Golden Jubilee for Scorpionates. Recent Advances in Organometallic Chemistry and Their Role in Catalysis

This review aims to describe some recent trends in organometallic complexes containing scorpionate ligands. Particular attention will be paid to the ligands structure, reagents, and methods developed during the past decade and contextualize them within the broad field of organometallic chemistry. In fact, novel ligand design has itself become a fundamental part of most organometallic researches and many catalytic conversions have been attained by subtle modification of the metal environment through a careful choice of the ancillary ligands. This review, which is necessarily limited in scope, reports the organometallic complexes with azolylborate and azolylalkane ligands from 2008 until today and it is organized according to the metal center.

The potent 5-lipoxygenase-activating protein (FLAP) inhibitor 3-[3-tert-butylsulfanyl-1-[4-(6-ethoxypyridin-3-yl)benzyl]-5-(5-methylpyridin-2- ylmethoxy)-1H-indol-2-yl]-2,2-dimethylpropionic acid 11cc is described (AM803, now GSK2190915). Building upon AM103 (1) (Hutchinson et al. J. Med Chem.2009, 52, 5803-5815; Stock et al. Bioorg. Med. Chem. Lett. 2010, 20, 213-217; Stock et al. Bioorg. Med. Chem. Lett.2010, 20, 4598-4601), SAR studies centering around the pyridine moiety led to the discovery of compounds that exhibit significantly increased potency in a human whole blood assay measuring LTB4 inhibition with longer drug preincubation times (15 min vs 5 h). Further studies identified 11cc with a potency of 2.9 nM in FLAP binding, an IC50 of 76 nM for inhibition of LTB4 in human blood (5 h incubation) and excellent preclinical toxicology and pharmacokinetics in rat and dog. 11cc also demonstrated an extended pharmacodynamic effect in a rodent bronchoalveolar lavage (BAL) model. This compound has successfully completed phase 1 clinical studies in healthy volunteers and is currently undergoing phase 2 trials in asthmatic patients.

Mild and efficient palladium-catalyzed direct trifluoroethylation of aromatic systems by C-H activation

The introduction of trifluoroalkyl groups into aromatic molecules is an important transformation in the field of organic and medicinal chemistry. However, the direct installation of fluoroalkyl groups onto aromatic molecules still represents a challenging and highly demanding synthetic task. Herein, a simple trifluoroethylation process that relies on the palladium-catalyzed C-H activation of aromatic compounds is described. With the utilization of a highly active trifluoroethyl(mesityl)iodonium salt, the developed catalytic method enables the first highly efficient and selective trifluoroethylation of aromatic compounds. The robust catalytic procedure provides the desired products in up to 95 % yield at 25 C in 1.5 to 3 hours and tolerates a broad range of functional groups. The utilization of hypervalent reagents opens new synthetic possibilities for direct alkylations and fluoroalkylations in the field of transition-metal-catalyzed C-H activation.

Design, synthesis and biological study of potent and covalent HER-2 tyrosine kinase inhibitors with low cytotoxicity in vitro

The discovery and development of a novel HER-2 tyrosine kinase inhibitor for the treatment of HER2-positive breast cancer are presented in this article. EGFR family has been recognized as a crucial meditator in the cancer progression; HER-2 tyrosine kinase was one of the members among them. In the effort to explore potent HER-2 inhibitors, a novel series of 4-anilino-3-cyanoquinoline derivatives have been designed, synthesized and evaluated. Most compounds possessed modest proliferation inhibition on SK-BR-3 cell line and HER-2 kinase. Compound 16 appeared to be the most potent compound (HER-2 kinase IC50: 19.4?nM, SK-BR-3 IC50: 94?nM). In the experiment of cellular cytotoxicity assay, compound 16 shows a much lower cytotoxicity than neratinib on Beas-2b cell line (Human bronchial epithelial cells). In conclusion, compound 16 would be a promising lead compound for further anti-breast cancer drug discovery.
