SYNTHESIS AND BIOLOGICAL PROPERTIES OF CHOLECYSTOKININ HEPTAPEPTIDE ANALOGUES CONTAINING D- AND L-FORMS OF TERT-LEUCINE OR NEOPENTYLGLYCINE IN POSITION 5

Using solution or solid-phase synthesis we prepared the cholecystokinin fragment Boc-CCK-7 (Boc-Tyr-(SO3-*Na+)-Met-Gly-Trp-Met-Asp-PheNH2) and its four analogues in which the methionine moiety (Met) in the carboxy-terminal part is re
