Abstract
A new set of binuclear arene ruthenium complexes [Ru2(p-cymene)2(k4-N2OS)(L1-L3)Cl2] (Ru2L1-Ru2L3) encompassing furan-2-carboxamide-based aroylthiourea derivatives (H2L1-H2L3) was synthesized and characterized by various spectral and analytical techniques. Single-crystal XRD analysis unveils the N^O and N^S mixed monobasic bidentate coordination of the ligands constructing N, S, Cl/N, O, and Cl legged piano stool octahedral geometry. DFT analysis demonstrates the predilection for the formation of stable arene ruthenium complexes. In vitro antiproliferative activity of the complexes was examined against human cervical (HeLa), breast (MCF-7), and lung (A549) cancerous and noncancerous monkey kidney epithelial (Vero) cells. All the complexes are more efficacious against HeLa and MCF-7 cells with low inhibitory doses (3.86-11.02 μM). Specifically, Ru2L3 incorporating p-cymene and -OCH3 fragments exhibits high lipophilicity, significant cytotoxicity against cancer cells, and lower toxicity on noncancerous cells. Staining analysis indicates the apoptosis-associated cell morphological changes expressively in MCF-7 cells. Mitochondrial membrane potential (MMP) and reactive oxygen species (ROS) analyses reveal that Ru2L3 can raise ROS levels, reduce MMP, and trigger mitochondrial dysfunction-mediated apoptosis. The catalytic oxidation of glutathione (GSH) to its disulfide form (GSSG) by the complexes may simultaneously increase the ROS levels, alluding to their observed cytotoxicity and apoptosis induction. Flow cytometry determined the quantitative classification of late apoptosis and S-phase arrest in MCF-7 and HeLa cells. Western blotting analysis confirmed that the complexes promote apoptosis by upregulating Caspase-3 and Caspase-9 and downregulating BCL-2. Molecular docking studies unfolded the strong binding affinities of the complexes with VEGFR2, an angiogenic signaling receptor, and BCL2, Cyclin D1, and HER2 proteins typically overexpressed on tumor cells.

Synthesis, Characterization, and Investigation of Anti-Inflammatory and Cytotoxic Activities of Novel Thiourea Derivatives of Naproxen. Pharmaceutics 2023; 16:1. [PMID: 38276479 PMCID: PMC10820527 DOI: 10.3390/pharmaceutics16010001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Revised: 12/02/2023] [Accepted: 12/05/2023] [Indexed: 01/27/2024] Open
Abstract
The objective of this study was to synthesize seven novel thiourea derivatives of naproxen (8-14), examine the anti-inflammatory activity of the newly synthesized compounds, investigate the cytotoxic potential of both sets of synthesized compounds (1-7 and 8-14), and select the most promising anti-inflammatory and antitumor drug candidates. The results of the in vivo anti-inflammatory study clearly showed that compounds 8 and 9 were capable of decreasing paw edema, as evident from a high percentage of inhibition (44.83% and 49.29%, respectively). In addition, the results of in vitro enzyme inhibition assays demonstrated that neither of the newly synthesized compounds reached 50% inhibition of 5-LOX at concentrations lower than 100 µM. In terms of antitumor potential, derivatives 3 and 8 exhibited strong cytotoxic effects on the HeLa cell line, suggesting the involvement of the extrinsic pathway of apoptosis. According to the overall results obtained for both sets of synthesized molecules, derivatives 4 and 8 can be underlined as molecules with the strongest anti-inflammatory activity, while derivatives 3 and 8 are the most promising cytotoxic agents.

Abstract
A library of cyclometallated iridium(III) complexes with a strong H-bonding motif in their ancillary ligand was synthesized, characterized and their photophysical properties measured. Demonstrated herein is a general synthetic high yield procedure for these compounds. We ascribe these yields to the use of an intermediary primer ligand. This de novo strategy circumnavigates the standard synthetic issues of H-bond rich ligand precursors (self-aggregation and poor solubility in organic solvents).

