  Syntheses and Calcium-Mobilizing Evaluations of N-Glycosyl-Substituted Stable Mimics of Cyclic ADP-Ribose

  摘要：

  Cyclic ADP-ribose (cADPR) is not only a potent endogenous calcium modulator but also a second messenger. However, studies on the mechanism of cADPR action were limited due to its instability and lack of available structural modifications in the N-1-glyosyl unit of cADPR. In the present work, a series of N-1-glycosyl mimics with different configurational glycosyls or an ether strand were designed and synthesized mimicking the furanose ring. S(N)2 substitutions were carried out between the protected inosine and glycosyl triflates to form the N-1-glycosylinosine derivatives, accompanied with some O-6-glyeosyl-substituted as side products. The intramolecular cyclization was followed the strategy described by Matsuda et al. It was found that the 8-unsubstituted substrate could also be used to construct the intramolecular cyclic pyrophosphate. The activities of NI-glycosyl-substituted cADPR mimics were evaluated by induced Ca2+ release in rat brain microsomes and HeLa cells. It was found that the configuration of the N-1-glycosyl moiety in cADPR is not a critical structural factor for retaining the activity of mobilizing Ca2+ release. More interestingly, the N-1-acyclic analogue 6 exhibited strong activity by inducing Ca2+ release in both rat brain microsomes and HeLa cells. It constitutes a useful tool for further studies.

  Nucleosides and Nucleotides. 173. Synthesis of Cyclic IDP-carbocyclic-ribose, a Stable Mimic of Cyclic ADP-ribose. Significant Facilitation of the Intramolecular Condensation Reaction of N-1-(Carbocyclic-ribosyl)inosine 5‘,6‘‘-Diphosphate Derivatives by an 8-Bromo-Substitution at the Hypoxanthine Moiety

  摘要：

  Cyclic ADP-ribose (cADPR, 1) is a general mediator involved in cellular Ca2+ signaling. However, both the biological and chemical instability of cADPR limit studies on its physiological role. We designed cyclic ADP-carbocyclic-ribose (3) and its inosine congener 4 as stable mimics of cADPR and successfully synthesized 4. Starting with cyclopentadiene, the optically active carbocyclic unit 8 was constructed via enzymatic optical resolution. S(N)2 reactions of 8 with inosine derivative 7 and the 8-bromoinosine derivative 25 gave the N-1-substituted derivatives 6 and 26, which were converted to the corresponding diphosphate derivatives 5 and 22. The intramolecular condensation reactions between the two phosphate groups of 5 and 22 were investigated, Although the reaction with inosine derivative 5 did not produce any of the cyclization product 20, treatment of the corresponding 8-bromoinosine derivative 22 with EDC gave the desired intramolecular condensation product 29 in 23% yield. Thus, the significant effect of the 8-bromo group at the hypoxanthine moiety in facilitating the key intramolecular condensation reaction between the phosphate groups of the substrate 22 was recognized. This is possibly due to conformational restriction of the molecule in a syn-form around its glycosyl linkage. The 8-bromo and isopropylidene groups were removed in succession to give the target compound 4. This is the first total synthesis of this type of cyclic nucleotide.

  A convenient trifluoromethylation method was firstly applied to the synthesis of 8- CF3-purine nucleosides. On the basis of this method, new protection and deprotection strategies were developed for the successful synthesis of the trifluoromethylated cyclic-ADP-ribose mimic, 8-CF3-cIDPRE 1. Using intact, fura-2-loaded Jurkat T cells compound 1 and 2′,3′-O-isopropylidene 8-CF3-cIDPRE 14 were characterized as membrane-permeant cADPR agonists. Contrary to the 8-substituted cADPR analogues that mainly act as antagonists of cADPR in cells, 8-substituted cIDPRE derivatives were shown to be Ca2+ mobilizing agonists. Here we report that even compound 1, the 8-substituted cIDPRE with the strong electron withdrawing CF3 group, behaves as an agonist in T cells. Interestingly, also the partially protected 2′,3′-O-isopropylidene 8-CF3-cIDPRE activated Ca2+ signaling indicating only a minor role for the hydroxyl groups of the southern ribose of cADPR for its biological activity. To our knowledge 8-CF3-cIDPRE 1 is the first reported fluoro substituted cADPR mimic and 8-CF3-cIDPRE 1 and compound 14 are promising molecular probes for elucidating the mode of action of cADPR.

  To study the properties of hydrolysates of cyclic adenosine diphosphate ribose (cADPR), a series of novel acyclic analogues of cADPR with an ether chain as the northern moiety and 8-substituted adenine or hypoxanthine as the base moiety were synthesized via an N1 substitution construction, followed by bisphosphorylation, phosphoramidition or pyrophosphorylation. These compounds also provide various precursors for synthesizing cADPR analogues.

  An efficient synthesis of cyclic IDP-carbocyclic-ribose, as a stable mimic for cyclic ADP-ribose, was achieved. N-1-Carbocyclic-ribosylinosine derivative 15, prepared from N-1-(2,4-dinitrophenyl)inosine derivative 10 and an optically active carbocyclic amine 11, was converted to 8-bromo-N-1-carbocyclic-ribosylinosine bis-phosphate derivative 20. Treatment of 20 with I-2 in the presence of molecular sieves in pyridine gave the desired cyclic product 8 quantitatively, which was deprotected and reductively debrominated to give the target cyclic IDP-carbocyclic ribose (3).
