, p. 2585 - 2592 (2003)
One pot reaction of benzoyl isothiocyanate and Tris(hydroxymethyl)aminomethane (Tris) at room temperature with polyethylene glycol-400 (PEG-400) as solid-liquid phase-transfer catalyst produced substituted N-benzoylthioureas with high yield. A reasonable pathway for their formation has been suggested.

A series of N-(benzo[d]oxazol-2-ylcarbamothioyl)-2/4-substituted benzamides were synthesized by the reaction of 2-aminobenzoxazole with apposite benzoyl isothiocyanate. The structure of the newly synthesized compounds was confirmed by chemical tests, elemental (C, H, N, and S), and spectral (IR, 1H NMR, 13C NMR, and mass) analysis. All the synthesized compounds were evaluated experimentally for their antibacterial activity against Gram-positive and Gram-negative bacteria. The test results show moderate to potent antibacterial activity compared to the standard drug. The binding interactions of newly synthesized ligand and protein were correlated using a molecular docking study using a binding pocket of GlcN-6-P synthase. [Figure not available: see fulltext.].

A new series of bis-thioureas (4a-4j) was synthesized and characterized through spectroscopic and elemental analysis. The synthesized compounds 4a-4j were subjected to acetylcholinesterase enzyme (AChE) inhibition activity and free radical scavenging activity. The results of AChE inhibition assay were found to be active in inhibiting the target enzyme with different IC50 values. Among all derivatives, the 4 g showed highly potent inhibition potential against AChE enzyme with IC50 value of 0.1761±0.00768 μM, which is several times better than the reference inhibitor neostigmine methylsulfate IC50 2.469±0.069 μM. The initial structure-activity relationship (SAR) of 4 g revealed dual hydrogen bonding ability (donor and acceptor). Moreover, the electronic environment around the aromatic ring also greatly influenced the enzyme inhibition of AChE. To further explore the newly synthesized AChE inhibitors, kinetic studies were carried out to determine the mode of inhibition and it was found to be competitive inhibition. Pharmacokinetic predictions (ADMET parameters) were also evaluated and compounds showed good lead-like potential with little hepatotoxic and no skin-sensitive effects. The molecular docking studies delineated the binding affinity of the ligands with target protein and showed docking scores in the range of -10.3 to -7.6 kcal/mol.

The present work describes an efficient and convenient synthesis of a library of novel 3-(substituted benzoyl)-2-thioxoimidazolidin-4-ones (3a–j). The benzoyl isothiocyanates were treated with glycine in the presence of pyridine, the reactants got consumed giving a variety of thioxoimidazolidin-4-ones derivatives under mild reaction conditions. The structures of the compounds were determined by elemental analysis, FTIR, 1H, 13C NMR and mass spectral data. The title compounds were tested for their potential to inhibit the activity of enzymes α-glucosidase and α-amylase. It was found that most of the derivatives showed good enzyme inhibitory activity while compound 3j exhibited excellent activity with IC50 values 0.051 and 0.0082 mM for α-glucosidase and α-amylase, respectively. The presence of 3,5-di-NO2 functional groups at aromatic ring in compound 3j play important role in enzyme inhibitory activity. The enzyme inhibitory kinetic analysis of the most potent derivative 3j revealed that it is a mixed type inhibitor of α-glucosidase with Ki and Ki? values 0.0339 and 0.1562 mM, respectively. It was further investigated that compound 3j formed reversible enzyme inhibitor complex with α-glucosidase. The cytotoxicity of all the synthesized compounds was also evaluated and results showed that none of these compounds displayed toxicity against brine shrimps. Based upon results, it is suggested that compound 3j may act as a lead structure for the development of most potent α-glucosidase inhibitors.

Aroylthiourea derivatives of ciprofloxacin drug — [1-cyclopropyl-6-fluoro-7-(4-((4-methoxybenzoyl)carbamothioyl)piperazin-1-yl)-4-oxo-1,4-dihydroquinoline-3-carboxylic acid] ATU-1, [1-cyclopropyl-7-(4-((2,4-dibromobenzoyl)carbamothioyl)piperazin-1-yl)-6-fluoro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid] ATU-2, and [1-cyclopropyl-7-(4-((3,5-dinitrobenzoyl)carbamothioyl)piperazin-1-yl)-6-fluoro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid] ATU-3 were synthesized, characterized and investigated for DNA binding at stomach pH (4.7) and at 37 °C. All findings by using DFT, molecular docking, spectroscopic (UV-, fluorescence; FL-), cyclic voltammetric (CV) and viscometric techniques revealed that these compounds have the potency to bind with DNA via a mixed mode of interaction. The binding affinity of ATU-1 was evaluated comparatively greater with Kb × 104/M?1 (docking; 5.55, UV-; 7.93, FL-; 5.62, CV; 6.06), ΔG/kJmol?1(docking; ?27.07, UV-; ?29.07, FL-; ?28.18, CV; ?28.38) and n (FL-; 1.20, CV; 2.72). Stern-Volmer quenching constant (Ksv) further pointed towards comparatively greater binding affinity of ATU-1 for DNA, while bimolecular quenching constant (Kq) values showed the involvement of static quenching mechanism in the compound — DNA interaction. Comparatively lesser IC50 (7.1 μM) value obtained from biological work on Huh-7 cancer cell line further confirmed the greater anticancer potential of ATU-1 than that of ATU-2&3.
