Synthesis and pharmacological evaluation of 2-(3-piperidyl)-1,2,3,4-tetrahydroisoquinoline derivatives as specific bradycardic agents.

Novel 1,2,3,4-tetrahydroisoquinoline derivatives bearing directly a cyclic amine at the 2-position were prepared and examined for their bradycardic activities in isolated right atria and in anesthetized rats. The structure-activity relationships (SAR) study revealed that the 2-(3-piperidyl)-1,2,3,4-tetrahydroisoquinoline skeleton is essential for the appearance of potent in vitro activity, and that the presence of at least one methoxy group at the 6- or 7-position of the 1,2,3,4-tetrahydroisoquinoline ring is important to exert potent in vitro activity. In vivo tests of selected compounds demonstrated that 2-(1-benzyl-3-piperidyl)-6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline (6c) exhibited potent bradycardic activity with negligible influence on mean blood pressure in rats, although its potency is a half of that of Zatebradine.

Construction of donor-acceptor type conjugated microporous polymers: A fascinating strategy for the development of efficient heterogeneous photocatalysts in organic synthesis

Metal-free, visible-light driven, solid organic photocatalysts provide a more green and environmentally friendly alternative to traditional metal-based photocatalysts. Donor-Acceepor (D-A) dyads possess a feature of easy to adjust the photoelectric properties, and enhance their photocatalytic performances. Here we report a fascinating strategy for screening excellent organic porous photocatalysts through oxidative coupling of single D-A based monomer, which has still an important advantage to ensure uniformity of polymer structure except for the inherent characteristics of D-A polymers. According to this strategy, three D-A typed conjugated microporous polymer (DA-CMP) photocatalysts consisting of alternating electron-rich (carbazole) and electron-deficient (benzene, 4,7-diphenyl-2,1,3-benzothiadiazole or anthraquinone) units have been synthesized, and their porosity and photoelectric properties including adsorption, emission, lifetime, optical bandgaps, energy levels and transient photocurrent response as well as photocatalytic activity, were conveniently tuned by selecting different D-A monomers with tunable electron-deficient moiety. These DA-CMPs were exploited as metal-free photocatalysts in the oxidative C-H functionalization reactions in the presence of visible-light and molecular oxygen. They showed excellent photocatalytic activity, extensive substrate adaptability and outstanding reusability, due to combining some key features like permanent porosity, outstanding stability and optoelectronic properties. In addition, the reaction mechanism for DA-CMP photocatalyzed C-H functionalization reactions under visible-light irradiation was investigated in detail. Moreover, to prove in depth the benefits of the heterogeneous photocatalysis, a continuous flow procedure has been conducted with an excellent yield.

CBr4-mediated cross-dehydrogenative coupling reaction of amines

A novel CBr4-mediated dehydrogenative Povarov/aromatization tandem reaction of glycine derivatives with alkenes, leading to complex quinoline derivatives, and a CBr4-mediated dehydrogenative C?H functionalization of N-aryl tetrahydroisoquinolines with nucleophiles to form C?C and C?P bonds are reported. The reactions were performed under very simple and mild reaction conditions; only CBr4 was used as a promoter. A plausible mechanism involving a radical process is proposed.

Drug-induced modifications of the immune response. I. Substituted 1-phenylisoquinolines

A series of 1-phenylisoquinolines and related compounds was prepared and tested for potential antiallergic activity. Several compounds of this series inhibited the antigen-induced wheal formation in rat passive cutaneous anaphylaxis (PCA) assay, a commonly used test for antiallergic activity. Many of these compounds also inhibited the antigen-induced histamine release from passively sensitized guinea pig lung slices. Furthermore, almost all of these derivatives inhibited the cyclic nucleotide phosphodiesterase, suggesting this as one of several possible mechanisms of action.

