Микробиологические испытани показывают , что полученные халконы обладают высоким антибактериальным действием на модели различных стафилококков. Бумажные диски, содержащие равные навески (в мкг) халконов и антибиотиков (пенициллина , стрептомицина, неомицина), дают в экспериментах равные зоны задержки роста стафилококка 209-Р и золотистого гемолитического стафилококка, выделенного от больного. Указанные халконы не оказывают губительного действи на кишечную микрофлору.Microbiological tests show that the obtained chalcones have a high antibacterial effect on models of various staphylococci. Paper disks containing equal weights (in mcg) of chalcones and antibiotics (penicillin, streptomycin, neomycin) give in experiments equal zones of growth inhibition of staphylococcus 209-P and golden hemolytic staphylococcus isolated from the patient. These chalcones do not have a detrimental effect on the intestinal microflora.
Остра токсичность у1казанных халконов определ етс на трех видах лабораторных животных: л гушках, белых мышах и белых крысах. Вводились препараты per OS и подкожно в виде водной суспензии или раствора в диметилсульфоксиде. Контрольна сери опытов позвол ет изучить вли ние тех же количеств диметилсульфоксида и тех же путей введени , какие берутс при использовании его как растворител халконов. При испытании остройThe acute toxicity of these chalcones is determined by three types of laboratory animals: animals, white mice and white rats. Drugs were administered per OS and subcutaneously in the form of an aqueous suspension or solution in dimethyl sulfoxide. A control series of experiments allows to study the effect of the same amounts of dimethyl sulfoxide and the same routes of administration that are taken when using it as a chalcone solvent. When experiencing acute

The acute toxicity of 2,2,4-trioxy-5-bromchalcone was also tested on white rats. When subcutaneously administered 2, (2,4-trioxy-3,5,5-tribromhalkona acute toxicity LDso 60 mg / kg, LDioo 100 mg / kg.
При введении 2 г/кг указанных халконов per OS смертельных исходов не наблюдалось . В сери х с определением хронической, токсичности летальности не было.With the introduction of 2 g / kg of these chalcones per OS, no deaths were observed. In the series with the definition of chronic toxicity, lethality was not.
