Three oxazole analogues of the insect neuropeptide proctolin (H-Arg-Tyr-Leu
-Pro-Thr-OH) have been prepared, containing a single oxazole between Tyr an
d Pro and between Pro and Thr, respectively. A compound containing an oxazo
le moiety between Tyr and Pro and between Pro and Thr has also been prepare
d. All compounds have been tested for myotropic activity.
