Potential of C-Phenylcalix[4]Resorcinarene Epoxide Compound as Drug Delivery Agent in Breast Cancer Cells MCF-7

Multifaceted Characterization and Therapeutic Evaluation of Co-precipitated Cobalt Ferrite Nanoparticles for Magnetic Hyperthermia Cancer Therapy

Aim

Magnetic-mediated hyperthermia has emerged as a promising therapeutic approach for treating cancer. This technique employs the heat dissipated by the magnetic nanoparticles when subjected to an external varying magnetic field, to bring about localized hyperthermia in tumor tissues. Owing to their conducive and tuneable "physical, chemical, and magnetic" characteristics, cobalt ferrite (CoFe2O4) nanoparticles are recognized as emerging contenders. The aim of the present work was to enhance the magnetic characteristics and guarantee the efficacy of CoFe2 O4 nanoparticles in targeting and eliminating cancer cells.

Methods

CoFe2O4 nanoparticles were synthesized using the chemical co-precipitation route and underwent rigorous structural, morphological, and magnetic characterization techniques. The synthesized particles were then subjected to in vitro studies to evaluate their cytotoxicity and antimicrobial susceptibility.

Results

The characterization techniques confirmed the cubic structure, ferrite phase, and spherical and magnetic nature of CoFe2O4 nanoparticles. The zeta potential was found to be - 0.0048V (4.8 mV). Cytotoxicity analysis exhibited decreased cell viability with increasing concentrations of CoFe2O4 nanoparticles. Antimicrobial studies displayed good inhibiting properties.

Conclusion

The zeta potential of the synthesized CoFe2O4 nanoparticles was found to be higher than that of the breast cancer cells (MCF-7) which proves the synthesized drug to be effective. The in vitro studies also disclose the efficacy of the drug over cancer cells.

Oliveramine: An Isolated Alkaloid from Fagraea fragrans (Tembesu) Bark

This paper described the progress of phytochemical, especially alkaloids, work on Fagraea fragrans species (tembesu), Loganiaceae. A dimeric-pyridine alkaloid with molecular formula C20H20O4N2 has been successfully isolated from diethyl ether extracts from this plant’s barks. The alkaloid was explored from diethyl ether extracts using sulphuric acid (2%), then basified with ammonium hydroxide (25%) until the solution had a pH of 10.5. The later solution was extracted again with chloroform. The alkaloid residue was subjected to column chromatography and eluted with 10% acetone in chloroform. The chemical structure of the isolated dimeric-pyridine alkaloid was determined by LCMS/MS, 13C-NMR, and 1H-NMR spectroscopies. As a result, the isolated dimeric-pyridine alkaloid was closely similar to the oliveramine alkaloid, and this is also the first report about oliveramine from Fagraea fragrans (F. Fragrans).
