PF-03654764 is an orally active, selective histamine H3 receptor antagonist with Ki values of 1.2 nM and 7.9 nM for human H3 and rat H3 in whole cell assay, respectively. The combination of PF-03654764 and Fexofenadine has the potential for allergic rhinitis research[1][2].
PF-03654764 has pKi values of 8.98 and 8.10 for human H3 and rat H3 in whole cell assay, respectively. PF-03654764 has pKi values of 8.84, 7.73 and Ki values of 1.4 nM and 19 nM for human H3 and rat H3 in HEK-293 cells, respectively. PF-03654764 has >1000-fold selectivity for the H3 receptor over the other histamine receptor subtypes[1]. PF-03654764 has a human liver microsomes (HLM) T1/2 of 120 min and a HLM CLh <5 mL/min•kg[1].
PF-03654764 (10 mL/kg; oral; 14 days) has a Cmax of 8057 ng/mL and an AUC0-24 of 67400 ng•h/mL in Sprague-Dawley rats[1]. PF-03654764 (1 mL/kg; oral; 7 days) has a Cmax of 6302 ng/mL and an AUC0-24 of 18175 ng•h/mL in beagle dogs[1].

工作液浓度: mg/ml;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
