Effects of a 3-alkyl-, 4-hydroxy- and/or 8-aromatic-substituent on the phenylethanolamine N-methyltransferase inhibitor potency and alpha2-adrenoceptor affinity of 2,3,4,5-tetrahydro-1H-2-benzazepines

2,3,4,5-Tetrahydro-1H-2-benzazepine (THBA; 1) is nearly 100-fold more selective an inhibitor of phenylethanolamine N-methyltransferase (PNMT, EC 2.1.1.28) versus the alpha2-adrenoceptor than is 1,2,3,4-tetrahydroisoquinoline (THIQ; 2) (1: PNMT Ki = 3.3 muM, alpha2-adrenoceptor Ki = 11 muM, selectivity [alpha2 Ki/PNMT Ki] = 3.3; 2: PNMT Ki = 9.7 muM, alpha2 Ki = 0.35 muM, selectivity = 0.036;). Since the PNMT inhibitory activity and selectivity of THIQ were enhanced by the introduction of a hydrophilic electron-withdrawing 7-substituent and a 3-alkyl-substituent, a similar study was conducted on THBA. 8-Nitro-THBA (3) was found to be as potent an inhibitor of PNMT as its THIQ analogue (21) and to be more selective due to its reduced alpha2-adrenoceptor affinity (3: PNMT Ki = 0.39 muM, alpha2 Ki = 66 muM, selectivity = 170; 21: PNMT Ki = 0.41 muM, alpha2 Ki = 4.3 muM, selectivity = 10). Introduction of a 3-alkyl substituent on the THBA nucleus decreased both the alpha2-adrenoceptor affinity and the PNMT inhibitory activity, suggesting an area of steric bulk intolerance at both sites. 4-Hydroxy-THBA (15), which can be considered a conformationally-restricted analogue of 3-hydroxymethyl-THIQ (30), exhibited poorer PNMT inhibitory activity and less selectivity than 30 (15: PNMT Ki = 58 muM, alpha2 Ki = 100 muM, selectivity = 1.7; 30: PNMT Ki = 1.1 muM, alpha2 Ki = 6.6 muM, selectivity = 6.0). While the addition of an 8-nitro group to 15 increased the selectivity of 16 as compared to its THIQ analogue (31), it was not as potent at PNMT nor as selective as 8-nitro-THBA (3) (16, PNMT Ki = 5.3 muM, alpha2 Ki = 680 muM, selectivity = 130; 31: PNMT Ki = 0.29 muM, alpha2 Ki = 19 muM, selectivity = 66). Compound 3 is the most selective (PNMT/alpha2) and one of the more potent at PNMT compounds yet reported in the benzazepine series, and should have sufficient lipophilicity to penetrate the blood-brain barrier (CLogP = 1.8).

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 17680-55-6 is helpful to your research. Synthetic Route of 17680-55-6

Fluorescent and Biocompatible Ruthenium-Coordinated Oligo(p-phenylenevinylene) Nanocatalysts for Transfer Hydrogenation in the Mitochondria of Living Cells

It is challenging to design metal catalysts for in situ transformation of endogenous biomolecules with good performance inside living cells. Herein, we report a multifunctional metal catalyst, ruthenium-coordinated oligo(p-phenylenevinylene) (OPV-Ru), for intracellular catalysis of transfer hydrogenation of nicotinamide adenine dinucleotide (NAD+) to its reduced format (NADH). Owing to its amphiphilic characteristic, OPV-Ru possesses good self-assembly capability in water to form nanoparticles through hydrophobic interaction and pi?pi stacking, and numerous positive charges on the surface of nanoparticles displayed a strong electrostatic interaction with negatively charged substrate molecules, creating a local microenvironment for enhancing the catalysis efficiency in comparison to dispersed catalytic center molecule (TOF value was enhanced by about 15 fold). OPV-Ru could selectively accumulate in the mitochondria of living cells. Benefiting from its inherent fluorescence, the dynamic distribution in cells and uptake behavior of OPV-Ru could be visualized under fluorescence microscopy. This work represents the first demonstration of a multifunctional organometallic complex catalyzing natural hydrogenation transformation in specific subcellular compartments of living cells with excellent performance, fluorescent imaging ability, specific mitochondria targeting and good chemoselectivity with high catalysis efficiency.

Iron-catalyzed oxidative mono- And bis-phosphonation of N,N-dialkylanilines

The dehydrogenative a-phosphonation of substituted N,N-dialkylanilines by dialkyl H-phosphonates was achieved under mild conditions by using environmentally benign iron(II) chloride as catalyst and teri-butyl hydroperoxide as oxidant. The reaction proceeded in the presence of electron-donating (methoxy, methyl, benzyl) and electron-withdrawing ring-substitutents (bromo, carbonyl, carboxyl, m-nitro) in moderate to good yields. The X-ray crystal structure of N-(5,5-dimethyl-2-oxo- 2lambda5-[1,3,2]dioxaphosphinan-2-yl-methyl)-N-methyl-p-toluidine was determined. Bis-(4-(dimethylamino)phe- nyl)methane and bis-4,4′- (dimethylamino)benzophenone underwent bisphosphonation selectively by respective monophosphonation at the remote dimethylamino groups. Furthermore, the use of excess dialkyl H-phosphonate and oxidant allowed us to functionalize both methyl groups of N(CH3)2 in N,N-dimethyl-p-toluidine and N,N-dimethylaminomesidine, respectively, to obtain alpha,alpha?- bisphosphonatoamines in high yield.

Improved simplicity and practicability in copper-catalyzed alkynylation of tetrahydroisoquinoline

Abstract: Alkynylation reactions of N-protected tetrahydroisoquinolines have been performed using several different protocols of cross dehydrogenative coupling. Initially, a CuCl-catalyzed method was investigated, which worked well with three different N-protecting groups, namely phenyl, PMP, and benzyl and t-BuOOH as oxidant in acetonitrile as solvent. The peroxide could then be replaced by simple air and acetonitrile for water, leading to an overall very environmentally friendly protocol. Finally, a decarboxylative alkynylation protocol starting from alkynoic acids was also developed using again air as oxidant. This avoids the use of gaseous alkynes in the introduction of short-chained alkyne substituents. Graphical abstract: [Figure not available: see fulltext.]
