Description: SKQ1, also known as Visomitin, plastoquinonyl decyltriphenyl phosphonium or PDTP, is a potent mitochondria-targeted antioxidant. SKQ1 is also an API for making eye drop drug called Visomitin. SKQ1 showed activities (1) to prevent amyloid-β-induced impairment of long-term potentiation in rat hippocampal slices; (2) to reverse aging-related biomarkers in rats; (3) to slow down the development of age-dependent destructive processes in retina and vascular layer of eyes of wistar and OXYS rats; (4) to increase the lifespan of male rodents under LP or SPF conditions. SKQ1 can penetrate cell membranes , and is proposed as an anti-aging treatment. Visomitin, which API is SKQ1, is currently under clinical trials for treating glaucoma in Russia. Note: For the convenience of use, SKQ1 is supplied as solution of 200mg / mL in ethanol-water (1:1, v/v).

Recent Work on SkQ1 and Vascular Inflammation: SkQ1 is a mitochondrially targeted antioxidant, and there is evidence to show that it can modestly extend life in mice. Mitochondria are important in the aging process, and one of the ways in which they interact with surrounding cell biology is by generating damaging reactive oxygen species (ROS). Too much ROS creation can harm a cell, a state called oxidative stress. Just a little more than usual can be beneficial, as the cell reacts with increased housekeeping for a net benefit - this is probably one of the mechanisms by which exercise improves health, for example. This signaling is a parallel mechanism to the most important harm likely caused by mitochondrial ROS, however, which is to damage mitochondrial DNA at their point of origin. This can lead to all sorts of persistent dysfunction in a small population of cells, which export harmful molecules to surrounding tissues. Mitochondrial antioxidants probably produce benefits to long term health by reducing the rate of this mitochondrial damage, but that isn't completely certain at this point because of the ROS signaling to other important aspects of cell metabolism. Biology is complex, and as for all small effects on longevity, the actual mechanism could be any one of a number of things.  So these researchers are making use of SkQ1 as a way to better identify what exactly it is that changes in response to ROS levels, with a focus on dysfunction in blood vessel wall tissue (the vascular endothelium) that leads to age-related conditions such as atherosclerosis.
