Recently, the fungal sphingolipid glucosylceramide (GlcCer) synthesis has emerged as a highly promising new target for drug discovery of next-generation antifungal agents, and we found two aromatic acylhydrazones as effective inhibitors of GlcCer synthesis based on HTP screening. In the present work, we have designed libraries of new aromatic acylhydrazones, evaluated their antifungal activities (MIC80 and time-kill profile) against C. neoformans, and performed an extensive SAR study, which led to the identification of five promising lead compounds, exhibiting excellent fungicidal activities with very large selectivity index. Moreover, two compounds demonstrated broad spectrum antifungal activity against six other clinically relevant fungal strains. These five lead compounds were examined for their synergism/cooperativity with five clinical drugs against seven fungal strains, and very encouraging results were obtained; e.g., the combination of all five lead compounds with voriconazole exhibited either synergistic or additive effect to all seven fungal strains.

A series of pyrazolyl-acylhydrazone derivatives (1e-20e) have been designed and synthesized and their biologic activities were also evaluated for telomerase inhibition and tumor cell antiproliferation. Among all the compounds, 12e showed the most potent activity in vitro, which inhibited the growth of MCF-7 and B16-F10 cell lines with IC50 values of 0.57 ± 0.03 and 0.49 ± 0.07 μM, respectively. Compound 12e also exhibited significant telomerase inhibitory activity (IC50 = 1.9 ± 0.43 μM). The result of flow cytometry demonstrated that compound 12e induced cell apoptosis. Docking simulation was performed to insert compound 12e into the crystal structure of telomerase at ATP binding site to determine the probable binding model. Based on the preliminary results, compound 12e with potent inhibitory activity in tumor growth may be a potential anticancer agent.
