Experimental evaluation of acute toxicity heterometalic new compounds – tartratogermanat cooper and zinc

Abstract

One of the possible ways of creating new drugs is aiming synthesis of compounds previously envisaged activity. Perspective in this area is to obtain complexes based on metal ions and ligands. Purpose: To establish toxikometric characteristics of new biologically active substances - tartratogermanat copper and zinc in the acute experiment. Materials and Methods: Studied acute toxicity in mice and rats under the conditions of oral (o), subcutaneous (s / c) and intraperitoneal (i / p) administration. The toxicity criterion of the test compounds was LD50, which was determined using the probit analysis method. In addition, a number of integrated toxicity indicators were calculated, in particular absolute toxicity, an acute toxic effect zone, a summary toxicity index and etc. The results: According to the results, the LD50 index of copper-tartratogermanate in mice was 36.88 mg / kg (i / p) 63.78 mg / kg (s / c) and 385.57 mg / kg (o); in rats - 78.16; 135.05 and794.26 m / kg, accordingly. The LD50 index of zinc-tartratogermanate in mice was 87.20 mg / kg (i / p) 167.05 mg / kg (s / c) and 1675.40 mg / kg (o); in rats - 141.57; 236.52 and 2792.45 μ / kg, accordingly. The new compound of zinc tartratogermanat belongs to low-toxic compounds (IV class of toxicity) in conditions of intraperitoneal, subcutaneous and oral administration in two animal species, in the same time-tartratogermanat copper is moderately toxic (toxicity class III). Zinc-containing compounds showed lower toxicity than similar compounds with cuprum. According to the resalts, the variability of the lethal doses for various routes of administration of copper tartrate-hommanate was 1.32-1.60 (in mice) and 1.66-1.92 (in rats) zinc tartrate-germanate, 1.31-1.50 (in mice) and 1.24-1.37 (in rats). Integral safety of the new BAС showes that compounds with zinc were more safety in oral take, while new compounds containing copper were the safest under conditions of injection. Conclusions: A small toxicity of new compounds tartratogermanat zinc and copper indicates the prospects for their further preclinical studies as potential drugs.a.
