The occurrence of resistant mutants of fungi is also observed. Another problem with some known antifungal drugs is that only topical applications are used due to their toxicity or limited bioavailability [1]. Thus this situation justifies the urgency to design and discover not only antibacterial but also antifungal new drugs [2].\u0000Styrylquinoline derivatives structurally related to dichloroquinoline (e.g. chloroxine) are potential antimicrobial compounds. These derivatives were studied by Cieslik et al. [3] recently. Some of these structures expressed antifungal activity comparable with or higher than the standard fluconazole. The antibacterial effect especially against Staphylococcus strains was observed as well [3]. Based on these results, new structures were synthesized and evaluated with respect to their activity, what is presented in this work. New compounds were tested against Candida strains for their antifungal effect and against Staphylococcus and Enteroccocus strains for their antibacterial activity. Antibacterial effects were tested also against methicillin-resistant staphylococci and vancomycin-resistant enterococci.\u0000This contribution was supported by grant FaF UK/9/2018 of the Faculty of Pharmacy of the Comenius University, grant No. UK/229/2018 of the Comenius University, NCN grant Opus:DEC-2013/09/B/NZ7/00423 of the Polish National Centre for Science and partially by SANOFI-AVENTIS Pharma Slovakia, s.r.o.\u0000\u0000Jampilek, J.

Present study was designed to investigate the protective effect of extracts of Cuscuta reflexa Roxb. against adjuvant induced arthritis. Materials and methods: Arthritis was induced by Complete Freund’s adjuvant. Arthritic rats were treated with methanol and aqueous extract of Cuscuta reflexa Roxb. Diclofenac sodium was used as standard treatment. Protection against arthritis was investigated using various parameters like paw thickness, changes in whole body weight, weight of spleen and thymus, pain in inflammation by using thermal stimulus, radiological and histological analysis of the joint and serum levels of biochemical markers and inflammatory mediators (TNF-α and IL-6). Methanol extract of Cuscuta reflexa Roxb. (MECR) was fractionalized and its fraction was subjected to IR and LC/MS analysis. Results: Treatment of arthritic rats with methanol and aqueous extracts of Cuscuta reflexa Roxb. significantly protected the animals from the arthritic changes as compared to the arthritic control group. Elevated levels of inflammatory cytokines, lipid peroxidation and other biochemical and pathological changes associated with arthritis were normalized by the treatment of MECR and AECR. Results suggest significant antiinflammatory and antiarthritic effects.","PeriodicalId":20450,"journal":{"name":"Proceedings of 4th International Electronic Conference on Medicinal Chemistry","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87305362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Azadirachta indica (Local name: Neem, Family: Meliaceae) is a medicinal plant best known for its antimicrobial, antiinflammatory, anticancer and antiviral activities. It is a fact that the individual exudates of each plant attract a specific species of microbes and induce them to produce possible novel compounds under the influence of the plant environment. With this idea in mind, we investigated the antimicrobial activity of endophytic actinomycetes inhabiting tulsi and neem plants. The preliminary screening was done using agar plug method and it displayed 12 isolates with prominent bioactivity. Further biological screening of their active metabolites showed that the compounds were most active against Salmonella enteritidis, Campylobacter jejuni and Proteus mirabilis. The thin layer chromatography (TLC) and high performance liquid chromatography-UV (HPLC-UV) displayed UV absorbing polar and non polar compounds.

L. formosana is a famous ornamental plant for leaves are green in spring and summer, and red in autumn. Different plant parts of L. formosana, such as leaf, fruit, bark, and resin, are proved to be treasures as natural medicinal plant resources [1]. Among the bioactive constituents, several diterpenoid acids of the abietane family have been identified. Abietic acid (1) occurs in plants of the genus Abies and is the first member of a class of plant metabolites, the abietane-type diterpenoids. They are characterized by a tricyclic ring system and have shown a wide range of chemical diversity and biological activity.[2,3] Medicinal chemists have studied derivatives of two readily available materials such as dehydroabietic acid (2) and dehydroabietylamine (3, DHAA).[3] To date, there is only one commercial drug, Ecabet® [ecabet sodium (4)], based on abietanes, which is used for the treatment of reflux esophagitis and peptic ulcer disease. Ferruginol (5) exhibits anticancer effects in human ovarian cancer and inhibition of cancer cell migration. Recent studies of sugiol (6) demonstrated in vivo antitumor activity in DU145 prostate xenografts. These biological reports and the simultaneous isolation, (in 2014) by Hua and co-workers, of the new abietane liquiditerpenoic acid A (7), a sugiol analogue, from the resin of Liquidambar formosana [4] and from Pinus massoniana,[5] by Kuo and co-workers named independently as abietopinoic acid, prompted us to synthesize it and study its biological properties along with some analogues.\u0000References \u0000[1] Ouyang, X.

