In Vivo Nanodetoxication for Acute Uranium Exposure

Molecules, 2015
Accidental exposure to uranium is a matter of concern, as U(VI) is nephrotoxic in both human and animal models, and its toxicity is associated to chemical toxicity instead of radioactivity. We synthesized different PAMAM G4 and G5 derivatives in order to

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

Green 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

Molecules, 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

Acta 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

Acta 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 ...
