(-)-N-{2-[(R)-3-(6,7-Dimethoxy-1,2,3,4-tetrahydroisoquinoline-2-carbonyl)piperidino]ethyl}-4-fluorobenzamide (YM758) is a novel inhibitor of the "funny" If current channel (If channel) that is expressed in the sinus node of heart and is being developed as a treatment for stable angina and atrial fibrillation. Its metabolites were identified in human urine, plasma, and feces by radio-high-perfor...

The mitochondria-associated endoplasmic reticulum (ER) membrane (MAM) is a small section of the outer mitochondrial membrane tethered to the ER by lipid and protein filaments. One such MAM protein is the σ-1 receptor, which contributes to multiple signaling pathways. We found that short interfering RNA-mediated knockdown of σ-1 reduced pregnenolone synthesis by 95% without affecting expression ...

The title compound, C(10)H(16)N(4), crystalizes with two mol-ecules (A and B) in the asymmetric unit in which the dihedral angles between the piperidine and pyrimidine rings are 47.5 (1) and 10.3 (1)°. The four C atoms of the pyrimidine ring in one of the mol-ecules are disordered over two sets of sites with occupancy factors 0.508 (11):0.492 (11). In the crystal, the A mol-ecules are linked to...

Marijuana and related drugs (cannabinoids) have been proposed as treatments for a widening spectrum of medical disorders. R(+)-[2, 3-dihydro-5-methyl-3-[(morpholinyl)methyl]pyrrolo[1,2,3-de]-1, 4-benzoxazin-yl]-(1-naphthalenyl)methanone mesylate (R(+)-WIN 55212-2), a synthetic cannabinoid agonist, decreased hippocampal neuronal loss after transient global cerebral ischemia and reduced infarct v...

The aim of this work was to improve the oral bioavailability of a recently discovered, novel structural class of 5-HT1A receptor agonists: aryl-{[4-(6-R-pyridin-2-ylmethyl)-amino]-methyl}-piperidin-1 -yl-metha none. Incorporation of a fluorine atom in the beta-position to the amino function in the side chain led to analogues that exhibited, in general, enhanced and long-lasting 5-HT1A agonist a...

Novel benzofuran-2-carboxamide ligands, which are selective for sigma receptors, have been synthesized via a microwave-assisted Perkin rearrangement reaction and a modified Finkelstein halogen-exchange used to facilitate N-alkylation. The ligands synthesized are the 3-methyl-N-phenyl-N-(3-(piperidin-1-yl)propyl)benzofuran-2-carboxamides (KSCM-1, KSCM-5 and KSCM-11). The benzofuran-2-carboxamide...

Behavioral studies of chronic CB(1) receptor activation may provide a pharmacological approach to understanding efficacy-related differences among CB(1) ligands as well as mechanistic commonalities between cannabinoid and noncannabinoid drugs. In the present studies, the effects of CB(1) agonists [(6aR,10aR)-3-(1-adamantyl)-6,6,9-trimethyl-6a,7,10,10a-tetrahydrobenzo[c]chromen-1-ol (AM411), 9β-...
