Studysummary This study found that the leaf extract of Tectona grandis and its major bioactive constituents moderately inhibit the 5α-reductase enzyme, which is linked to androgenetic alopecia, and also possess anti-inflammatory properties, showing promise as dual-action candidates for managing this condition. Our plain-language summary of this paper — not a Tressless recommendation.
The study on Tectona grandis L.f. leaves and its major bioactive constituents, (+)-Eperua-8,13-dien-15-oic acid and (+)-Eperua-7,13-dien-15-oic acid, reveals their potential in managing androgenetic alopecia (AGA) through moderate inhibition of the steroid 5α-reductase enzyme, with binding affinities of −8.01 and −8.81 kcal/mol, respectively. Additionally, these compounds exhibit anti-inflammatory properties by inhibiting nitric oxide and pro-inflammatory cytokines IL-1β and IL-6. Notably, (+)-Eperua-7,13-dien-15-oic acid shows a stronger binding affinity to endothelial nitric oxide synthase and selective inhibition of IL-6, suggesting these compounds as promising candidates for dual-action treatment targeting both 5α-reductase activity and cytokine-mediated inflammation in AGA management.
