  8-Bromo-9-alkyl adenine derivatives as tools for developing new adenosine A2A and A2B receptors ligands

  摘要：

  Importance of making available selective adenosine receptor antagonists is boosted by recent findings of adenosine involvement in many CNS dysfunctions. In the present work a series of 8-bromo-9-alkyl adenines are prepared and fully characterized in radioligand binding assays or functional cyclase experiments in respect to their interaction with all the four adenosine receptor subtypes. Results show that the presence of the bromine atom in 8-position of 9-substituted adenines promotes in general the interaction with the adenosine receptors, in particular at the A(2A) subtype. The present study also demonstrates that adenine derivatives could be a good starting point to obtain selective adenosine A(2B) receptor antagonists. (c) 2009 Elsevier Ltd. All rights reserved.

  A new 9-alkyladenine-cyclic methylglyoxal diadduct activates wt- and F508del-cystic fibrosis transmembrane conductance regulator (CFTR) in vitro and in vivo

  摘要：

  Cystic fibrosis transmembrane conductance regulator (CFTR) is the main chloride channel present in the apical membrane of epithelial cells and the F508 deletion (F508del-CFTR) in the CF gene is the most common cystic fibrosis-causing mutation. In the search for a pharmacotherapy of cystic fibrosis caused by the F508del-CFTR, a bi-therapy could be developed associating a corrector of F508del-CFTR trafficking and an activator of the channel activity of CFTR. Here, we report on the synthesis of 9-alkyladenine derivatives analogues of our previously discovered activator of wt-CFTR and F508del-CFTR, GPact-11a, and the identification of a new activator of these channels, GPact-26a, through various flux assays on human airway epithelial CF and non-CF cell lines and in vivo measurement of rat salivary secretion. This study reveals that the possible modifications of the side chain introduced at the N9 position of the main pharmacophore are highly limited since only an allyl group can replace the propyl side chain present in GPact-11a to lead to a strong activation of wt-CFTR in CHO cells. Docking simulations of the synthesised compounds and of four described modulators performed using a 3D model of the wt-type CFTR protein suggest five possible binding sites located at the interface of the nucleotide binding domains NBD1/NBD2. However, the docking study did not allow the differentiation between active and non-active compounds.

  Highly efficient protocol for one-pot N-alkylation of nucleobases using alcohol in ionic liquid media as a straightforward route to access acyclic nucleoside was described. In this protocol purine, pyrimidine as well as azole derivatives underwent the N-alkylation reaction with primary or secondary alcohols using TsCl/TEA/K2CO3 in bmim[Br] to afford the products in good-to-excellent yields. The influence of factors in this method including the type of ionic liquid, base and sulfonating agents was discussed. The current method showed an appropriate selectivity in reaction with primary alcohols in comparison with secondary alcohols. This protocol is mild, safe and easy to apply; moreover, it is quite compatible with eco-friendly and green chemistry protocols, since the exploitation of toxic and hazardous materials such as DMF and alkyl halides has been prevented.
