N(G)-Nitro-D-arginine methyl ester (D-NAME) is the less active enantiomer of the nitric oxide (NO) synthase inhibitor N(G)-nitro-L-arginine methyl ester . D-NAME was initially thought to be inactive and was often used as a negative control for L-NAME. Later studies showed that D-NAME (40 mg/kg/day in rats) can have similar but less pronounced effects as L-NAME (40 mg/kg/day in rats) in the cardiovascular system, particularly at long-term timepoints. D-NAME (3-10 µg/mouse) had no effect on nociception in mice assessed using the tail flick test.
PBS-1086 is a novel dual inhibitor of the canonical and noncanonical NF-κB pathways, increasing the magnitude and duration of initial EGFR inhibitor response in multiple NSCLC models, decreasing PDHK1 expression, and suppressing phosphorylation of the PDHK1 protein substrate PDHA1 in a panel of PTEN-deficient cell lines.
