Pharmacokinetic Study of Epothilones

The PK study was conducted by Pharmacelsus GmbH. These experimental procedures were approved by and conducted in accordance with the regulations of the local Animal Welfare authorities (Landesamt für Gesundheit und Verbraucherschutz, Abteilung Lebensmittel- und Veterinärwesen, Saarbrücken). Rats were injected subcutaneously (s.c.) or intraperitoneally (i.p.) with epoD (1.5 mg/kg; Abcam, ab143616), epoB (0.75 mg/kg; Selleck Chemicals S1364) or ixabepilone (0.75 or 1.5 mg/kg; Ixempra Cay23732-10). Drugs were diluted in 50% dimethyl sulfoxide (DMSO)/saline. Animals were euthanized at 6 h, 1, 7 or 14 days after injections and blood plasma and spinal cord tissue samples were collected. Three animals per time point and group were used, for a total of 72 used in the PK study. Drug concentrations in the samples were quantified by liquid chromatography–mass spectrometry (LC–MS) using an Accela 1250 UHPLC (Ultra High Performance Liquid Chromatography) system, Accela Open Autosampler and Q-Exactive mass spectrometer (Thermo Fisher Scientific).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