Special prediction is a tool for the prediction of antimicrobial potency of peptides against particular target species with high accuracy. This tool is included into the Database of Antimicrobial Activity and Structure of Peptides (DBAASP, https://dbaasp.org [3]). In this presentation we describe this tool and predictive models for some Gram positive bacterial strains (Staphylococcus aureus ATCC 25923 and Bacillus subtilis) and a model for the prediction of hemolytic activity. Predictive model for Gram negative Escherichia coli ATCC 25922 was presented earlier [2,4]. Special prediction tool can be used for the design of peptides being active against particular strain. To demonstrate the capability of the tool, peptides predicted as active against E-coli ATCC 25922 and Staphylococcus aureus ATCC 25923 have been synthesized, and tested in vitro.

In fact, it has been demonstrated that isoprenylation of flavonoids significantly increased their growth inhibitory effect on human tumor cell lines [2]. A series of prenylchalcones was synthesized and evaluated for the ability to inhibit the MDM2-p53 interaction using a yeast-based assay [3]. The capacity of all synthesized prenylchalcones and their non-prenylated precursors to inhibit the growth of human colon tumor HCT116 cells was evaluated and compared [3]. The overall results led to the identification of a hit compound, which behaved as potential inhibitor of the MDM2-p53 interaction in yeast, and showed improved cytotoxicity against human tumor cells expressing wild-type p53. In HCT116 cancer cells, it was also shown that the growth inhibitory effect of this prenylchalcone was associated with the induction of cell cycle arrest, and apoptosis. S. Venturelli et al.

{"title":"Unusual binding modes of two inhibitors to their target enzymes human leukocyte elastase (HLE) and protein kinase CK2 revealed by protein crystallography","authors":"J. Hochscherf, K. Niefind","doi":"10.3390/ECMC-4-05572","DOIUrl":"https://doi.org/10.3390/ECMC-4-05572","url":null,"abstract":"The main subjects of this keynote are protein kinase CK2 and human leukocyte elastase (HLE), two biomedically important enzymes and pharmacologically attractive targets.\u0000CK2 - more precisely its catalytic subunit CK2alpha - is a member of the superfamily of eukaryotic protein kinases. Its antiapoptotic activity is exploited by tumour cells in order to escape cell death. The indeno[1,2-b]indole scaffold, a flat annulated 4-ring system, is a relatively novel lead structure for the development of ATP-competitive CK2 inhibitors. Complex structures of CK2alpha and a number of indeno[1,2-b]indole-type compounds had been predicted previously. In such an in silico model the inhibitor sticks in the ATP cavity in an apparently plausible way, namely such that its hydrophobic side is directed inwards while its hydrophilic side has access to the solvent. However, when we determined the first co-crystal of CK2alpha with an indeno[1,2-b]indole-type inhibitor, we realized to our surprise that the orientation of the inhibitor was reversed: the \"hydrophobic-out/oxygen-out\" binding mode that we discovered is determined by hydrogen bonds of the inhibitor to a hidden and conserved water molecule. This molecular arrangement requires an inhibitor orientation in which hydrophobic substitutents are at the outer surface which opens the possibility for further modifications.\u0000The second target enzyme, human leukocyte elastase (HLE), is a chymotrypsin-type serine protease which is produced by neutrophilic granulocytes, the most abundant cells of the innate immune system [therefore the synonym \"human neutrophil elastase\" (HNE)]. The activity of HLE must be strictly controlled to avoid proteolytic damage of the connective tissue which is a particular problem in chronic obstructive pulmonary disease (COPD) and other inflammatory diseases. Naturally, HLE is downregulated by alpha1-antitrypsin, a serpin-type protease inhibitor, which is likewise produced by neutrophils. Synthetic HLE inhibitors are useful in cases of inbalance of the natural HLE control system. Typically, HLE inhibibitors block the S1 pocket of the enzyme, the most critical of several substrate binding cavities. The S1 pocket recognizes the side chain of the substrate directly N-terminal of the peptide bond to be hydrolyzed. In our study we co-crystallized HLE with a 1,3-thiazolidine-2,4-dione derivative with antibacterial activity that had been observed to inhibit HLE as well. In the complex structure the inhibitor is bound to the S2' site, i.e. at a region responsible for harbouring residues at the C-terminal side of the scissile peptide bond. In addition, the inhibitor seems to induce a dimerization of the enzyme by which the access to the active site region is prohibited.","PeriodicalId":20450,"journal":{"name":"Proceedings of 4th International Electronic Conference on Medicinal Chemistry","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78349290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
