More Info
Biological target:
CTPI-2 is a third-generation mitochondrial citrate carrier SLC25A1 inhibitor with a KD of 3.5 μM. CTPI-2 inhibits glycolysis, PPARγ, and its downstream target the glucose transporter GLUT4.
In vitro activity:
CTPI-2 inhibited mitochondrial respiration of CSCs spheres (Fig. 4c) and effectively inhibited their self-renewal again showing lesser anti-proliferative activity in 2D cultures (Figs. 5a–c). Reference: Cell Death Differ. 2018 Jul;25(7):1239-1258. https://pubmed.ncbi.nlm.nih.gov/29651165/
In vivo activity:
This study next studied the effects of CTPI-2 in the liver of HFD-fed mice. In mice fed with the HFD the liver was filled with fatty deposits that accumulated over time in the form of micro- and macrovesicular steatosis, and the hepatocytes exhibited typical ballooning degeneration, indicating the presence of steatohepatitis (Fig. 2a). Accordingly, these mice displayed hypercholesterolemia and hepatic injury as demonstrated by the elevated levels of Alanine Aminotransferase (ALT) and CTPI-2 normalized cholesterol, ALT and triglyceride levels (Fig. 2b–d). After 3 months of exposure to the HFD, at which time CTPI-2 treatment started, steatosis was already evident and progressed over time. CTPI-2 reverted these early stages of steatosis and also prevented the evolution to steatohepatitis, identified based upon the dramatic increase of lipid accumulation, the presence of hepatocyte ballooning (Fig. 2a), the elevated levels of ALT (Fig. 2c) and the presence of perivascular inflammatory infiltration (not shown).
