The piperidine ring of the title compound, C(13)H(13)Cl(2)NO, adopts an envelope conformation. Inter-molecular C-H⋯O inter-actions link the mol-ecules into a C(7) chain running along the b axis.

As part of a comprehensive program to discover α9α10 nicotinic acetyl-choline receptor antagonists, the title compounds C30H36N2, (I), and C36H48N2, (II), were synthesized by coupling 4,4'-bis-(3-bromo-prop-1-yn-1-yl)-1,1'-biphenyl with 4-methyl-piperidine and 2,2,6,6-tetra-methyl-piperidine, respectively, in aceto-nitrile at room temperature. In compound (I), the biphenyl system has a twisted ...

In solid-phase peptide synthesis, the nominal batch size is calculated using the starting resin substitution and the mass of the starting resin. The starting resin substitution constitutes the basis for the calculation of a whole set of important process parameters, such as the number of amino acid derivative equivalents. For Fmoc-substituted resins, substitution determination is often performe...

In the title compound, C(13)H(17)ClN(2)O, the piperidine ring adopts a chair conformation and the N atom in that ring is close to pyramidal (bond angle sum = 357.5°). In the crystal, mol-ecules are linked into C(4) chains propagating in [010] by N-H⋯O hydrogen bonds.

In the title compound, C(13)H(16)N(2)OS, the piperidine ring exhibit a classical chair conformation. In the crystal, the mol-ecules are linked by N-H⋯O hydrogen bonds, forming zigzag chains running parallel to the c axis.

In the structure of the title compound, C(12)H(14)N(2)O(3), the piperidine ring adopts a chair conformation and the aryl substitutent occupies an equatorial position.

cule-1 (ICAM-1), E-selectin and vascular cell adhesion molecule-1 (VCAM-1), play a pivotal role in the inflammatory and immunological responses. They are initially upregulated on the endothelium by tumor necrosis factor-a (TNF-a) or interleukin-1 (IL-1) and go on to mediate the steps of leukocyte migration from the vasculature into the inflamed tissue, these leukocytes then promote the inflamma...

The synthesis and monoamine transporter activity of additional members of a series of 3,4-disubstituted piperidines (truncated analogues of the WIN series) are described. All members of this series were prepared from arecoline hydrobromide in optically pure form and were evaluated for their ability to inhibit high affinity uptake of dopamine (DA), serotonin (5-HT) and norepinephrine (NE) into r...

Phencyclidine (1-(1-phenylcyclohexyl) piperidine, PCP, I) and ketamine (2-O-chlorophenyl-2-methylaminocyclohexan, II) have shown analgesic effects. Some of its derivatives were synthesized and their biological properties have been studied. In this study, a new derivative of PCP, (1-[1-(3-methoxyphenyl) (tetralyl)] piperidine, PCP-OCH3-tetralyl, III) was synthesized and the acute thermal pain ...
