  α,β-Methylene-ADP (AOPCP) Derivatives and Analogues: Development of Potent and Selective ecto-5′-Nucleotidase (CD73) Inhibitors

  摘要：

  ecto-5'-Nucleotidase (eN, CD73) catalyzes the hydrolysis of extracellular AMP to adenosine. eN inhibitors have potential for use as cancer therapeutics. The eN inhibitor alpha,beta-methylene-ADP (AOPCP, adenosine-5'-O-[(phosphonomethyl)phosphonic acid]) was used as a lead structure, and derivatives modified in various positions were prepared. Products were tested at rat recombinant eN. 6-(Ar)alkylamino substitution led to the largest improvement in potency. N-6-Monosubstitution was superior to symmetrical N-6,N-6-disubstitution. The most potent inhibitors were N-6-(4chlorobenzyl)-(10l, PSB-12441, K-i 7.23 n.M), N-6-phenylethyl(10h, PSB-12425, K-i 8.04 nM), and N-6-benzyl-adenosine-5'-O[(phosphonomethyl)phosphonic acid] (10g, PSB-12379, K-i 9.03 nM). Replacement of the 6-NH group in 10g by 0 (10q, PSB-12431) or S (10r, PSB-12553) yielded equally potent inhibitors (10q, 9.20 nM; 10r, 9.50 aM). Selected compounds investigated at the human enzyme did not show species differences; they displayed high selectivity versus other ecto-nudeotidases and ADP-activated P2Y receptors. Moreover, high metabolic stability was observed. These compounds represent the most potent eN inhibitors described to date.

• Synthesis of a Cytokinin Linked by a Spacer to Dexamethasone and Biotin: Conjugates to Detect Cytokinin-Binding Proteins
  作者：You Wang、David Letham、Peter John、Ren Zhang

  DOI：10.3390/molecules21050576

  日期：——

  (e.g., dexamethasone) linked to a cytokinin via a spacer. In the yeast nucleus, this ligand by binding connects two fusion proteins leading to a reporter gene activation and detection and characterisation of cytokinin binding proteins. Herein is reported the first synthesis of dexamethasone-cytokinin ligands with a spacer linkage. This was attached to the purine ring of 6-benzylaminopurine (BAP) at positions

  表达cDNA文库的酵母细胞提供了两种新方法，以促进进一步鉴定细胞分裂素结合蛋白和受体。这些是酵母三杂交（Y3H）系统和荧光激活细胞分选（FACS）。Y3H系统需要合成的杂合配体，该杂合的配体包含通过间隔子与细胞分裂素连接的“锚”部分（例如地塞米松）。在酵母核中，该配体通过结合连接两个融合蛋白，从而导致报告基因激活以及细胞分裂素结合蛋白的检测和表征。本文报道了具有间隔键的地塞米松-细胞分裂素配体的首次合成。将其连接至6，苄基氨基嘌呤（BAP）的嘌呤环的2、8或9位。要实现这一点，地塞米松通过高碘酸盐氧化进行修饰，产生用于通过酰胺形成与间隔基缀合的羧基。用于FACS的细胞分裂素的生物素衍生物包括通过生物素的活化酯与BAP的8-（10-氨基-癸基氨基）衍生物和BAP 9-核糖苷反应合成的那些。简要讨论了结合物的性质和一些可能适用的生物学情况。
