piperidine/dental caries

A series of 4-(N,N-diarylamino)piperidines are synthesized and evaluated for high affinity binding and selectivity to the delta-opioid receptor using a combination of 3D-QSAR and molecular docking techniques. Based on experimental ligand binding data to both mu- and delta- opioid receptors, CoMFA

The binding of a moderate inhibitor, 3'-N-piperidine-4-carboxyl-3'-deoxy-ara-uridine, to ribonuclease A has been studied by X-ray crystallography at 1.7A resolution. Two inhibitor molecules are bound in the central RNA binding cavity of RNase A exploiting interactions with residues from peripheral

Five N'-alkyl-N-(2-aminoethyl)piperidines were synthesized and their in vitro antimicrobial activities were tested against four micro-organisms related to dental caries (Streptococcus mutans, S. sobrinus, Actinomyces viscosus, and A. naeslundii) which are known to be implicated in dental caries. The

Anaplastic lymphoma kinase (ALK) has gained increased attention as an attractive therapeutic target for the treatment of various cancers, especially non-small-cell lung cancer (NSCLC). Recently, piperidine carboxamides were reported as Type I1/2 inhibitors of ALK, which occupy both the ATP binding

In the preceding paper we reported on a docking study with the SYSDOC program for predicting the binding sites of huperzine A in acetylcholinesterase (AChE) [Pang, Y.-P. and Kozikowski, A.P., J. Comput.-Aided Mol. Design, 8 (1994) 669]. Here we present a prediction of the binding sites of

The synthesis of highly substituted piperidine from the one-pot reaction between aromatic aldehydes, anilines and β-ketoesters in the presence of tartaric acid as a catalyst has been investigated in both methanol and ethanol media at ambient temperature. Different conditions of temperature and

The 2.5 Angstrum structure of bovine epsilon-thrombin in complex with N alpha-2-naphthyl-sulfonyl-L-3-amidinophenylalanyl-4-methylpiper idide (L-NAPAMP) was solved and crystallographically refined to an R-value of 0.19. The L-NAPAMP moiety is completely and unambiguosly defined in the electron

Depression is a critical mood disorder that affects millions of patients. Available therapeutic antidepressant agents are associated with several undesirable side effects. Recently, it has been shown that Neurokinin 1 receptor (NK1R) antagonists can potentiate the antidepressant effects of

Amantadine has been used for decades as an inhibitor of the influenza A virus M2 protein (AM2) in the prophylaxis and treatment of influenza A infections, but its clinical use has been limited by its central nervous system (CNS) side effects as well as emerging drug-resistant strains of the virus.

The primary quorum sensing system in the opportunistic pathogen Pseudomonas aeruginosa is regulated through the synthesis and secretion of N-3-oxo-dodecanoyl-L-homoserine lactone (C12) which binds the transcriptional activator LasR. In this study we report the design, synthesis and biological

The γ-aminobutyric acid (GABA) transporter GAT1 is involved in GABA transport across the biological membrane in and out of the synaptic cleft. The efficiency of this Na⁺ coupled GABA transport is regulated by an electrochemical gradient, which is directed

Soft molecular host frameworks made of the hydrogen-bonded metal complex (MC) Co(NH3)(6)3+ and 4,4'-biphenyldisulfonate (BPDS) include different guest molecules to form inclusion compounds of the type (MC)2(BPDS)3.n(guest). Structurally characterized were six compounds with guest molecules of DMSO,

Red cell water volumes were measured using ESR methods during transient osmotic perturbation, and under equilibrium conditions. Cell water contents were determined using the spin label Tempone (2,2,6,6-tetramethyl piperidine-N-oxyl) and the membrane impermeable quencher potassium chromium oxalate.

Dahl salt-sensitive (DS) rats fed high-salt diet exert compensated left ventricular (LV) hypertrophy and eventually develop heart failure. Oxidative stress has been shown to be involved in myocardial remodeling and failure and thus might play an important role in this transition from hypertrophy to

Host-guest binding sometimes triggers the subsequent chemical reactions of the host framework as well as changes in the physical properties. Since the host-guest binding generally occurs very quickly, it is sometimes difficult to differentiate the mechanism from the alternative one in which the
