Ecological Systems and Devices Annotation << Back The synthesis and antimicrobic activity 3 aryl (methyl) 5 nitro methyl 1,2,4,- oxidiazoles hydrazones nitro 1,2,4-oxidiazol-5-carbaldegid Kalyamina A.V., Tyrkov A.G. A series 3 aryl (methyl) 5 nitro methyl 1,2,4,- oxidiazoles and them nitrohydrozone derivative was synthesized. Their antimicrobic activity were investigated. The relation «structure – activity» was revealed and the acute diurnal toxicity wes determined.
