According to recent studies from the NIH HIV Reagent Program and the American Society for Microbiology , tazarotene acid is being investigated for the following:
Tazarotene acid is the active carboxylic acid metabolite of the prodrug tazarotene [21]. It functions as a selective retinoid X receptor (RXR) and retinoic acid receptor (RAR) agonist, specifically targeting and RAR- [14]. Key Research Applications 21367.rar
While "21367.rar" might occasionally appear as a generic archive filename in legacy datasets, the number is most prominently associated with this specific biochemical reagent in scientific literature as of early 2026 [14, 21]. According to recent studies from the NIH HIV
: It functions by increasing the expression of CD16 on NK cells, which improves their ability to recognize and destroy infected targets [14]. Technical Specifications Catalog Number 21367 (Commonly via Cayman Chemical) [21] Class : It functions by increasing the expression of
Third-generation retinoid / Retinoic Acid Receptor (RAR) Agonist [14] Enhances NK degranulation and effector function [14] Research Focus
