“…Additionally, several research papers reported that supported Schiff base metal complexes were applied in heterogeneous catalysis. Different types of supports were used for the stabilization of Schiff base metal complexes including MOF 22 , silica 23 , Fe 3 O 4 nanoparticles 24 , graphene oxide 25 , carbon nanotube 26 , HY zeolite 27 , and SBA-15 mesoporous silica 28 . Among the support materials, SBA-15 mesoporous silica is one of the valuable and useful supports for the transition metal–ligand complexes with outstanding advantages of high surface area, large pore diameters (with an overall sizing range of 3–30 nm with narrow size distributions), high stable structure, biocompatibility, easy functionalization, and convenient catalyst recycling.…”

Biginelli-type heterocyclic compounds are particularly important due to their several chemical reactivities and various range of pharmacological activity. Therefore Biginelli reaction has witnessed several modification and numerous investigations are continuing in this field to develop more effective and efficient methodologies. In this research, Iron (III) schiff base immobilized SBA-15 has been prepared as a valuable, efficient, and recoverable catalyst for the Biginelli reaction. The morphology of the prepared catalyst was identified by spectroscopic characterization techniques and structural microscopic analysis including Fourier transform infrared (FT-IR) patterns, X-ray diffraction (XRD) by powder crystal method, Energy-dispersive X-ray spectroscopy (EDS) study, Thermogravimetric-Differential thermal analysis (TGA-DTA), Transmission electron microscopy (TEM) and Field emission scanning electron microscopy (FE-SEM) images. Biginelli compounds containing 3,4-dihydropyrimidines and octahydroquinazolinones were conveniently synthesized by this catalyzed protocol from the cycloaddition of aromatic aldehydes with the 1,3-dicarbonyl substrates and urea via ultrasonic waves. The several advantages of the presented approach are high yields and easy isolation of products, shorter reaction times, and milder conditions, structural stability and reusable catalyst. The combination of heterogeneous catalyst and ultrasonic radiation can make catalytic reactions more efficient than traditional ways attractive for academic researchers and application scholars in the industry.

Four lanthanide complexes with 8‐hydroxyquinoline‐2‐aldehyde‐2‐hydrazinopyridine (H‐L1), 8‐hydroxyquinoline‐2‐aldehyde‐2‐hydrazimidazole (H‐L2): [Sm(L1)2][Sm(L1)(NO3)3]·CHCl3·2CH3OH (1), [Gd(L1)2][Gd(L1)(NO3)3]·CHCl3·2CH3OH (2), [Sm(L2)(NO3)2]2·CH3OH (3), and [Eu(L2)(NO3)2]2·CH3OH (4) were synthesized and characterized. In vitro cytotoxicity evaluation showed that the ligands and four lanthanide complexes exhibited cytotoxicity to the five tested tumor cell lines. Among them, complex 1 showed the best antiproliferative activity against NCI‐H460 tumor cells. Mechanistic studies demonstrated that complex 1 arrested the cell cycle of NCI‐H460 cells in G1 phase and induced mitochondria‐mediated apoptosis, which resulted in the loss of mitochondrial membrane potential, enhanced intracellular Ca2+ levels and reactive oxygen species generation. In addition, complex 1 affected the expression levels of intracellular apoptosis‐related proteins and activated the caspase‐3/9 in NCI‐H460 cells. Therefore, complex 1 is a potential anticancer agent.
