  Compounds of formula (I) are useful for the treatment of disease responsive to modulation of CRTH2 receptor activity, such as asthma, rhinitis, allergic airway syndrome, and allergic rhinobronchitis, wherein A represents a carboxyl group —COON, or a carboxyl bioisostere; A 1 , is hydrogen or methyl; ring Ar 1 is an optionally substituted phenyl ring 5- or 6-membered monocyclic heteroaryl ring, in which AA 1 CHO— and L2 are linked to adjacent ring atoms; rings Are 2 , Ar 3 each independently represent a phenyl or 5- or 6-membered monocyclic heteroaryl ring, or a bicyclic ring system consisting of a 5- or 6-membered carbocyclic or heterocyclic ring which is benz-fused or fused to a 5- or 6-membered monocyclic heteroaryl ring, said ring or ring system being optionally substituted; t is 0 or 1; L2 and L3 are linker radicals as defined in the description.

  式(I)的化合物可用于治疗对CRTH2受体活性调节敏感的疾病，例如哮喘、鼻炎、过敏性气道综合症和过敏性鼻支气管炎，其中A代表羧基—COON或羧基生物同位素；A1为氢或甲基；环Ar1是一个可选取代的苯环5-或6-成员的单环杂环，其中AA1CHO—和L2与相邻的环原子连接；环Are2，Ar3各自独立地表示一个苯环或5-或6-成员的单环杂环，或由一个5-或6-成员的碳环或杂环组成的双环系统，该环或环系统被苯并或与一个5-或6-成员的单环杂环融合，该环或环系统是可选取代的；t为0或1；L2和L3是如描述中所定义的连接基团。
• Structure–Activity Relationships and Optimization of 3,5-Dichloropyridine Derivatives As Novel P2X₇Receptor Antagonists

  Screening of a library of chemical compounds showed that the dichloropyridine-based analogue 9 was a novel P2X(7) receptor antagonist. To optimize its activity, we assessed the structure-activity relationships (SAR) of 9, focusing on the hydrazide linker, the dichloropyridine skeleton, and the hydrophobic acyl (R-2) group. We found that the hydrazide linker and the 3,5-disubstituted chlorides in the pyridine skeleton were critical for P2X(7) antagonistic activity and that the presence of hydrophobic polycycloalkyl groups at the R-2 position optimized antagonistic activity. In the EtBr uptake assay in hP2X(7)-expressing HEK293 cells, the optimized antagonists, 5i and 52, had IC50 values of 4.9 and 13 nM, respectively. The antagonistic effects of 51 and 52 were paralleled by their ability to inhibit the release of the pro-inflammatory cytokine, IL-1 beta, by LPS/IFN-gamma/BzATP stimulation of THP-1 cells (IC50 = 1.3 and 9.2 nM, respectively). In addition, 52 strongly inhibited iNOS/COX-2 expression and NO production in THP-1 cells, further indicating that this compound blocks inflammatory signaling and suggesting that the dichloropyridine analogues may be useful in developing P2X(7) receptor targeted anti-inflammatory agents.
