acid side chains in place of glutamate were synthesized and tested as inhibitors of folylpolyglutamate synthetase (FPGS) frommouseliver. The aminophosphonoalkanoic acid analogues were also tested as inhibitors of dihydrofolate reductase (DHFR) fromL1210 murine leukemia cells and as inhibitors of the growth of MTX-sensitive (L1210) and MTX-resistant (L1210/R81) cells in culture. The optimal number

the omega-guanidinoalkanesulfonic acids. Most of the omega-aminoalkanesulfonic acids have antifibrinolyticactivity, while none of the omega-guanidinoalkanesulfonic acids has significant antifibrinolyticactivity. Compound 4 possessed the highest antifibrinolyticactivity which was equal to or greater than that of epsilon-aminohexanoic acid.
membrane. Herein, to balancepotency and physicochemicalproperties, a series of gut-restrictedTGR5agonists with diversified kinetophores had been designed and synthesized. Compound 22-Na exhibited significant antidiabetic effect, and showed favorable gallbladder safety after 7 days of oral administration in humanized TGR5H88Y mice, confirming that gut-restricted agonism of TGR5 is a viable strategy