Abstract
The aim of the study was a synthesis and investigation of the dose-dependent anti-inflammatory effect of new thiourea derivatives of naproxen with selected aromatic amines and esters of aromatic amino acids. The results of the in vivo study indicate that derivatives of m-anisidine (4) and N-methyl tryptophan methyl ester (7) showed the most potent anti-inflammatory activity four hours after injection of carrageenan, with the percentage of inhibition of 54.01% and 54.12%, respectively. In vitro assays of COX-2 inhibition demonstrated that none of the tested compounds achieved 50% inhibition at concentrations lower than 100 µM. On the other hand, the aromatic amine derivatives (1-5) accomplished significant inhibition of 5-LOX, and the lowest IC50 value was observed for compound 4 (0.30 μM). High anti-edematous activity of compound 4 in the rat paw edema model, together with potent inhibition of 5-LOX, highlight this compound as a promising anti-inflammatory agent.

Abstract
Background
The study of Piszkiewicz’s and Berezin’s models on the redox reaction of allylthiourea and bis-(2-pyridinealdoximato)dioxomolybdate(IV) complex ([MoIVO2(paoH)2]2−) in an aqueous acidic medium is suggested. The Piszkiewicz’s and Berezin’s models are applied, and their parameters are used to explain the redox behaviour of allylthiourea with Mo(IV) complex in the presence of surfactants.
Results
The reaction followed a high cooperativity pattern that reflects a strong interaction between the two redox partners in the presence of cetyltrimethylammonium bromide (CTAB) which is reinforced by a notable binding constant at the Stern layer of the micelle. The effect of cationic counter-ion (Ca2+) on the reaction rate further confirmed the effectiveness of the interaction at the rate-limiting step. The presence of sodium dodecyl sulphate (SDS) in the reaction medium resulted in reaction inhibition which reveals the interplay of electrostatic repulsion at the electrophilic polar head of the surfactant and the redox species. The effect of ionic strength on the reaction rate shows that one of the reacting species is not charged (neutral) which kept the rate of the reaction uniform at different salt concentrations studied. The change in the medium polarity buttressed the effect of ionic strength on the reaction which is explained better by Piszkiewicz’s and Berezin’s models. Free radical was actively engaged in the reductive process of the Mo(IV) complex, and this revealed that the hydrophobic region is a possible location for the interaction of the redox partner in the presence of SDS micelle.
Conclusions
The models depict well the microenvironments of enzymatic reactions involving bimolecular interactions with significant binding constants and cooperativity indexes that show the strength of the interaction between the substrates and surfactant molecules.

Abstract
Cancer is a disease that starts from the uncontrolled growth of abnormal cells in the organs or tissues of the body, which is the second leading cause of death in the world. One of the targets in discovering and developing anticancer drugs is Sirtuin-1. SIRT1 can act as a tumor suppressor or tumor promoter depending on its target in a particular signalling pathway or on particular cancer. This study aimed to study the interaction of a thiourea derivative with SIRT1 (PDB ID:4I5I) through its inhibition of histone deacetylase. Research has been carried out in silico with molecular docking (MGLTools.1.5.6) and molecular dynamics (Desmond 2019) of three thiourea derivatives to the receptor. In addition, pharmacokinetic parameters, toxicity, and selection of Lipinski's Rule of Five were also tested. Molecular docking results showed that compound b ([2-(methylcarbamothioylcarbamoyl)phenyl]benzoate) had the lowest ∆G value of −9.29 kcal/mol with a KI value of 0.156 µM compared to other thiourea derivatives and was proven by molecular dynamics tests for 30 ns and amino acids that play an active role in the interaction include the residue PheA:297. In terms of pharmacokinetics and toxicity, compound b is better than natural ligands. Compound b is predicted to be used as an anticancer candidate through further research.

Abstract
Novel benzoylthioureas, N-((5-chloropyridin-2yl)carbamothioyl)benzamide, (HL1), N-((2-chloropyridin-3yl)carbamothioyl)benzamide, (HL2), N-((5-bromopyridin-2yl)carbamothioyl)benzamide, (HL3) and N-(Naphthalene-1-yl(phenyl)carbamothioyl)benzamide, (HL4), were synthesized. Their characterizations were made by FT-IR,1H NMR and 13C NMR spectrophotometric analysis. Single crystal X-ray diffraction measurements were conducted to determine the crystal structure of HL1 and HL4. The HL1 crystallization conditions are: in the monoclinic crystal system with P21/c space group, Z = 2, a = 8.118(2) Å, b = 12.056(3) Å, c = 13.753(4) Å. HL4crystallization conditions are: in the orthorhombic crystal system with Pbca space group, Z = 8, a = 19.597(9) Å, b = 8.270(4) Å, c = 24.299(11) Å. Investigation of photodynamic and antiinflamatory effects of these compounds revealed that they are potent adducts. Using these derivatives, mammalian macrophages were stimulated with LPS to test their anti-inflammatory activity. Based on pro-inflammatory cytokine production levels, the photodynamic anti-inflammatory activity of these adducts were found to differ. Our results showedthat benzoylthioureas can be used as potential photodynamic therapy agents to suppress the excessive inflammatory reactions encountered in autoimmune and inflammatory disorders.

