Abstract
本發明提供適用作血紅素之調節劑的化合物及醫藥組合物,其製備之方法及中間物,及其用於治療由血紅素介導之病症及可因組織及/或細胞氧化而受益之病症的方法。
Description
本發明提供適用作血紅素之異位調節劑的化合物及醫藥組合物,其製備之方法及中間物,及其用於治療由血紅素介導之病症及可因組織及/或細胞氧化而受益之病症的方法。
鐮狀細胞病為一種紅血球病症,其尤其在具有非洲及地中海血統者中發現。鐮狀細胞病之原理存在於鐮狀血紅素(HbS)中,相對於血紅素(Hb)之普通肽序列其含有點突變。
血紅素(Hb)自肺輸送氧分子至身體之各種組織及器官。血紅素經由構形變化結合且釋放氧。鐮狀血紅素(HbS)含有點突變,其中麩胺酸經纈胺酸置換,從而使得HbS變得易於聚合而賦予含HbS紅血球其特徵性鐮刀形狀。鐮狀細胞亦比正常紅血球堅硬且其可撓性缺乏可造成血管阻塞。U.S.7,160,910揭示作為血紅素之異位調節劑的化合物。然而,需要可治療由Hb或異常Hb(諸如HbS)介導之病症的其他治療劑。
本發明大體上係關於適用作血紅素之異位調節劑的化合物及醫藥組合物。在一些態樣中,本發明係關於治療由血紅素介導之病症及可因組織及/或細胞氧化而受益之病症的方法。
