kl1333

KL1333 (NQO1 activator 1) enhances energy metabolism and mitochondrial dysfunction in MELAS fibroblasts. Elevated NAD+ levels trigger the activation of SIRT1 and AMPK, and subsequently activates PGC-1α. NQO1 activator 1 is an orally available NAD+ modulator. It reacts with NAD(P)H: NQO1 as a substrate, resulting in increases in intracellular NAD+ levels via NADH oxidation.

KL1333 hydrochloride is an orally effective NAD+ modulator that acts as a substrate for NAD(P)H: quinone oxidoreductase 1 (NQO1), leading to increased intracellular NAD+ levels through NADH oxidation. Elevated NAD+ subsequently activates SIRT1 and AMPK, which in turn activate PGC-1α. KL1333 hydrochloride improves energy metabolism and mitochondrial dysfunction in fibroblasts of mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS). It also has a protective effect against cisplatin-induced ototoxicity in cultured mouse cochlea.