Abstract
The 1,3-dipolar cycloaddition between azides and alkynes provides new means to probe and control biological processes. A major challenge is to achieve high reaction rates with stable reagents. The optimization of alkynyl reagents has relied on two strategies: increasing strain and tuning electronics. We report on the integration of these strategies. A computational analysis suggested that a CH → N aryl substitution in dibenzocyclooctyne (DIBO) could be beneficial. In transition states, the nitrogen of 2-azabenzo-benzocyclooctyne (ABC) engages in an n→π* interaction with the C=O of α-azidoacetamides and forms a hydrogen bond with the N-H of α-diazoacetamides. These dipole-specific interactions act cooperatively with electronic activation of the strained π-bond to increase reactivity. We found that ABC does indeed react more quickly with α-azidoacetamides and α-diazoacetamides than its constitutional isomer, dibenzoazacyclooctyne (DIBAC). ABC and DIBAC have comparable chemical stability in a biomimetic solution. Both ABC and DIBO are accessible in three steps by the alkylidene carbene-mediated ring expansion of commercial cycloheptanones. Our findings enhance the accessibility and utility of 1,3-dipolar cycloadditions and encourage further innovation.

High pressure assisted synthetic approach for novel 6,7-dihydro-5H-benzo[6,7]cyclohepta[1,2-b]pyridine and 5,6-dihydrobenzo[h]quinoline derivatives and their assessment as anticancer agents. Sci Rep 2020; 10:21691.

Abstract
A novel, expedient and effective methodology for the synthesis of distinctly substituted 6,7-dihydro-5H-benzo[6,7]cyclohepta[1,2-b]pyridine and 5,6-dihydrobenzo[h]quinoline systems has been developed with a new synthetic platform. This process includes ammonium acetate-mediated cyclocondensation reactions of 3-oxo-2-arylhydrazonopropanals with benzosuberone and tetralone precursors, respectively, using the high-pressure Q-tube reactor, which has been found to be superior to both conventional heating and microwave irradiation. The novel protocol benefits from its high atom efficiency, economy, ease of workup, broad substrate scope and is also applicable to gram-scale synthesis. To identify and confirm the newly synthesized targeted compounds, the X-ray single-crystal as well as all possible spectroscopic methods were utilized. The cytotoxicity of the newly synthesized 6,7-dihydro-5H-benzo[6,7]cyclohepta[1,2-b]pyridine 4a-j and 5,6-dihydrobenzo-[h]quinolines derivatives 6a-e were preliminary examined toward three cell lines of human cancer; lung cancer (A549), breast cancer (MCF-7) and colon cancer (HCT-116), by applying the MTT colorimetric assay. The achieved results reflected the promising profile of the prepared compounds in this study against cancer cells and have shown that members from the synthesized 6,7-dihydro-5H-benzo[6,7]cyclohepta[1,2-b]pyridine 4a-j exhibited promising cytotoxicity's against MCF-7, and A549 cancer cells respectively, while the HCT-116 (colon) cancer cells were inhibited by certain examples of 5,6-dihydrobenzo[h]quinoline derivatives 6c,d. These promising results could serve as a good primary base for further research into the design of anticancer drugs.

Abstract
The title compound, C26H31N3O2S, crystallizes with two molecules (A and B) in the asymmetric unit. In each case, the piperidine ring exists in a twist-boat conformation. The dihedral angle between the phenyl rings is 46.16 (12)° in molecule A and 44.95 (12)° in molecule B. In both molecules, the allyl side chain is disordered over two orientations in a 0.649 (9):0.351 (9) ratio for molecule A and 0.826 (10):0.174 (10) ratio for molecule B. In the crystal, neither molecule forms a hydrogen bond from its N—H group, presumably due to steric hindrance. A+A and B+B inversion dimers are formed, linked by pairs of weak C—H⋯O hydrogen bonds enclosing R22(22) ring motifs.

