  Synthesis, Bioactivation and Anti-HIV Activity of 4-Acyloxybenzylbis(Nucleosid-5′-yl) Phosphates

  摘要：

  4-Acyloxybenzyl bis(nucleosid-5'-yl) phosphates 7a-c and 9a-c were prepared as potential prodrugs of the anti-HIV nucleosides 3'-azido-3'-deoxythymidine (AZT) and 2',3'-dideoxyinosine (ddI) or their 5'-monophosphates.The anti-HIV activities of these triesters were determined in two T-cell lines. In a C8165 cell line they displayed activities comparable to and in some cases superior to AZT, but they also exhibited an increase in cytotoxicity. In a thymidine kinase deficient JM T-cell line the activity was reduced but was still superior to AZT. In the presence of porcine liver carboxyesterase (PLCE), triester 7b biodegrades to the diester 10 which, with phosphodiesterase, gives initially AZT monophosphate 3 and AZT.

  Formulating a new basis for the treatment against botulinum neurotoxin intoxication: 3,4-Diaminopyridine prodrug design and characterization

  摘要：

  Botulism is a disease characterized by neuromuscular paralysis and is produced from botulinum neurotoxins (BoNTs) found within the Gram positive bacterium Clostridium botulinum. This bacteria produces the most deadliest toxin known, with lethal doses as low as 1 ng/kg. Due to the relative ease of production and transport, the use of these agents as potential bioterrorist weapons has become of utmost concern. No small molecule therapies against BoNT intoxication have been approved to date. However, 3,4-diaminopyridine (3,4-DAP), a potent reversible inhibitor of voltage-gated potassium channels, is an effective cholinergic agonist used in the treatment of neuromuscular degenerative disorders that require cholinergic enhancement. 3,4-DAP has also been shown to facilitate recovery of neuromuscular action potential post botulinum intoxication by blocking K(+) channels. Unfortunately, 3,4-DAP displays toxicity largely due to blood-brain-barrier (BBB) penetration. As a dual-action prodrug approach to cholinergic enhancement we have designed carbamate and amide conjugates of 3,4-DAP. The carbamate prodrug is intended to be a slowly reversible inhibitor of acetylcholinesterase (AChE) along the lines of the stigmines thereby allowing increased persistence of released acetylcholine within the synaptic cleft. As a secondary activity, cleavage of the carbamate prodrug by AChE will afford the localized release of 3,4-DAP, which in turn, will enhance the pre-synaptic release of additional acetylcholine. Being a competitive inhibitor with respect to acetylcholine, the activity of the prodrug will be greatest at the synaptic junctions most depleted of acetylcholine. Here we report upon the synthesis and biochemical characterization of three new classes of prodrugs intended to limit previously reported stability and toxicity issues. Of the prodrugs examined, compound 32, demonstrated the most clinically relevant half-life of 2.76 h, while selectively inhibiting AChE over butyrylcholinesterase-a plasma-based high activity esterase. Future in vivo studies could provide validation of prodrug 32 as a potential treatment against BoNT intoxication as well as other neuromuscular disorders. (C) 2011 Elsevier Ltd. All rights reserved.

  We disclose a study on nucleoside triphosphate (NTP) analogues in which the γ-phosphate is covalently modified by two different biodegradable masking units and d4T as nucleoside analogue that enable the delivery of d4TTP with high selectivity in phosphate buffer (pH 7.3) and by enzyme-triggered reactions in human CD4+ T-lymphocyte CEM cell extracts. This allows the bypass of all steps normally needed

  我们公开了一项关于核苷三磷酸酯（NTP）类似物的研究，其中γ-磷酸酯被两个不同的可生物降解的掩蔽单元和d4T进行了共价修饰，从而使d4TTP在磷酸盐缓冲液（pH 7.3）和酶中具有较高的选择性CD4 + T淋巴细胞CEM细胞提取物中触发的反应。这允许绕过细胞内磷酸化通常所需的所有步骤。这些Tri PPP将包含酰氧基苄基（AB；酯）或烷氧基羰氧基苄基（ACB；碳酸酯）与ACB部分结合的环核苷酸描述为NTP递送系统。这两个不同基团的引入导致通过化学水解，特别是通过细胞提取酶选择性地形成γ-（ACB）-d4TTP。γ-（AB）-d4TTP的裂解速度比γ-（ACB）-d4TTP更快。在抗病毒测定中，这些化合物在野生型CEM / O细胞中具有更强的抗HIV-1和HIV-2活性，更重要的是在缺乏胸苷激酶的CD4 + T细胞（CEM / TK –）中具有很高的活性。

• Design and synthesis of an ER-specific fluorescent probe based on carboxylesterase activity with quinone methide cleavage process

  CEs are important enzymes that catalyze the hydrolysis of prodrugs. In this Letter, we present a new mechanistic ER-specific fluorescent probe 1 based on CE activity. Permeation of 1 into cells and subsequent hydrolytic activation by CEs causes spontaneously quinone methide cleavage, resulting in bright red fluorescence in ER with high specificity. Probe 1 was developed for CE activity imaging and inhibitor screening at the cellular level. (C) 2011 Elsevier Ltd. All rights reserved.
• Multicolor Imaging of Endoplasmic Reticulum-Located Esterase As a Prodrug Activation Enzyme

  The carboxylesterase families of enzymes are key participants in phase I drug metabolism processes. Carboxylesterase families I and 2 are of particular clinical relevance. These enzymes produce endoplasmic reticulum localization signals, are primarily localized in the endoplasmic reticulum, and hydrolyze a wide range of ester-containing prodrugs into an activated form. In order to detect enzymes belonging to both families, we developed an optical multicolor imaging technique, which provides a distinct color window for multicolor imaging. This technique required the design and synthesis of three new mechanistic colored probes that fluoresce red, green, or blue and are based on the quinone methide cleavage process. These activity-based probes allow rapid and clear visualization with high specificity against the endoplasmic reticulum in cultured cells based on endoplasmic reticulum localized esterases including both families of carboxylesterase enzymes.