Structure-based design of new dihydrofolate reductase antibacterial agents: 7-(benzimidazol-1-yl)-2,4-diaminoquinazolines

A new series of dihydrofolate reductase (DHFR) inhibitors, the 7-(benzimidazol-1-yl)-2,4-diaminoquinazolines, were designed and optimized for antibacterial potency and enzyme selectivity. The most potent inhibitors in this series contained a five-membered heterocycle at the 2-position of the benzimidazole, leading to highly potent and selective compounds that exploit the differences in the size of a binding pocket adjacent to the NADPH cofactor between the bacterial and human DHFR enzymes. Typical of these compounds is 7-((2-thiazol-2-yl)benzimidazol-1-yl)-2,4 diaminoquinazoline, which is a potent inhibitor of S. aureus DHFR (Ki = 0.002 nM) with 46700-fold selectivity over human DHFR. This compound also has high antibacterial potency on Gram-positive bacteria with an MIC versus wild type S. aureus of 0.0125 mug/mL and a MIC versus trimethoprim-resistant S. aureus of 0.25 mug/mL. In vivo efficacy versus a S. aureus septicemia was demonstrated, highlighting the potential of this new series.

Two series of sandwich frameworks based on two different kinds of nanosized lanthanide(III) and copper(I) wheel cluster units

Two series of sandwich frameworks, [La6(mu3-OH) 2(ox)3L12Cu11(mu3-X) 6(mu2-X)3]¡Á8 H2O (X=Br/Cl, FJ-21 a/b; L=4-pyridin-4-yl-benzonate; ox=oxalate) and [Ln4(OAc) 3(H2O)4L9][Cu(mu3-I)] @Cu10(mu3-I)(mu4-I)6(mu 5-I)3]¡Á7H2O (Ln=Pr/Nd/ Sm/Eu, FJ-22 a/b/c/d; OAc=acetate) have been hydrothermally prepared. These sandwich frameworks are assembled by two different kinds of nanosized lanthanide(III) and copper(I) wheel cluster units, La18 and 3Cu@Cu24 in FJ-21, Ln24 and Cu2@Cu24 in FJ-22. The synergistic coordination between organic ligands, L and oxalate/acetate, leads to the formation of La18 and Ln24 wheels, while the synergistic coordination between organic L and inorganic Br/I ligands results in 3Cu@Cu24 and Cu2@Cu24 wheels for FJ-21 and FJ-22, respectively. Thus, two types of synergistic coordination between two different organic ligands, as well as inorganic and organic ligands are simultaneously observed in FJ-21 and FJ-22. Synergistic coordination: Two types of synergistic coordination between organic 4-pyridin-4-yl-benzonate and oxalate/acetate ligands, as well as organic 4-pyridin-4-yl-benzonate and inorganic Br/I ligands were simultaneously observed in two series of sandwich frameworks based on linkages of two distinct layered networks of nanosized LnIII and CuI wheels, La18/3Cu@Cu24 in FJ-21 and Ln24/Cu2@Cu24 in FJ-22, by 4-pyridin-4-yl-benzoate ligands (see figure).

Synthesis and angiotensin converting enzyme-inhibitory activity of N- [(1S)-1-carboxy-5-(4-piperidyl)pentyl]-L-alanine derivatives

As part of a search for potent and long-lasting angiotensin converting enzyme (ACE) inhibitors, various types of N-[(1S)-1-carboxy-5-(4- piperidyl)pentyl]-L-alanine derivatives (7a, 8-11) were prepared. The key synthetic intermediate, N-[(1S)-5-(1-benzyloxycarbonyl-4-piperidyl)-1- ethoxycarbonylpentyl]-L-alanine (17a), was synthesized by asymmetric reduction of the alpha-oxoester (13) with Lactobacillus paracasei subsp. paracasei followed by a substitution reaction with tert-butyl L-alanine (15) and subsequent treatment with hydrogen chloride. Compounds 7a and 8-11 showed potent and long-lasting ACE-inhibitory activity in rats.
