In this study, we prepared a β-cyclodextrin polymer (β-CDP) co-loaded quercetin (QCT) and doxorubicin (DOX) nanocarrier (β-CDP/QD NCs) by freeze-dried method to combat P-glycoprotein (P-gp) mediated multidrug resistance (MDR) in KB-Ch 8-5 cancer cells. Various microscopic and spectroscopic techniques were employed to characterize the prepared nanocarrier. The molecular docking studies confirm the effective binding interactions of QCT and DOX with the synthesized β-CD polymer.

DNA forms non-canonical Guanine-rich-quadruplex structures that play crucial roles such as maintenance of the telomere, transcription, and replication. Selective binding of small molecular ligands to G-quadruplexes and stabilization of them gain importance in the control of cell proliferation and development of therapeutics. In this paper, we report the synthesis of a tryptophan-β-cyclodextrin complex and its platinum complex.
