Abstract
The 1-acyl thiourea family [R1C(O)NHC(S)NR2R3] exhibits the flexibility to incorporate a wide variety of substituents into their structure. The structural attributes of these compounds are intricately tied to the type and extent of substitution. In the case of 3-mono-substituted thioureas (R2=H), the conformational behavior is predominantly shaped by the presence of an intramolecular N-H ⋅ ⋅ ⋅ O=C hydrogen bond. This study delves into the structural consequences stemming from the inclusion of substituents possessing hydrogen-donor capabilities within four novel 1-acyl-3-mono-substituted thiourea derivatives. A comprehensive suite of analytical techniques, encompassing FTIR, Raman spectroscopy, multinuclear (1H and 13C) NMR spectroscopy, single-crystal X-ray diffraction, and supported by computational methods, notably NBO (Natural Bond Orbital) population analysis, Hirshfeld analysis, and QTAIM (Quantum Theory of Atoms in Molecules), was harnessed to scrutinize and characterize these compounds. In the crystalline state, these compounds exhibit an intricate interplay of intermolecular interactions, prominently featuring an expansive network of hydrogen bonds between the hydroxy (-OH) groups and the carbonyl and thiocarbonyl bonds within the 1-acyl thiourea fragment. Notably, the topological analysis underscores significant distinctions in the properties of the acyl thiourea fragment and the intramolecular >C=O ⋅ ⋅ ⋅ H-N bond when transitioning from the isolated molecule to the crystalline environment.

Hassan HHAM, ELhusseiny AF. A new antimicrobial PVC-based polymeric material incorporating bisacylthiourea complexes. BMC Chem 2023; 17:44. [PMID: 37138320 PMCID: PMC10157947 DOI: 10.1186/s13065-023-00958-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Accepted: 04/24/2023] [Indexed: 05/05/2023] Open
Abstract
A new antimicrobial material incorporating Cu(I) and Cd(II) complexes of bisacylthiourea derivatives in a PVC film was successfully synthesized and characterized by IR, UV, NMR, SEM, and thermal analyses. The results revealed that on coordination, the electronic structure change of the ligand affects practically all their spectral vibrational pattern; however, within the complex pattern, some vibrations indicated that the thiourea derivative behaves as a neutral ligand, which coordinates the metal ion through the sulfur atom of the thiocarbonyl group. The greater affinity of the S atom for Cu+ 1 played a role in Cu(II)→Cu(I) reduction, and the intramolecular hydrogen bonds of the type of (NH···Cl) further stabilized the obtained Cu(I) complex in dioxane. The antimicrobial activity shows that all investigated compounds exhibit excellent activity compared to standard antibiotics. The antibacterial power of the PVC/Cd composite is significantly superior against the most resistant species to both disinfectants and antibiotics compared to its PVC/Cu analogue; nevertheless, the latter exhibited activity equal to an average halo diameter of 29 ± 0.33 mm against pathogenic E. coli ATCC 25,922, indicating excellent G (-) activity. Interestingly, the PVC/Cd composite exhibited excellent activity against pathogenic C. albicans RCMB 005003 (1) ATCC 10,231, while its PVC/Cu analogue was inactive. These materials may be used to reduce infection in wounds either as a composite film or coated barrier dressings, and in addition, the results should open a new direction in antimicrobial surface engineering within the biomedical field. Further challenges are the development of reusable and broad-range antimicrobial polymers..

Abstract
Background:
Local anesthetics are widely used to decrease sensitivity to pain in specific regions of the body while performing medical tasks. Many studies have probed the mechanism of action of local anesthetics but still many questions remain. (2R - (-) 2 - (2, 6-dimethylphenylaminocarbonyl) - 1 – methyl piperidinium chloride (DAMP), is an extensively used amide-type local anesthetic.
Objective:
This study aims at revealing the various electrophysical and chemical properties of the title compound. This study will be useful for future research by pharmacologists.
Method:
Density Functional Theory (DFT) computations were executed using Gaussian’09 program package and were optimized with the B3LYP /6-311+G (d, p) basis set. Natural bond orbital (NBO) analysis was carried out with version 3.1. Normal Coordinate Analysis (NCA) was used to systematically calculate the harmonic vibrational wavenumbers. Molecular docking simulations were carried out to understand the pharmacokinetic behavior of the drug.
Results:
The presence of strong N-H…Cl intra molecular hydrogen bonding was evidently revealed from the FT-IR spectrum due to the shifting of NH stretching wavenumber. Stability of the molecule arising from hyper conjugative interactions exhibits the bioactivity of the molecule by natural bond orbital analysis. The title molecule binds to the inner pore and blocks voltage - gated sodium channels in peripheral neurons.
Conclusion:
A detailed molecular picture of DAMP and its interactions were obtained by modeling analysis, IR, Raman, and UV-Vis spectroscopy. The geometrical parameters agree well with the XRD data. NBO analysis indicates the bioactivity of the molecule. The HOMO-LUMO energy gap indicates the possibility of intramolecular charge transfer of the molecule. From the ligand docking studies it is concluded that the title molecule binds to the inner pore and blocks voltage - gated sodium channels in peripheral neurons.

