As a natural metabolite of limonoids from Dictamnus dasycarpus, fraxinellone has been reported to be neuroprotective and anti-inflammatory. However, its influence on cellular metabolism remains largely unknown. In the present study, we investigated the effect of fraxinellone on cellular senescence-induced by oxidative stress and the potential mechanism. We found that fraxinellone administration caused growth arrest and certainly repressed the activity of senescence associated β-galactosidase as well as the expression of senescence-associated-genes. Interestingly, this effect of fraxinellone is closely correlated with the restoration of impaired autophagy and the activation of AMPK. Notably, fraxinellone reacts in an AMPK-dependent but mTORC1-independent manner. Together, our study demonstrates for the first time that fraxinellone has the effect on senescence inhibition and AMPK activation, and supports the notion that autophagic mechanism is important for aging prevention. These findings expanded the list of natural compounds and will be potentially utilized for aging decay and/or AMPK activation. In the experiment, the researchers used many compounds, for example, (3R,3aR)-3-(Furan-3-yl)-3a,7-dimethyl-3a,4,5,6-tetrahydroisobenzofuran-1(3H)-one (cas: 28808-62-0Application of 28808-62-0).
(3R,3aR)-3-(Furan-3-yl)-3a,7-dimethyl-3a,4,5,6-tetrahydroisobenzofuran-1(3H)-one (cas: 28808-62-0) belongs to benzofurans derivatives. Benzofuran is a core structural unit found in many naturally occurring compounds with multidirectional biological activities. They are also prone to polymerisation in the presence of concentrated mineral acids and Lewis acids.Application of 28808-62-0
