Discovery of deoxyandrographolide and its novel effect on vascular senescence by targeting HDAC1.

(Fuzi) is a traditional Chinese medicine that has been widely used in the clinic to save the dying life for over several thousand years. However, the medicinal components of Fuzi in treating vascular senescence (VS) and its potential mechanism remain unclear. In this study, a network pharmacology method was used to explore the possible components and further validated by experiments to get a candidate compound, deoxyandrographolide (DA).

Development and validation of a simple and sensitive high-resolution LC/MS method for determination of PF-04620110 in dog plasma: Application to a pharmacokinetic study.

In this study, a more sensitive and reliable quantitative method based on ultra-high performance liquid chromatography coupled with Q-Exactive-Orbitrap-MS in full-mass scan was developed and validated for the determination of PF-04620110 in dog plasma. After protein precipitation with acetonitrile, the sample separations were carried out on an Acquity BEH C column with 1 mm ammonium acetate in water and acetonitrile containing 0.1% acetic acid as mobile phase, at a flow rate of 0.
