Plastoquinonyl decyltriphenylphosphonium bromide (PDTF) is a plastoquinone derivative which, through a linker chain (C10), is linked to a triphenylphosphine residue. PDT in low (nanomolar) concentrations shows high antioxidant activity. It also has a stimulating effect on the process of tear production, epithelization, and improves the stability of tear film.
One of the reasons for the development of age-related cataracts is the damaging effect of ultraviolet radiation, which initiates photo-oxidation processes, leading to denaturation of the main structural component of the crystalline lens.The first protection of the eye tissues from ultraviolet radiation is a tear fluid that absorbs ultraviolet light in the range of 240-320 nm and neutralizes it due to the components of the antioxidant activity of tear fluid. According to the data of the preclinical study, the antiscaractal action of the drug Visomitin ® is associated with an increase in the level of expression of the main proteins of the crystalline lens, the restoration of the lens epithelium and the activation of energy processes in it. According to the clinical study, in patients with age-related cataracts using the drug Visomitin®, an increase in the antioxidant activity of tears was noted.
