Structure-activity relationship of etomidate derivatives at the GABA(A) receptor: Comparison with binding to 11beta-hydroxylase.
نویسندگان
چکیده
At the GABA(A) receptor, low concentrations of etomidate potentiate the inhibitory effect of GABA on specific binding of the closed channel ligand [(3)H]ethynylpropylbicycloorthobenzoate ([(3)H]EBOB). Here, we present SARs for etomidate and structurally related compounds inducing this effect. In the absence of GABA, similar SARs, but 14-20 times weaker potencies were observed. We discuss these SARs in comparison to the much higher potencies of these compounds as inhibitors of 11beta-hydroxylase.

New selective inhibitors of steroid 11beta-hydroxylation in the adrenal cortex. Synthesis and structure-activity relationship of potent etomidate analogues.
Derivatives of etomidate were evaluated as inhibitors of adrenal steroid 11beta-hydroxylations. Stereoselective coupling by Mitsunobu produced chirally pure analogues to study the effect of configuration, modification of the ester, and substitution in the phenyl ring, with the aim to probe specific sites for introducing a radionuclide. Iodophenyl metomidate (IMTO) labeled with iodine-131 served...
متن کاملIn-silico Investigation of Tubulin Binding Modes of a Series of Novel Antiproliferative Spiroisoxazoline Compounds Using Docking Studies
Interference with microtubule polymerization results in cell cycle arrest leading to cell death. Colchicine is a well-known microtubule polymerization inhibitor which does so by binding to a specific site on tubulin. A set of 3',4'-bis (substituted phenyl)-4'H-spiro[indene-2,5'-isoxazol]-1(3H)-one derivatives with known antiproliferative activities were evaluated for their tubulin binding modes...

متن کاملQuantitative structure-activity relationship (QSAR) study of CCR2b receptor inhibitors using SW-MLR and GA-MLR approaches
In this paper, the quantitative structure activity-relationship (QSAR) of the CCR2b receptor inhibitors was scrutinized. Firstly, the molecular descriptors were calculated using the Dragon package. Then, the stepwise multiple linear regressions (SW-MLR) and the genetic algorithm multiple linear regressions (GA-MLR) variable selection methods were subsequently employed to select and implement th...
