Abstract:
:The synthesis and receptor binding of novel adenosine receptor antagonists is described. We found that non-xanthine 4-phenyl-2-(phenylcarboxamido)-1,3-thiazole derivatives may have high affinity and substantial selectivity for the adenosine A(1) receptor.

杂志文章abstract::Photocleavable linkers are advantageous over the common linkers because they could be cleaved without using reagents. A novel photocleavable linker with an α-thioacetophenone moiety has been developed. This linker, which can be cleaved upon irradiation at 365 nm via the Norrish type II reaction, is applicable to a pro...
