Continuous-Flow Synthesis of the Nucleobase Unit of Remdesivir

open access: yesEngineering, 2023
In this work, the nucleobase unit of the antiviral drug remdesivir, 7-bromopyrrolo[2,1-f][1,2,4]triazin-4-amine, was synthesized through five-step continuous flow.

Transition metal-catalyzed branch-selective hydroformylation of olefins in organic synthesis

open access: yesGreen Synthesis and Catalysis, 2021
Hydroformylation of olefins can generate linear and branched aldehydes, and the branched aldehydes are attractive precursors for the synthesis of fine chemicals and pharmaceuticals.

Removal of 4-Ethylphenol and 4-Ethylguaiacol with Polyaniline-Based Compounds in Wine-Like Model Solutions and Red Wine

open access: yesMolecules, 2015
Volatile phenols, such as 4-ethyphenol (4-EP) and 4-ethylguaiacol (4-EG), are responsible for the “Brett character” found in wines contaminated with Brettanomyces yeast (i.e., barnyard, animal, spicy and smoky aromas).

Development of fluorine-substituted NH2-biphenyl-diarylpyrimidines as highly potent non-nucleoside reverse transcriptase inhibitors: Boosting the safety and metabolic stability

open access: yesActa Pharmaceutica Sinica B, 2023
Our recent studies for nonnucleoside reverse transcriptase inhibitors identified a highly potent compound JK-4b against WT HIV-1 (EC50 = 1.0 nmol/L), but the poor metabolic stability in human liver microsomes (t1/2 = 14.6 min) and insufficient ...

Picomolar inhibitor of reverse transcriptase featuring significantly improved metabolic stability

open access: yesActa Pharmaceutica Sinica B, 2023
Considering the undesirable metabolic stability of our recently identified NNRTI 5 (t1/2 = 96 min) in human liver microsomes, we directed our efforts to improve its metabolic stability by introducing a new favorable hydroxymethyl side chain to the C-5 ...

Structure-based design of novel heterocycle-substituted ATDP analogs as non-nucleoside reverse transcriptase inhibitors with improved selectivity and solubility

open access: yesActa Pharmaceutica Sinica B, 2023
Following on our recently developed biphenyl-ATDP non-nucleoside reverse transcriptase inhibitor ZLM-66 (SI = 2019.80, S = 1.9 μg/mL), a series of novel heterocycle-substituted ATDP derivatives with significantly improved selectivity and solubility were ...

Improving the positional adaptability: structure-based design of biphenyl-substituted diaryltriazines as novel non-nucleoside HIV-1 reverse transcriptase inhibitors

open access: yesActa Pharmaceutica Sinica B, 2020
In order to improve the positional adaptability of our previously reported naphthyl diaryltriazines (NP-DATAs), synthesis of a series of novel biphenyl-substituted diaryltriazines (BP-DATAs) with a flexible side chain attached at the C-6 position is ...
