, (2019)
A turn-on fluorescent probe for the detection of cysteine (Cys), an essential amino acid in biological systems, is developed based on Cys-mediated O-phenyl benzothioate native chemical ligation (NCL) for the first time. Cys plays important roles in many p

The synthesis of 2'-(6-dimethylamino-2-naphthamide)uridine [U(DAN)] has been described. The nucleoside was converted to the 5'-dimethoxytrityl nucleoside phosphoramidite which could be used for incorporation of U(DAN) into the desired positions of the oligonucleotide sequence.
Two-photon ratiometric fluorescent probe compound for detecting aminopeptidase N, and preparation method thereof

Paragraph 0014, (2019/10/23)
The invention discloses a preparation method of a two-photon ratiometric fluorescent probe compound for detecting aminopeptidase N. The structure of the fluorescent compound is represented by formulaI. The probe compound is designed based on the principle of fluorescence resonance energy transfer, a two-photon naphthalene derivative is selected as an energy donor, a p-methylaminophenol fluorophore is used as an energy acceptor, and alanine is introduced as an aminopeptidase N specific recognition unit. The aminopeptidase N is used to preferentially hydrolyze an N-terminal alanyl group, whichcauses the proportional change in a fluorescence emission signal. The compound has the advantages of high sensitivity, high selectivity, large emission shift, and quickness in detection of the aminopeptidase N, can be successfully applied to two-photon fluorescence imaging in living cells and tissues, and provides a potential tool for clinical detection of kidney injuries.
