Eliška Fučíková Evaluation of activity of potentional antifungal substances through the use of microdilution broth method II Diploma thesis Charles University in Prague, Faculty of Pharmacy in Hradec Kralove Specialist in laboratory methods Background: The aim of this thesis was to test substances with potential antifungal effect. We tested a totally 10 cathegories of substances: anilides of pyrazincarboxyl acid, arylaminopyrazines, pyrazin-2.3-dinitriles, pyrazincarboxyl acid esters, derivatives of (Z)-5-arylmethyliden-2-thioxothiazolidin-4-on, cholesterol and alkane acids esters, derivatives of thiosalicylamid , diamides, styrylbenzoxazoles, benzoxazepin-diones. Methods: The assesment was carried out using the microdilution broth method. Results: The most striking antifungal activity exhibit derivatives of thiosalicylamid for which MIC values were very low in almost all scale of concentration for all tested fungi. Conclusions: We found that the greatest antimycotic activity is manifested with the substitution of a halogen, mostly by chlorine
