Res Pharm Sci 2023; 18:371-380. [PMID: 37614619 PMCID: PMC10443667 DOI: 10.4103/1735-5362.378084] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Revised: 08/15/2022] [Accepted: 05/03/2023] [Indexed: 08/25/2023] Open
Abstract
Background and purpose The incidence of antibiotic resistance rapidly emerges over the globe. In the present study, the synthesis of thiourea derivatives as antibacterial agents and their biological evaluation are reported. Experimental approach Preliminary studies were done by molecular docking of four analogs of 1-allyl-3-benzoylthiourea, clorobiocin, and ciprofloxacin on the DNA gyrase subunit B receptor (PDB: 1KZN). The nucleophilic substitution reaction of benzoyl chloride analogs to the allylthiourea yielded four 1-allyl-3-benzoylthiourea analogs (Cpd 1-4). The reactions were done by a modified Schotten Baumann method. The in vitro antimicrobial activities were determined using the agar dilution method against methicillin-resistant Staphylococcus aureus (MRSA), Salmonella typhi, Escherichia coli, and Pseudomonas aeruginosa. Findings/Results The in-silico study showed that Cpd 1-4 possesses a good interaction on the DNA gyrase subunit B receptor compared to the ciprofloxacin. Cpd 3 had the best binding affinity with a rerank score of - 91.2304. Although the candidate compounds showed unsatisfactory antibacterial activity, they indicated an increasing trend of growth inhibition along with the increment of concentration. Cpd 1 and 4 exhibited in vitro antibacterial activities against MRSA with a minimum inhibitory concentration value of 1000 µg/mL, better compared to the other compounds. Conclusion and implication Despite lacking antibacterial activity, all the synthesized compounds showed an increased trend of growth inhibition along with the increment of concentration. Therefore, additional development should be implemented to the compounds of interest in which optimization of lipophilicity and steric properties are suggested.

Antimycobacterial and anti-inflammatory activities of thiourea derivatives focusing on treatment approaches for severe pulmonary tuberculosis. Bioorg Med Chem 2022; 53:116506. [PMID: 34890996 DOI: 10.1016/j.bmc.2021.116506] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2021] [Revised: 11/01/2021] [Accepted: 11/02/2021] [Indexed: 12/13/2022]
Abstract
Tuberculosis (TB) remains a serious public health problem and one of the main concern is the emergence of multidrug-resistant and extensively resistant TB. Hyper-reactive patients develop inflammatory necrotic lung lesions that aggravate the pathology and facilitate transmission of mycobacteria. Treatment of severe TB is a major clinical challenge that has few effective solutions and patients face a poor prognosis, years of treatment and different adverse drug reactions. In this work, fifteen novel and thirty-one unusual thiourea derivatives were synthesized and evaluated in vitro for their antimycobacterial and anti-inflammatory potential and, in silico for ADMET parameters and for structure-activity relationship (SAR). Thioureas derivatives 10, 15, 16, 28 and 29 that had shown low cytotoxicity and high activities were selected for further investigation, after SAR study. These five thioureas derivatives inhibited Mtb H37Rv growth in bacterial culture and in infected macrophages, highlighting thiourea derivative 28 (MIC50 2.0 ± 1.1 and 2.3 ± 1.1 µM, respectively). Moreover, these compounds were active against the hypervirulent clinical Mtb strain M299, in bacterial culture, especially 16, 28 and 29, and in extracellular clumps, highlighting 29, with MIC50 5.6 ± 1.2 µM. Regarding inflammation, they inhibited NO through the suppression of iNOS expression, and also inhibited the production of TNF-α and IL-1β. In silico studies were carried out suggesting that these five compounds could be administered by oral route and have low toxicological effects when compared to rifampicin. In conclusion, our data show that, at least, thiourea derivatives 16, 28 and 29 are promising antimycobacterial and anti-inflammatory agents, and candidates for further prospective studies aiming new anti-TB drugs, that can be used on a dual approach for the treatment of severe TB cases associated with exacerbated inflammation.

