Pharmacokinetics of panobinostat: Inter-species difference in metabolic stability [Metabolism, Transport, and Pharmacogenetics]

ASPET

Panobinostat also showed inter-strain and inter-species differences in the in vitro plasma stability; and was stable in human plasma. Importantly, the plasma stability in various mouse strains was not reflected in the in vivo systemic pharmacokinetic behavior of panobinostat.

Covalent Stapling of the Cereblon Sensor Loop Histidine Using Sulfur-Heterocycle Exchange

Covalent Modifiers

Attenuation of intrinsic reactivity through the development of sulfonyl pyrazoles, imidazoles, and nucleobases enhanced plasma stability, and several compounds retained efficient labeling of His353.

Predicting the Intravenous Pharmacokinetics of Covalent Drugs in Animals and Humans

Covalent Modifiers

Improved quantitative performance was observed by combining metabolic stability data from LMs and liver S9 fractions, the latter supplemented with reduced glutathione for glutathione transferase activity.

Pharmacokinetic study of the interaction between luteolin and magnoflorine in rats

Chemical Biology and Drug Design

Magnoflorine increased the systemic exposure and metabolic stability and suppressed the transport of luteolin. CaCO-2 cell transwell assay was employed for transport evaluation, and the metabolic stability of luteolin and CYP3A activity were assessed in rat liver microsomes.

Effect of ophiopogonin D on the pharmacokinetics and transport of cryptotanshinone during their co?administration and the potential mechanism

Chemical Biology and Drug Design

The co-administration of cryptotanshinone with ophiopogonin D induced pharmacokinetic interaction prolonging the systemic exposure and improving metabolic stability of cryptotanshinone. The Caco-2 cells were employed to evaluate the transport of cryptotanshinone, and the metabolic stability was studied in the rat liver microsomes.

Evaluation of Systemic and Brain Pharmacokinetic Parameters for Repurposing Metformin Using Intravenous Bolus Administration [Drug Discovery and Translational Medicine]

ASPET

In vitro assays examined brain tissue binding and metabolic stability. The findings highlight metformin's rapid brain entry, minimal binding, and metabolic stability. An LC-MS/MS method to measure metformin levels in plasma, brain, and cerebrospinal fluid (CSF) was developed and validated.