Abstract
Novel derivatives were prepared by reaction of aromatic amines with 2-(4-ethylphenoxymethyl)benzoyl isothiocyanate, affording the N-[2-(4-ethylphenoxymethyl) benzoyl]-Nꞌ-(substituted phenyl)thiourea. Structural elucidation of these compounds was performed by IR, NMR spectroscopy and elemental analysis. The new compounds were used in combination with Fe3O4 and polyvinylpyrrolidone (PVP) for the coating of medical surfaces. In our experiments, catheter pieces were coated by Matrix Assisted Pulsed Laser Evaporation (MAPLE) technique. The microbial adherence ability was investigated in 6 multi-well plates by using culture based methods. The obtained surfaces were also assessed for their cytotoxicity with respect to osteoblast cells, by using fluorescence microscopy and MTT assay. The prepared surfaces by advanced laser processing inhibited the adherence and biofilm development ability of Staphylococcus aureus and Pseudomonas aeruginosa tested strains while cytotoxic effects on the 3T3-E1 preosteoblasts embedded in layer shaped alginate hydrogels were not observed. These results suggest that the obtained medical surfaces, based on the novel thiourea derivatives and magnetic nanoparticles with a polymeric shell could represent a promising alternative for the development of new and effective anti-infective strategies.

Abstract
A number of 2-((4-ethylphenoxy)methyl)-N-(substituted-phenylcarbamothioyl) benzamides (1a–h) were synthesized via reaction of 2-((4-ethylphenoxy)methyl)benzoyl isothiocyanate (2) as a key intermediate with several substituted primary aromatic amines. The new compounds were characterized by proton nuclear magnetic resonance (1H-NMR), carbon-13 nuclear magnetic resonance (13C-NMR), infrared spectrometry (IR), mass spectrometry (MS), and elemental analysis. The anti-inflammatory activity of 1a–h was investigated by acute carrageenan-induced paw edema in mice using the reference drug indomethacin. The results obtained indicated that, of the derivatives developed, 1a and 1d–h exhibited significantly higher anti-inflammatory activity (26.81%–61.45%) when compared with the reference drug indomethacin (22.43%) (P = 0.0490 for 1a, 0.0015 for 1d, 0.0330 for 1f, and P < 0.001 for 1e and 1h). Moreover, the ulcer incidence of 20% for 1e and 1h was clearly lower when compared with the indomethacin group (in which the ulcer incidence was 80%). Of particular note, the ulcer index of 0.2 for 1e was significantly less than that in the indomethacin group (0.6, P = 0.014). Additionally, prostaglandin E2 (PGE2) inhibitory properties were found to be high with 1e (68.32 pg/mL), significantly different from those of the placebo group (530.13 pg/mL, P < 0.001), and equipotent to the effect observed in the indomethacin-pretreated group (96.13 pg/mL, P > 0.05). Moreover, the PGE2 level of 54.15 pg/mL with 1h was also significantly different from that of the placebo group (P < 0.001) and of the indomethacin group (P < 0.05). The significant inhibition of PGE2 observed with 1e (68.32 pg/mL) and 1h (54.15 pg/mL) agree with their observed ulcer incidences. Our overall findings for N-phenylcarbamothioylbenzamides 1a–h clearly suggest that the compounds exhibit an anti-inflammatory effect, potently inhibit PGE2 synthesis, and markedly demonstrate low ulcer incidence.

Abstract
Several phenylethyl-substituted pyridinecarboxaldehydes were prepared from 2-bromo-3-pyridinecarboxaldehyde and these substances are found to undergo cyclization reactions in acidic media. In the absence of added nucleophile, acid promoted cyclization and oxidation (MnO2) provides an efficient route to 10,11-dihydro-5H-benzo[4,5]cyclohepta[1,2-b]pyridin-5-ones. Arene nucleophiles may also be added to the acidic mixture to provide good yields of triarylmethane products. Mechanisms are proposed involving dicationic superelectrophilic intermediates.

Abstract
Cyanoguanidine derivatives of loratadine (3a-i) were synthesized and screened for antitumor and anti-inflammatory activity. The most promising compound 3c (R=n-C(8)H(17)) possessed at least twofold higher in vitro cytotoxicity than 5-fluorouracil against mammary (MCF-7 and MDA-MB 231) as well as colon (HT-29) carcinoma cells. The mode of action, however, is so far unclear. The participation of the COX-1/2 enzymes on the cytotoxicity, however, is very unlikely. Nevertheless all compounds showed stronger in vivo anti-inflammatory activity than ibuprofen in the xylene-induced ear swelling assay in mice.
