Factors affecting binding of trans-N-[2-(methylamino)cyclohexyl]benzamides at the primary morphine receptor
摘要:
In this paper, we describe the synthesis of a series of trans-N-[2-(methylamino)cyclohexyl]benzamides possessing morphine-like pharmacological properties. The affinity of the compounds for the agonist and antagonist states of the mu opioid receptor has been established by means of an in vitro binding assay. We have investigated the geometry and electronic structure of the molecules using molecular mechanics and an ab initio SCF-MO procedure with FSGO basis sets. Comparison to naloxone reveals properties of possible importance in receptor association. We have considered both the S,S and R,R isomers in the binding model. Statistical analyses imply that three factors play a significant role in binding: (1) membrane-water partitioning, (2) the capacity of the aromatic ring and amine N-substituent to act as electron acceptors, (3) the conformational energy required to attain the binding configuration.

The application relates to a compound of Formula (I') or (I), or a pharmaceutically acceptable salt, hydrate, solvate, prodrug, stereoisomer, or tautomer thereof, which modulates the activity of thyroid hormone receptors, a pharmaceutical composition comprising a compound of Formula (I') or (I), and a method of treating or preventing a disease or disorder regulated by thyroid hormone.
Antibodies, immunoassay methods and kits for the detection and determination of 3,4,-dichloro-N-[2-(dimethylamino)cylohexyl]-N-methylbenzamide and 3,4,-dichloro-N-[2-(methylamino)cylohexyl]-N-methylbenzamide, as well as the precursory immunogens, are described.
Substituted naphthalenyloxy- or naphthalenylthiooxyamides of trans-1,2-diaminocyclohexanes possess selective kappa opioid receptor site binding activity and are thus useful as analgesic or diuretic agents. Methods of preparing the compounds, pharmaceutical compositions, and a method for their use as analgesic agents are also disclosed.

direction to develop new and fundamental catalysis. For the appealing yet flexible π-face activation, can two or more π-acidic surfaces be manipulated for cooperative activation to achieve efficient transformation and particularly selectivity control is highly desirable. Here, we demonstrate a supramolecular π-catalysis strategy by establishing cooperative π-face activation in a confined electron-deficient

substituents were the most potent with comparable EC50 values for inhibition of cAMP accumulation; 26.49 ± 11.2 nmol L-1 and 8.8 ± 4.9 nmol L-1, respectively. Despite similar potencies for Gαi coupling, these two compounds had strikingly different hMOR internalization efficacies: U-47700 (10 μmol L-1) induced ~25% hMOR internalization similar to DAMGO while AH-7921 (10 μmol L-1) induced ~5% hMOR internalization