Abstract
A new series of urea/thiourea derivatives have been efficiently synthesized from the reaction of L-3-hydroxytyrosine with selective isocyanates/isothiocyanates and characterized by Infra-red, proton & carbon-13 nuclear magnetic resonance spectral and mass spectrometry studies. All the synthesized compounds have been screened for their antioxidant activity by 1,1-diphenyl1-2-picrylhydrazyl radical assay, ferric reducing antioxidant power assay and also studied their molecular docking interaction profiles against 1N8Q and 3NRZ enzymatic proteins. The in vitro antioxidant activity has further supported by quantitative structure activity relationship, absorption, distribution, metabolism, and excretion & toxicity studies, bioactivity studies & enzyme inhibition assay and identified that they were potentially bound to ASP490 & ASP361 aminoacid residue in chain A of 1N8Q protein and GLN1194 aminoacid residue in chain L of 3NRZ protein and are responsible for potential antioxidant activity. It is proved that urea derivatives linked with 4-fluoro & 4-nitro and thiourea derivatives linked with 3-chloro & 4-fluoro have exhibited promising antioxidant activity. In eventual synthesized compounds have been identified as potential blood-brain barrier penetrable compounds and proficient central nervous system active neuro-protective antioxidant agents as they have envisaged as easily penetrable to blood-brain barrier thresholds, a neuroprotective property.

Abstract
A series of novel α-methyl-l-DOPA urea derivatives viz., 3-(3,4-dihydroxyphenyl)-2-methyl-2-(3-halo/trifluoromethyl substituted phenyl ureido)propanoic acids (6a-e) have been synthesized from the reaction of α-methyl-l-DOPA (3) with various aryl isocyanates (4a-e) by using triethylamine (5, TEA) as a base catalyst in THF at reflux conditions.

Abstract
Synthesis of a series of new urea and thiourea compounds have been accomplished by the reaction of 2,3-dihydro-1H-inden-1-amine with various phenyl isocyanates and isothiocyanates. These compounds were evaluated for their antioxidant activity by using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and nitric oxide (NO) radical scavenging assay methods including IC50 values. Some of the compounds exhibited potential activity in the two tested methods. Among the series of compounds, urea derivative linked with 4-bromo phenyl ring (4b), and thiourea derivatives bonded with phenyl ring (4e), 4-fluoro phenyl ring (4f) and 4-nitro pheyl ring (4h) were found to exhibit promising anti oxidant activity with low IC50 values. Where four of the title comounds exhibited higher bindig energies than the reference compound (Imatinib) in in silico molecular docking studies with Aromatase. All the synthesized compounds were characterized by IR, 1H, 13C NMR and mass spectral data.

Abstract
A series of 1-(2,3-dihydro-1H-indan-1-yl)-3-aryl urea/thiourea derivatives (4a-j) have been synthesized from the reaction of 2,3-dihydro-1H-inden-1-amine (2) with various aryl isocyanates/isothiocyanates (3a-j) by using N,N-DIPEA base (Hunig's base) catalyst in THF at reflux conditions. All of them are structurally confirmed by spectral (IR, 1H &13C NMR and MASS) and elemental analysis and screened for their in-vitro antioxidant activity against DPPH and NO free radicals and found that compounds 4b, 4i, 4h &4g are potential antioxidants. The obtained in vitro results were compared with the molecular docking, ADMET, QSAR and bioactivity study results performed for them and identified that the recorded in silico binding affinities were observed in good correlation with the in vitro antioxidant results. The Molecular docking analysis had unveiled the strong hydrogen bonding interactions of synthesized ligands with ARG 160 residue of protein tyrosine kinase (2HCK) enzyme and plays an effective role in its inhibition. Toxicology studies have assessed the potential risks of 4a-j and inferred that all of them were in the limits of potential drugs. The conformational analysis of 4a-j inferred that the urea/thiourea spacer linking 2,3-dihydro-1H-inden-1-amino and substituted aryl units has facilitated all these molecules to effectively bind with ARG 160 amino acid residue present on the α-helix of the protein tyrosine kinase (2HCK) enzyme specifically on chain A of hemopoetic cell kinase. Collectively this study has established a relationship between the antioxidant potentiality and ligands binding with ARG 160 amino acid residue of chain A of 2HCK enzyme to inhibit its growth as well as proliferation of reactive oxygen species in vivo.
