Herein, in order to improve the bioavailability of a non-biodegradable pollutant, inclusion complexation procedures had been used to develop better formulations of this pollutant, Bisphenol A (BPA). In our research, an inclusion complex (IC) of β-cyclodextrin (β-CD) with BPA was formed to investigate the effect of β-CD on the water solubility, anti-oxidant, anti-bacterial activity, toxicity, and thermal stability of BPA. UV-Vis and other spectrometric methods such as NMR, FTIR, and XRD indicated the molecular mechanism of interactions between β-CD and BPA, which was further hypothesized using molecular modeling to confirm preliminary results. Studies of TGA and DSC demonstrated that encapsulation boosted the thermal stability of BPA. This research also makes predictions about BPA's release behavior when CT-DNA is present. In vitro testing of the IC's antibacterial activities showed that it outperformed pure BPA. The in silico study was found to have a considerable decrease in toxicity level for IC compared to pure BPA. Therefore, β-CD-encapsulated BPA can lessen toxicity by raising antioxidant levels. Additionally, as its antibacterial activity increases, it may be employed therapeutically. Thus, this discovery of creating BPA formulations with controlled release and/or protective properties allows for a more logical application of BPA by reducing its hazardous effects through boosting its efficacy.
在此,为了提高不可生物降解污染物的生物利用度,采用包合作用程序来开发这种污染物双酚 A(BPA)的更好配方。在我们的研究中,形成了β-环糊精(β-CD)与 BPA 的包合物(IC),以研究β-CD 对 BPA 的水溶性、抗氧化、抗菌活性、毒性和热稳定性的影响。紫外-可见和其他光谱方法,如 NMR、FTIR 和 XRD,表明了β-CD 和 BPA 之间相互作用的分子机制,进一步使用分子建模假设来确认初步结果。TGA 和 DSC 的研究表明,包封提高了 BPA 的热稳定性。这项研究还预测了当存在 CT-DNA 时 BPA 的释放行为。IC 的体外抗菌活性测试表明,它优于纯 BPA。与纯 BPA 相比,IC 的计算机研究被发现毒性水平有相当大的降低。因此,β-CD 包封的 BPA 可以通过提高抗氧化水平来降低毒性。此外,随着其抗菌活性的提高,它可能在治疗上得到应用。因此,通过提高功效来减少其有害影响,这种具有控制释放和/或保护特性的 BPA 制剂的发现允许更合理地应用 BPA。
