Novel benzimidazole phosphonates as potential inhibitors of protein prenylation.

ABSTRACT: Benzimidazole carboxyphosphonates and bisphosphonates have been prepared and evaluated for their activity as inhibitors of protein prenylation or isoprenoid biosynthesis. The nature of the phosphonate head group was found to dictate enzyme specificity. The lead carboxyphosphonate inhibits geranylgeranyl transferase II while its corresponding bisphosphonate analogue potently inhibits farnesyl diphosphate synthase. The most active inhibitors effectively disrupted protein prenylation in human multiple myeloma cells.

Substituted Benzimidazole Analogues as Potential α-Amylase Inhibitors and Radical Scavengers.

Project description:Benzimidazole scaffolds are known to have a diverse range of biological activities and found to be antidiabetic and antioxidant. In this study, a variety of arylated benzimidazoles 1-31 were synthesized. Except for compounds 1, 6, 7, and 8, all are new derivatives. All compounds were screened for α-amylase inhibitory, 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), and 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activities. In vitro screening results revealed that all molecules demonstrated significant α-amylase inhibition with IC50 values of 1.86 ± 0.08 to 3.16 ± 0.31 μM as compared to standard acarbose (IC50 = 1.46 ± 0.26 μM). However, compounds showed significant ABTS and DPPH radical scavenging potentials with IC50 values in the range of 1.37 ± 0.21 to 4.00 ± 0.10 μM for ABTS and 1.36 ± 0.09 to 3.60 ± 0.20 μM for DPPH radical scavenging activities when compared to ascorbic acid with IC50 values of 0.72 ± 0.21 and 0.73 ± 0.05 μM for ABTS and DPPH radical scavenging potentials, respectively. Structure-activity relationship (SAR) was established after critical analysis of varying substitution effects on α-amylase inhibitory and radical scavenging (ABTS and DPPH) potentials. However, molecular docking was also performed to figure out the active participation of different groups of synthetic molecules during binding with the active pocket of the α-amylase enzyme.

Structure-Based Design of Novel Benzimidazole Derivatives as Pin1 Inhibitors.

Project description:Peptidyl-prolyl cis/trans isomerase Pin1 plays a key role in amplifying and translating multiple oncogenic signaling pathways during oncogenesis. The blockade of Pin1 provided a unique way of disrupting multiple oncogenic pathways and inducing apoptosis. Aiming to develop potent Pin1 inhibitors, a series of benzimidazole derivatives were designed and synthesized. Among the derivatives, compounds 6h and 13g showed the most potent Pin1 inhibitory activity with IC50 values of 0.64 and 0.37 μM, respectively. In vitro antiproliferative assay demonstrated that compounds 6d, 6g, 6h, 6n, 6o and 7c exhibited moderate antiproliferative activity against human prostate cancer PC-3 cells. Taken together, these unique benzimidazole derivatives exhibited great potential to be further explored as potent Pin1 inhibitors with improved potency.

Fighting Antibiotic Resistance: New Pyrimidine-Clubbed Benzimidazole Derivatives as Potential DHFR Inhibitors.

Project description:The present work describes the design and development of seventeen pyrimidine-clubbed benzimidazole derivatives as potential dihydrofolate reductase (DHFR) inhibitors. These compounds were filtered by using ADMET, drug-likeness characteristics calculations, and molecular docking experiments. Compounds 27, 29, 30, 33, 37, 38, and 41 were chosen for the synthesis based on the results of the in silico screening. Each of the synthesized compounds was tested for its in vitro antibacterial and antifungal activities using a variety of strains. All the compounds showed antibacterial properties against Gram-positive bacteria (Staphylococcus aureus and Staphylococcus pyogenes) as well as Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa). Most of the compounds either had a higher potency than chloramphenicol or an equivalent potency to ciprofloxacin. Compounds 29 and 33 were effective against all the bacterial and fungal strains. Finally, the 1,2,3,4-tetrahydropyrimidine-2-thiol derivatives with a 6-chloro-2-(chloromethyl)-1H-benzo[d]imidazole moiety are potent enough to be considered a promising lead for the discovery of an effective antibacterial agent.

Synthesis and Antifungal Potential of Some Novel Benzimidazole-1,3,4-Oxadiazole Compounds.

Project description:Discovery of novel anticandidal agents with clarified mechanisms of action, could be a rationalist approach against diverse pathogenic fungal strains due to the rise of resistance to existing drugs. In support to this hypothesis, in this paper, a series of benzimidazole-oxadiazole compounds were synthesized and subjected to antifungal activity evaluation. In vitro activity assays indicated that some of the compounds exhibited moderate to potent antifungal activities against tested Candida species when compared positive control amphotericin B and ketoconazole. The most active compounds 4h and 4p were evaluated in terms of inhibitory activity upon ergosterol biosynthesis by an LC-MS-MS method and it was determined that they inhibited ergosterol synthesis concentration dependently. Docking studies examining interactions between most active compounds and lanosterol 14-α-demethylase also supported the in vitro results.

Combinatorial modulation of protein prenylation.

Project description:The cell has >60 different farnesylated proteins. Many critically important signal transduction proteins are post-translationally modified with attachment of a farnesyl isoprenoid catalyzed by protein farnesyltransferase (FTase). Recently, it has been shown that farnesyl diphosphate (FPP) analogues can alter the peptide substrate specificity of FTase. We have used combinatorial screening of FPP analogues and peptide substrates to identify patterns in FTase substrate selectivity. Each FPP analogue displays a unique pattern of substrate reactivity with the tested peptides; FTase efficiently catalyzes the transfer of an FPP analogue selectively to one peptide and not another. Furthermore, we have demonstrated that these analogues can enter cells and be incorporated into proteins. These FPP analogues could serve as selective tools to examine the role prenylation plays in individual protein function.

