Nigericin is an antibiotic derived from Streptomyces hygroscopicus that acts as a K+ H+ ionophore, promoting K+ H+ exchange across mitochondrial membranes. Nigericin can be an NLRP3 activator that causes the release of IL-1β as a NALP3-dependent manner. N
Tropodithietic acid, a sulfur-containing antibiotic produced by the marine bacterium Phaeobacter inhibens, exhibits potent antibiotic efficacy across a diverse array of bacteria, encompassing alpha- and gammaproteobacteria, flavobacteria, and actinobacteria.
6'7'-Epoxybergamottin is a furanocoumarin found in grapefruit. It is a potent inhibitor of the cytochrome P450 (CYP) isoform CYP3A4 with an IC50 value of 0.30 ppm in a cell-free assay, 0.33 μM in HL7 human liver cells, and 0.22 μM in S9 human intestine cells. It has been studied in the context of drug interactions with grapefruit constituents. It is found in grapefruit juice at concentrations of 0.1-7.4 μM and inhibits the transport of talinolol , a permeability glycoprotein (P-gp/ABCB1) transporter substrate, across Caco-2 cell monolayers (IC50 = 0.7 μM). 6'7'-Epoxybergamottin also has insecticidal properties with a concentration of 5 μg/cm2 leading to 100% mortality of adult olive fruit flies.
The binding affinities of ganoderic acid DM andGanoderic acid ζ (ÎGbind, -16.83 and-10.99 kcal mol-1) are comparable to that of current commercial drug oseltamivir (-23.62 kcal mol-1);Ganoderic acid DM is a potential source of anti-influenza ingredient, with novel binding pattern and advantage over oseltamivir, it has steric hindrance on the 150 cavity of N1 protein, and exerts activities across the H274Y and N294S mutations, is the attractive candidates of novel neuraminidase (NA) inhibitors.Ganoderic acid zeta has cytotoxicity in vitro against Meth-A and LLC cell lines.
Cognac oil, predominantly derived from wine lees, exhibits distinctive fatty acid compositions, characterized by high proportions of Palmitic acid (59.26%), Linoleic acid (11.92%), Myristic acid (8.97%), and Oleic acid (8.3%) among other fatty acids. Notably, the application of Cognac oil enhances the permeability of Rhodamine 6G (R6G) across various membranes, resulting in a generalized increase in permeation.
α-Farnesene, a sesquiterpene, is a herbivore-induced plant volatile (HIPV) that plays a significant role in insect resistance across various plant species.
