The present invention relates to novel compounds which inhibit the action of CXC chemokines, such as IL-8, Gro, NAP-2, ENA-78 etc., on their receptors, to the process for their preparation and to their use for obtaining drugs.
According to the invention, said compounds are novel indole derivatives selected from the group consisting of:
i) the products of the formula
in which:
X is a double bond —C═C— or a sulfur atom;
R1 is a halogen, a nitro group, a trifluoromethyl group or a C1-C3 alkyl group;
R2, R3 and R4 are each independently a hydrogen atom, a halogen, a C1-C3 alkyl group, a nitro group, a trifluoromethyl group or a cyano group, or R2 and R3 form a fused aromatic ring together with the aromatic ring to which they are attached; and
n is equal to 2 or 3; and
ii) esters of the compounds of formula I and addition salts of said compounds with a mineral or organic base.
本发明涉及一种新颖的化合物,该化合物抑制CXC趋化因子(如IL-8、Gro、NAP-2、ENA-78等)对其受体的作用,涉及制备这些化合物的方法及它们用于获得药物的用途。根据本发明,所述化合物是选自以下组合的新型吲哚衍生物:i)式中的产物:其中:X为双键—C═C—或硫原子;R1为卤素、硝基、三氟甲基或C1-C3烷基;R2、R3和R4分别独立地为氢原子、卤素、C1-C3烷基、硝基、三氟甲基或氰基,或R2和R3与它们连接的芳香环一起形成一个融合的芳香环;n为2或3;以及ii)式I的化合物的酯和与矿物或有机碱形成的加合盐。
