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。

The use of the "borrowing hydrogen strategy" in the synthesis of a number of typical pharmaceutical intermediates has been investigated. The main aim of this work was to investigate the scope and limitations of current methodology using standard laboratory techniques in an industrial context. Some interesting and significant results were achieved across a diverse set of complex substrates; however several drawbacks with this approach were identified, such as the high loading, poor turnover, and susceptibility to substrate inactivation of the catalysts. These are areas which are highlighted for future investigation and improvements.
