K811 is an ASK1-specific inhibitor that prolongs survival in a mouse model of amyotrophic lateral sclerosis. K811 efficiently prevented cell proliferation in cell lines with high ASK1 expression and in HER2-overexpressing GC cells. Treatment with K811 reduced sizes of xenograft tumors by downregulating proliferation markers.
Pyridoxatin is a fungal metabolite that inhibits production of thiobarbituric acid reactive substance (TBARS). Pyridoxatin inhibits hemolysis induced by the free radical generator AAPH and is active against C. albicans.
AP 811, a selective antagonist of the atrial natriuretic peptide clearance receptor (APN-CR, NPR3) with a K i value of 0.48 nM, exhibits remarkable selectivity for NPR3 over NPR1 by more than 20,000-fold. Moreover, AP 811 effectively eliminates ANP-induced pump stimulation.
