Benzotript

Benzotript (INNTooltip International Nonproprietary Name), also known as N-(p-chlorobenzoyl)-L-tryptophan, is a muscle relaxant that inhibits gastric secretion and was never marketed.^[1][2] It is a tryptamine derivative and the N-(4-chlorobenzoyl) analogue of the amino acid tryptophan.^[1] Similarly to proglumide (N²-benzoyl-N,N-dipropyl-α-glutamine), the drug acts as a competitive and non-selective cholecystokinin receptor antagonist.^[2][3] Other more potent tryptophan derivatives have also been developed as cholecystokinin (CCK) antagonists.^[2]
