Abstract
In recent years, scientists have been very interested in single crystals of monoaromatic compounds with mechanical softness, but they are hard to find. The present work reports a comparative study of structural, spectroscopic, and quantum chemical investigations of three structurally similar mechanically bending monoaromatic compounds, namely, 2-amino-3-nitro-5-chloro pyridine (I), 2-amino-3-nitro-5-bromo pyridine (II), and 2-amino-3-nitro-5-iodo pyridine (III). The mechanical responses of the three organic crystals studied here are very intriguing due to the similarity of their chemical structures, which only differ in the presence of halogen atoms (Cl, Br, and I) at the fifth position of the pyridine ring and are explained through examining intermolecular interaction energies from energy frameworks analysis, slip layer topology, and Hirshfeld surface analysis. The crystals of all the three feature one dimensional ribbons comprising alternating NaminoH⋯Onitro and NaminoH⋯Npyridine hydrogen bonds that form R22(12) and R22(8) dimeric rings, respectively. In (III), weak I⋯I interactions link the adjacent ribbons forming a two dimensional sheet. Layer-like structures are observed in all three crystals, with no significant interactions between the adjacent architectures (ribbons or sheets). Energy framework calculations are used for estimating the bending ability of the three compounds, with the three following the order Cl ≪ Br < I. The iterative electrostatic scheme coupled with the supermolecule approach (SM) at the DFT/CAM-B3LYP/aug-cc-pVTZ level is used to calculate the third-order nonlinear susceptibility (χ3) values in a simulated crystalline environment for the static case as well as two typical electric field frequency values, (λ = 1064 nm) and (λ = 532 nm). In addition, estimates of the topological studies (localized orbital locator and electron localization function) and reactivity characteristics (global reactivity parameters, molecular electrostatic potential, and Fukui function) are made for the compounds under investigation. Docking studies done using AutoDock software with a protein target (PDB ID: 6CM4) revealed that three compounds could be used to treat Alzheimer's disease.

Remarkable Nonlinear Properties of a Novel Quinolidone Derivative: Joint Synthesis and Molecular Modeling. Molecules 2022; 27:molecules27082379. [PMID: 35458577 PMCID: PMC9028933 DOI: 10.3390/molecules27082379] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2022] [Revised: 03/31/2022] [Accepted: 04/02/2022] [Indexed: 11/16/2022] Open
Abstract
A novel 4(1H) quinolinone derivative (QBCP) was synthesized and characterized with single crystal X-ray diffraction. Hirshfeld surfaces (HS) analyses were employed as a complementary tool to evaluate the crystal intermolecular interactions. The molecular global reactivity parameters of QBCP were studied using HOMO and LUMO energies. In addition, the molecular electrostatic potential (MEP) and the UV-Vis absorption and emission spectra were obtained and analyzed. The supermolecule (SM) approach was employed to build a bulk with 474,552 atoms to simulate the crystalline environment polarization effect on the asymmetric unit of the compound. The nonlinear optical properties were investigated using the density functional method (DFT/CAM-B3LYP) with the Pople's 6-311++G(d,p) basis set. The quantum DFT results of the linear polarizability, the average second-order hyperpolarizability and the third-order nonlinear susceptibility values were computed and analyzed. The results showed that the organic compound (QBCP) has great potential for application as a third-order nonlinear optical material.

