title: Inhibition of glucose absorption by 3-phenylpropylaminoguanidine-HCl (SaH 43-522) in laboratory animals.
abstract: The present studies were undertaken to define the effects of 3-phenylpropylaminoguanidine-HCl (SaH 43-522 or 43-522) on glucose active transport in the gastrointestinal tract. A comparison with phenformin (DBI) was made in certain studies. SaH 43-522 is 2 to 3 times more potent than DBI with regard to its inhibitory effect on glucose active transport in the gastrointestinal tract of rats. The activity lasts for 5 hr after oral administration. SaH 43-522 also inhibits intestinal glucose absorption in the hamster, guinea-pig, dog, and monkey in either in vitro or in vivo systems. SaH 43-522 differs from DBI in that when glucose active transport is studied in vitro by adding drug into the incubation fluid, DBI is active only when the drug is present in the incubation fluids on both the mucosal and serosal sides, whereas SaH 43-522 is active in inhibiting intestinal glucose active transport when the drug is present in mucosal fluid only.
