A simple and new methodology has been developed for the synthesis of novel bioactive pyrazolyl-isoxazoline hybrids from a pyrazolyl-substituted oxime and various substituted allyloxybenzenes, which are easily available, inexpensive starting materials. All the novel synthesized target hybrids were characterized by NMR, IR, and mass spectroscopic techniques. We have employed some of the hybrid materials in anti-bacterial and anti-fungal activity studies. The hybrid materials 6m and 6p exhibited the best anti-bacterial and anti-fungal activities.

A novel therapy that stimulates endogenous glucagon-like peptide-1 (GLP-1) secretion by Takeda G-protein-coupled receptor 5 (TGR5) agonists might be a superior alternative for the treatment of type 2 diabetes mellitus. A series of 4-phenoxythiazol-5-carboxamides were developed as highly potent TGR5 agonists using a bioisosteric replacement strategy based on the scaffold of 4-phenoxynicotinamides. The structure-activity relationship on the bottom phenyl ring and the thiazole ring was extensively studied, and the 2-methylthiazole derivatives 30c and e displayed the best in vitro potency toward human TGR5, with EC50 values of approximately 1 nM. While endowed with excellent in vitro potency, the 2-methyl-thiazoles were flawed with high microsomal clearance.

A series of 2-((5-aryloxy-1-methyl-3-methyl-1H-pyrazol-4-yl)methylene) hydrazinecarboxamides (6a-6l) and 2-((5-aryloxy-1-methyl-3-phenyl-1H-pyrazol-4-yl)methylene) hydrazinecarboxamides (7a-7l) were designed and synthesized. The maximal electroshock shock (MES) and subcutaneous pentylenetetrazole (sc-PTZ) seizure models in mice were used to evaluate the antiepileptic effect of compounds synthesized. Further, the acute neurotoxicity profile was also studied via the rotarod test. The results of sc-PTZ test indicate that a majority of compounds possessed anticonvulsant activity with long duration of protection effects. Among of them, compound 6k was found to be the most promising one, with an ED50 value of 20.4 mg/kg (in sc-PTZ model) and a PI value of 10.8, possessing higher anti-PTZ activity and wider safety margin than valproate and ethosuximide.
