- NOVEL ARYL OR HETEROARYL TRIAZOLONE DERIVATIVES OR SALTS THEREOF, OR PHARMACEUTICAL COMPOSITIONS COMPRISING THE SAME
-
The present technology provides aryl or heteroaryl triazolone derivatives or pharmaceutically acceptable salts thereof, preparation processes thereof, pharmaceutical compositions comprising the same, and the use thereof. The aryl or heteroaryl triazolone derivatives or their pharmaceutically acceptable salts exhibit selective inhibitory activity on VAP-1 and therefore can be usefully applied, e.g., for the treatment and prophylaxis of nonalcoholic hepatosteatosis (NASH).

- Design and synthesis of novel triazole antifungal derivatives by structure-based bioisosterism
-
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.

- Design, synthesis and antifungal evaluation of 1-(2-(2,4-difluorophenyl)-2- hydroxy-3-(1H-1,2,4-triazol-1-yl)propyl)-1H-1,2,4-triazol-5(4H)-one
-
Based on the structure of the active site of cytochrome P450 14α-demethylase (CYP51) and the conclusions of the structure-activity relationships of azole antifungals, a series of 1-(2-(2,4-difluoro-phenyl)-2- hydroxy-3-(1H-1,2,4-triazol-1-yl)propyl)-1H-1,2,4-triazol-5(4H)-one of fluconazole analogs was synthesized. All compounds were characterized by IR, HRMS, 1HNMR and 13C NMR spectroscopic analysis. Results of preliminary antifungal in vitro test using eight human pathogenic species showed that some compounds displayed comparable or even better antifungal activities than reference drug fluconazole and that compound 3i exhibited significant activity against Candida albicans being worthy of further optimization.

- Total synthesis of (2R,4S,2′S,3′R)-hydroxyitraconazole: Implementations of a recycle protocol and a mild and safe phase-transfer reagent for preparation of the key chiral units
-
A convergent total synthesis of enantiomerically-pure (2R,4S,2′S, 3′R)-hydroxyitraconazole 1b is described. The left dioxolane portion of the molecule was prepared in good yield by the conversion of (S)-10 to the corresponding enantiomerically and diastereomerically-pure acetonide (2R,4R)-3 by a recycle protocol involving diastereoselective crystallization of the tosylate salt, followed by re-equilibration of the mother liquor and crystallization. The right-hand triazolone moeity (2S,3R)-4 was generated by alkyaltion of triazolone 6 with enantiomerically pure cyclic sulfate (4R,5R)-7 under mild and essentially non-hazardous reaction conditions (TDA-1, K 2CO3, acetonitrile).
