Abstract
This study aimed to design and fabricate novel hydroxypropyl-β-cyclodextrin-based hypercrosslinked polymers, called nanosponges, as carriers for anticancer hydrophobic agents and compare them with host–guest complexes of hydroxypropyl-β-cyclodextrin, a remarkable solubilizer, to investigate their application in improving the pharmaceutical properties of the flavonoid naringenin, a model hydrophobic nutraceutical with versatile anticancer effects. For this purpose, three new nanosponges, crosslinked with pyromellitic dianhydride, citric acid, and carbonyldiimidazole, were fabricated. The carbonate nanosponge synthesized by carbonyldiimidazole presented the highest naringenin loading capacity (≈19.42%) and exerted significantly higher antiproliferative effects against MCF-7 cancer cells compared to free naringenin. Additionally, this carbonate nanosponge formed a stable nanosuspension, providing several advantages over the naringenin/hydroxypropyl-β-cyclodextrin host–guest complex, including an increase of about 3.62-fold in the loading capacity percentage, sustained released pattern (versus the burst pattern of host–guest complex), and up to an 8.3-fold increase in antiproliferative effects against MCF-7 cancer cells. Both naringenin-loaded carriers were less toxic to L929 murine fibroblast normal cells than MCF-7 cancer cells. These findings suggest that hydroxypropyl-β-cyclodextrin-based carbonate nanosponges could be a good candidate as a drug delivery system with potential applications in cancer treatment.

Abstract
Dovitinib has been investigated as an anti-tumor drug due to its ability to inhibit multiple receptor tyrosine kinases. Dovitinib free base has a poor water solubility leading to poor absorption. Salts and lipid-based formulations have been used to improve drug availability. Here, we investigated the physiochemical properties of the dovitinib free base in the presence of some pharmaceutical excipients. We sought to study the effect of acidic counterions on the aqueous solubility and lipophilicity of dovitinib and how pH, buffer species, and cyclodextrin (CD) influenced dovitinib stability. pH-solubility studies were performed by titration against five different acids. Aqueous solubility of dovitinib salt depended on the counterion. Lactic acid greatly increased the aqueous solubility of dovitinib. The counterion effect on the solubility was also investigated in the aqueous complexing media. Unexpected synergistic solubilization was found with γ-CD/phosphoric acid and γ-CD/maleic acid. The counterion did not affect the lipophilicity of dovitinib at physiological pH. Accelerated degradation of dovitinib was carried out at high temperature. Stability was studied across a range of pH values, buffer species and in the presence of two CDs. Dovitinib was most stable at pH 4 in the phosphate buffer species. γ-CD stabilized the drug at relatively low pH.

Saudi Pharm J 2021; 29:223-235.

Abstract
The long-term objective of the present study was to prepare, physicochemically characterize and determine the anticancer of clausenidin/hydroxypropyl-β-cyclodextrin (Clu/HPβCD) inclusion complex. We used differential scanning calorimetry, X-ray diffractometer, fourier transform infrared spectroscopy, ultraviolet–visible spectrophotometer and 13C and 1H nuclear magnetic resonance followed by in vitro anticancer assays. The orientation and intermolecular interactions of Clausenidin within cyclodextrin cavity were also ascertained by molecular docking simulation accomplished by AutoDock Vina. The guest molecule was welcomed by the hydrophobic cavity of the host molecule and sustained by hydrogen bond between host/guest molecules. The constant drug release with time, and increased solubility were found after successful complexation with HPβCD as confirmed by physicochemical characterizations. Clausenidin had greater cytotoxic effect on colon cancer HT29 cells when incorporated into HPβCD cavity than dissolved in DMSO. Also, from a comparison of cell viability between normal and cancer cells, a reduced side effect was observed. The Clu/HPβCD inclusion complex triggered reactive oxygen species-mediated cytotoxicity in HT29 cells. The inclusion complex-treated HT29 cells showed cell cycle arrest and death by apoptosis associated with caspases activation. The presence of HPβCD seems to aid the anticancer activity of clausenidin.
