  4-Alkyloxyimino-cytosine nucleotides: tethering approaches to molecular probes for the P2Y6 receptor

  摘要：

  4-烷氧亚氨基嘧啶核苷酸衍生物作为某些G蛋白偶联P2Y受体（P2YRs）的激动剂显示出高度效力。为了对P2Y6R激动剂进行荧光标记，我们在两个位置（胞苷衍生物的N4位和γ-磷酸基团）上探查了包括炔烃在内的各种功能团，用于点击化学反应。在CDP的嘧啶核碱4位上进行扩展亚氨基取代，相比于CTP衍生物中的γ-磷酸酯形成，通常更好地保持了P2Y6R的效力。荧光染料Alexa Fluor 488的共轭物16激活了在1321N1人星形胶质瘤细胞中表达的人P2Y6R，其EC50为9 nM，并且对这种受体的选择性远高于其他由尿嘧啶核苷酸激活的P2Y受体。流式细胞术检测到16对表达P2Y6R的细胞有特异性标记，而对野生型1321N1细胞无标记。此外，共聚焦显微镜显示16被内化（半衰期18分钟）并有表面结合的荧光。已知的P2Y6R配体抑制标记。16与P2Y6R的同源模型的理论对接预测了荧光团与TM3的外部部分之间的静电相互作用。因此，我们确定了N4-苄氧基团作为合成功能化类似物的结构容许位点，从而得到用于研究P2Y6R的高亲和力分子探针。

  We recently reported N4-substituted 3-methylcytidine-5′-α,β-methylenediphosphates as CD73 inhibitors, potentially useful in cancer immunotherapy. We now expand the structure–activity relationship of pyrimidine nucleotides as human CD73 inhibitors. 4-Chloro (MRS4598 16; Ki = 0.673 nM) and 4-iodo (MRS4620 18; Ki = 0.436 nM) substitution of the N4-benzyloxy group decreased Ki by ∼20-fold.

• O-alkylhydroxylamines as rationally-designed mechanism-based inhibitors of indoleamine 2,3-dioxygenase-1

  Indoleamine 2,3-dioxygenase-1 (IDO1) is a promising therapeutic target for the treatment of cancer, chronic viral infections, and other diseases characterized by pathological immune suppression. Recently important advances have been made in understanding IDO1's catalytic mechanism. Although much remains to be discovered, there is strong evidence that the mechanism proceeds through a heme-iron bound alkylperoxy transition or intermediate state. Accordingly, we explored stable structural mimics of the alkylperoxy species and provide evidence that such structures do mimic the alkylperoxy transition or intermediate state. We discovered that O-benzylhydroxylamine, a commercially available compound, is a. potent sub-micromolar inhibitor of IDO1. Structure activity studies of over forty derivatives of O-benzylhydroxylamine led to further improvement in inhibitor potency, particularly with the addition of halogen atoms to the meta position of the aromatic ring. The most potent derivatives and the lead, O-benzylhydroxylamine, have high ligand efficiency values, which are considered an important criterion for successful drug development. Notably, two of the most potent compounds demonstrated nanomolar-level cell-based potency and limited toxicity. The combination of the simplicity of the structures of these compounds and their excellent cellular activity makes them quite attractive for biological exploration of IDO1 function and antitumor therapeutic applications.

  4-Alkyloxyimino derivatives of pyrimidine nucleotides display high potency as agonists of certain G protein-coupled P2Y receptors (P2YRs). In an effort to functionalize a P2Y6R agonist for fluorescent labeling, we probed two positions (N4 and γ-phosphate of cytidine derivatives) with various functional groups, including alkynes for click chemistry. Functionalization of extended imino substituents at the 4 position of the pyrimidine nucleobase of CDP preserved P2Y6R potency generally better than γ-phosphoester formation in CTP derivatives. Fluorescent Alexa Fluor 488 conjugate 16 activated the human P2Y6R expressed in 1321N1 human astrocytoma cells with an EC50 of 9 nM, and exhibited high selectivity for this receptor over other uridine nucleotide-activated P2Y receptors. Flow cytometry detected specific labeling with 16 to P2Y6R-expressing but not to wild-type 1321N1 cells. Additionally, confocal microscopy indicated both internalized 16 (t1/2 of 18 min) and surface-bound fluorescence. Known P2Y6R ligands inhibited labeling. Theoretical docking of 16 to a homology model of the P2Y6R predicted electrostatic interactions between the fluorophore and extracellular portion of TM3. Thus, we have identified the N4-benzyloxy group as a structurally permissive site for synthesis of functionalized congeners leading to high affinity molecular probes for studying the P2Y6R.
