Abstract
|
|
|
The crystal structure of a complex of the catalytic subunit (type alpha) of
cAMP-dependent protein kinase (PKA C alpha) with ARC-type inhibitor (ARC-1034),
the presumed lead scaffold of previously reported adenosine-oligo-arginine
conjugate-based (ARC-type) inhibitors, was solved. Structural elements important
for interaction with the kinase were established with specifically modified
derivatives of the lead compound. On the basis of this knowledge, a new
generation of inhibitors, conjugates of
adenosine-4'-dehydroxymethyl-4'-carboxylic acid moiety and oligo(D-arginine),
was developed with inhibitory constants well into the subnanomolar range. The
structural determinants of selectivity of the new compounds were established in
assays with ROCK-II and PKBgamma.
