 Use of CTPI-2


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[1][2].

In Vivo CTPI-2 is a unique regulator of glycolysis that limits the metabolic plasticity of cancer stem cells (CSCs). CTPI-2 (26 mg/kg; i.p.) inhibits tumor growth in in vivo models of non-small cell lung cancer (NSCLC)[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]. Animal Model: C57BL/6J mice (HFD-fed mice)[2] Dosage: 50 mg/kg Administration: Alternate days via the intraperitoneal route for 12 weeks Result: Completely averted weight gain in the prevention study and led to significant weight loss in the reversion study.
