Synthesis and Characterization of Inulin-Based Responsive Polyurethanes for Breast Cancer Applications

In this study, new polyurethanes (PUs) were prepared by using inulin and polycaprolactone as polyols. Their structure and morphology were determined by Fourier transform infrared spectroscopy (FTIR), Raman dispersive spectroscopy, Nuclear magnetic resonance spectroscopy ( 1 H NMR and 13 C NMR), and scanning electron microscopy (SEM), whereas their mechanical properties were evaluated by a universal testing machine. Additionally, their water uptake, swelling behavior, and degradation were evaluated to be used as drug delivery carriers. Therefore, an anti-cancer drug was loaded to these PUs with 25% of loading efficiency and its release behavior was studied using different theoretical models to unveil its mechanism. Finally, the ability of the new PUs to be used as a clip marker in breast biopsy was evaluated. The results clearly demonstrate that these PUs are safe and can be used as intelligent drug release matrices for targeted drug delivery and exhibits positive results to be used for clip marker and in general for breast cancer applications.

“…Additionally, of course, the pH was changed with the species of lactobacilli (Table 2). The reductions of pH in the PGF or P95s groups were probably due to the metabolites, like lactic acid and acetic acid, produced by lactobacilli, or the SCFAs, the fermentation products from inulin [11,38]. All these results indicated that the PGF was a potential prebiotic, stimulating the growth of lactobacilli and with a lower pH.…”

Characterization of Inulin-Type Fructan from Platycodon grandiflorus and Study on Its Prebiotic and Immunomodulating Activity

Platycodon grandiflorus is a plant widely used in traditional Chinese medicine, of which polysaccharides are reported to be the main components responsible for its bio-functions. In this work, the inulin-type fructan (PGF) was obtained by DEAE anion exchange chromatography from the water extracted from P. grandifloras. Characterization was performed with methanolysis, methylation, and NMR and the results showed that PGF is a β-(2-1) linked fructan, with terminal glucose and with a degree of polymerization of 2–10. In order to study its biofunctions, the prebiotic and immunomodulation properties were assayed. We found that PGF exhibited good prebiotic activity, as shown by a promotion on six strains of lactobacillus proliferation. Additionally, the PGF also displayed direct immunomodulation on intestinal epithelial cells and stimulated the expressions of anti-inflammatory factors. These results indicated that the inulin from P. grandiflorus is a potential natural source of prebiotics as well as a potential intestinal immunomodulator, which will be valuable for further studies and new applications.

“…Combining 13 C and HMQC NMR spectra, it could be inferred that the signal at δ 92.17 ppm was attributed to C-1 of α-Glcp and signal at δ103.72 ppm was attributed to C-2 of β-Fruf, respectively (Sheila et al, 2017). On account of fructose being 2-ketose, there was no corresponding H-2 signals in the 1 H NMR spectra.…”

Firmness and soluble solids content in Annona squamosa during storage were studied. Changes in total Annona squamosa polysaccharides (TASP) obtained by alcohol precipitation and corresponding ethanol supernatants (TASP‐S) during storage were analyzed. Ethanol supernatants from Annona squamosa stored for 3 days (TASP‐S3) were chosen and small molecule carbohydrate (TASP‐S3‐1) in it was characterized in structure. Activities of related enzyme during storage were determined. Results indicated firmness exhibited a significant decline from 1 day to 3 days and soluble solids content fluctuated during storage. With prolonged storage time, relative content of each component in TASP varied and that of carbohydrate with higher molecular weight gradually decreased. So was the compositions in TASP‐S during storage. TASP‐S3‐1 was ultimately identified to be saccharose. Enzyme assays indicated activities of related enzymes varied during storage, and acid invertase, sucrose synthase might play more important roles in improving the quality and nutrition of postharvest Annona squamosa. Practical applications This work lay the foundation for further studying carbohydrate metabolism and controlling the quality of postharvest Annona squamosa. Because the relative contents of each components in TASP and TASP‐S, changed with the extension of storage time. Besides, among these related enzymes, acid invertase and sucrose synthase would be more important in postharvest Annona squamosa, which provided critical information on improving the quality and nutrition of Annona squamosa in further study.
