Six amidrazone derivatives were synthesized. Their structure was determined using modern analytical methods (TLC, mass spectrometry, elemental analysis, ¹H NMR spectrometry and infrared spectroscopy). As starting compounds for the preparation of substituted amidrazones hydrazonoyl chlorides commercially available compounds were used. Computer program PASS (Prediction of Activity Spectra for Substances) has been applied for prediction of biological activity spectra of synthetic substances with the aim to discover their pharmacological potential. Computer-aided prediction of interaction amidrazone derivatives with protein targets was carried out with specialized version of the computer program PASS - PASS Targets. Open- source program AutoDock Vina was used for docking of amidrazones to crystal structures of targets: Candida albicans glucan 1,3-β-glucosidase (PDB code 2PB1), Candida albicans ATP-dependent molecular chaperone HSP82 (PDB code 2IWX), Staphylococcus aureus dehydrosqualene synthase (PDB code 3ACX), Bacillus subtillis 4'-phosphopantetheinyl transferase sfp (PDB code 1QR0) and Escherichia coli cystathioninebeta-lyase metC (PDB code 1CL2). Antimicrobial activity was studied by two-fold serial dilutions of the sample in the meat-broth and Sabouraud medium. As a test cultures microorganisms were used: Staphylococcus aureus АТСС 6538-Р, Bacillus cereus ATCC 6633, Escherichia coli АТСС 25922, Candida albicans NCTC 885-653, Aspirgillus niger ATCC 9642. The resulting compounds showed a potation antimicrobial activity.
