司替戊醇(斯利潘托)的作用機(jī)制比較獨(dú)特,既可以增加GABA釋放,又可以抑制某些酶的活性、從而提高其他抗癲癇藥的血藥濃度。司替戊醇(斯利潘托)于2001 年在歐盟獲得批準(zhǔn),用于輔助治療嚴(yán)重的嬰兒型癲癇肌陣攣發(fā)作。
司替戊醇(斯利潘托)治療的不良反應(yīng)主要是由其對(duì)其他藥物的增效作用所導(dǎo)致的,與丙戊酸鈉合用可能會(huì)增加丙戊酸鈉的惡心和嘔吐發(fā)生率。
一種司替戊醇(斯利潘托)的制備方法,包括以下步驟:
(1)將120g胡椒醛投入0.2L乙醇與2.4L蒸餾水的混合溶劑中,加入160g固體NaOH、2.6g芐基三丁基氯化銨和120g甲基叔丁酮,于40℃攪拌反應(yīng)。TLC檢測反應(yīng)(展開劑:石油醚?乙酸乙酯(6:1)),16h后反應(yīng)完全。將反應(yīng)液冷卻至室溫,減壓抽濾,濾餅用0.12L無水乙醇進(jìn)行重結(jié)晶,干燥,得到黃色針狀結(jié)晶4,4?二甲基?1?[(3,4?亞甲二氧基)?苯基]?1?戊烯?3?酮(172.5g,93.2%),m.p. 93.7~95.1℃。ESI?MS(m/z): 233.1[M+H]+,255.1[M+Na]+。
(2)將步驟(1)得到的4,4?二甲基?1?[(3,4?亞甲二氧基)?苯基]?1?戊烯?3?酮投入0.8L乙醇中,在25~40℃攪拌下,10分鐘內(nèi)分批加入硼氫化鈉14.8g,分批加入硼氫化鈉可以避免局部濃度過高造成的反應(yīng)不均勻,再加入0.08L丙酮和0.12L蒸餾水,50℃下攪拌5分鐘,有氣泡產(chǎn)生,待氣泡消失后,繼續(xù)加水,有固體析出,待固體析出完全后,冷卻至室溫,減壓抽濾,濾餅用0.15L無水乙醇進(jìn)行重結(jié)晶,干燥,得到白色晶體司替戊醇(斯利潘托)共(91.1g,93.7%)。
IC50: 1.58 μM (CYP3A4), 3.29 μM (CYP2C19)
Ki: 1.59±0.07μM (CYP3A4), 0.516±0.065 μM (CYP2C19)
Stiripentol (STP) is an anticonvulsant agent, which can inhibit N-demethylation of CLB to N-desmethylclobazam (NCLB) mediated by CYP3A4 (noncompetitively) and CYP2C19 (competitively). The inhibition of CLB demethylation by Stiripentol (STP) is best described by a noncompetitive inhibition model with apparent K i =1.6 μM for the cDNA-expressing CYP3A4 and by a competitive inhibition model with K i =0.52 μM for the cDNA-expressing CYP2C19. Formation of OH-NCLB from NCLB by cDNA-expressing CYP2C19 is competitively inhibited by Stiripentol (STP) with a K i =0.14 μM.
In mice treating with Stiripentol (STP) monotherapy, the difference between BT 1 (39.67±1.09°C) and BT 2 (41.32±1.05°C) reaches statistical significance (t=3.097, p<0.05). The difference in BT 2 between Stiripentol (STP) monotherapy and CLB monotherapy is statistically significant (t=2.615, p<0.05). In mice treating with Stiripentol (STP)+CLB combination therapy, the difference between BT 1 (40.18±0.58°C) and BT 2 (43.03±0.49°C) reaches statistical significance (t=10.44, p<0.01).
