pkm2-in-1

PKM2-IN-1 (compound 3k) exhibits inhibitory activity against PKM2 with an IC50 of 2.95 μM, while the IC50 for PKM1 is 4-5 times higher.

PKM2 PDK1-IN-1, a shikonin thioether derivative, serves as a dual inhibitor for PKM2 PDK1. This compound effectively inhibits the proliferation and induces apoptosis in NSCLC cells. It promotes intercellular ROS production and modulates apoptotic proteins, engaging in both mitochondrial and death receptor pathways [1].

Mitapivat (PKR-IN-1), also known as PKM2 activator 1020 is a PKM2 activator (pyruvate kinase activator) for the treatment of pyruvate kinase deficiency.

PKM2 modulator 1 (compound C998) is an effective PKM2 inhibitor with antiproliferative activity. It induces apoptosis and holds potential for research in glioblastoma studies.

PKM2 Activator 4, a chemical compound, functions as an activator of PKM2 with an activation concentration (AC 50) ranging from 1 to 10 μM. It is primarily utilized in cancer research.

Vitamin K5 (Synkamin), a photosensitizer and antimicrobial agent, serves as a specific PKM2 inhibitor, demonstrating IC 50 values of 28, 191, and 120 μM against PKM2, PKM1, and PKL, respectively. It induces apoptosis in colon 26 cells and is utilized in infection and cancer research. Additionally, Vitamin K5 finds application as a preservative in pharmaceuticals, foods, and beverages [1] [2] [3].

MTP, a PKM2 inhibitor, promotes apoptosis in cancer cells via caspase-3 activation while also inducing autophagy and enhancing ROS generation. Further, it inhibits JAK2 signaling, rendering it useful for the study of oral squamous cell carcinoma [1].

Compound 5C, referred to as Pkm2-in-4, is a selective PKM2 inhibitor (IC50 = 0.35 µM) that modulates pyruvate-dependent respiration and promotes mitochondrial H2O2 production rate and electron transport system coupling [1].

CIAC001, a pyruvate kinase PKM2 inhibitor, exhibits anti-neuroinflammatory properties. It effectively suppresses LPS-induced production of proinflammatory nitric oxide (NO) and provides protection to immunologically active BV-2 cells with an IC50 value of 2.5 μM. Additionally, CIAC001 demonstrates anti-neuroinflammation effects in mouse models and attenuates chronic morphine-induced addiction [1].

Compound Z10 (PKM2 activator 6) serves as both a PKM2 activator and a PDK1 inhibitor, exhibiting dissociation constants (K D ) of 121 μM and 19.6 μM, respectively. It promotes apoptosis in colorectal cells while suppressing their proliferation and migration, additionally inhibiting glycolysis. Compound Z10 demonstrates inhibitory effects on the proliferation of various cell lines, including DLD-1, HCT-8, HT-29, and MCF-10A, with half-maximal inhibitory concentrations (IC 50 ) of 10.04 μM, 2.16 μM, 3.57 μM, and 66.39 μM, as recorded in reference [1].

NPD10084 is an inhibitor of pyruvate kinase PKM2 that blocks non-glycolytic signaling in cancer cells by disrupting PKM2's interaction with β-catenin or STAT3, thus inhibiting downstream pathways. It demonstrates antiproliferative effects against colorectal cancer cells both in vitro and in vivo [1].

PKM2-IN-6 (compound 7d) is a potent PKM2 inhibitor that can be administered orally and demonstrates an IC 50 value of 23 nM. It triggers apoptosis and causes cell cycle arrest in the G2 phase, while also reducing the mRNA levels of both PKM1 and PKM2. Additionally, PKM2-IN-6 exhibits anticancer properties and shows promise for research in triple-negative breast cancer [1].
