Reactions of (2-(pyren-1-ylmethylene)hydrazinyl)benzothiazole (L) with ruthenium(II) prefabricated precursors [RuHCl(CO)(EPh3)3] and [RuH2(CO)(EPh3)3] (E = P or As) afforded new Ru(II) complexes [RuCl(CO)(EPh3)2(L)] and [RuH(CO)(EPh3)2(L)] (E = P or As) (1–4). All the Ru(II) complexes (1–4) were characterized by IR, NMR spectroscopies, ESI-mass spectrometry and elemental analyses. The solid-state structures of Ru(II) complexes (2 and 3) were established by single crystal X-ray analyses and revealed distorted octahedral geometries around the ruthenium(II) ion and mono anionic bidentate N^N coordination mode for hydrazine ligand. The Ru(II) complexes 2 and 3 were also analyzed using Hirshfeld surface analysis and DFT calculations. Moreover, all the complexes (1–4) were utilized in the N-alkylation reactions of amines using alcohol. Complex 3 was found to be highly active towards N-alkylation of different aromatic amines with alcohol.

The membrane bound enzyme monoamine oxidase exist in two splice variants designated A and B (MAO-A and MAO-B) and are key players in the oxidative metabolism of monoamines in mammalians. Despite their importance and being a prevalent target for the development of inhibitors as drugs, no systematic study of substrate specificity has been reported. In this study we present a systematic study of the MAO-A and MAO-B substrate specificity profile by probing two series of phenethylamine analogs. Kmand kcatvalues were determined for four N-alkyl analogs 2 -5 and four aryl halide analogs 6-9 at MAO-A and MAO-B. A following in silico study disclosed a new adjacent compartment to the MAO-B substrate pocket defined by amino acids Tyr188, Tyr435, Tyr398, Thr399, Cys172 and Gly434. This new insight is important for the understanding of the substrate specificity of the MAO-B enzyme and will be relevant for future drug design within the field of monoamines.
