In Silico Screening and Analysis of Broad-Spectrum Molecular Targets and Lead Compounds for Diarrhea Therapy

Diarrhoeal disease kills about 1.5 million human beings per year across the continents. The enterotoxigenic Escherichia coli (ETEC) pathotype has been noted as a major cause of diarrheal disease in human and livestock. The aim of this study is to identify broad-spectrum molecular targets in bacteria and broad-spectrum lead compounds (functional inhibitors) with high efficacy and no significant adverse implication on human systems, in relevance to diarrhea therapy through computational approaches which include phylogenetics, target prediction, molecular docking, and molecular flexibility dynamic simulations. Three molecular target genes, murA, dxr, and DnaE, which code for uridine diphosphate-N-acetylglucosamine-1-carboxyvinyltransferase, 1-deoxy-D-xylulose-5-phosphate reductoisomerase, and deoxyribonucleic acid polymerase III alpha subunit, respectively, were found to be highly conserved in 7 diarrhea-causing microbes. In addition, 21 potential compounds identified showed varied degree of affinity to these enzymes. At free energy cutoff of ?8.0 kcal/mol, the highest effective molecular target was DNA polymerase III alpha subunit (PDB ID: 4JOM) followed by UDP-N-acetylglucosamine-1-carboxyvinyltransferase (PDB ID: 5UJS), and 1-deoxy-D-xylulose-5-phosphate reductoisomerase (PDB ID: 1ONN), while the highest effective lead compound was N-coeleneterazine followed by amphotericin B, MMV010576, MMV687800, MMV028694, azithromycin, and diphenoxylate. The flexibility dynamics of DNA polymerase III alpha subunit unraveled the atomic fluctuation which potentially implicated Asp593 as unstable active site amino acid residue. In conclusion, bacteria DnaE gene or its protein is a highly promising molecular target for the next generation of antibacterial drugs of the class of N-coeleneterazine.

Carbazole scaffold in medicinal chemistry and natural products: A review from 2010-2015

9H-carbazole is an aromatic molecule that is tricyclic in nature, with two benzene rings fused onto a 5-membered pyrrole ring. Obtained from natural sources or by synthetic routes, this scaffold has gained much interest due to its wide range of biological activity upon modifications, including antibacterial, antimalarial, anticancer, and anti-Alzheimer properties. This review reports a survey of the literature on carbazole-containing molecules and their medicinal activities from 2010 through 2015. In particular, we focus on their in vitro and in vivo activities and summarize structure-activity relationships (SAR), mechanisms of action, and/or cytotoxicity/selectivity findings when available to provide future guidance for the development of clinically useful agents from this template.

Aim: VEGFR2 tyrosine kinase is a main target in suppressing cancer growth and metastasis. Materials & methods: Piperazine-based thiazolidinones were synthesized and screened for their anticancer and VEGFR2 tyrosine kinase inhibitory activity. Results: Compounds 11, 13 and 16 displayed potent anticancer activity against HepG-2 with IC50 values 0.03-0.06 muM. They were safe on normal human fibroblasts with selectivity indices 8.09, 11.40 and 4.37, respectively. Also, these compounds showed VEGFR2 tyrosine kinase inhibitory activities more than the reference staurosporine with IC50 values <0.3 muM. Lineweaver-Burk plot revealed that these compounds behaved as uncompetitive VEGFR2 tyrosine kinase inhibitors. They also induced caspase-dependent apoptosis in HepG-2. In addition, these compounds revealed good binding within VEGFR2 tyrosine kinase enzyme in comparison with sorafenib reference. Conclusion: Compounds 11, 13 and 16 comprise a new promising scaffold of selective VEGFR2 tyrosine kinase inhibitors with caspase-dependent apoptotic activities. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. name: Thiazolidin-2-one, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 2682-49-7, in my other articles.

Spectroscopic investigations of the interactions of potential antitumor amino-thiazolidinone platinum (II) compounds with human serum albumin

An amino-thiazolidinone platinum(II) compound which could rapidly induce apoptosis in tumor cells and showed no cross resistance against the cisplatin-resistant cells, was firstly to study of protein-drug interactions. To investigate the potential of Pt(II) compounds as therapeutic drugs, two Pt(II) complexes (1 and 2) were explored the influences based on their interaction in vitro with human serum albumin (HSA) by fluorescence spectrometry and UV?Vis absorption. The binding interactions of two compounds with HSA results in the formation of corresponding HSA-drug complexes, van der Waals forces and hydrogen bonding played key roles in stabilizing these complexes. Both of two compounds were through a dynamic quenching mechanism, this dynamic reversible binding process was of great significance to the equilibrium of drug concentrations in vivo, which ensured that the internal environment of the organism was in a relatively stable state.

