-
Paragraph 0089-0093, (2021/09/01)
The invention relates to N4 - hydroxycytidine derivatives as shown in general formula I. A pharmaceutically acceptable salt, a tautomer thereof, a stereoisomer thereof, a metabolite thereof, a metabolic precursor thereof, or a prodrug thereof, and the substituted N4 - hydroxycytidine derivative structure of the structure of Formula I. The pharmaceutical composition is used for preparing medicaments for treating infections such as SARS-CoV, HBV, HCV, H1N1, Ebola and SARS-CoV - 2, can effectively inhibit influenza viruses and SARS-CoV - 2 viruses, and can have the same result on other RNA viruses. The series of compounds can be applied to preparation of anti RNA virus drugs. The medicine is used for preparing a medicine for treating virus infection and is used for preparing a vaccine adjuvant for treating virus infection.

Liposome Enhanced Detection of Amyloid Protein Aggregates

Thioflavin-T is used to image amyloid aggregates because of the excellent turn-on fluorescence properties, but binding affinities are low. By mounting multiple dye units on the surface of a vesicle, the binding affinity for α-synuclein fibrils is increased by three orders of magnitude, and the optical response is increased. Cooperative interactions of the dye headgroup and lipid with the protein provide a general strategy for the construction of multivalent amyloid probes based on vesicles.
