AI Article Synopsis

  • The study focuses on synthesizing and evaluating 15 new compounds derived from curcuminoids as potential treatments for trypanosomiasis.
  • These compounds were created through a cyclization reaction with hydrazines and tested for their effectiveness against trypanosome parasites.
  • Two specific derivatives showed significant activity against the parasites while remaining non-toxic to healthy cells, indicating a potential for further development as effective inhibitors.

Article Abstract

We report the synthesis and biological evaluation of a small library of 15 functionalized 3-styryl-2-pyrazolines and pyrazoles, derived from curcuminoids, as trypanosomicidal agents. The compounds were prepared via a cyclization reaction between the corresponding curcuminoids and the appropriate hydrazines. All of the derivatives synthesized were investigated for their trypanosomicidal activities. Compounds and showed significant activity against epimastigotes of , with IC values of 5.0 and 4.2 μM, respectively, accompanied by no toxicity to noncancerous mammalian cells. Compound was found to effectively inhibit triosephosphate isomerase. The up to 16-fold higher potency of these derivatives compared with their curcuminoid precursors makes them a promising new family of inhibitors.

Background: A heterocyclic molecule containing five rings, three carbon atoms, two nitrogen atoms, and a single endocyclic bond is called pyrazoline. Because of its intriguing electrical characteristics and potential for dynamic applications, pyrazoline is one type of electron-rich nitrogen carrier that is becoming more and more popular. This study synthesizes pyrazoline derivatives using a variety of techniques to demonstrate a highly biological function.

Easily obtainable and efficient chiral -symmetric bipyridine-,'-dioxide ligands with Ni(OTf) were developed for application in catalyzing [3 + 2] cycloaddition reactions to synthesize optically active fused pyrazolidines or pyrazoline derivatives featuring three contiguous stereogenic centers by employing azomethine imines and α,β-unsaturated 2-acyl imidazoles, affording the corresponding adducts with the opposite configuration compared to previous synthetic products in 80-98% yields with 28-99% ee and >20:1 dr. In addition, subsequent amplification experiments and derivative transformations of the product further demonstrated the efficient catalytic performance of the catalyst Ni(II)-bipyridine-,'-dioxide complexes and the practicality of this synthesis methodology.

A simple pyrazoline derivative BBD has been synthesized for detecting Cu in EtOH/HEPES (v/v = 1 : 1, pH = 7). The probe has high selectivity for Cu by quenching the fluorescence intensity and was sensitive to pH. When excited at 398 nm, fluorescence is emitted at 520 nm with a Stokes shift of 122 nm, which is larger than that of other reported pyrazoline skeleton probes.

HER2 overexpression significantly contributes to the aggressive nature and recurrent patterns observed in various solid tumors, notably gastric cancers. Trastuzumab, HER2-targeting monoclonal antibody drug, has shown considerable clinical success; however, readily emerging drug resistance emphasizes the pressing need for improved interventions in HER2-overexpressing cancers. To address this, we proposed targeting the protein-protein interaction (PPI) between ELF3 and MED23 as an alternative therapeutic approach to trastuzumab.
