“…AP5-derived extract to the neural networking and pharmacophore-based prediction software PASS. This platform has proven successful in its predictions, particularly for those with a probability higher than Pa = 0.5 [ 26 , 48 , 49 , 50 , 51 , 52 , 53 ].…”

Growing data suggest that Aspergillus niger, an endophytic fungus, is a rich source of natural compounds with a wide range of biological properties. This study aimed to examine the antimicrobial and antibiofilm capabilities of the Phragmites australis-derived endophyte against a set of pathogenic bacteria and fungi. The endophytic fungus Aspergillus sp. AP5 was isolated from the leaves of P. australis. The chemical profile of the fungal crude extract was identified by spectroscopic analysis using LC-HRESIMS. The fungal-derived extract was evaluated for its antimicrobial activity towards a set of pathogenic bacterial and fungal strains including Staphylococcus aureus, Pseudomonas aeruginosa, Proteus vulgaris, Klebsiella sp., Candida albicans, and Aspergillus niger. Moreover, antibiofilm activity toward four resistant biofilm-forming bacteria was also evaluated. Additionally, a neural-networking pharmacophore-based visual screening predicted the most probable bioactive compounds in the obtained extract. The AP5-EtOAc extract was found to have potent antibacterial activities against S. aureus, E. coli, and Klebsiella sp., while it exhibited low antibacterial activity toward P. Vulgaris and P. aeruginosa and displayed anticandidal activity. The AP5-EtOAc extract had significant antibiofilm activity in S. aureus, followed by P. aeruginosa. The active metabolites’ antifungal and/or antibacterial activities may be due to targeting the fungal CYP 51 and/or the bacterial Gyr-B.

“…Accordingly, we subjected the metabolites (1-25) identified in the P. lamellosa-derived extracts (i.e., CE and EE) to the neural networking-based prediction software PASS. This software has shown very good success rate in its predictions, particularly for predictions higher than Pa = 0.5 [27][28][29][30][31][32][33].…”

“…Moreover, they showed a number of hydrophobic interactions with LEU-5, MET-21, HIS-46, TYR-50, and LYS-6 (Figure 6). sPLA2 has been reported to have a crucial role in the growth and development of different types of human cancers (e.g., breast, prostate, liver, and skin), and identified to be a promising target to control these types of tumors [24][25][26][27][28][29][30][31][32][33][34][35].…”

“…It is worth noting that the compounds 1-15 have also shown to be COX inhibitors according to PASS prediction; however, their scoring was poor (Pa < 0.5) (Figure 7). sPLA2 has been reported to have a crucial role in the growth and development of different types of human cancers (e.g., breast, prostate, liver, and skin), and identified to be a promising target to control these types of tumors [22,[24][25][26][27][28][29][30][31][32][33][34].…”

Background: The Red Sea sponges have been endorsed as a plentiful source of bioactive compounds with promising anti-cancer and anti-inflammatory activities; therefore, exploring their potential as a source of anti-cancer metabolites has stimulated a growing research interest. Purpose: To investigate the anti-cancer and anti-inflammatory potential of the Red Sea sponges, in their bulk and silver nanostructure. Metabolomics analysis of the selected sponge followed by molecular docking studies, will be conducted to explore and predict the secondary metabolites that might provide its capability of inhibiting cancer. Materials and Methods: We prepared a chloroform extract (CE) and ethyl acetate extract (EE) of the Red Sea sponge Phyllospongia lamellosa synthesized silver nanoparticles. The prepared silver nanoparticles were characterized through UV–vis spectrophotometric, transmission electron microscopy (TEM), and Fourier-transform infrared spectroscopy (FTIR) analyses. Testing for their anti-cancer activities was performed against MCF-7, MDB-231, and MCF-10A cells. Anti-inflammatory activity against COX-1 and 2 was assessed. Furthermore, liquid chromatography–mass spectrometry (LC–MS)-based metabolomics analysis and molecular docking were also applied.

“…18,22 On the other hand, despite their chemical and biological prolicacy, the biogenic synthesis of AgNPs using marine invertebrates has been scarcely explored, 23 encompassing our recent report on the anti-inammatory potential of the biosynthesized AgNPs from the so coral Nephthea sp., which revealed greater anti-COX-2 properties compared with its bulk extracts. 24 Therefore, in continuation of our interest in marine organisms and their bioactive NPs, [24][25][26][27][28] the current study investigates the chemical complexity and anti-proliferative activity of the total extract and different fractions of Nephthea sp., along with the green synthesis of potential anti-proliferative AgNPs using the total so coral extract. Molecular docking analysis was also considered in order to predict the possible binding of the identied metabolites to a number of cancerrelated cellular proteins.…”
