Eur J Med Chem 2022; 238:114420. [PMID: 35594653 DOI: 10.1016/j.ejmech.2022.114420] [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: 12/24/2021] [Revised: 04/21/2022] [Accepted: 04/26/2022] [Indexed: 11/30/2022]
Abstract
Based on the previous synthesis of tetracyclic and tricyclic benzimidazoles starting from 1,4:3,6-dianhydro-d-fructose and o-phenylenediamines, a series of 5(6)-amino substituted tetracyclic and tricyclic benzimidazolequinones were obtained through the oxidation of 4,7-dimethoxy-benzimidazole analogues with bis(trifluoroacetoxy)iodobenzene (PIFA) and subsequent substitution with various aliphatic and aromatic amines. Biological evaluations of the target benzimidazolequinones indicated that all the arylamino-substituted benzimidazolequinones possess potent antitumour activity against human gastric cancer cells (MGC-803), especially compound a21-2. Furthermore, compound a21-2 inhibits gastric cancer cells proliferation and cell colony formation. Mechanistic investigations showed that compound a21-2 induces ROS production, which subsequently causes DNA damage and activation of ATM/Chk2, leading to G2/M phase arrest. ROS activates the c-Jun N-terminal kinase (JNK) pathway to induce mitochondrial-mediated apoptosis. In vivo studies showed that compound a21-2 inhibits the growth of tumours in nude mice without significant systemic toxicity. These findings suggest that compound a21-2 represents a promising candidate antitumour drug.

Abstract
Herein, the design and synthesis of new 2-phenyl(pyridinyl)benzimidazolequinones and their 5-phenoxy derivatives as potential anti-Trypanosoma cruzi agents are described. The compounds were evaluated in vitro against the epimastigotes and trypomastigote forms of Trypanosoma cruzi. The replacing of a benzene moiety in the naphthoquinone system by an imidazole enhanced the trypanosomicidal activity against Trypanosoma cruzi. Three of the tested compounds (11a-c) showed potent trypanosomicidal activity and compound 11a, with IC50 of 0.65 μM on the trypomastigote form of T. cruzi, proved to be 15 times more active than nifurtimox. Additionally, molecular docking studies indicate that the quinone derivatives 11a-c could have a multitarget profile interacting preferentially with trypanothione reductase and Old Yellow Enzyme.

Abstract
β-Bromo-α,β-unsaturated aldehydes and 2-bromobenzaldehydes react with 4,7-dimethoxy-1H-benzo[d]imidazole-2-amine by microwave irradiation in dimethylformamide in the presence of a base to give the corresponding dimethoxy-substituted benzo[4,5]imidazo[1,2-a]pyrimidines and benzo[4,5]imidazo[1,2-a]quinazolines, respectively, in moderate to good yields. Oxidation of such N-fused hybrid scaffolds by aqueous ceric ammonium nitrate affords pyrimidine- and quinazoline-fused benzimidazole-4,7-diones in high yields.

Abstract
The current study evaluates antidiabetic, anticoagulant, and antiplatelet activity of novel benzimidazole-containing quinolinyl oxadiazoles. These derivatives are synthesized and characterized using spectroscopy (FT-IR, 1H NMR, and mass spectroscopy) and single-crystal X-ray diffraction methods. The inhibitory effects of these compounds were evaluated by the α-glucosidase inhibitory assay and shows the activity in the range of IC50 = 0.66 ± 0.05 to 3.79 ± 0.46 μg/mL. In addition, molecular docking studies revealed that benzimidazole-containing quinolinyl oxadiazoles can correctly dock into the target receptor protein of the human intestinal α-glucosidase, while their bioavailability/drug-likeness was predicted to be acceptable but requires further optimization. On the other hand, compound 8a and 8d showed anticoagulant activity as they enhanced the clotting time from control 180-410 and 180-390 s, respectively, in platelet rich plasma and 230-460 and 230-545 s in platelet poor plasma. Furthermore, only 8a showed antiplatelet activity by inhibiting epinephrine-induced platelet aggregation, and the observed aggregation inhibition was found to be 93.4%. Compounds 8a-f show nontoxic properties because of the non-hydrolyzing properties in the RBC cells. In addition, 8a and 8d show anti-edema and anti-hemorrhagic properties in the experimental mice. These findings reveal that benzimidazole-containing quinolinyl oxadiazoles act as α-glucosidase inhibitors to develop novel therapeutics for treating type-II diabetes mellitus and can act as lead molecules in drug discovery as potential antidiabetic and antithrombotic agents.

