Description

RTA-408 is a synthetic triterpenoid that potently activates the antioxidative transcription factor Nrf2 and inhibits the proinflammatory transcription factor NF-κB. IC50 value: Target: Nrf2 activator Mice were irradiated (10 Gy/day) on days 0-2 and 5-7, and RTA 408 (0.01%, 0.1% and 1.0%) was topically applied once daily starting on day 5 or up to day 40. Dermatitis severity was evaluated using a scale ranging from 0 (normal) to 5 (frank ulceration), as well as histologically. The mRNA expression of Nrf2 and NF-κB target genes in skin was also evaluated. RTA 408 (0.01%, 0.1% and 1.0%) reduced the percentage of animal-days with scores ≥2 by 11%, 31% and 55% and scores ≥3 by 16%, 60% and 80%, respectively [1]. RTA 408 (0.1, 1.0, or 3.0%) was applied topically to the shaved skin of male Sprague-Dawley rats twice daily for 4 days and once on Day 5. Topical application of RTA 408 resulted in transdermal penetration, with low but dose-dependent plasma exposure with AUC(0-24 h) values of 3.6, 26.0, and 41.1 h ng/mL for the 0.1, 1.0, and 3.0% doses, respectively [2].
