  Antimalarial activity of N6-substituted adenosine derivatives. Part 3

  摘要：

  A series of novel 3'-amido-3'-deoxy-N-6-(l-naphthylmethyl)adenosines was synthesized applying a polymer-assisted solution phase (PASP) protocol and was tested for anti-malarial activity versus the Dd2 strain of Plasm odium falciparum. Further, this series and 62 adenosine derivatives were analyzed regarding 1-deoxy-D-xylulose 5-phospate (DOXP) reductoisomerase inhibition. Biological evaluations revealed that the investigated 3,N-6-disubstituted adenosine derivatives displayed moderate but significant activity against the P. falciparum parasite in the low-micromolar range. On the molecular level, DOXP reductoisomerase utilizing an adenosyl-containing substrate was identified as a promising metabolic target for ligands of adenosine binding motifs. (C) 2003 Elsevier Ltd.

• Orthogonal Activation of the Reengineered A₃ Adenosine Receptor (Neoceptor) Using Tailored Nucleoside Agonists

  An alternative approach to overcome the inherent lack of specificity of conventional agonist therapy can be the reengineering of the GPCRs and their agonists. A reengineered receptor ( neoceptor) could be selectively activated by a modified agonist, but not by the endogenous agonist. Assisted by rhodopsin-based molecular modeling, we pinpointed mutations of the A(3) adenosine receptor (AR) for selective affinity enhancement following complementary modifications of adenosine. Ribose modifications examined included, at 3' : amino, aminomethyl, azido, guanidino, ureido; and at 5' : uronamido, azidodeoxy. N-6-Variations included 3-iodobenzyl, 5-chloro-2-methyloxybenzyl, and methyl. An N-6-3-iodobenzyl-3'-ureido adenosine derivative 10 activated phospholipase C in COS-7 cells (EC50 = 0.18 mu M) or phospholipase D in chick primary cardiomyocytes, both mediated by a mutant ( H272E), but not the wild-type, A(3)AR. The affinity enhancements for 10 and the corresponding 3'-acetamidomethyl analogue 6 were > 100-fold and > 20-fold, respectively. 10 concentration-dependently protected cardiomyocytes transfected with the neoceptor against hypoxia. Unlike 10, adenosine activated the wild-type A(3)AR (EC50 of 1.0 mu M), but had no effect on the H272E mutant A(3)AR (100 mu M). Compound 10 was inactive at human A(1), A(2A), and A(2B)ARs. The orthogonal pair comprising an engineered receptor and a modified agonist should be useful for elucidating signaling pathways and could be therapeutically applied to diseases following organ-targeted delivery of the neoceptor gene.
• SYNTHESIS OF 3′-UREIDOADENOSINE ANALOGUES AND THEIR BINDING AFFINITY TO THE A₃ ADENOSINE RECEPTOR

  Novel 3'-ureidoadenosine analogues were synthesized from 1,2:5,6-di-O-isopropylidene-D-glucose in order to lead to stronger hydrogen bonding at the A(3) adenosine receptor than the corresponding 3'-aminoadenosine derivatives. However, all synthesized 3'-ureidoadenosine analogues have lost their binding affinities to the all subtypes of adenosine receptors, indicating that bulky 3'-urea moiety led to conformational distortion.
