Abstract
取代的4-(喹啉-2-基-甲氧基)苯乙酸衍生物能从相应的4-(喹啉-2-基-甲氧基)苯乙酸酯来制备。该类新的化合物能用作5-脂肪氧合酶的抑制剂。
Description
本发明涉及新的取代的4-(喹啉-2-基-甲氧基)苯乙酸及其酯和酰胺,并涉及它们的制备方法及其在医药上的用途。
已知3-(喹啉-2-基-甲氧基)苯乙酸和2-〔3-(喹啉-2-基-甲氧基)苯基〕丙酸及其甲酯和乙酯具有消炎和抗过敏作用〔参见EP-All181,568〕。
我们提供新的具有通式(Ⅰ)的4-)喹啉-2-基-甲氧基)苯乙酸及其酯和酰胺和它们的盐类:
其中R1表示下式基团:
其中R2和R3可以相同也可以不同,并且表示为氢、烷基、芳基、芳烷基或下式基团:
其中R4表示为氢、能被羟基、羧基、烷氧羰基、烷硫基、杂芳基或氨基甲酰基任意取代的烷基、芳烷基或芳基,
R5表示为氢、烷基、芳基或芳烷基,
R6表示式-COR5或-CO2R5基团,其中R5具有上述定义,
R7表示为氢、烷基或芳基,
Y表示下式基团
其中R8表示为氢、烷基或芳基和n代表从0至5的一个数字。
Z表示降冰片基(norbornyl)或表示为下式基团:
其中R9和R10可以相同或不同,并且表示为氢、烷基或芳基,或
R9和R10能合起来形成一个具有直至6个碳原子的饱和碳环和
m代表从1至6的一个数字,和
A和B可以相同或不同,并且表示为氢、低级烷基或卤素。
按本发明的通式(Ⅰ)喹啉同EP-A 181,568中揭示的已知化合物相比较,意想不到的是前者具有高于白三烯合成抑制剂的体外活性,并且通过口服给药在体内的作用更有效。
烷基通常表示为具有1至12个碳原子的直链或支链烃基,优选的是具有1至约6个碳原子的低级烷基。它们的实例可以是提到的甲基、乙基、丙基、异丙基、丁基、叔丁基、异丁基、戊基、异戊基、己基、异己基、庚基、异庚基、辛基、异辛基。
