FK506 is a potent immunosuppressive agent which is undergoing clinical testing in liver, kidney, heart, and bone marrow transplantation. It has been shown to effectively prevent and reverse ongoing rejection in these models. From the outset, FK506 was used with low-dose steroids to treat 110 primary liver, 30 heart, and 66 kidney graft recipients. FK506 was also used in the setting of complicat...
In 1987 Ochiai and coworkers presented a report on the immunosuppressive qualities of a new immunosuppressive agent, FK 506, isolated from the fermented broth of a soil fungus, Streptomyces tsukubaensis.1 Extensive in vitro studies demonstrated the effectiveness in suppressing mixed lymphocyte cultures, presumably by inhibiting 1L-2 synthesis following ailoactivation.2 The receptor for FK 506 h...
The carcinogenic potential of oxisuran, a synthetic immunosuppressive agent, was studied for 80 weeks and 104 weeks in mice and rats, respectively. Groups of 50 mice and 70 rats of each sex received oxisuran at doses of 600, 240, and 40 mg/kg/day as dietary admixtures over the entire experimental period. Adequate survival rates allowed accurate statistical analysis of diagnosed neoplasia. Incre...
The first enantioselective synthesis of chiral isosteric phosphonate analogues of FTY720 is described. One of these analogues, FTY720-(E)-vinylphosphonate (S)-5, but not its R enantiomer, elicited a potent antiapoptotic effect in intestinal epithelial cells, suggesting that it exerts its action via the enantioselective activation of a receptor. (S)-5 failed to activate the sphingosine 1-phospha...
Backgrounds/Aims Long-term immunosuppression regimens after liver transplantation (LT) are rarely reported in detail. We aimed to provide information on actual long-term immunosuppression regimens through this cross-sectional study. Methods Our institutional LT database was searched for adult patients who underwent primary LT operation from 2000 to 2016. We identified 3620 live recipients wit...
