Reactive oxygen species (ROS) are produced as normal products of cellular metabolism, which are essential for numerous cell biological functions. Due to aberrant metabolism, oncogenic signaling activation and mitochondrial dysfunction, cancer cells generate excessive ROS that cause severe oxidative damage, finally leading to tumor cell death. Thioredoxin reductase (TrxR), as an important ROS-scavenging enzyme, is overexpressed in various human tumors and plays an important role in regulating intracellular redox homeostasis to protect cancer cells from cell death induced by substantial ROS. Hence, TrxR has emerged as a promising target for anticancer agent development. Currently, metallodrugs with anticancer activity, especially gold- and platinum-complexes, have an enormous impact on clinical cancer chemotherapy. This review provides a comprehensive overview of various metal complexes (gold, platinum, ruthenium, rhodium, iridium, iron, palladium, silver, antimony, bismuth, tin) targeting mammalian TrxR and discusses their cytotoxicity in tumor cells.

Selective covalent inhibition of kinases by targeting poorly conserved cysteines has proven highly fruitful to date in the development of chemical probes and approved drugs. However, this approach is limited to 200 kinases possessing such a cysteine near the ATP-binding pocket. Herein, we report a novel approach to achieve selective, irreversible kinase inhibition, by targeting the conserved catalytic lysine residue. We have illustrated our approach by developing selective, covalent PI3Kdelta inhibitors that exhibit nanomolar potency in cellular assays, and a duration of action >48 h in CD4+ T cells. Despite conservation of the lysine residue throughout the kinome, the lead compound shows high levels of selectivity over a selection of lipid and protein kinases in biochemical assays, as well as covalent binding to very few off-target proteins in live-cell proteomic studies. We anticipate this approach could offer a general strategy, as an alternative to targeting non-conserved cysteines, for the development of selective covalent kinase inhibitors.

Chemistry is traditionally divided into organic and inorganic chemistry. category: catalyst-palladium, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 52409-22-0

Treatment of 3-(1-hexynyl)perylene with Co2(CO)8 resulted in the formation of the dinuclear cobalt complex [Co 2(CO)6(mu-eta2-C4H 9CC-Per)] (Per = 3-perylenyl) (1). The perylene derivatives 3-(2,3,5,6-tetrafluorophenyl)perylene (PerC6F4H) and 3-(2,3,5,6-tetrafluorophenyl)-9(10)hexylperylene (C6-PerC 6F4H) were prepared and used to synthesize [AuR(CN tBu)] (R = PerC6F42a), [AuR(CN(C 6H2)-3,4,5-(OC12H25)3)] (R = PerC6F4 (3a), R = C6-PerC 6F4 (3b)), trans-[PdR(PR?3)2X] (R = PerC6F4, R? = Ph, X = I (4a)); (R = C 6-PerC6F4, R? = Ph, X = I (4b)); (R = PerC6F4, R? = Et, X = I (5a)); (R = C 6-PerC6F4, R? = Et, X = I (5b)); (R = PerC6F4, R? = Ph, X = NCS (6a)), and trans-[Pd(PerC6F4)(PEt3)2X] (X = Br (7a); X = I (8a)). The molecular structure of complexes 1, 2a, and 6a has been determined by X-ray diffraction analysis. The perylenyl fragments of complexes 2a or 6a are essentially planar and make dihedral angles to the tetrafluorophenyl plane of 57.49 (2a) and 77.75 (6a). No pi-pi stacking of perylenyl rings is observed in any of the three molecules, but 2a shows association of two monomers (arranged almost antiparallel), with an Au…Au distance of 3.114 A. DFT calculations were performed on the absorption spectra of representative PerC6F4Y (Y = H, F, Au(CNMe), PtBr(PMe3)2 and PdBr(PMe3) 2). All complexes exhibit fluorescence associated with the perylene fragment with emission quantum yields, in solution at room temperature, in the range 0.20-0.90 and emission lifetimes ?4 ns, and no significant differences in the emission maxima, due to an efficient electronic decoupling of the metal fragment from the HOMO and LUMO of the perylene chromophore. The latter is confirmed by DFT calculations.
