Mycochemistry, antioxidant, anticancer activity, and molecular docking of compounds of F12 of ethyl acetate extract of Astraeus asiaticus with BcL2 and Caspase 3 by Swapan Kumar Ghosh, Koushik Pandey, Madhuparna Ghosh, Pradip Kumar Sur

“…Out of them Hexadecanoic acid, 9,12-Octadecadienoic acid and 3,4,5,6 Tetramethyloctane, exhibited suitable properties for drug -preparation and they showed anticancer activity and antioxidant activity as per NIST data base and library search. We have tried to focus on anticancer compounds derived from the partial purification (F12) of mushroom extract (AAEA) from this edible mushroom against cancer (cervical, lung, and breast) cell lines. …”

GC/MS Fatty Acid Profile of Marine-Derived Actinomycetes from Extreme Environments: Chemotaxonomic Insights and Biotechnological Potential by Marlene B. Cunha, André F. Jorge, Maria João Nunes, Joana R. Sousa, Maria João Lança, Marco Gomes da Silva, Susana P. Gaudêncio

“…Fatty acid methyl esters (FAMEs) were prepared from the ethyl acetate lipidic extracts of these strains and analyzed by gas chromatography–mass spectrometry (GC/MS), with FA identification performed using the NIST library. The identified FAs varied from C12:0 to C20:0, where 32 distinct FAs were identified, including 7 branched-chain fatty acids (BCFAs), 9 odd-chain fatty acids (OCFAs), 8 monounsaturated fatty acids (MUFAs), 6 saturated fatty acids (SFAs), 1 polyunsaturated fatty acid (PUFA), and 1 cyclic chain fatty acid (CCFA). …”
