Phosphaplatins and their use in the treatment of cancers resistant to cisplatin and carboplatin

The present invention provides phosphaplatins, stable isolated monomeric phosphate complexes of platinum (II) and (IV), and methods of use thereof for treating cancers, including cisplatin- and carboplatin-resistant cancers. Unlike cisplatin, these complexes do not readily undergo hydrolysis and are quite soluble and stable in aqueous solutions. Moreover, these complexes—unlike cisplatin, carboplatin, and related platinum-based anti-cancer agents—do not bind DNA. Rather, data suggests that phosphaplatins trigger overexpression of fas and fas-related transcription factors and some proapoptotic genes such as Bak and Bax. Nevertheless, the complexes exhibit tremendous cytotoxicity towards cancer cells. Thus, the present invention provides novel platinum anticancer agents that have a different molecular target than those in the art.

Compositions and methods of treatment of drug resistant cancers

ActiveUS20140011759A1Synergize their apoptotic responseBiocideSugar derivativesAbnormal tissue growthPhosphorylation
Time-staggered inhibition of EGFR, in combination with DNA damaging agents, is a useful therapeutic strategy for treating cancers, particularly drug resistant cancers such as a subset of triple-negative tumors, particularly those with high basal levels of phosphorylated EGFR. The staggered therapy was also demonstrated to be applicable to other types of tumors, especially lung cancers, which contain either high levels of phosphorylated wild-type EGFR or mutations within EGFR itself. EGFR inhibition dramatically sensitizes cancer cells to DNA damage if the drugs are given sequentially, but not simultaneously. The first drug must be administered in a dosage and for a period of time sufficient for the dynamic network rewiring of an oncogenic signature maintained by active EGFR signaling to unmask an apoptotic process that involves activation of caspase-8.

Amooranin (AMR) has been found to cause tumor cell death through G2 / m cell cycle arrest, caspase activation, and apoptosis. Furthermore, it has been demonstrated that AMR is a substrate for P-glycoprotein. Based on these activities, AMR compounds can be used in the treatment of a number of diseases in which aberrant cellular proliferation occurs such as drug-sensitive and drug-resistant cancers, autoimmune disorders, and inflammatory diseases.