Abstract
In an efficient exploitation of solid-phase chemistry, this work describes the preparation of the new resin-bound 4-( N-arylamino)-3-aminobenzoates and their successful cyclocondensations with the sodium bisulfite adducts of different aldehydes and triethyl orthoformate or triethyl orthoacetate, followed by resin cleavage to produce the target 1,2-diaryl- and 1-aryl-2-(un)substituted benzimidazole-5-carboxylic acid derivatives, respectively. In another variation, the cyclocondensation of the resin-bound 4-( N-arylamino)-3-aminobenzoates with carbon disulfide afforded the corresponding resin-bound thioxobenzimidazoles, which upon cleavage gave the corresponding 2-thioxobenzimidazoles. S-Alkylation of the resin-bound thioxobenzimidazoles with benzyl chloride and 4-bromophenacyl bromide furnished 2-benzylsulfanyl benzimidazoles and 4-bromophenyl-2-oxoethylsulfanyl-benzimidazoles, respectively. Reacting the resin-bound 4-( N-arylamino)-3-aminobenzoates with phenyl isothiocyanate gave the open-form 4-(arylamino)-3-(3-phenylthioureido) benzoic acids. Moreover, the reaction of the resin-bound 4-( N-arylamino)-3-aminobenzoates with N,N-carbonyldiimidazole yielded the corresponding 2-bezimidazolones.

Abstract
Newly synthesized benzimidazole hydrazone derivatives 1-26 were evaluated for their α-glucosidase inhibitory activity. Compounds 1-26 exhibited varying degrees of yeast α-glucosidase inhibitory activity with IC50 values between 8.40 ± 0.76 and 179.71 ± 1.11 μM when compared with standard acarbose. In this assay, seven compounds that showed highest inhibitory effects than the rest of benzimidazole series were identified. All the synthesized compounds were characterized by different spectroscopic methods adequately. We further evaluated the interaction of the active compounds with enzyme with the help of docking studies.

Abstract
Apoptotic cell death is the cause of the loss of insulin-producing β-cells in all forms of diabetes mellitus. The identification of small molecules capable of protecting cytokine-induced apoptosis could form the basis of useful therapeutic interventions. Here in, we present the discovery and synthesis of new benzimidazole derivatives, capable of rescuing pancreatic β-cells from cytokine-induced apoptosis. Three hydrazone derivatives of benzimidazole significantly increased the cellular ATP levels, reduced caspase-3 activity, reduced nitrite production and increased glucose-stimulated insulin secretion in the presence of proinflammatory cytokines. These findings suggest that these compounds may protect β-cells from the harmful effects of cytokines and may serve as candidates for therapeutic intervention for diabetes.

Abstract
In this work, the biological activity of some benzimidazoles and benzimidazole-4,7-diones was compared. These two groups of compounds were evaluated as potential chemotherapeutics and their characteristic relationship structure to biological activity was discussed. The authors compared their effect into the cytotoxic, apoptosis and DNA destruction approach. Their cytotoxic effect on the human lung adenocarcinoma A549 cells line was determined by WST-1 test. Next the cytotoxic way of tumor cells death was determined by caspase 3/7 test. The last point referred to the DNA destruction of A549 cells and test in situ DNA Assay Kit was applied. Two of the examined compounds (B2 and D2) show a very good correlation of the cytotoxic effect normoxia to hypoxia and they have been found as the potential agents of the DNA damage. The most cytotoxic feature possesses N-oxide benzimidazole derivatives (D and B groups). The screening test of the DNA damage established that N-oxide benzimidazole derivatives (D and B groups) can be more potent as the hypoxia-selective agents for tumor cells than benzimidazole derivatives (A and C groups). Additionally, the test of the caspase-dependent apoptosis proved that the exposure of benzimidazole-4,7-diones against A549 cells, especially in hypoxia, promotes apoptotic cell death.

Biological evaluation of the activity of some benzimidazole-4,7-dione derivatives. Molecules 2014; 19:15361-73. [PMID: 25264827 PMCID: PMC6271954 DOI: 10.3390/molecules191015361] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2014] [Revised: 09/09/2014] [Accepted: 09/11/2014] [Indexed: 11/17/2022] Open
Abstract
The study presented here is a follow up of the authors’ interest in the approach to selective and cytotoxic bioreductive anticancer prodrugs. The current work is devoted to explore both the biological activity of some previously obtained compounds and the search for an explanation of their target(s) in hypoxic pathways. In this work the biological activity of some benzimidazole-4,7-diones was evaluated. These compounds were examined as potential bioreductive agents specific for the hypoxic environment found in tumor cells. The main aim was concerned with establishing their cytotoxic properties by using proliferation, apoptosis and DNA destruction tests on selected tumor cells. Their cytotoxic effects on two tumor cell lines (human lung adenocarcinoma A549 cells line and human malignant melanoma WM115) was compared by means of a WST-1 test. Next, the mode of cytotoxicity behind the selected tumor cells’ death was determined by the caspase 3/7 test. The last point referred to the DNA destruction of A549 and WM115 cells and the in situ DNA Assay Kit test was applied. The cytotoxic tests confirmed their activity against the tumor cells and target hypoxia (compounds 2b, 2a, 2d). The screening test of the caspase-dependent apoptosis proved that the exposure of the tested tumor cells in hypoxia to these benzimidazole-4,7-diones promoted the apoptotic cell death. Additionally, the DNA damage test established that benzimidazole-4,7-diones can be potential hypoxia-selective agents for tumor cells, especially compound 2b. All results classify the tested benzimidazole-4,7-diones as promising, lead molecules and provide a rationale for further molecular studies to explain their usefulness as potential inhibitors of the hypoxia-inducible factor 1 (HIF1).

