(586) Experimental Procedure:
(587) The rodent pharmacokinetic characteristics of the compounds after intravenous injection and oral administration were tested by the standard protocol. In the experiments, the transparent solution was prepared with the compounds to be test. The rats were administered single intravenous injection and oral administration. The solvent for intravenous injection and oral administration was aqueous hydroxypropyl β-cyclodextrin solution or normal saline solution with a certain concentration. Collect the blood samples within 24 hours and centrifuge at 3000 G for 15 minutes. Separate the supernatant to obtain the plasma samples. A volume of acetonitrile solution containing internal standard was added 4 times as the sample to precipitate the protein. The supernatant was obtained after centrifuge. An equal volume of water was added and then centrifuge again to collect the supernatant. The LC-MS/MS method was used to quantitatively analyze the blood drug concentration and the pharmacokinetic parameters such as peak concentration, peak time, clearance rate, half-life period, area under the curve of the drug concentration, and fraction of bioavailability, etc. were calculated.
