CTPI-2
Based on 14 publication(s) in Google Scholar
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. CTPI-2 halts salient alterations of NASH reverting steatosis, preventing the evolution to steatohepatitis, reducing inflammatory macrophage infiltration in the liver and adipose tissue, and starkly mitigating obesity induced by a high-fat diet. Antitumor activity.

Biological Activity
KD: 3.5 μM (SLC25A1)[1]
CTPI-2 (50 mg/kg; i.p.; alternate days for 12 weeks) completely averts weight gain in the prevention study and leads to significant weight loss in the reversion study[2].
CTPI-2 prevents steatohepatitis and normalizes glucose tolerance. CTPI-2 lowers the levels of circulating IL-6 while increasing anti-inflammatory IL-4 and IL-10 and also reduced the monocyte chemoattractant protein-1 and monokine-induced by interferon-γ that attract neutrophils and monocytes. CTPI-2 regulates the citrate pool, the lipogenic and the gluconeogenic pathways[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
