Biochem/physiol Actions

CTPI-2 is a selective mitochondrial citrate transporter (SLC25A1) inhibitor that displays H1299 anti-proliferation activity in a SLC25A1-dependent manner (IC50 <10  μM). When compared with CTPI-1, CTPI-2 exhibits 20-fold higher target affinity (hSLC25A1 KD = 3.5 μM vs. 63.6 μM, respectively) and is ~1000-fold more potent against H1299 sphere-forming capacity. CTPI-2 inhibits mitochondrial respiration and formation of patient NSCLC tumors-derived CSCs spheres in cultures (10-50 μM), as well as suppresses the growth of patent-derived NSCLC exnografts in mice in vivo (28 mg/kg q.o.d. i.p.).

Therapy resistance represents a clinical challenge for advanced non-small cell lung cancer (NSCLC), which still remains an incurable disease. There is growing evidence that cancer-initiating or cancer stem cells (CSCs) provide a reservoir of slow-growing dormant populations of cells with

Oncogenic mutations in metabolic genes and associated oncometabolite accumulation support cancer progression but can also restrict cellular functions needed to cope with DNA damage. For example, gain-of-function mutations in isocitrate dehydrogenase (IDH) and the resulting accumulation of the oncometabolite D-2-hydroxyglutarate
