Abstract

Abstract POLYPEPTIDES WHICH ARE USEFUL FOR EVALUATING PANCREATIC ENZYME SUFFICIENCY IN ANIMAL ORGANISMS HAVE THE FORMULA RCO-AN-NHR''CO-BM-NHZ WHEREIN R IS A HYDROGEN ATOM; A PHENYL GROUP; A PHENYL GROUP SUBSTITUTED WITH ONE OR MORE HALOGEN ATOMS, (C1-C4) ALKYL GROUPS, HYDROXY GROUPS, (C1-C4)ALKOXY GROUPS, (C1-C2)ALKOXY CARBONYL GROUPS, OR SIMILAR SUBSTITUENTS WHICH WILL NOT INTERFERE WITH THE TEST EFFICACY OF THE POLYPEPTIDE; A (C1-C12)ALKYL GROUP, PREFERABLY A (C1-C6)ALKYL GROUP; A (C1-C12)ALKYL GROUP SUBSTITUTED BY ONE OR MORE HALOGEN ATOMS, (C1-C4)ALKOXY GROUPS, HYDROXY GROUPS, ACYLOXY GROUPS, PREFERABLY (C1-C4) ALKANOYLOXY OR BENZOYLOXY, POLYALKOXYALKYL GROUPS, PHENYL GROUPS, OR SIMILAR SUBSTITUENTS WHICH WILL NOT INTERFERE WITH THE TEST EFFICACY OF THE POLYPEPTIDE; A (C1-C12)ALKOXY GROUP, PREFERABLY A (C1-C6)ALKOXY GROUP; AN ARYLOXY GROUP HAVING UP TO 10 CARBON ATOMS; OR DIVALENT ALKYLENE GROUP HAVING UP TO 6 CARBON ATOMS, IN WHICH CASE THE FORMULA WOULD BE WRITTEN AS R(-CO-AN-NHR''CO-BM-NHZ)2 OR WHEN THE BLOCKING GROUP IS DERIVED FROM OXALIC ACID, AS (CO-AN-NHR''CO-BM-NHZ)2 NHR''CO IS THE AMINO ACID LINKAGE DERIVED FROM L-PHENYLALANINE, L-TYPROSINE, L-LEUCINE, L-METHIONINE, L-TRYPTOPHAN, L-ARGININE, OR L-LYSINE; Z IS A GROUP OF THE FORMULA (R"-Y-),(X)N''-PHENYL WHEREIN R'''' IS A HYDROXY GROUP, A (C1-C4)ALKOXY GROUP, A (C1-C4) ALKOXYALKOXY GROUP, A (C1-C8)AMINOALKOXY GROUP, AN AMINO GROUP, A (C1-C4)MONOALKYLAAMINO GROUP, A (C1-C4)DIALKYLAMINO GROUP, A GROUP OF THE FORMULA NHCH2COR'''', OR A SALT, SUCH AS THE SODIUM, POTASSIUM, OR AMMONIUM SALT, OF THE GROUP IN WHICH R'''' IS A HYDROXY GROUP; Y IS A GROUP OF THE FORMULA -CO-OR-SP2-; X IS A HYDROXY GROUP, A (C1-C4)ALKYL GROUP, A HALOGEN ATOM, A (C1-C4)ALKOXY GROUP, OR A SIMILAR SUBSTITUENT WHICH WILL NOT INTERFERE WITH THE TEST EFFICACY OF THE POLYPEPTIDE; AND N'' IS 0, 1, OR 2; A AND B ARE THE RESIDUES OF LOW MILECULAR WEIGHT AMINO ACIDS, SUCH AS GLYCYL, ALANYL, GLYCYLGLYCYL, AND THE LIKE, AND N AND M ARE 0, 1, OR 2.
