Ketomethylene pseudopeptide analogs of substance P: synthesis and biological activity
characterized, and tested for their biological activity and inhibitory effect on SP degrading enzymes. Analogue II was a full agonist contracting the isolated guineapigileum with a potency of 70% compared to the parent hexapeptide [pGlu6]SP6-11. It was also a potent inhibitor of SP degrading activity in rat diencephalon membranes with a Ki of 20 microM whereas analogue I was a weak inhibitor.
Compounds being analogues of a dipeptide in which the nitrogen atom of the linking amide group of the dipeptide is replaced by trivalent group ##STR1## and in which, optionally, the carbonyl function of this linking group is replaced by the divalent group --CH.sub.2 -- are of value in the synthesis of isosterically modified peptides.
