There are described pharmacologically active compounds, useful in the treatment of allergic/inflammatory disorders involving SRS-A as causal mediator and which, in free acid form, are of formula I,
in which R1 is
(i) an aliphatic, saturated or unsaturated hydrocarbyl radical of up to 20 carbon atoms, unsubstituted or substituted by at least one substituent selected from halogen, hydroxy, C3-6 alkoxy, C3-6 cycloalkyl, aryl or heteroaryl, the cycloalkyl, aryl or heteroaryl being unsubstituted or substituted by at least one substituent selected from hydroxy, halogen and alkyl, alkenyl or alkynyl of up to 10 carbon atoms,
(ii) cycloalkyl of 3 to 8 carbon atoms unsubstituted or substituted by alkyl, alkenyl or alkynyl of up to 16 carbon atoms, or
(iii) aryl or heteroaryl, unsubstituted or substituted by hydroxyl, C1-4 alkoxy, halogen or alkyl, alkenyl or alkynyl of up to 16 carbon atoms;
and R2 is
(i) alkyl, cycloalkyl or alkenyl of up to 10 carbon atoms, unsubstituted or substituted by one or more substituents selected from aryl, cycloalkyl, halogen, hydroxy, NHR3 and COX, where R3 is H, C1-4 alkyl, aryl or an amino acid residue or COX, and X is OH, C1-4 alkyl, NH2 or an amino acid residue, or (ii) aryl or heteroaryl, unsubstituted or substituted by one or more substituents selected from C1-4 alkyl, C1-4 alkoxy, C2-5 acyl, halogen, hydroxy, carboxy, nitro, trihalomethyl, phenyl, C1-4 acylamino and NHR4, where R4 is hydrogen or C1-4 alkyl; and Y is -S-, -SO- or -S02-,
with the proviso that when -YR2 is glutathionyl, cysteinyl or cysteinylglycinyl, then R1 is other than an unsubstituted alkatetraenyl or alkapentaenyl radical of 12 to 16 carbon atoms.
所述化合物具有药理活性,可用于治疗以 SRS-A 为病因介质的过敏性/炎症性疾病,其游离酸形式如式 I 所示、
其中 R1 是
(i) 脂肪族、饱和或不饱和烃基,碳原子数不超过 20 个,未被取代或被至少一个选自卤素、羟基、C3-6 烷氧基、C3-6 环烷基、芳基或杂芳基的取代基取代,环烷基、芳基或杂芳基未被取代或被至少一个选自羟基、卤素和碳原子数不超过 10 个的烷基、烯基或炔基的取代基取代、
(ii) 未被或被不超过 16 个碳原子的烷基、烯基或炔基取代的 3 至 8 个碳原子的环烷基,或
(iii) 芳基或杂芳基,未被或被羟基、C1-4 烷氧基、卤素或最多 16 个碳原子的烷基、烯基或炔基取代;
而 R2 是
(i) 碳原子数不超过 10 的烷基、环烷基或烯基,未被取代或被选自芳基、环烷基、卤素、羟基、NHR3 和 COX 的一个或多个取代基取代,其中 R3 是 H、C1-4 烷基、芳基或氨基酸残基或 COX,X 是 OH、C1-4 烷基、NH2 或氨基酸残基、NH2 或氨基酸残基,或 (ii) 芳基或杂芳基,未被取代或被一个或多个选自 C1-4 烷基、C1-4 烷氧基、C2-5 乙酰基、卤素、羟基、羧基、硝基、三卤甲基、苯基、C1-4 乙酰氨基和 NHR4 的取代基取代,其中 R4 是氢或 C1-4 烷基;Y为-S-、-SO-或-S02-、
但当-YR2 为谷胱甘肽基、半胱氨酸基或半胱氨酰甘氨酰时,R1 不是 12 至 16 个碳原子的未取代烷四烯基或烷五烯基。