Synthesis, anticancer activity and UPLC analysis of the stability of some new benzimidazole-4,7-dione derivatives. Molecules 2013; 19:400-13. [PMID: 24384922 PMCID: PMC6271476 DOI: 10.3390/molecules19010400] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2013] [Revised: 12/09/2013] [Accepted: 12/16/2013] [Indexed: 12/18/2022] Open
Abstract
In this work, a sensitive analytical method to study the stability of two new series of synthesized heterocyclic compounds, the benzimidazole-4,7-diones 5 and N-oxide benzimidazole-4,7-dione derivatives 6 was established and validated. These derivatives were developed as potential anticancer substances to be activated under hypoxic conditions. At this point we were concerned with establishing their stability in some specific environments for further biological studies. For that, we developed and validated an RP-UPLC method. Next, selected compounds were tested in vitro for possible anticancer activity. Their effect on A549 tumour cell lines under normoxia and hypoxia conditions was determined by a WST-1 test. Four of the examined compounds (compounds 5a–c and 6c) showed very good antiproliferative effects and three of them (compounds 6a, 6b and 6d) were specific for hypoxia conditions. The hypoxia/normoxia cytotoxic coefficient of compound 6b is close to that of tirapazamine—a reference compound in our experiments—and this parameter locates it between mitomycin C and 2-nitroimidazole (misonidazole).

The influence of the aziridinyl substituent of benzimidazoles and benzimidazolequinones on toxicity towards normal and Fanconi anaemia cells. Eur J Med Chem 2010; 45:1873-9.

Abstract
Aziridinyl substituted benzimidazolequinones are more toxic than methoxy analogues towards normal human fibroblast cells (GM00637). The aziridinyl substituent is required for hypersensitive killing of Fanconi anaemia (FA) cells (PD20i) deficient in FANCD2. Despite lacking quinone functionality, 4,7-dimethoxy-N-[(aziridin-2-yl)methyl]benzimidazole also induces hypersensitivity from FA cells, similar to their response towards mitomycin C. Expression of FANCD2 (in PD20:RV) corrects FA cell hypersensitivity supporting cellular response via the FANC pathway.

Abstract
A series of N-(acridin-9-yl)-4-(benzo[d]imidazol/oxazol-2-yl) benzamides has been synthesized by the condensation of 9-aminoacridine derivatives with benzimidazole or benzoxazole derivatives. Condensation of 2-hydroxy naphthaldehyde with functionalized diamines leads to the formation of Schiff's bases and not imidazole derivatives. All these compounds were characterized by correct FT-IR, (1)H NMR, MS and elemental analyses. These compounds were screened for anti-inflammatory, analgesic and kinase (CDK-1, CDK-5 and GSK-3) inhibition activities. Compounds 11 and 7e(f) showed good anti-inflammatory (35.8% at 50 mg/kg po) activity and good analgesic activity (60% at 50 mg/kg po), respectively. Compound 3b showed significant in vitro activity against CDK-5 (IC(50)=4.6 microM) and CDK-1(IC(50)=7.4 microM) and compound 3a showed moderate CDK-5 inhibitory activity (IC(50)=7.5 microM). The other compounds showed moderate anti-inflammatory and analgesic activities.

Abstract
A focused set of heterocyclic quinones based on the benzothiazole, benzoxazole, benzimidazole, indazole and isoindole was prepared and screened with respect to the inhibition of the phosphatase activity of CDC25C. Benzoxazole- and benzothiazole-diones were at least 50 times more potent in inhibiting CDC25C than their benzimidazole-indazole- or isoindole-dione counterparts. These in vitro activities were in good correlation with the anti-proliferative effects observed with Mia PaCa-2 and DU-145 human tumor cell cultures. The IC(50) values obtained by WST-1 colorimetric assay ranged from 0.10 to 0.50 microM for the benzoxazole- or benzothiazole-diones and were above 10 microM for the other heterocyclic diones. This study further illustrates how the activity of the quinone pharmacophore can be selectively modulated by changing the type of five-membered heterocycle fused to the quinone ring.
