Synthetic Route of 1640-39-7, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.1640-39-7, Name is 2,3,3-Trimethylindolenine, molecular formula is C11H13N. In a Article，once mentioned of 1640-39-7
A coumarin-based compound (1) was designed and synthesized as a new turn-on fluorescent probe for the detection of cysteine. The probe exhibited higher selectivity towards the target molecule over other thiol and amino acids at pH 7.2 in aqueous media CH3CN-HEPES (0.02 mol/L, pH 7.2, 1:9, v/v). The reaction mechanism is attributed to the cysteine-induced SNAr substitution-rearrangement reaction. Remarkable enhancement of up to 20-fold in fluorescence intensity was achieved in the detection of cysteine. When applied for the fluorescence imaging of cysteine, the compound 1 emitted a green fluorescence in Hi5 cell cytoplasm. The in vivo imaging of Caenorhabditis elegans had further confirmed the cysteine detection by compound 1.
