“…The effectiveness of the approach for long-term protection of high strength aluminum alloys against atmospheric corrosion is discussed [5][6][7][8]. Anticorrosion nano-containers can be incorporated into coating materials as corrosion inhibitor inclusion complexes with cyclodextrin [9][10][11]. The molecular structure of cyclodextrins is shown in Fig.…”

Smart corrosion-inhibiting coatings generate or release an inhibitor only when demanded by the initiation of corrosion. Supramolecular nanocontainers of the α-cyclodextrin (α-CD) corrosion inhibitor were prepared by inclusion complex (IC) formation between α-CD and 2-mercaptobenzothiazole (MBT) or 2-mercaptobenzimidazole (MBI) under various conditions (at room temperature and under sonic energy). The structure of the supramolecular nanocontainers was characterized by hydrogen nuclear magnetic resonance ( 1 H-NMR), x-ray diffraction (XRD), scanning electron microscopy (SEM) and fourier transform infrared spectroscopy (FTIR). Supramolecular nanocontainer formation between MBT and MBI with α-CD in solid phase was emphasized by the significant differences between the 1 H-NMR, FTIR and XRD spectra of the physical mixtures with respect to those of the complexes. The crystalline complexes adopted a head to head channel-type and cage conformation for α-CD/MBT and α-CD/MBI inclusion complexes, respectively.

“…These results indicate that based on the compound's structure, the interaction with BSA from the point of view of the excited state of the dyes can be a tricky subject. The association (K) of compound 12 with BSA was also obtained by the Benesi-Hildebrand equation for 1:1 complex [59]. Figure 7 presents the plot of 1/(I−I 0 ) vs. 1/[BSA].…”

Interaction Study between ESIPT Fluorescent Lipophile-Based Benzazoles and BSA

In this study, the interactions of ESIPT fluorescent lipophile-based benzazoles with bovine serum albumin (BSA) were studied and their binding affinity was evaluated. In phosphate-buffered saline (PBS) solution these compounds produce absorption maxima in the UV region and a main fluorescence emission with a large Stokes shift in the blue–green regions due to a proton transfer process in the excited state. The interactions of the benzazoles with BSA were studied using UV-Vis absorption and steady-state fluorescence spectroscopy. The observed spectral quenching of BSA indicates that these compounds could bind to BSA through a strong binding affinity afforded by a static quenching mechanism (Kq~1012 L·mol−1·s−1). The docking simulations indicate that compounds 13 and 16 bind closely to Trp134 in domain I, adopting similar binding poses and interactions. On the other hand, compounds 12, 14, 15, and 17 were bound between domains I and III and did not directly interact with Trp134.

“…In supramolecular chemistry, host-guest chemistry describes complexes that are composed of two or more molecules or ions that are held together in unique structural relationships by forces other than those of full covalent bonds. In our earlier results are focused the study of complexation of some organic compounds with β-CD based on proton shift effect [30][31][32] . Many inclusion complexes of guests with CDs were studied by these methods [33][34] .…”

3-hydroxy-2-phenylchromen-4-one (HF) is a flavonols that is formed when hypoxanthine is attached to a ribose ring (also known as a ribofuranose) via a β-N9-glycosidic bond. Cyclodextrins are able to form host-guest complexes with hydrophobic molecules given the unique nature imparted by their structure.As a result, these molecules have found a number of applications in a wide range of fields. The inclusion complex of HF with 2HP-β-CD is prepared by various synthetic method such as physical method (PM), kneading method (KM) and co-precipitation method (CP). The solid inclusion complex is characterized by UV, luminescence spectra, Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM) and powder X-ray diffraction (XRD). The anticancer activity of the solid complex is performed against breast cancer cell line and it is noticed that there is no much better activity than the HF alone. Both the HF and its solid complex showed the poor anticancer activity against MDA MB 231 cell line.
