The present invention relates to novel TMPK inhibitor compositions and their methods of use. In particular, it relates to novel TMPK inhibitor compositions and therapeutics that lead to dUTP-mediated DNA repair in tumor cells and acts as a novel chemosensitizer, which are useful in methods for treating or preventing cancers.

) Complexes with Acylated Piperazine Linker and Catalytic Activity in Three Types of C—C Coupling Reactions
salts LH2·Cl2 and LH2·(PF6)2 with acylated piperazine linker and two N‐heterocycliccarbene (NHC) silver(I) and palladium(II) complexes [L2Ag2](PF6)2 (1) and [L2Pd2Cl4] (2) were prepared. The crystal structures of LH2·Cl2 and 1 were confirmed by X‐ray analysis. In 1, one 26‐membered macrometallocycle was generated through two silver(I) ions and two bidentate ligands L. The catalytic activity of 2 was

Stable photoactive organogels were successfully prepared by a two-step sequence involving: 1) formation of thermoreversible organogels by use of a combination of low-molecular-weight organogelators (LMOGs) and ZnII-phthalocyanine (ZnII-Pc) moieties containing complementaryorganogelatorstructures, and 2) strengthenhancement of the gels by in situcross-linking with the aid of CuI-catalysed azide-alkyne

formation mediated by the human 5-HT(1B) receptor (formerly the 5-HT(1Dbeta) receptor) demonstrate that all of these serotonin dimers behave as full agonists. Among them, the piperazide derivatives of bis-serotonin, 4g,j, were also identified as very potent agonists in contracting the New Zealand white rabbit saphenous vein (pD2 = 7.6 in each case compared to 5.8 for sumatriptan). Results analysis supports
A simple chemosensor (1) has been designed and synthesized. The chemosensor selectively recognizes Hg2+ ions in THF–H2O (3 : 1, v/v) by showing a significant increase in emission and a bluish color of the solution under exposure to UV light. Change of the fluorophore unit in 1 leads to 2, which also shows selective sensing of Hg2+ under similar conditions. Furthermore, while the ensemble of 1 with Hg2+ selectively senses reduced glutathione (GSH) over cysteine and homocysteine, the ensemble of 2 with Hg2+ has been observed to be inefficient to distinguish glutathione from other biothiols. Thus probe 1 and inputs Hg2+ and GSH can be used to develop an INHIBIT logic gate.
