Bentiromide is a peptide used as a screening test for exocrine pancreatic insufficiency and to monitor the adequacy of supplemental pancreatic therapy. It is given by mouth as a noninvasive test. The amount of 4-aminobenzoic acid and its metabolites excreted in the urine is taken as a measure of the chymotrypsin-secreting activity of the pancreas. Headache and gastrointestinal disturbances have been reported in patients taking bentiromide. Bentiromide is not available in the United States or Canada (it was withdrawn in the U.S. in October 1996.)
Synthetic chymotrypsin-labile peptide, used in diagnosis of exocrine pancreatic disease.
It is synthesized by amide formation between ethyl p-aminobenzoate and N-benzoyl-tyrosine using N-methyl-morpholine and ethyl chlorocarbonate for activation. The resulting L-amide is selectively hydrolyzed by sequential use of dimsyl sodium (NaDMSO) and dilute acid to give bentiromide (4).
