In recent years, the adenosineA2Areceptor (A2AR) has shown exciting progress in the development of immunotherapies for the treatment of cancer. Herein, a 2-amino-7,9-dihydro-8H-purin-8-one compound (1) was identified as an A2AR antagonist hit through in-house library screening. Extensive structure–activity relationship (SAR) studies led to the discovery of 2-aminopteridin-7(8H)-one derivatives, which
近年来,腺苷A 2A受体(A 2A R) 在用于治疗癌症的免疫疗法的开发中显示出令人兴奋的进展。在此,一种2-氨基-7,9-二氢-8H-嘌呤-8-酮化合物( 1 )通过内部文库筛选被鉴定为A 2AR拮抗剂。广泛的构效关系 (SAR) 研究导致发现了 2-氨基蝶啶-7(8 H )-one 衍生物,该衍生物在 cAMP 测定中显示出对 A 2A R 的高效力。化合物57在 5'- N处对 A 2A R的 IC 50值为 8.3 ± 0.4 nM-乙基羧酰胺腺苷 (NECA) 水平为 40 nM。即使在 1 μM 的较高 NECA 浓度下, 57的拮抗作用也能持续,这模拟了肿瘤微环境 (TME) 中的腺苷水平。重要的是,57在 IL-2 产生测定和癌细胞杀伤模型中均增强了 T 细胞活化,从而证明了其作为在癌症免疫治疗中开发新型 A 2AR拮抗剂的先导潜力。
