The protein MTA1 with histone deacetylase activity is a member of the nucleosome remodeling complex encoded by the mta1 gene is frequently overexpressed in biologically aggressive epithelial neoplasms. MTA1 is a nuclear co-regulatory molecule that is highly expressed in many cancers and correlates with tumor metastasis and progression. MTA1 alters signaling events in the tumor micro-environment. MTA1 contributes to cancer progression, may serve as a biomarker and therapeutic target for cancer. The main objective of this study is to perform in–silico docking studies and energy minimizations for active sites of mutated MTA1 protein by selecting different naturally available antioxidant molecules in foods to facilitate ligand-binding site interactions and identify the best from the selected...

Staphylococcus aureus is a frequent colonizer of the human body as well as a serious human pathogen. It can cope with stress factors and acquire resistance to antibiotics, thus rendering treatment difficult. Discovering new treatments for this disease is urgently required, especially in view of the emergence of multiple drug resistant organisms and to reduce the total duration of current treatments. Exfoliative toxin A (ETA), produced by Staphylococcus aureus causes scalded skin syndrome which is characterized by the separation of layers of skin. It affects newborns and adults primarily. Hence, therapies for Staphylococcal scalded skin syndrome (SSSS) are critically needed. Seeking a more effective compound for the treatment has been one of the great interests. In the present study, compounds from different plant extracts are permissible to interact with ETA using Schrodinger. The best effective compound gymnemic triacetate was selected from the list of different compounds based on its docking score and binding energy. The result showed that the herbal compound gymnemic triacetate possesses anti-bacterial activity by blocking exfoliative...

Lannea coromandelica (Houtt.) Merr. which is known as Kayu Jawa in Bugis community, Indonesia has been widely used empirically for the treatment of wounds. Ethanol extract from its stem bark is known to have antibacterial, anti-inflammation, and antioxidant activity. The purpose of this study were to isolate, characterize, and determine the antioxidant and antimicrobial activity of the endophytic fungi from the roots of this plant. In this paper, we reported antioxidant and antimicrobial activity of the isolated endophytic fungi from Lannea coromandelica (Houtt.) Merr. and the isolation of the bioactive compound known as citrinin. The structure of citrinin was determined by extensive analysis of the spectroscopic data (1H-NMR, 13C-NMR, 2D NMR, and LC-MS) and comparison to those of the previous report. The antioxidant activity showed that the isolated compound has moderate activity with AAI value of 0.671 and IC50 145.9 ppm while the antimicrobial activity demonstrated that the isolated compound was not active against Escherichia coli ATCC 25922, Salmonella typhi ATCC 14028, Staphylococcus aureus ATCC 25923, and Pseudomonas aeruginosa...

Objective: To investigate the bioactive constituents of Ulva lactuca, Sargassum prismaticum, and Sarconema filiforme using gas chromatography-mass spectrometry (GC-MS) analysis. Methods: 10 gm sample of each seaweed was successfully extracted with HPLC grade methanol and pet. ether with continuous shaking in a dark room for 36 h. The concentrated extracts were subjected to GC MS analysis. Results: The GC MS analysis of methanol and pet ether extracts of U. lactuca, S. prismaticum and S. filiforme show various types of phytocompounds screened under different R.T. Major compounds were 9-Octadecenoic acid (Z)-, phenyl-methyl ester, Stannane,1,3-dithian-2-ylidenebis[tributyl,Octadecane, 3-ethyl-5-(2-ethylbutyl) in methanol extract and Decane, 6-ethyl-2-methyl-, Tricosane and Sulfurous acid, 2-ethylhexyl hexyl ester in pet. ether. These bioactive compounds are considered as biologically and pharmacologically important. Conclusion: The three different extracts contain diverse bioactive compounds that were identified and characterized spectroscopically. Hence, the identification of different biologically active compounds in the extracts of seaweeds justifies further biological and pharmacological...

Medicinal plant identification is necessary for ensuring their efficacy and safety in the quality control of herbal products. The genus Derris belongs to the Leguminosae family. This study aimed to investigate the microscopic characteristics of selected Derris species in Thailand. Eight Derris species (D. amoena, D. elliptica, D. indica, D. malaccensis, D. recticulata, D. scandens, D. solorioides, and D. trifoliata) existing in Thailand were studied. Anatomical characteristics of the leaves were investigated by the midrib transverse section. The laminae were quantitatively investigated for the stomatal number, stomatal index, epidermal cell area, vein islet number, trichome number, and palisade ratio. Trichomes were found in 4 species (D. elliptica, D. scanden, D. amoena and D. malaccensis) which presented as unicellular non-glandular trichome on the lower epidermis. Stomatal type found in Derris species in this study was paracytic type and presented only on lower epidermis, except D. trifoliata which was found on both lower and upper epidermis. The anatomical characteristics of the midrib of eight studied Derris species were illustrated, showing the...
