Based on the efficient application of nitroaromatics in the chemical field, we have developed a novel reaction achieving direct deisopentenylation of i⁶A at the nucleotide level under blue light irradiation with high specific selectively and reaction efficiency. This method provided a photo-controlled intervention mode for the degradation of i⁶A. RNA modifications regulate gene expression and cellular homeostasis. Targeting RNA-modifying enzymes is a promising therapeutic strategy but faces challenges like unidentified enzymes and compensatory mechanisms. Chemical approaches offer alternatives. We have identified 2-chloro-3,5-dinitrobenzoic acid as an effective photochemical deprenylase of i⁶A RNA, converting it to natural adenine, advancing RNA modification biology and therapeutic development.
