Oral bioavailability

AR-42, a new orally bioavailable, potent, hydroxamate-tethered phenylbutyrate class I/IIB histone deacetylase inhibitor currently is under evaluation in phase 1 and 2 clinical trials and has demonstrated activity in both hematologic and solid tumor malignancies. This report focuses on the preclinical characterization of the pharmacokinetics of AR-42 in mice and rats.

Quantifying the multiple processes which control and modulate the extent of oral bioavailability for drug candidates is critical to accurate projection of human pharmacokinetics (PK). Understanding how gut wall metabolism and hepatic elimination factor into first-pass clearance of drugs has improved enormously. Typically, the cytochrome P450s, uridine 5′- diphosphate-glucuronosyltransferases and sulfotransferases, are the main enzyme classes responsible for drug metabolism. Knowledge of the isoforms functionally expressed within organs of first-pass clearance, their anatomical topology (e.

Amyloid-b(Ab) aggregation and amyloid formation are key pathological features of Alzheimer’s disease, and are considered to be two of the major contributing factors to neurodegeneration and dementia. Identification of small molecule inhibitors that are orally available, have low toxicity and high central nervous system bioavailability is one approach to the potential development of a disease-modifying treatment for Alzheimer’s disease.
