Abstract
Background: Identification of molecules having dual capabilities to reduce postprandial hyperglycemia and oxidative stress is one of the therapeutic approaches to treat diabetes mellitus. In this connection, a library of benzofuran-linked chalcone derivatives were evaluated for their dual action. Methods: A series of substituted benzofuran-linked chalcones (2-33) were synthesized and tested for α-amylase inhibitory as well as 2,2-diphenylpicrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activities. Results: All compounds showed α-amylase inhibitory activity ranging from IC50 = 12.81 ± 0.03 to 87.17 ± 0.15 μM, compared with the standard acarbose (IC50 = 13.98 ± 0.03 μM). Compounds also demonstrated radical scavenging potential against DPPH and ABTS radicals. Conclusion: The identified compounds may serve as potential leads for further advanced research.

Fabrication and Determination of the Sun Protection Factor and Ultraviolet Protection Factor for Piscean Collagen/Bischalcone Derivative (B1) Composite Films with Wide-Range UV Shielding. ACS OMEGA 2022; 7:27876-27885. [PMID: 35990438 PMCID: PMC9386800 DOI: 10.1021/acsomega.2c00772] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/07/2022] [Accepted: 07/20/2022] [Indexed: 06/15/2023]
Abstract
The present study investigates the development of distinct UV-A and UV-B radiation filtering materials through the introduction of a heterocyclic bischalcone derivative [(3,5-bis{[4-(methylsulfanyl)phenyl]methylidene}piperidin-4-one] (B1) into the matrix of PVA/Piscean collagen blend films (1:1) prepared through the solution casting method and characterized. The dopant concentration varied from 0.25 to 4%. The scanning electron microscopy images showed the rough surface due to the uniform dispersion of dopant B1. The addition of different concentrations of B1 altered the mechanical strength with a proportional increase in Young's modulus (146-317 MPa), tensile strength (23.3-39.21 MPa), and decrease in its elongation at break (158.8-105.2%). As the dopant B1 belongs to the bischalcone class of compounds which absorb in the UV-vis region (370 nm λmax) due to the α, β unsaturated keto group, it was selected for doping. Dopant concentration-dependent increase in density was observed in films (31-162 mg/cm3). The bathochromic shift in UV absorption from 370 to 390 nm for λmax as well as hyperchromism was evidenced with proportional increase in the concentration of B1, indicating its capacity to block UV rays. On determining the UV filtering ability for all the prepared films, the one with 4% dopant showed a higher sun protection factor (SPF) with a value of 27.53 and ultraviolet protection factor (UPF) with a value of 58.23. In addition, the degradation of supercoiled PBR322 DNA on UV irradiation was effectively inhibited by these films with a dopant concentration of 0.5-4.0%, which might cause less harm to the skin. The inferences of the experiments would indicate the use of these water-insoluble films as UV blocking potential materials with a merit of SPF and UPF characteristics.

Abstract
A new bischalcone comprising of hexyloxy (-OC6H2n+1) chain based on 'Donor (D)-π-Donor (D)' system was successfully designed and synthesized to demonstrate as emitting material for single-layer OLEDs. Density functional theory (DFT) assessment at B3LYP/6-31G(d,p) was computed to obtain frontier molecular orbitals (FMOs), chemical reactivity and molecular electrostatic potential (MEP). The utilization of alkoxy substructure towards the chalcone moiety has increased the solubility and contributed to HOMO-LUMO gap energy level 3.473 eV by UV-Vis spectroscopy and was found to have good agreement with the theoretical calculations. The investigations on their optical, electrochemical and thermal behaviour also were conducted via UV-Vis, cyclic voltammetry (CV), thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The entitled alkoxylated bischalcone (CSAB) revealed good thermal stability up to 300 °C and showed high glass transition temperatures. At positive potential, a quasi-reversible oxidation (Eox 1/2) peak at 2.40 V and negative potentials exhibited reduction peak at 0.78 V, respectively. The application of CSAB was tested in the form of thin film in respect to its conductivity in terms of electrical current and electroluminescence behaviour. It gave an intense yellow emission which has provided depth fundamental understanding on its potentiality featuring alkoxylated bischalcone moiety as solution-processed OLED material in optoelectronic interests.

Abstract
A very simple chemodosimeter has been developed for creatinine biomolecules based on Michael addition reaction by using ( E)-3-(Pyren-2-yl)-1-(3,4,5-trimethoxyphenyl)prop-2- en-1-one Chalcone. The photophysical properties of the chalcone were thoroughly analyzed using UV-vis and emission techniques. The chalcone has exhibited two absorption maxima at 297 and 407 nm which are due n-π* and π-π* transactions, respectively. This property was further confirmed by repeating UV-vis absorbance studies of the chalcones in different solvents having different polarity. The PTP chalcone has originally exhibited ICT mechanism and it is arrested while creatinine is added. However, a ratiometric response is observed due to the creatinine induced ICT mechanism and it is also clearly supported with DFT studies. In our original work, we did DFT studies for only one isomer of the creatinine. Currently, we have extended our DFT studies for another isomer also. The relative quantum yield of the PTP chalcone was calculated in sensing and standard conditions as 0.85 and 0.45, respectively.

Abstract
The asymmetric unit of the title compound, C24H14F4O2, comprises of one and a half mol-ecules; the half-mol-ecule is completed by crystallographic inversion symmetry. In the crystal, mol-ecules are linked into a three-dimensional network by C-H⋯F and C-H⋯O hydrogen bonds. Some of the C-H⋯F links are unusually short (< 2.20 Å). Hirshfeld surface analyses (dnorm surfaces and two-dimensional fingerprint plots) for the title compound are presented and discussed.
