Description |
TM5441 is a plasminogen activator inhibitor-1 (PAI-1); inhibits several tumor cell lines with IC50 values between 9.7 and 60.3 μM.

In Vitro |
TM5441 dose-dependently decreases HT1080, HCT116, Daoy, MDA-MB-231 and Jurkat cells with an IC50 ranging between 9.7 and 60.3 μM. TM5441 decreases tumor cell viability in part through diminished proliferation. TM5441 increases caspase 3/7 activity for both HT1080 and HCT116 cells in a dose dependant manner. TM5441is a potent stimulators of intrinsic apoptosis in tumor cells. TM5441 induces mitochondrial depolarization[1]. In mouse proximal tubular epithelial cells, TM5441 effectively inhibits PAI-1-induced mRNA expression of fibrosis and inflammation markers and also reverses PAI-1-induced inhibition of plasmin activity[2].

In Vivo |
Oral administration of TM5441 (20 mg/kg daily) to HT1080 and HCT116 xenotransplanted mice increases tumor cell apoptosis and has a significant disruptive effect on the tumor vasculature that is associated with a decrease in tumor growth and an increase in survival. The average peak plasma concentration is 11.4 μM one hour after oral administration and undetectable levels 23 hours after administration[1]. TM5441 effectively inhibits albuminuria, mesangial expansion, ECM accumulation, and macrophage infiltration in diabetic kidneys[2].

Cell Assay |
HT1080, HCT116, Daoy, MDA-MB-231 and Jurkat cells are treated with 0-100 μM TM5441 for 48 hours at 37°C. Cell viability is measured by MTT assay[1].
|
Animal Admin |
Mice: TM5275 at 50 mg/kg/day and TM5441 at 10 mg/kg/day were orally administered in control and diabetic mice for 16 weeks. Mice were monitored at least once a day. At the end, blood is collected for measurement of plasma glucose and creatinine, urine for protein measurement, and kidneys for immunohistochemical analysis[2].
