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.
本发明涉及一种新型化合物,其抑制CXC趋化因子(如IL-8,Gro,NAP-2,ENA-78等)在其受体上的作用,以及其制备过程和用于获得药物的用途。根据本发明,所述化合物是选自以下化合物组的新型吲哚衍生物:i)公式中的产物
其中,X是双键—C═C—或硫原子;R1是卤素,硝基,三氟甲基或C1-C3烷基;R2、R3和R4分别独立地是氢原子,卤素,C1-C3烷基,硝基,三氟甲基或氰基,或R2和R3与它们所连接的芳环一起形成融合芳环;n等于2或3;以及ii)公式I化合物的酯和该化合物与矿物质或有机碱的加成盐。
