6-chloro-1,4-diacetoxy-2,3-dimethoxynaphthalene (RS-43179, lonapalene, 11a). An extensive series of 1,2,3,4-tetraoxygenated naphthalenes (16-74) incorporating variations of the ester, ether, and aryl substituents were prepared as analogues of 11a to examine the structural requirements for activity and were screened in vivo as inhibitors of arachidonic acid induced mouse ear edema, a topical bioassay capable
根据先前的观察结果,一系列的2,3-二氢-2,2,3,3-四羟基-1,4-萘醌(氧代磷酸酯,1)和6-氯异萘达沙林(2)在体内均显示出抗银屑病活性,制备了2种结构衍生物,并在Scholtz-Dumas局部牛皮癣生物测定中进行了检查。在这六个(5、6、9a,10、11a,11b)中,发现最有效的化合物是6-氯-1,4-二乙酰氧基-2,3-二甲氧基萘(RS-43179,lonapalene,11a)。制备了广泛的1,2,3,4-四氧化萘(16-74),其中包含酯,醚和芳基取代基的变体,作为11a的类似物,以检查其活性的结构要求,并在体内筛选为抑制剂花生四烯酸引起的小鼠耳部水肿,是一种能够检测5-脂氧合酶抑制剂的局部生物测定法。净亲脂性,水解稳定性和环取代在确定观察到的体内活性中起重要作用。Lonapalene(11a)目前正在作为局部应用的非甾体类抗牛皮癣药物进行临床开发。
