“…The stretching of band vibration of CO, C–N, and N–H is represented for amide II at 1545 cm –1 while amide I shows its peak at 1658 cm –1 . For β-cyclodextrin, it is at 3376, 2933, 1650, 1208, and 1030 cm –1 attributed to O–H, C–H stretching, C–C, C–O, and C–O–C stretching vibration, respectively, as reported previously .

Cordycepin gets rapidly metabolized in the body into inactive form due to its structural similarity to adenosine, thus inhibiting its development as a medicinal agent. This study was aimed to improve the solubility and stability of cordycepin, a potential drug with known antiproliferative activity, by encapsulating it in bovine serum albumin: β-cyclodextrin nanoparticles. Cordycepin-loaded nanoparticles (CLNPs) were synthesized using the antisolvent method and characterized thoroughly using various techniques. Our dynamic light scattering measurement showed a particle size and zeta potential of 160 ± 2.75 nm and −20.21 ± 2.1 mV, respectively, for CLNPs. Transmission electron microscopy studies revealed that particles were spherical in morphology. These CLNPs showed sustained release of cordycepin with encapsulation and loading efficiency of 81.62 ± 1.5 and 27.02 ± 2.0%, respectively, based on high-performance liquid chromatography and UV−vis studies. Based on differential scanning calorimetry and zeta potential studies, CLNPs improve cordycepin stability and solubility. Our molecular simulations and binding energy calculation also showed favorable protein interaction between cordycepin, bovine serum albumin, and β-cyclodextrin, further supporting the notion of improved stability. In vitro cytotoxicity, apoptosis, and cellular uptake studies on breast cancer cells showed that the synthesized nanoparticles had greater cytotoxicity as compared to free cordycepin.

“…Other bands for βCD and tosylated βCD are similar: a band at 3100–3600 cm −1 could be attributed to O−H group stretching, and an intense band at 2854 cm −1 to C−H asymmetric/symmetric stretching. The absorption peaks of βCD at 1650, 1160, and 1030 cm −1 are attributed C−C, C−O, and C−O−C stretching vibration of βCD, respectively [47] . The FTIR spectrum for GQD is depicted in Figure 2.…”

Over‐expression of miR21 plays an important role in several cancers by promoting cancer cell proliferation, migration, invasion, and metastasis. Here, we attempted to prepare a beta cyclodextrin‐polyethyleneimine‐graphene quantum dot (βCD‐PEI‐GQD) nanocarrier for cellular delivery of miR21a. For this purpose, tosylated‐βCD and GQD were conjugated to branched PEI. The product was characterized by FTIR, 1H‐NMR, and fluorescence spectroscopy. The morphology, particle size distribution, and ζ‐potential of miR21a were examined by TEM and DLS following overnight incubation with βCD‐PEI‐GQD in aqueous media. The miR21 silencing was measured by stem‐loop RT‐PCR in HepG2 human hepatoma cell line. Cellular uptake and cell toxicity assays were determined by fluorescence microscopy and Trypan blue staining method, respectively. The formation of miR21a/CD‐PEI‐GQD Nanoplex with a decreased average size of 114 nm and a ζ‐potential (+36.1 mV) lower than CD‐PEI‐GQD nanocarrier by adding miR21a was confirmed at optimum C/P ratio =8.7. RT‐PCR revealed that miR21a/βCD‐PEI‐GQD Nanoplex significantly downregulated miR21 expression levels effectively. Overall, miR21a delivery using CD‐PEI‐GQD is presented as a novel trackable nanocarrier for cancer therapy.
