Enhanced doxorubicin delivery to the brain administered through glutathione PEGylated liposomal doxorubicin (2B3-101) as compared with generic Caelyx,(®)/Doxil(®)--a cerebral open flow microperfusion pilot study.

abstract：:Determining the aggregation propensity of protein-based biotherapeutics is an important step in the drug development process. Typically, a great deal of data collected over a large period of time is needed to estimate the aggregation propensity of biotherapeutics. Thus, candidates cannot be screened early on for aggre...

abstract：:Oxycodone is an opioid analgesic that is administered orally or parenterally. The time-course of opioid action is a function of the systemic kinetics of the opioid, and the rate and extent of its entry into the brain and central nervous system. The latter is incompletely understood for oxycodone. Therefore, the cerebr...