Abstract
The title compound, C6H11NO3S, provides entries to novel carbamoyl disulfanes and related compounds of inter-est to our laboratory. The atoms of the central O(C=S)N(C=O)O fragment have an r.m.s. deviation of 0.1077 Å from the respective least-squares plane. While several conformational orientations are conceivable, the crystal structure shows only the one in which the carbonyl and the thio-carbonyl moieties are anti to each other across the central conjugated C-N-C moiety. Pairs of 2.54 Å N-H⋯S=C hydrogen bonds between adjacent mol-ecules form centrosymmetric dimers in the crystal.

Abstract
A new isomers of thiourea derivatives, namely N-(4-chlorobutanoyl)-N'-(2-methylphenyl)-thiourea (1a), N-(4-chlorobutanoyl)-N'-(3-methylphenyl)thiourea (1b) and N-(4-chlorobutanoyl)-N'-(4-methylphenyl)thiourea (1c) have been synthesized by refluxing mixture of equimolar amounts of 4-chlorobutanoylisothiocyanate with 2, 3 or 4-toluidine, respectively. The three isomers were characterized by spectroscopic (UV/vis, FT-IR and NMR) and X-ray crystallography techniques. To investigate the isomerization effect on spectroscopic data, DFT and TD-DFT calculations have been carried out using five hybrid functionals (B3LYP, B3P86, CAM-B3LYP, M06-2X and PBE0) to predict UV/vis absorption bands (n→π∗ and π→π∗), (1)H and (13)C NMR chemical shifts, FT-IR vibration modes and X-ray parameters (bonds, bond angles and torsion angles) for 1a, 1b and 1c isomers. The results showed that the isomerization effect is significant on λ(MAX) absorption bands, while for IR and NMR the effect is negligible. In accordance with previous studies, B3LYP, B3P86 and PBE0 gave the most reliable to predict the excitation energies of thiourea derivatives.

Abstract
1-(Adamantane-1-carbonyl)-3-(2,4-dichlorophenyl)thiourea (1) and 1-(adamantane-1-carbonyl)-3-(2-bromo-4,6-difluorophenyl)thiourea (2) were synthesized by the reaction of adamantane-1-carbonyl chloride with ammonium thiocyanate to afford the adamantane-1-carbonylisothiocyanate in situ followed by treatment with suitable halogenated anilines. The structures of the products were established by elemental analyses, Fourier transform infrared spectroscopy (FTIR), (1)H, (13)C nuclear magnetic resonance (NMR), mass spectroscopy and single crystal X-ray diffraction study. Bond lengths and angles show the usual values. All of three condensed cyclohexane rings of the adamantane residues adopt the usual chair conformation. The molecular conformation of 1 and 2 is stabilized by an intramolecular (NH⋯OC) hydrogen bond which forms a pseudo-six-membered ring. Structural features have been complemented with the joint analysis of the FTIR and FT-Raman spectra along with quantum chemical calculations at the B3LYP/6-311++G level.

Abstract
FT-Raman and IR spectra of the herbicidal compound chlorbromuron have been recorded and analyzed. The detailed interpretation of the vibrational spectra has been carried out with the aid of normal coordinate analysis (NCA) following the scaled quantum mechanical force field methodology. The various intramolecular interactions which are responsible for the stabilization of the molecule were revealed by natural bond orbital analysis. The Mulliken population analysis on atomic charges and the HOMO-LUMO energy were also calculated. The presence of strong NH⋯O intermolecular hydrogen bonding was clearly exposed from the IR spectrum by the red shifting of NH stretching wavenumber.

Abstract
Abstract
The crystal structure of 4-ethyl-5-(2-thienyl)-2,4-dihydro-3H-1,2,4-triazole-3-thione (1) was determinäed. The compound crystallizes in the monoclinic space group P21/n (Z = 4) with a = 8.679(2), b = 7.873(2), c = 14.657(3) Å, β = 105.56(3)° and V = 964.8(4) Å3. Its molecular and crystal structure was compared with three aromatic analogs. In three crystal structures of 2,4-dihydro-3H-1,2,4-triazole-3-thione derivatives, Ntriazole—H · · · S(=C) dimer as the main structural motif is formed, while in one Ntriazole—H · · · S hydrogen bonds connect molecules to make helix arrangement. Moreover, in 1, Cethyl—H · · · S(=C), Sthione · · · Sthiophene and πthiophene · · · πtriazole interactions are observed; there are not N—H · · · N hydrogen bonds.
NMR in DMSO and IR experiments confirmed the compound to exist as the thione tautomer.
We carried out extensive conformational searches for 1 at the molecular mechanics level in order to compare structures obtained from different force fields with the experimental results.
