式(II)的中间产物可通过将式(IV)的中间产物用适当的氧化剂如2-苯磺酰-3-苯基-氧杂环丙烷,过氧化氢,叔丁基羟基过氧化物(t-butgl hydroxyperoxide),或间氯过苯甲酸氧化而制备。
所述氧化在反应惰性溶剂中在-20℃-50℃温度间,优选在0℃至室温间进行。适合的溶剂为,例如,水,氯代烃,如二氯甲烷或氯仿;芳香烃,如,甲苯;醇如甲醇;酮,如,4-甲基-2-戊酮,或这些溶剂的混合物。当使用过氧化物氧化剂时,反应速度可通过使用金属催化剂如Na2WO4,VO(乙酰丙酮)2,Ti(OBu)4,或MoO2(乙酰丙酮)2提高反应速度,可任选地在惰性气体如氩气存在下。
式IV的中间产物可通过在存在适当的催化剂如承载在例如碳上的钯、铂情况下用氢还原式(V)的亚胺制备;在反应惰性的溶剂如四氢呋喃,甲醇或这些溶剂的混合物中反应。式(V)的亚胺的制备公开于英国化学会杂志Perk.I.(J.Chem.Soc.Perk.I)(1976),1279。
式(I)的化合物的纯立体化学异构形式可通过应用领域公知的方法获得。非对映体可通过物理方法如选择性结晶和色谱技术,如逆流分布,液相色谱法等予以分离。
按上述方法制备的式(I)的化合物通常为旋光对映体的外消旋混合物,它们可采用领域公知的拆开技术互相分开。足够碱性或酸性的式(I)的外消旋混合物可分别通过与适当的手征性酸如二-1,4-甲苯基-D-酒石酸,或与适当的手征性碱反应而转化为相应的非对映体盐形式。所述非对映体盐形式随后通过例如选择结晶或分级结晶分开,并用碱或酸从其中释放旋光对映体。分离式(I)的化合物的旋光对映体的其它方法包括使用手征性固定相的液相色谱法。所述纯立体化学异构形式也可得自适当起始物质的相应的纯立体化学异构形式,前提条件是反应立体特异地发生。如果需要特定的立体异构体,最好是通过立体特异的制备方法合成所述化合物。这些方法将有利地采用对映异构上纯的起始物质。

本发明因此也涉及按上文所定义的式(I)的化合物用作一种药物,特别是用作治疗上述疾病的药物。
治疗这些疾病的专业人员可从下面给出的试验结果确定有效的每日治疗剂量。有效的每日治疗剂量应为约0.001mg/kg至约10mg/kg体重,更优选约0.005mg/kg至约1mg/kg体重。
为易于用药,本化合物可配制成各种药物形式以供施用。为制备本发明的药物组合物,将治疗有效量的特定化合物,可任选地为加成盐形式,作为活性成分与药学上可接受的载体密切混合,依据用药所希望的制剂形式可采取多种形式。这些药物组合物优选制成适合口服,经直肠,经皮,或胃肠外注射用药的单位剂量形式。例如,在口服剂量形式的组合物制备中,可采用任何常用药物基质。比如,对于口服液体制剂如悬液,糖浆,酏剂和溶液可使用水,甘醇,油,醇类等;对于粉剂,丸剂、胶囊和片剂可使用固体载体如淀粉,蔗糖,高岭土,润滑剂,粘合剂,崩解剂等。由于易于用药,片剂和胶囊代表最有利的口服剂量单位形式,在这种情况下显然采用固体药物载体。对胃肠外组合物,载体通常包含灭菌水,至少大部分为灭菌水,虽然其它成分,比如增加溶解度者,也可包含在内。可注射溶液,可制备为其中载体包含盐水溶液,葡萄糖溶液或盐水和葡萄糖溶液的混合物。包含式(I)的化合物的可注射溶液可在油中配制以提供长效。适合此目的的油为,例如,花生油,芝麻油,棉子油,玉米油,豆油,长链脂肪酸的合成甘油酯和这些和其它油的混合物。也可制备可注射悬液,在这种情况下可采用适当的液体载体,悬浮剂等。在适合经皮用药的组合物中,载体任选地包含穿透促进剂和/或适当的润湿剂,可任选是否与小量的任何性质的次要成分结合使用,这些添加剂不在皮肤上引起任何显著的有害效应。所述添加剂可易化向皮肤的用药和/或可有助于制备所期望的组合物。这些组合物可以多种方式施用,例如,作为透皮肤膏药,作为喷剂(spot-on)或作为软膏。式(I)的化合物的酸或碱加成盐由于它们比相应的碱或酸形式水溶解性高。因而显然更适合制备水性组合物。
为增加式(I)的化合物在药物组合物中的溶解性和/或稳定性,使用α-,β-或γ-环糊精或它们的衍生物会有好处,特别是羟烷基取代的环糊精,如,2-羟丙基-β-环糊精。另外,共溶剂如醇类可提高式(I)的化合物在药物组合物中的溶解性和/或稳定性。
将前述药物组合物配制成剂量单位形式以易于用药和使剂量均匀是特别有利的。本说明书和权利要求书中使用的剂量单位形式指适合作为单元剂量的物理分散单位,每一单位含有经计算能产生期望的治疗效果的预定量的活性成分,以及所需要的药物学载体。这种剂量形式的实例为片剂(包括有划痕或包衣的片剂),胶囊,丸剂,粉包,糯米纸胶囊,可注射溶液或悬液,一茶匙,一餐匙等,和其分离的多重体。
