Design, synthesis and initial biological evaluation of a novel pladienolide analog scaffold.

abstract：:Recognition of nucleosides at adenosine receptors (ARs) is supported by multiple X-ray structures, but the structure of an adenine complex is unknown. We examined the selectivity of predicted A1AR and A3AR adenine antagonists that incorporated known agonist affinity-enhancing N6 and C2 substituents. Adenines with A1AR...
