Ru(II)-polypyridine complexes of the general formula [Ru(L1/L2)(phen)2]X2 (1a–6a) and [Ru(L1/L2)(bipy)2]X2 (1b–6b) (where X = ClO4, BF4, PF6; phen = 1,10-phenanthroline, bipy = 2,2′-bipyridine) were prepared by the reaction of [Ru(phen)2Cl2]·2H2O and [Ru(bipy)2Cl2]·2H2O with (E)-5-((4-methoxyphenyl)ethynyl)-N-(pyridin-2-ylmethylene)pyridin-2-amine (L1) and (E)-5-((4-nitrophenyl)ethynyl)-N-(pyridin-2-ylmethylene)pyridine-2-amine (L2) in the presence of NaBF4, NaClO4, and NaPF6. The electrochemical properties of all the complexes indicate reversible redox behavior corresponding to Ru(II)–Ru(III) couple and are susceptible to variation of electron-donating/accepting properties of substituent group on L1 and L2. All complexes showed room temperature luminescence corresponding to π→π* intra-ligand charge-transfer (ILCT) transition with chelation enhanced fluorescence and is finely tuned by increasing π-conjugation, size of counter anions, and variation of substituent group with different electronic effects in the complexes. All the complexes worked as an effective catalyst for the oxidation of benzyl alcohol to corresponding benzaldehyde in good yield at room temperature. (Figure presented.).

A new series of hexa-coordinated Ru(II) complexes of the type [Ru(L)(phen)2]X (1a–d) and [Ru(L)(bipy)2]X (2a–d) (where phen = 1,10-phenanthroline, bipy = 2,2′-bipyridine, X = NO3, BF4, ClO4, PF6) have been prepared by the reaction of (E)-2-(((5-((4-methoxyphenyl)ethynyl)pyridin-2-yl)imino)methyl)-4-((4-nitrophenyl)ethynyl)phenol (L) with [Ru(phen)2]Cl2·2H2O and [Ru(bipy)2]Cl2·2H2O. The complexes were characterized by physico-chemical and spectroscopic methods. All complexes are 1:1 conducting and diamagnetic in nature. In acetonitrile solution, the complexes displayed one reversible Ru(II)–Ru(III) oxidation couple and one irreversible Ru(III)–Ru(IV) oxidation and are sensitive to π-acidic character of phen and bipy ligands. The complexes show room-temperature luminescence originated from the lowest energy metal-to-ligand charge transfer excited state and are sensitive to difference in size of the counter anions. All the complexes displayed second harmonic generation by Kurtz-powder technique indicating their potential for the application as a useful NLO material.

Drug discovery faces economic and scientific imperatives to deliver lead molecules rapidly and efficiently. Using traditional paradigms the molecular design, synthesis, and screening loops enforce a significant time delay leading to inefficient use of data in the iterative molecular design process. Here, we report the application of a flow technology platform integrating the key elements of structure-activity relationship (SAR) generation to the discovery of novel Abl kinase inhibitors. The platform utilizes flow chemistry for rapid in-line synthesis, automated purification, and analysis coupled with bioassay. The combination of activity prediction using Random-Forest regression with chemical space sampling algorithms allows the construction of an activity model that refines itself after every iteration of synthesis and biological result. Within just 21 compounds, the automated process identified a novel template and hinge binding motif with pIC50 > 8 against Abl kinase - both wild type and clinically relevant mutants. Integrated microfluidic synthesis and screening coupled with machine learning design have the potential to greatly reduce the time and cost of drug discovery within the hit-to-lead and lead optimization phases.
