[Glucocorticoid receptors as targets for pharmacologic action].

Experimental data demonstrate the influence of certain drugs on the interaction of Type II and III glucocorticoid receptors of the liver cytosol and labelled natural and synthetic glucocorticoids. Preparations of the phenothiazine (aminazine, tizercine) and pyrazolone (amidopyrine, analginum) series and non-steroid anti-inflammatory drugs (acetylsalicylic acid, sodium salicylate) exert a significant effect on the glucocorticoid-receptor interplay. Certain drugs (tizercine, analginum) have an anti-stress effect by lowering the level of Type II glucocorticoid receptors of liver cytosol and corticosterone concentration in the blood plasma of rats. The phenothiazine and no-spa derivatives inhibit the matrix activity of the thymocyte DNA in adrenalectomized rats. Pyracetam, caffeine, adrenaline, noradrenaline, verapamil, digoxin, and streptomycin do not influence the thymocyte DNA matrix activity in the presence of triamcinolone acetonide. Based on the literature data and original research findings, the problem of glucocorticoid receptors employment as targets for medication to control the glucocorticoid effect and stress is discussed.
