Synthetic cannabinoids, as exemplified by SDB-001 (1), bind to both CB1 and CB2 receptors and exert cannabimimetic effects similar to (-)-trans-Δ9-tetrahydrocannabinol, the main psychoactive component present in the cannabis plant. As CB1 receptor ligands were found to have severe adverse psychiatric effects, increased attention was turned to exploiting the potential therapeutic value of the CB2 receptor. In our efforts to discover novel and selective CB2 receptor agonists, 1 was selected as a starting point for hit molecule identification and a class of 1H-pyrazole-3-carboxamide derivatives were thus designed, synthesized, and biologically evaluated. Systematic structure-activity relationship investigations resulted in the identification of the most promising compound 66 as a selective CB2 receptor agonist with favorable pharmacokinetic profiles. Especially, 66 treatment significantly attenuated dermal inflammation and fibrosis in a bleomycin-induced mouse model of systemic sclerosis, supporting that CB2 receptor agonists might serve as potential therapeutics for treating systemic sclerosis.

Five luminescent europium (III) carboxylate complexes have been synthesized by using ligand 3-isopropylpyrazole-5-carboxylic acid as primary ligand and 4,4’-dimethyl-2,2’-bipyridyl, 2,2’-bipyridyl, 5,6-dimethyl-1,10-phenanthroline and 1,10-phenanthroline as secondary ligands and characterized through various techniques. These complexes exhibit excellent thermal stability and characteristic europium centered photoemission spectra under the excitation of ultraviolet light. Luminescence decay curves, Judd–Ofelt analysis, internal quantum efficiency and energy transfer mechanism have also been discussed. The color coordinates and color purity are calculated to investigate red emission of the complexes. The study results reveal that these complexes can be potentially used as red light emitting materials in various optoelectronic devices.

A green, simple and highly efficient method for the synthesis of pyrazole-3-carboxylates and 3,5-disubstituted pyrazoles by cyclization of 4-aryl(hetaryl, alkyl)-2,4-diketoesters and 1,3-diketones with semicarbazide hydrochloride under on water conditions has been developed. This method also does not require toxic hydrazine and product purification, eliminating the use of toxic liquid chemicals.

Cascade regioselective synthesis of pyrazoles from nitroallylic acetates and N-tosyl hydrazine
Shao, Nana,Chen, Tong,Zhang, Taotao,Zhu, Huajian,Zheng, Qunxiong,Zou, Hongbin
, p. 795 - 799 (2014/01/23)
A simple, practical, and regioselective synthetic protocol for the formation of pyrazoles was developed. Unlike all other previously reported reactions of nitroallylic acetates, this process was initiated by a S N2 reaction at the electrophilic γ site. A plausible mechanism for the cascade SN2-Michael synthesis is proposed.
Highly regioselective organocatalyzed synthesis of pyrazoles from diazoacetates and carbonyl compounds

A general, organocatalytic inverse-electron-demand [3+2] cycloaddition reaction between a range of carbonyl compounds and diazoacetates has been developed. This reaction is catalyzed by secondary amines as a "green promoter" to generate substituted pyrazoles with high levels of regioselectivity. It is noteworthy that this [3+2] cycloaddition reaction proceeds efficiently at room temperature with a simple and inexpensive catalyst. Considering the large variety and ready availability of the starting materials (e.g. ketones, β-ketoesters, β-diketones, and aldehydes), as well as the operational simplicity of this process, a convenient, practical, and highly modular pyrazole synthesis has been developed. We believe that this work will arouse more research interest in the organocatalytic synthesis of other biologically active heterocycles. Such studies are currently underway in our laboratory. Dipoles apart: In situ formed enamines react with diazoacetates under mild conditions to afford the corresponding polysubstituted pyrazoles in good-to-excellent yields through an inverse-electron-demand 1,3-dipolar cycloaddition process (see scheme).