Current status and future prospects of Marine Natural Products (MNPs) as antimicrobials

The marine environment is a rich source of chemically diverse, biologically active natural products, and serves as an invaluable resource in the ongoing search for novel antimicrobial compounds. Recent advances in extraction and isolation techniques, and in state-of-the-art technologies involved in organic synthesis and chemical structure elucidation, have accelerated the numbers of antimicrobial molecules originating from the ocean moving into clinical trials. The chemical diversity associated with these marine-derived molecules is immense, varying from simple linear peptides and fatty acids to complex alkaloids, terpenes and polyketides, etc. Such an array of structurally distinct molecules performs functionally diverse biological activities against many pathogenic bacteria and fungi, making marine-derived natural products valuable commodities, particularly in the current age of antimicrobial resistance. In this review, we have highlighted several marine-derived natural products (and their synthetic derivatives), which have gained recognition as effective antimicrobial agents over the past five years (2012?2017). These natural products have been categorized based on their chemical structures and the structure-activity mediated relationships of some of these bioactive molecules have been discussed. Finally, we have provided an insight into how genome mining efforts are likely to expedite the discovery of novel antimicrobial compounds.

Biased signaling and allosteric modulation at the FSHR

Knowledge on G protein-coupled receptor (GPCRs) structure and mechanism of activation has profoundly evolved over the past years. The way drugs targeting this family of receptors are discovered and used has also changed. Ligands appear to bind a growing number of GPCRs in a competitive or allosteric manner to elicit balanced signaling or biased signaling (i.e., differential efficacy in activating or inhibiting selective signaling pathway(s) compared to the reference ligand). These novel concepts and developments transform our understanding of the follicle-stimulating hormone (FSH) receptor (FSHR) biology and the way it could be pharmacologically modulated in the future. The FSHR is expressed in somatic cells of the gonads and plays a major role in reproduction. When compared to classical GPCRs, the FSHR exhibits intrinsic peculiarities, such as a very large NH2-terminal extracellular domain that binds a naturally heterogeneous, large heterodimeric glycoprotein, namely FSH. Once activated, the FSHR couples to Galphas and, in some instances, to other Galpha subunits. G protein-coupled receptor kinases and beta-arrestins are also recruited to this receptor and account for its desensitization, trafficking, and intracellular signaling. Different classes of pharmacological tools capable of biasing FSHR signaling have been reported and open promising prospects both in basic research and for therapeutic applications. Here we provide an updated review of the most salient peculiarities of FSHR signaling and its selective modulation.

Structural features and inhibitors of bromodomains

Bromodomains are conserved structural modules responsible for recognizing acetylated-lysine residues on histone tails and other transcription-associated proteins, such as transcription factors and co-factors. Owing to their important functions in the regulation of ordered gene transcription in chromatin, bromodomains of the BET family proteins have recently been shown as druggable targets for a wide array of human diseases, including cancer and inflammation. Here we review the structural and functional features of the bromodomains and their small-molecule inhibitors. Additional new insights provided herein highlight the landscape of the ligand binding sites in the bromodomains that will hopefully facilitate further development of new inhibitors with optimal affinity and selectivity.

Synthesis of novel phenyl substituted dibenzonaphthyridines

The reaction of 2,4-dichloroquinolines with 2-amino-5-chlorobenzophenone yielded 2-[(2-benzoyl-4-chlorophenyl) amino]-4-chloroquinolines which with sodium methoxide afforded 2-[(2-benzoyl-4-chlorophenyl)amino]-4- methoxyquinolines. These on PPA-catalysed cyclisation gave 2-chloro-12- phenyldibenzo[b,g][1,8]naphthyridin-11(6H)-ones. Temperature differences for the formation of the final products were due to the in situ formation of the 2-[(2-benzoyl-4-chlorophenyl)amino]quinolin-4-ones from the chloro and methoxy intermediates. The dibenzonaphthyridin-11-ones were N-methylated at N(6); a methyl group at C(7) was found to hinder the methylation reaction sterically, when a considerably longer reaction time was needed.
