摘要:
Based on the examination of the X-ray crystallographic structures of the LBD of TR alpha and TR beta in complex with KB-141 (2), a number of novel 4'-hydroxy bioisosteric thyromimetics were prepared. Optimal affinity and P-selectivity (33 times), was found with a medium-sized alkyl-substituted amido group; iso-butyl (12c). It can be concluded that bioisosteric replacements of the 4'-hydroxy position represent a new promising class of TR beta-selective synthetic thyromimetics. (c) 2005 Published by Elsevier Ltd.
