Efficacy of derinat as a treatment for murine and androgenetic alopecia (AGA) patients

Abstract Background Androgenetic alopecia (AGA), one of the most common types of hair loss, is associated with oxidative stress, inflammation and aging. Derinat, a transient receptor potential canonical channels (TRPCs) inhibitor, restrains TRPCs-mediated increase intracellular Ca 2+ signaling, which initiates the skin aging process with intracellular reactive oxygen species (ROS) accumulation. This study investigated whether Derinat protected skin from oxidative stress-induced damage and aging, thus inhibiting AGA pathogenesis. Methods The lifespan of Caenorhabditis elegans was measured to examine the capacity of Derinat to oppose the oxidative stress induced-aging process, which drives the hair cycle from anagen to catagen phase. The experiments that used BALB/c-nu and C57BL/6 mice determined the effects of Derinat on hair cycle and oxidative stress in skin. To further apply Derinat to clinical study, the resulting relationship between AGA pathogenesis and TRPCs-regulated oxidative stress was confirmed using the bioinformatics approach. We consequently used the parameters of hair density, hair diameter, hair recovery and quality of life index to evaluate the effect of Derinat treatment on AGA subjects. Results Derinat restrained the oxidative stress induced-aging process sufficiently to extend the lifespan of worms. Derinat also changed the hair growth patterns of mice by maintenance of the hair cycle at the anagen phase. This efficacy was due to reduction of TRPCs-mediated ROS accumulation. Because the bioinformatics analysis found that AGA pathogenesis is associated with TRPCs-regulated oxidative stress and inflammation, treatment with Derinat in AGA subjects increased positive outcomes of oral medication while mitigating the impairment of AGA subjects’ quality of life. Conclusions Derinat restrains AGA pathogenesis and may provide a new therapeutic approach for treating AGA.
