PF-06305591制備如下:將[(1S)-3-氨基-1-(5-叔丁基-1H-苯并咪唑-2-基)-2-甲基-3-氧丙基]氨基甲酸叔丁酯溶液(3.07g)在DCM(50mL)和TFA(10mL)中中攪拌3小時(shí)。加入飽和NaHCO3水溶液(100mL),產(chǎn)物用2-MeTHF(4×100mL)萃取。合并有機(jī)層,用鹽水洗滌,經(jīng)Na2SO4干燥并真空濃縮。使用反相柱色譜法純化殘余物,用0-40%乙腈的水溶液洗脫。將得到的固體在50℃下溶于MeCN(40mL)中,并在使溶液冷卻之前添加甲醇。收集得到的白色沉淀,干燥,并進(jìn)一步用EtOAc(5mL)研磨兩次,得到白色固體PF-06305591。
IC50: 15 nM (NaV1.8).
PF-06305591 (compound 9) has a highly attractive profile with respect to NaV selectivity, hERG activity, passive permeability and in vitro metabolic stability.
PF-06305591 (compound 9) has good rat bioavailability. PF-06305591 offers the possibility of investigating higher IC 50 multiples of Nav1.8 blockade in the clinic, and therefore a more thorough evaluation of the role of NaV1.8 in the treatment of pain.
