simple matter that comes naturally, because the nature creates chemo-surveillance to ensure perfection of wound healing. Cancer is the consequence of wound unhealing due to the collapse of chemo-surveillance. Cancer therapy can also be a simple matter, if the therapy follows wound healing process. PSCs and CSCs are cells with abnormal MEs, which are protected by drug resistance and anti-apoptosis mechanisms. PSCs are the cells involved in wound healing. Efficient induction of terminal differentiation of PSCs is very critical to the success of wound healing. Natural DIs and DHIs are the partners of PSCs and CSCs in wound healing, which can easily access to PSCs and CSCs. If wound is not healed, PSCs are forced to evolve into CSCs and then to progress to faster growing CCs. CCs display a high level of degradative enzymes to generate substrates for the syntheses of macro-molecules to support their faster growth. Natural DIs and DHIs may be rapidly degraded in CCs. A different set of unnatural DIs and DHIs may be necessary to achieve the induction of terminal differentiation of CCs. Thus, two sets of CDA formulations, one CDA-CSC with natural DIs and DHIs, and another CDA-CC with non-natural DIs and DHIs to accomplish induction of terminal differentiation of both CSCs and CCs to achieve effective therapy of cancer.
