Antifungal and anti-inflammatory potential of eschweilenol C-rich fraction derived from Terminalia fagifolia Mart.[Pubmed:31100435]
J Ethnopharmacol. 2019 Aug 10;240:111941.
ETHNOPHARMACOLOGICAL RELEVANCE: Folk knowledge transmitted between generations allows traditional populations to maintain the use of medicinal plants for the treatment of several diseases. In this context, the species Terminalia fagifolia Mart., native to Brazil, is used for the treatment of chronic and infectious diseases. Plants rich in secondary metabolites, such as this species and their derivatives, may represent therapeutic alternatives for the treatment of diseases that reduce the quality of life of people. AIM OF THE STUDY: The aim of this study was to evaluate the antifungal and anti-inflammatory potential of aqueous fraction from ethanolic extract of T. fagifolia, with in silico study of the major compound of the fraction. MATERIAL AND METHODS: The phytochemical study of the aqueous fraction was performed by HPLC, LC/MS and NMR. The antifungal activity was evaluated against yeasts, by determination of the minimum inhibitory concentration and minimum fungicidal concentration. The effect on Candida albicans was analyzed by AFM. The antibiofilm potential against biofilms of C. albicans was also tested. The anti-inflammatory potential of the aqueous fraction was evaluated in vivo by the carrageenan-induced paw edema and peritonitis. A microglial model of LPS-induced neuroinflammation was also studied. Further insights on the activation mechanism were studied using quantum chemistry computer simulations. Toxicity was evaluated in the Galleria mellonella and human erythrocytes models. RESULTS: Eschweilenol C was identified as the major constituent of the aqueous fraction of the ethanolic extract of T. fagifolia. The aqueous fraction was active against all Candida strains used (sensitive and resistant to Fluconazole) with MICs ranging from 1000 to 0.4mug/mL. By AFM it was possible to observe morphological alterations in treated Candida cells. The fraction significantly (p<0.05) inhibited paw edema and decreased levels of malondialdehyde induced by carrageenan. In a microglial cell model, aqueous fraction demonstrated the ability to inhibit NF-kappaB after induction with lipopolysaccharide. The theoretical studies showed structural similarity between Eschweilenol C and indomethacin and an excellent antioxidant potential. The aqueous fraction did not present toxicity in the studied models. CONCLUSION: The results indicate that the aqueous fraction of T. fagifolia has potential for biomedical applications with low toxicity. This finding can be attributed to the predominance of Eschweilenol C in the aqueous fraction.
N-myristoyltransferases inhibitory activity of ellagitannins from Terminalia bentzoe (L.) L. f. subsp. bentzoe.[Pubmed:30342177]
Fitoterapia. 2018 Nov;131:91-95.
N-myristoylation (Myr) is an eukaryotic N-terminal co- or post-translational protein modification in which the enzyme N-myristoyltransferase (NMT) transfers a fatty acid (C14:0) to the N-terminal glycine residues of several cellular key proteins. Depending on the cellular context, NMT may serve as a molecular target in anticancer or anti-infectious therapy, and drugs that inhibit this enzyme may be useful in the treatment of cancer or infectious diseases. As part of an on-going project to identify natural Homo sapiens N-myristoyltransferase 1 inhibitors (HsNMT1), two ellagitannins, punicalagin (1) and isoterchebulin (2), along with Eschweilenol C (3) and ellagic acid (4) were isolated from the bark of Terminalia bentzoe (L.) L. f. subsp. bentzoe. Their structures were determined by means of spectroscopic analyses and comparison with literature data. Punicalagin (1) and isoterchebulin (2) showed significant inhibitory activity towards HsNMT1, and also against Plasmodium falciparum NMT (PfNMT) both in vitro and in cellulo, opening alternative paths for new NMT inhibitors development. This is the first report identifying natural products from a botanical source as inhibitors of HsNMT and PfNMT.
Three new ellagic acid derivatives from the bark of Eschweilera coriacea from the Suriname rainforest.[Pubmed:9677272]
J Nat Prod. 1998 Jul;61(7):901-6.
Bioassay-guided fractionation of Eschweilera coriacea collected in the lowland wet forest of Suriname yielded the new but only weakly active ellagic acid derivative eschweilenol A (1) and the two new but inactive ellagic acid derivatives eschweilenol B (2) and Eschweilenol C (3). The four known compounds, sucrose, ellagic acid, 3-O-galloylepigallocatechin, and epigallocatechin, were also isolated. The structures of the three new compounds were determined by spectrometric methods, primarily from the HMQC, HMBC, NOESY, and ROESY NMR techniques, and chemical methods, including methylation and triethylsilylation. The location of a hydroxyl group in one ellagic acid derivative was determined by a new technique involving an NOE correlation of the protons of a triethylsilyl derivative with a proton on a neighboring aromatic ring.
