“…The calix [4]pyrroles are obtained by the condensation of pyrrole with acetone in the presence of an acid (Scheme 7a) [75]. Therefore, based on the use of ketone, the reaction with pyrrole, various derivatives of calix [4]pyrroles can be synthesized (Scheme 7b) by slight modifications in the reaction conditions [76].…”

Oxidative stress due to the high levels of reactive oxygen species (ROS) that damage biomolecules (lipids, proteins, DNA) results in acute inflammation. However, without proper intervention, acute inflammation progresses to chronic inflammation and then to several chronic diseases, including cancer, myocardial infarction, cardiovascular diseases, chronic inflammation, atherosclerosis, and more. There has been extensive research on the antioxidants of natural origin. However, there are myriad possibilities for the development of synthetic antioxidants for pharmacological applications. There is an increasing interest in the identification of novel synthetic antioxidants for the modulation of biochemical processes related to ROS. In this regard, derivatives of supramolecules, such as calix[n]arene, resorcinarene, calixtyrosol, calixpyrrole, cucurbit[n]uril, porphyrin etc. are gaining attention for their abilities to scavenge the free radicals. Supramolecular chemistry offers excellent scaffolds for the development of novel antioxidants that can be used to modulate free radical reactions and to improve the disorders related to oxidative stress. This review focuses on the interdisciplinary approach for the design and development of novel synthetic antioxidants based on supramolecular scaffolds, with potentially protective effects against oxidative stress.

“…Our group has reported synthesis of hydrazide derivatives of different calixarene platforms for the preparation of gold, silver and palladium nanoparticles [22][23][24][25][26][27][28][29][30] acids, peptides, proteins, and carbohydrate, like ultimate substrates in biological processes, by synthetic receptors is a topic of great concern from both a host-guest chemistry and analytical application point of view [31][32][33][34][35]. Naturally occurring amino acids have recently been the topic of abundant investigation due to the functional and structural prominence of such interactions in chemistry and biology.…”

“…Numerous receptors can be generated using calix[4]pyrroles due to their huge potential for functionalization. These include neutral, cation and anion recognition, [25] electrochemical sensors, [26] fluorescent sensors, [27] colorimetric sensors, [28] ion selective electrodes, [29] stationary phase‐based division of oligonucleotides, [30] biological active species [31] and act as a catalyst in numerous reactions [32] . Also, Chauhan and co‐workers used GO as a catalyst in the preparation of calix[4]pyrrole and dipyrromethane compounds [33] .…”

Efficacious Removal of Flonicamid Insecticide from Water by GO@functionalized Calix[4]pyrrole: Synergistic Effect in Adsorption

et al. 2023

The presence of a highly toxic pyridine carboxamide insecticide, namely flonicamid in water bodies poses a serious risk to both the aquatic ecosystem and human health. Therefore, a graphene oxide (GO) decorated with azo‐functionalized calix[4]pyrrole i. e. GO‐azocalix[4]pyrrole (GACP) was synthesized to study the removal of flonicamid insecticide through adsorption. The nano‐adsorbent was characterized by IR, XPS, TGA, Raman, SEM, and TEM data. The effect of concentration of flonicamid solution, contact time, adsorbent dosage, temperature, and pH was investigated in the batch adsorption process. Experimental data suggested that equilibrium was attained within 40 min and adsorption efficiency was 93.28 %. The synergistic effect of GO and azocalix[4]pyrrole played an important role in the adsorption. The Langmuir isotherm was followed and the maximum adsorption capacity was found to be 11.43 mg/g. The pseudo‐second‐order kinetic data was well obeyed and thermodynamic investigation suggested the feasible and spontaneous nature of flonicamid onto GACP nanocomposite.
