For the time being, we do not consider aging to be something pathological, so there are no officially recognized therapies or medicines to slow down or even stop the aging process. In the master's thesis, we selected compounds that the "web" claims to slow down aging: resveratrol, metformin, curcumin, rapamycin and nicotinamide adenine dinucleotide.
By creating search profiles for each compound, we identified relevant English-language articles in the PubMed database. The results are presented by individual compound (resveratrol, metformin, curcumin, rapamycin and nicotinamide adenine dinucleotide).
As currently registered active ingredients and dietary supplements have no indication for slowing down aging, we wanted to investigate in the master's thesis whether there is a scientific basis for these claims, even if only on the basis of studies on model organisms. In addition to this, we were interested in the mechanism of slowing down aging.
We found that metformin, rapamycin, and nicotinamide adenine dinucleotide slow down the aging processes in model organisms and that the mechanism of action has been relatively well investigated. According to some studies, resveratrol also slows down the aging of model organisms, but there is more controversy about the mechanism of action, as it acts on several targets. Too few studies have been done for curcumin to be able to draw a similar conclusion as for the first four active ingredients.
It is impossible to apply the results of these studies to humans, therefore to answer the question of whether these active ingredients also have a statistically significant effect on slowing down aging in humans and what the side effects would be. However, since the course of aging is very much related to metabolic activity, some of the mentioned active ingredients or their analogues will become important in the treatment of diabetes, which, along with chronic therapy, may provide an answer to the question of how they affect life expectancy. Finally, in addition to the literature review, we also evaluated the health claims to comment on the link between these compounds and human health.
