Synthesis and molecular docking study of ethyl piperidine-1-carboxylate derivative Schiff bases

Org. Commun. (2025) 18:1 ; 28 - 37
by Sertan Aytaç

In the present study, new Schiff bases (14-16) were obtained from the condensation reaction of Ethyl 4-aminopiperidine-1-carboxylate and 2/3/4-pyridine carboxyaldehyde compounds. Desired compounds were successfully synthesized with high yields in a short time.  Chemical characterization (1H-NMR, 13C-NMR and elemental analysis) and molecular docking studies of the synthesized compounds were performed against the 7XN1 structure (human acetylcholinesterase in complex with tacrine) and reference drug (Donepezil and Tacrine). It was determined that compound 16 (-7.52) had higher binding energy than Tacrine (-7.48), and compounds 14 (-7.34) and 15 (-7.41) showed values ​​close to Tacrine (-7.48). The synthesized compounds can be potent inhibitors for hAChE.

Baker’s yeast as a biocatalyst for efficient and substrate-selective N-acetylation of anilines

Org. Commun. (2025) 18:1 ; 17 - 27
by Qasim Ullah , Samreen Kausar , Abida Murtaza and Aarifa Maryam

In the present study, we have developed an efficient N-acetylation method of anilines under green and eco-friendly conditions, where Baker’s Yeast (BY) was used as biocatalyst. The results of this study clearly demonstrate towards the N-acetylation of only anilines to form acetanilides (3a-i) with acetic anhydride in good to excellent yield. Interestingly, acetylation of phenol/thiophenol, aliphatic amines/heterocyclic amines and amino acids failed under the same conditions. This N-acetylation reaction with substrate-selective follows simple procedure and requires simple work up. Thus, we can conclude that the present method is a simple, efficient, substrate selective and eco-friendly.

Organic heterocyclic compounds as ionophores: recent progress in potentiometric sensing

Org. Commun. (2025) 18:1 ; 3 - 16
by Nataliya Korol , Dzhosiya Molnar-babilya and Mikhailo Slivka

This review article provides a comprehensive analysis of the advancements in organic heterocyclic compounds as ionophores for potentiometric sensors over the past decade. It highlights their critical role in modern analytical chemistry and their impact on sensor performance. Various classes of heterocyclic ionophores—including five-membered monoheterocyclic compounds (e.g., pyrazole and 1,2,4-triazole derivatives), pyridine derivatives, condensed heterocyclic compounds (such as indoles, quinazolines, cucurbiturils, benzimidazoles, benzothiazoles, carbazoles, and thiazines), Schiff bases, and macroheterocyclic compounds—are systematically reviewed. Special emphasis is placed on the design, synthesis, and optimization of these ionophores within polymer-based and PVC membrane electrodes, along with their key performance parameters such as linear concentration ranges, detection limits, response times, and ion selectivity. By analyzing research findings from the last 10 years, this review underscores the advantages of organic heterocyclic ionophores in terms of selectivity, stability, and versatility, making them highly suitable for applications in environmental monitoring, clinical diagnostics, food safety, and industrial analysis. Additionally, emerging trends and ongoing challenges in potentiometric sensor development are discussed, offering insights into future research directions in this rapidly evolving field.
