The ability to synthesize new molecular structures can greatly augment
investigations of cellular systems. Synthetic chemistry coupled with
structure determination is an especially powerful combination. These t
echniques have played a vital role in both the discovery and character
ization of a family of intracellular receptors known as immunophilins.
This review will attempt to highlight the synthetic and structural st
udies of immunophilin receptors that have been carried out in the Harv
ard and Cornell laboratories during the past several years.