Abstract
Cutaneous leishmaniasis is a worldwide public health problem. Conventional therapies, in addition to the high cost, have many adverse effects and cases of parasite's resistance. Chalcones are secondary metabolites precursors in the flavonoid pathway and can be obtained naturally, but with low yield from plant raw material. Thus, the use of synthetic chalcones has been a promising strategy for the development of molecules with leishmanicidal activity. Thus, this work aimed to develop a controlled release system of two synthetic chalcone (trans-chalcones and 3'-(trifluormethyl)-chalcone) using polyvinyl alcohol nanofibers (PVA) as scaffold. The association of chalcones to the nanofibers was made by nanoemulsions (NE) thereof, i.e., a colloidal system on a nanometric scale, which allows compounds with opposite polarities to remain miscible and stable throughout their manipulation. Chalcone nanoemulsions were developed using the spontaneous emulsification technique. The NE were characterized regarding their particle size, polydispersion index (PDI), and zeta potential. The results showed NE with spherical shape, absolute values of zeta potential were higher than 30 mV and homogeneous distribution pattern (PDI < 0.3). Dynamics light scattering (DLS) analysis showed similar hydrodynamic rays, i.e., 180 nm (trans-chalcone NE) and 178 nm (NE containing 3'-(trifluormethyl)-chalcone, in addition to presenting encapsulation efficiency values close to 100 %. Subsequently, the NE were added to a polymeric solution of polyvinyl alcohol (PVA) and processed via the electrospinning technique affording a PVA matrix (15 %, w/v) nanofiber containing the chalcones NE at 1 mg.mL-1. In a follow-up experiment, the skin permeation assay of the PVA matrix-chalcone NE was performed in vitro using Franz type diffusion cells and porcine ear as biological model of study. The results showed that the treatments with the nanofibers containing the chalcone NE were retained mainly in the stratum corneum, while the NE suspensions containing chalcone were retained in the epidermis and dermis. This result is thought to be relevant, since parasites are located mainly in the dermis. Further, in vitro assay against the amastigote form of L. (L) amazonensis, showed IC50 values to trans-chalcone and 3'-(trifluormethyl)-chalcone of 24.42 ± 6.76 μg.mL-1 and 15.36 ± 4.61 μg.mL-1, respectively. In addition to improving the solubility of the compounds tested in culture medium without using organic solvents, chalcones in nano-emulsified form reduced the IC50 to 9.09 ± 1.24 μg.mL-1 (trans-chalcone) and 10.27 ± 2.27 μg.mL-1 (3'-(trifluormethyl)-chalcone) which confirmed the potential of the nanoemulsion containing chalcone for cutaneous leishmaniasis treatment.

Abstract
This is the first study of the crystal structure of cardamonin (CA) confirmed using single-crystal XRD analysis. In the crystal lattice of CA, two symmetry independent molecules are linked by hydrogen bonds within the layers and by the π···π stacking interactions in the columns which lead to the occurrence of two types of conformations among the CA molecules in the crystal structure. To better understand the stability of these arrangements in both crystals and the gaseous phase, seven different CA dimers were theoretically calculated. The molecular structures were optimized using density functional theory (DFT) at the B3LYP/6–311G+(d,p) level and the spectroscopic results were compared. It was found that the calculated configurations of dimer I and III were almost identical to the ones found in the CA crystal lattice. The calculated UV-Vis spectra for the CA monomer and dimer I were perfectly consistent with the experimental spectroscopic data. Furthermore, enhanced emissions induced by aggregated CA molecules were registered in the aqueous solution with the increase of water fractions. The obtained results will help to further understand the relation between a variety of conformations and the biological properties of CA, and the results are also promising in terms of the applicability of CA as a bioimaging probe to monitor biological processes.

Abstract
A new conjugated carbazole chalcone compound, (E)-3-[4-(9,9a-di-hydro-8aH-carbazol-9-yl)phen-yl]-1-(4-nitro-phen-yl)prop-2-en-1-one (CPNC), C27H18N2O3, was synthesized using a Claisen-Schmidt condensation reaction. CPNC crystallizes in the monoclinic non-centrosymmetric space group Cc and adopts an s-cis conformation with respect to the ethyl-enic double bonds (C=O and C=C). The crystal packing features C-H⋯O and C-H⋯π inter-actions whose percentage contribution was qu-anti-fied by Hirshfeld surface analysis. Quantum chemistry calculations including geometrical optimization and mol-ecular electrostatic potential (MEP) were analysed by density functional theory (DFT) with a B3LYP/6-311 G++(d,p) basis set.
