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.
A novel 2,5-diphenyl-1,3,4-oxadiazole-based fluorescent sensor for multi-analyte, ratiometric and relay recognition of a through modulating ESIPT has been developed.

The complex [(VIVO)bipy(H2O)]2(μ-P2O7)}·3H2O (2) was readily obtained as a nanocrystalline powder by one-pot synthesis under mild conditions. Single crystals of 2 were grown at room temperature over 2 months, and its structure was determined. Fundamental catalytic activity was proven for this species by testing for oxidation of benzyl alcohol in air.

Thermal behaviour of NaH2PO4/NaHSO4 flame retardant system for polyurethane (PU) rigid foams was investigated by simultaneous TG/DTA under dynamic conditions. It has been found that the most probable mode of action of 5:3 (mass/mass) NaH2PO4/NaHSO4 system, which proved to be most efficient in PU flame retardation (in comparison with other NaH2PO4/NaHSO4 compositions), is based on formation of char-promoting phosphoric acids and on thermal stabilisation of PU macrochains by an excess of sodium dihydrogenphosphate.
