In this study, a series of novel thiazol-2(3H)-imine (2a-2j) were designed, synthesized, and characterized by means of 1H NMR, 13C NMR, and HRMS spectral analyses. In vitro antifungal activity was performed using a modified EUCAST protocol. Two of the synthesized compounds (2d and 2e) showed activity against Candida albicans and Candida parapsilosis. Compound 2e showed activity against C. parapsilosis (MIC50 = 1.23 μg/mL) for 48 h. This value is very similar to ketoconazole. The dynamic analysis of the potential compounds 2d and 2e revealed notable stability while interacting with the 14α-demethylase enzyme substrate. The absorption, distribution, metabolism, and excretion (ADME) studies of the candidate compound showed acceptable ADME parameter data and verified their drug-likeness characteristics. According to the results of this study, compound 4-(4-fluorophenyl)-N-(3-morpholinopropyl)-3-phenylthiazol-2(3H)-imine (2e) and its derivatives as 14α-demethylase inhibitors can be used as a new antifungal for further structural improvements and additional research.
