A series of pyrido[2,3-d]pyrimidine derivatives were designed and synthesized based on known CC chemokine receptor 4 (CCR4) antagonists. The activities of all the newly synthesized compounds were evaluated using a chemotaxis inhibition assay. Compound 6b was proven to be a potent CCR4 antagonist that can block cell chemotaxis induced by macrophage-derived chemokine (MDC), thymus and activation regulated
基于已知的 CC 趋化因子受体 4 (CCR4) 拮抗剂,设计并合成了一系列吡啶并 [2,3-d] 嘧啶衍生物。使用趋化抑制试验评估所有新合成化合物的活性。化合物 6b 被证明是一种有效的 CCR4 拮抗剂,可以阻断由巨噬细胞衍生的趋化因子 (MDC)、胸腺和活化调节趋化因子 (TARC) 和 CCR4 的天然配体 CKLF1 诱导的细胞趋化性。此外,化合物6b在鼠鼻炎模型中比布地奈德更有效。化合物6b静脉注射LD50为175mg/kg,口服LD50大于2000mg/kg。
