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.

A series of mononuclear ruthenium polypyridyl complexes [Ru(Mebimpy)(pic)3](PF6)2 (2; Mebimpy=2,6-bis(1-methylbenzimidazol-2-yl)pyridine; pic=4-picoline), Ru(bimpy)(pic)3 (3; H2bimpy=2,6-bis(benzimidazol-2-yl) pyridine), trans-[Ru(terpy)(pic)2Cl](PF6) (4; terpy=2,2?;6?,2″-terpyridine), and trans-[Ru(terpy)(pic) 2(OH2)](ClO4)2 (5) are synthesized and characterized as analogues of the known Ru complex, [Ru(terpy)(pic) 3](PF6)2 (1). The effect of the ligands on electronic and catalytic properties is studied and discussed. The negatively charged ligand, bimpy2-, has a remarkable influence on the electrochemical events due to its strong electron-donating ability. The performance in light- and CeIV-driven (CeIV=Ce(NH 4)2(NO3)6) water oxidation is successfully demonstrated. We propose that ligand exchange between pic and H2O occurs to form the real catalyst, a Ru-aqua complex. The synthesis and testing of trans-[Ru(terpy)(pic)2(OH 2)](ClO4)2 (5) confirmed our proposal. In addition, complex 5 possesses the best catalytic activity among these five complexes.

Carbonic anhydrase (CA) has been widely used in gas separation membranes because of its high affinity for CO2 molecules. In this work, a novel biomimetic material (Co-2,6-bis(2-benzimidazolyl)pyridine, CoBBP) which has a similar molecular structure to the CA enzyme but with higher stability and a lower price was successfully synthesized. The excellent thermal stability, dispersibility and high CO2 selectivity make CoBBP a promising alternative to CA. Then, a series of Pebax-CoBBP mixed matrix membranes were constructed to explore their capability for CO2/N2 separation. Compared to the pristine Pebax-1657, the Pebax-CoBBP mixed matrix membrane with the optimized 1.33 wt% CoBBP loading showed an improved CO2 permeability of 675.5 barrer and a CO2/N2 selectivity of 62, surpassing the Robeson upper bound (2008). Furthermore, the hydrogen bonds between CoBBP and polyamide chains improved the chain stiffness of the linear glassy polymer, ensuring good operational mechanical stability. In short, this work could provide a promising method to exploit alternatives to the CA enzyme and to fabricate biomimetic membranes.

2,6-Bis(benzimidazol-2-yl)pyridine (BBP/CSFA-0) was identified in a CPE-based screening as a selective inhibitor of the in vitro bovine viral diarrhea virus (BVDV) replication. The EC50-values for the inhibition of BVDV-induced cytopathic (CPE) effect, viral RNA synthesis and the production of infectious virus were 0.3 ± 0.1 muM, 0.05 ± 0.01 muM and 0.3 ± 0.04 muM, respectively. Furthermore, BBP/CSFA-0 inhibits the in vitro replication of the classical swine fever virus (CSFV) with an EC 50 of 0.33 ± 0.25 muM. BBP/CSFA-0 proved in vitro inactive against the hepatitis C virus, that belongs like BVDV and CSFV to the family of Flaviviridae. Modification of the substituents on the two 1H-benzimidazole groups of BBP resulted in analogues equipotent in anti-BVDV activity (EC 50 = 0.7 ± 0.1 muM), devoid of cytotoxicity (S.I. = 142). BBP resistant BVDV was selected for and was found to carry the I261M mutation in the viral RNA-dependent RNA polymerase (RdRp). Likewise, BBP-resistant CSFV was selected for; this variant carries either an I261N or a P262A mutation in NS5B. Molecular modeling revealed that I261 and P262 are located in a small cavity near the fingertip domain of the pestivirus polymerase. BBP-resistant BVDV and CSFV proved to be cross-resistant to earlier reported pestivirus inhibitors (BPIP, AG110 and LZ37) that are known to target the same region of the RdRp. BBP did not inhibit the in vitro activity of recombinant BVDV RdRp but inhibited the activity of BVDV replication complexes (RCs). BBP interacts likely with the fingertip of the pestivirus RdRp at the same position as BPIP, AG110 and LZ37. This indicates that this region is a “hot spot” for inhibition of pestivirus replication.
