- Design, synthesis, and in vitro evaluation of novel triazole analogues featuring isoxazole moieties as antifungal agents
-
In order to develop novel antifungal agents, based on our previous work, a series of (2R,3R)-3-((3-substitutied-isoxazol-5-yl)methoxy)-2-(2,4-difluorophenyl)-1-(1H-1,2,4-triazol-1-yl) butan-2-ol (a1-a26) were designed and synthesized. All of the compounds exhibited good in vitro antifungal activities against eight human pathogenic fungi. Among them, compound a6 showed excellent inhibitory activity against Candida albicans and Candida parasilosis with MIC80 values of 0.0313 μg/mL. In addition, compounds a6, a9, a12, a13 and a14 exhibited moderate inhibitory activities against fluconazole-resistant isolates with MIC80 values ranging from 8 μg/mL to 16 μg/mL. Furthermore, compounds a6, a12 and a23 exhibited low inhibition profiles for CYP3A4. Clear SARs were analyzed, and the molecular docking experiment was carried out to further investigate the relationship between a6 and the target enzyme CYP51.

- Design, synthesis, and in vitro evaluation of novel antifungal triazoles
-
Twenty-nine novel triazole analogues of ravuconazole and isavuconazole were designed and synthesized. Most of the compounds exhibited potent in vitro antifungal activities against 8 fungal isolates. Especially, compounds a10, a13, and a14 exhibited superior or comparable antifungal activity to ravuconazole against all the tested fungi. Structure-activity relationship study indicated that replacing 4-cyanophenylthioazole moiety of ravuconazole with fluorophenylisoxazole resulted in novel antifungal triazoles with more effectiveness and a broader-spectrum.

- Synthesis and biological evaluation of aryl isoxazole derivatives as metabotropic glutamate receptor 1 antagonists: A potential treatment for neuropathic pain
-
Glutamate is the major excitatory neurotransmitter and known to activate the metabotropic and ionotropic glutamate receptors in the brain. Among these glutamate receptors, metabotropic glutamate receptor 1 (mGluR1) has been implicated in various brain disorders including anxiety, schizophrenia and chronic pain. Several studies demonstrated that the blockade of mGluR1 signaling reduced pain responses in animal models, suggesting that mGluR1 is a promising target for the treatment of neuropathic pain. In this study, we have developed mGluR1 antagonists with an aryl isoxazole scaffold, and identify several compounds that are orally active in vivo. We believe that these compounds can serve as a useful tool for the investigation of the role of mGluR1 and a promising lead for the potential treatment of neuropathic pain.

- Oxime Carbamate-Discovery of a series of novel FAAH inhibitors
-
A series of novel oxime carbamates have been identified as potent inhibitors of the key regulatory enzyme of the endocannabinoid signaling system, fatty acid amide hydrolase (FAAH). In this Letter, the rationale behind the discovery and the biological evaluations of this novel class of FAAH inhibitors are presented. Both in vitro and in vivo results of selected targets are discussed, along with inhibition kinetics and molecular modeling studies.1.

- Potent inhibitors of lipoprotein-associated phospholipase A2: Benzaldehyde O-heterocycle-4-carbonyloxime
-
A series of multi-substituted oximes were prepared and their potencies for inhibiting lipoprotein-associated phospholipase A2 (Lp-PLA2) activity were evaluated in vitro. Among them, compounds 3a, 3b, and 3m were identified to display a micromolar potency for inhibiting Lp-PLA2 in whole human plasma and isolated human LDL. Based on these results, structure-activity relationship was studied on modification of three parts of R1, R2, and R3 to identify a potent pharmacophore for Lp-PLA2. In an attempt to introduce various functional groups at R2 and R3, we discovered that replacement of less lipophilic groups led to an increase of inhibitory activity. Among the tested oxime derivatives, cyano- and morpholino-substituted analogue 4f at R2 and R3 had the highest potency with an IC50 value of 0.05 μM in whole human plasma.
