The invention is related to hydroxystyrene derivatives and salts thereof represented by general formula (I)
(wherein
R3 and R4are bound to each othertoform-CONH-CS-S-, (II), (III) or (IV) (wherein R6 is (V) (wherein X' is H, halogen, methyl, ethyl, R7O- (wherein R7 is methyl or ethyl), nitro, aminosulfonyl, or amino and m1 is 1 or 2), pyridyl, furyl or thienyl and n' is an integer of 0 to 3) when R1 and R2 each represents phenyl, benzyl or phenethyl or when R1 represents R50 (wherein R6 is H, C1-C5 alkyl or benzyl) and R2 represents benzyl or PhSCH2; R3 represents cyano and R4 represents carbamoyl or they may be bound to each other to form -CO-Y-CH2CH2- (wherein Y is 0 or-NH) or (VI) when R1 and R2 each represents phenyl, benzyl or phenethyl or R1 represents R50- (wherein R5 is as defined above) and R2 represents benzyl; or R3 and R4 are bound to each other to form (IV) (wherein n1 and R6 are as defined above) when R1 and R2 each represents C1-C3 alkyl). They are useful as effective ingredients of anti-allergic agents, 5-lipoxygenase inhibitors, antibacterial agents, tyrosine kinase inhibitors, UV absorbers, and reverse transcriptase inhibitors, and are also useful as intermediates for many organic compounds.
本发明涉及通式 (I) 所代表的羟基苯乙烯衍生物及其盐类
其中
R3和R4相互结合形成-CONH-CS-S-、(II)、(III)或(IV)(其中R6是(V)(其中X'是H、卤素、甲基、乙基、R7O-(其中R7是甲基或乙基)、硝基、氨基磺酰基或氨基,m1是1或2)、当 R1 和 R2 各自代表苯基、苄基或苯乙基时,或当 R1 代表 R50(其中 R6 为 H、C1-C5 烷基或苄基)且 R2 代表苄基或 PhSCH2 时,或当 R1 代表 R50(其中 R6 为 H、C1-C5 烷基或苄基)且 R2 代表苄基或 PhSCH2当 R1 和 R2 各自代表苯基、苄基或苯乙基时,或当 R1 代表 R50-(其中 R5 如上文所定义)且 R2 代表苄基时,R3 代表氰基且 R4 代表氨基甲酰基;或当 R1 和 R2 各自代表 C1-C3 烷基时,R3 和 R4 相互结合形成 (IV)(其中 n1 和 R6 如上文所定义)。它们可作为抗过敏剂、5-脂氧合酶抑制剂、抗菌剂、酪氨酸激酶抑制剂、紫外线吸收剂和逆转录酶抑制剂的有效成分,也可作为许多有机化合物的中间体。
