title: [Modulation of glucocorticoid receptor interaction with non-steroidal drugs].
abstract: The Scatchard analysis of the specific binding of triamcinolone 3H-acetonide (TA-3HA) to Type II glucocorticoid receptors of cytosol from the liver of female Wistar rats weighing 180-200 g has shown that emoxipin at concentrations of 1 and 2 mM and analgin at concentrations of 5 and 10 mM reduce the density of glucocorticoid receptors and the association constant of a hormone-receptor complex. Analgin, 5 mM, increases the dissociation velocity constant of TA-3HA 5 times the effect of unlabeled triamcinolone acetonide. Emoxipin, 1 mM, produces the same effect on the receptor dissociation velocity constant of TA-3HA as the unlabeled triamcinolone acetonide. The Berke analysis has established that emoxipin and analgin reduce glucocorticoid receptor interactions by uncompetitive inhibition.
