Introduction and aim. At present, several microbial diseases are prominent and of concern worldwide. The intent of this study was to examine the antibacterial potential of newly synthesized tetradentate macrocyclic complexes against different bacte rial strains. The macrocyclic scaffold has gained attention as a biologically active class of supramolecular chemistry due to its unique properties and ability to target various microorganisms. Thus, the goal of the present study was to develop a series of biologically active transition metal-based macrocycles. Material and methods. All macrocyclic compounds were synthesized by a template method and validated by molar conductiv ity, elemental studies, and spectral and magnetic studies. Antibacterial activities of all metal complexes were evaluated against Escherichia coli (MTCC 739) and Staphylococcus aureus (MTCC 731) bacterial strains by taking ampicillin as a standard reference drug. DNA photocleavage potential was explored using agarose gel electrophoresis. Results. Results revealed the formation of novel macrocyclic complexes via tetra nitrogen bond trapping of metals. Copper complexes have strong potential against S. aureus bacteria as copper and nickel both show good DNA photocleavage potential. Conclusion. The findings endorse the biomedical relevance of these macrocyclic scaffolds, suggesting avenues for further exploration in targeted drug delivery and potential clinical applications. The proposed octahedral geometry for the complexes enhances our understanding of their structural aspects. This research contributes substantively to the field, laying the foundation for future investigations in advanced antimicrobial design and application.

Introduction and aim. The novel advancements of upcoming iron regulators used to treat diabetic nephropathy have implicated a common manifestation of combination chelation therapy used to eliminate end-stage renal disease associated with inflammation and iron imbalance that is altered by renal iron absorption. However, iron accumulation in the clustered kidneys that filter blood may cause problems that affect diabetic blood sugar regulation. Material and methods. A well-designed method was employed to discover relevant research publications on iron chelators and their potential to treat diabetic nephropathy. “Iron chelators”, “diabetic nephropathy”, “end-stage renal disease”, and “chelation therapy” were searched in Google Scholar, Web of Science, PubMed, and EMBASE. Analysis of literature. Although the specific etiology and development have not been fully explored, emerging evidence on iron pathophysiology helps comprehend the pathogenesis of acute kidney damage and chronic kidney disease, which crucially provides novel iron chelation therapy techniques. Ferroptosis and hepcidin marker proteins increase oxidative/nitrifying stress and kidney injury. Iron chelator medicines including deferoxamine, deferasirox, and deferiprone were tested as prophylactic strategies. Conclusion. This article covers both preclinical and clinical aspects of iron chelators to avoid diabetic nephropathy, including novel iron therapies that must be reviewed when selecting dosing regimens.
Exploring the versatility of ciclopirox – from anti-fungal to anticancer agent and beyond
(Publishing Office of the University of Rzeszow, 2023-12) Singh, Dhishank; Kaur, Ginpreet; Chintamaneni, Meena; Joshi, Hemant; Ramniwas, Seema; Tuli, Hardeep Singh
Introduction and aim. Ciclopirox has been treating fungal infections for decades. Recent studies suggest ciclopirox may be repurposed to treat cancer, viral infections, and neurological disorders. Ciclopirox exerts anticancer by inhibiting multiple pathways of cancer cell growth and survival and anti-viral actions by reducing viral replication and altering the host immunological response to viral infection. Recent research suggests that ciclopirox may protect against neurodegenerative illnesses including Alzheimer’s and Parkinson’s. This narrative review shows ciclopirox’s potential to treat cancer, viral infections, and neurological diseases. Material and methods. Current relevant research publications focused on ciclopirox and its repurposing medicinal potential, therefore a well-designed technique was used to find them. „Ciclopirox”, „Anti-fungal”, „Anti-cancer”, „Repurposing”, and „Therapeutic potential” were used to search PubMed, Web of Science, EMBASE, and Google Scholar. Analysis of literature. Ciclopirox may reduce oxidative stress and inflammation, which may cause several illnesses. Overall, the repurposing of ciclopirox for the treatment of cancer, viral infections, and neurodegenerative disorders represents a promising avenue of research that warrants further investigation. Conclusion. It was concluded that CPX and olamine derivatives as outstanding antifungal medications, as well as provide information on ongoing research to use them for other illnesses.

Introduction and aim. The synthesis of heterocyclic compounds containing oxygen and nitrogen is profoundly intriguing due to their mechanistic implications in both research and development within organic chemistry and drug discovery. The primary aim of this study is to fabricate a range of pharmacologically active drugs containing the isoxazole moiety. Material and methods. The synthesis of new derivatives of isoxazole was achieved through a one-pot condensation reaction of 2-[(Substituted phenyl)hydrazono]malononitrile (1) and 3-[(Substituted phenyl)azo]-2,4-Pentanedione (2) with sodium acetate and hydroxylamine hydrochloride (1:1) in ethanol. All the compounds were screened for their in vitro antibacterial activity, in vitro antioxidant and anticancer activity. The synthesized compounds underwent characterization through FTIR, 1 H NMR, and 13C NMR analyses, supported by mass spectral data and elemental analysis. Results. A set of novel isoxazole derivatives was synthesized with a favorable yield. Among compounds 1d, 1e, 2c, 2d, and 2e exhibited notable antioxidant activities. Compounds 1a, 1b, and 1c demonstrated significant anticancer potential against prostate cancer [PC3] cell lines compared to normal HEK cell lines, while 2a displayed the highest inhibitory zone against Escherichia coli. Conclusion. Novel compounds with multifaceted biological activities have been successfully designed, and a synthetic route to create isoxazole derivatives has been devised and verified.
