Design and evaluation of xanthine based adenosine receptor antagonists: Potential hypoxia targeted immunotherapies
摘要:
Molecular modeling techniques were applied to the design, synthesis and optimization of a new series of xanthine based adenosine A(2A) receptor antagonists. The optimized lead compound was converted to a PEG derivative and a functional in vitro bioassay used to confirm efficacy. Additionally, the PEGylated version showed enhanced aqueous solubility and was inert to photoisomerization, a known limitation of existing antagonists of this class. (C) 2013 Elsevier Ltd.