Pharmacological and Toxicological Screening of Novel Benzimidazole-Morpholine Derivatives as Dual-Acting Inhibitors.

Project description:The aim of this study was to investigate acetylcholinesterase (AChE), monoamine oxidase A (MAO-A), monoamine oxidase B (MAO-B), cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzyme inhibitory, and antimicrobial activities of a new series of 2-(4-substituted phenyl)-1-[2-(morpholin-4-yl)ethyl]-1H-benzimidazole derivatives, for their possible use as multi-action therapeutic agents. Target compounds (n = 15) were synthesized under microwave irradiation conditions in two steps, and their structures were elucidated by FT-IR, ¹H-NMR, 13C-NMR and high resolution mass spectroscopic analyses. Pharmacological screening studies revealed that two of the compounds (2b and 2j) have inhibitory potential on both COX-1 and COX-2 enzymes. In addition, cytotoxic and genotoxic properties of the compounds 2b, 2j and 2m were investigated via the well-known MTT and Ames tests, which revealed that the mentioned compounds are non-cytotoxic and non-genotoxic. As a concise conclusion, two novel compounds were characterized as potential candidates for treatment of frequently encountered inflammatory diseases.

Benzimidazole-Based FabI Inhibitors: A Promising Novel Scaffold for Anti-staphylococcal Drug Development.

Project description:The enoyl-ACP reductase (FabI) enzyme is a well validated target for anti-staphylococcal drug discovery and development. With the goal of finding alternate therapeutics for drug-resistant strains of Staphylococcus aureus, such as methicillin-resistant S. aureus (MRSA), our previously published series of benzimidazole-based inhibitors of the FabI enzyme from Francisella tularensis (FtFabI) have been evaluated against FabI from S. aureus (SaFabI). We report here the preliminary structure-activity relationship of this series and the prioritization of compounds toward lead optimization. Mutational studies have identified key residues that contribute toward stabilizing the inhibitors in the active site of FabI. Mutations that do not significantly impact enzyme function but destabilize inhibitor binding are more likely to occur in nature as organisms evolve to evade the action of antibiotics leading to resistance. Identifying these residues provides guidance for minimizing susceptibility to resistance. Additionally, we have identified compounds that elicit antibacterial activity through off-target effects and observe that close analogs can display differing modes of action (on-target vs off-target) and need to be individually evaluated early on to prioritize compounds for lead optimization. Overall, our data suggest that the benzimidazole scaffold is a promising scaffold for anti-staphylococcal drug development.

Benzimidazole inhibitors of protein kinase CK2 potently inhibit the activity of atypical protein kinase Rio1.

Project description:Benzimidazole derivatives of 5,6-dichlorobenzimidazole 1-?-D-ribofuranoside (DRB) comprise the important class of protein kinase CK2 inhibitors. Depending on the structure, benzimidazoles inhibit CK2 with different selectivity and potency. Besides CK2, the compounds can inhibit, with similar activity, other classical eukaryotic protein kinases (e.g. PIM, DYRK, and PKD). The present results show that a majority of the most common CK2 inhibitors can affect the atypical kinase Rio1 in a nanomolar range. Kinetic data confirmed the mode of action of benzimidazoles as typical ATP-competitive inhibitors. In contrast to toyocamycin-the first discovered small-molecule inhibitor of Rio1-the most potent representative of benzimidazoles TIBI (IC50 = 0.09 µM, K i = 0.05 µM) does not influence the oligomeric state of the Rio1 kinase. Docking studies revealed that TIBI can occupy the ATP-binding site of Rio1 in a manner similar to toyocamycin, and enhances the thermostability of the enzyme.

Heteroaryl Phosphonates as Noncovalent Inhibitors of Both Serine- and Metallocarbapenemases.

Project description:Gram-negative pathogens expressing serine β-lactamases (SBLs) and metallo-β-lactamases (MBLs), especially those with carbapenemase activity, threaten the clinical utility of almost all β-lactam antibiotics. Here we describe the discovery of a heteroaryl phosphonate scaffold that exhibits noncovalent cross-class inhibition of representative carbapenemases, specifically the SBL KPC-2 and the MBLs NDM-1 and VIM-2. The most potent lead, compound 16, exhibited low nM to low μM inhibition of KPC-2, NDM-1, and VIM-2. Compound 16 potentiated imipenem efficacy against resistant clinical and laboratory bacterial strains expressing carbapenemases while showing some cytotoxicity toward human HEK293T cells only at concentrations above 100 μg/mL. Complex structures with KPC-2, NDM-1, and VIM-2 demonstrate how these inhibitors achieve high binding affinity to both enzyme classes. These findings provide a structurally and mechanistically new scaffold for drug discovery targeting multidrug resistant Gram-negative pathogens and more generally highlight the active site features of carbapenemases that can be leveraged for lead discovery.

Targeting protein prenylation for cancer therapy.

Project description:Protein farnesylation and geranylgeranylation, together referred to as prenylation, are lipid post-translational modifications that are required for the transforming activity of many oncogenic proteins, including some RAS family members. This observation prompted the development of inhibitors of farnesyltransferase (FT) and geranylgeranyl-transferase 1 (GGT1) as potential anticancer drugs. In this Review, we discuss the mechanisms by which FT and GGT1 inhibitors (FTIs and GGTIs, respectively) affect signal transduction pathways, cell cycle progression, proliferation and cell survival. In contrast to their preclinical efficacy, only a small subset of patients responds to FTIs. Identifying tumours that depend on farnesylation for survival remains a challenge, and strategies to overcome this are discussed. One GGTI has recently entered the clinic, and the safety and efficacy of GGTIs await results from clinical trials.
