In some cases, the catalyzed mechanism may include additional steps.In a article, 22990-19-8, molcular formula is C15H15N, introducing its new discovery.

Herein, the visible-light-induced dehydrogenation of N-heterocycles such as tetrahydroquinolines, tetrahydroisoquinolines, and indolines in O2-containing suspensions of a commercially available titanium dioxide photocatalyst yielding the corresponding heteroarenes is presented. 4-Amino-2,2,6,6-tetramethylpipiridinyloxyl (4-amino-TEMPO) was found to exhibit a beneficial role, as it increased the yield and improved the selectivity of the dehydrogenation reaction. Both the selectivity and the yield are further enhanced by grafting 0.1 wt % of Ni(II) ions onto the TiO2 surface. It is proposed that the basic reactant adsorbs at Lewis acid sites present at the TiO2 surface. The dehydrogenation reaction is initiated by visible-light excitation of the resulting surface complex and a subsequent single-electron transfer from the excited N-heterocycle via the conduction band of TiO2 to O2. Ni(II) ions possibly serve as an electron transfer bridge between the conduction band of TiO2 and O2, while the TEMPO derivative is assumed to act as a selective redox mediator involved in reactions of the generated reactive oxygen species.

Antithrombin is a key regulator of coagulation and prime target of heparins, clinically used anticoagulants. Heparins induce a two-step conformational activation of antithrombin, a process that has remained challenging to target with molecules devoid of the antithrombin-binding pentasaccharide DEFGH. Computational screening of a focused library led to the design of two tetra-sulfated N-arylacyl tetrahydroisoquinoline variants as potential nonsaccharide activators of antithrombin. A high yielding synthetic scheme based on Horner-Wadsworth-Emmons or Pictet-Spengler reactions was developed to facilitate the functionalization of the tetrahydoisoquinoline ring, which upon further amidation, deprotection, and sulfation gave the targeted nonsaccharide activators. Spectrofluorometric measurement of affinity displayed antithrombin binding affinities in the low to high micromolar range at pH 6.0, I 0.05, 25 C. Measurement of second-order rate constants of antithrombin inhibition of factor Xa in the presence and absence of the designed activators showed antithrombin activation in the range of 8-80-fold in the pH 6.0 buffer. This work puts forward 20c, a novel tetra-sulfated N-arylacyl tetrahydroisoquinoline-based molecule, that activates AT only 3.8-fold less than that achieved with DEFGH, suggesting a strong possibility of rationally designing sulfated organic molecules as clinically relevant AT activators.

A series of phosphonamide-based hydroxamate derivatives were synthesized, and the inhibitory activities were evaluated against various metalloproteinases in order to clarify its selectivity profile. Among the four diastereomeric isomers resulting from the chirality at the C-3 and P atoms, the compound with a (R,R)-configuration both at the C-3 position and the phosphorus atom was found to be potently active, while the other diastereomeric isomers were almost inactive. A number of (R,R)-compounds synthesized here exhibited broad spectrum activities with nanomolar Ki values against MMP-1, -3, -9, and TACE and also showed nanomolar IC50 values against HB-EGF shedding in a cell-based inhibition assay. The modeling study using X-ray structure of MMP-3 suggested the possible binding mode of the phosphonamide-based inhibitors.

Syntheses of 2,6-bis[((3S)-3-(methoxycarbonyl)-1,2,3,4- tetrahydroisoquinolin-2-yl)carbonyl]pyridine and its coordination compounds with Cu2+, Co2+, Co3+, or Fe3+ are described. By means of 1H- and 13C-NMR spectra it was proved that 2,6-bis[((3S)-3-(methoxycarbonyl)-1,2,3,4-tetrahydroisoquinolin-2- yl)carbonyl]pyridine as well as its coordination compound with Co3+ exist in the form of a mixture of three conformers, differing in the conformations at the two amide groups present. The prepared coordination compounds were tested in the enantioselective catalysis of the nitroaldol addition of nitromethane with 2-nitrobenzaldehyde or 4-nitrobenzaldehyde, and in the Michael addition of ethyl 2-oxocyclohexanecarboxylate to but-3-en-2-one.
