Features of experimental modeling of tuberculosis in guinea pig with the participation of N'-(2-(5-((thephylline-7' yl)methyl)-4-R-1,2,4-triazole- ylthio)acethyl)isonicotinohydrazide

In this study, no toxic effects were detected after single subcutaneous injection of 40 mg/kg tadpoles. The results of macroand microscopic examination of the internal organs 14 days after single subcutaneous administration of N'-(2-(5-((thephylline-7'yl)methyl)-4-ethyl-1,2,4-triazole-3-ylthio)acethyl)isonicotino-hydrazide (GKP-305) at a dose of 20, 40 mg/kg showed the absence of any anatomical and morphological abnormalities in the tissue structures of the tentacles. The calculated value of the drug indicates a high degree of safety GKP-305 and its prospects for veterinary practice as an effective and safe tuberculocidal drug.
