Six structural motifs based on the initial (lead) structure of merbarone were designed, prepared, and tested against the glioblastoma LN-229 cell line. Three different structural moieties were modified in the search for optimal glioblastoma activity: the 1,3-diazinane moiety, the aryl moiety, and the heteroatom linker. Calculated molecular descriptors such as lipophilicity (C log P), acidic strength (calculated pKa), and polar surface area (PSA) were used to design a diverse structural library of these compounds. From six different structural motifs and 136 compounds, a handful of examples with moderate (100 μg/ml), good (10 μg/ml) and excellent (1 μg/ml) glioblastoma activity were elucidated.

The incidence of life-threatening fungal infections is increasing dramatically. In an attempt to develop novel antifungal agents, our previously synthesized phenoxyalkylpiperazine triazole derivatives were used as lead structures for further optimization. By means of structure-based bioisosterism, triazolone was used as a new bioisostere of oxygen atom. This type of bioisosteric replacement can improve the water solubility without loss of hydrogen-bonding interaction with the target enzyme. A series of triazolone-containing triazoles were rationally designed and synthesized. As compared with fluconazole, several compounds showed higher antifungal activity with broader spectrum, suggesting their potential for further evaluations.
