pkm-2-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-IN-10 is a PKM2 inhibitor. It effectively suppresses the proliferation of A549 and HCC1833 cell lines with IC50 values of 3.36 μM and 9.20 μM, respectively. PKM2-IN-10 demonstrates antitumor activity in human non-small cell lung cancer (NSCLC) and mouse lung adenocarcinoma models. It is applicable for research in lung cancer.

PKM2-IN-11 is a PKM2 inhibitor with an IC50 value of 0.363 μM. It operates through dual mechanisms, inhibiting pyruvate kinase M2 (PKM2) and stabilizing microtubules. This compound reduces PKM2 protein levels in MCF-7 cells, slightly decreases reactive oxygen species (ROS) levels, and significantly increases early apoptosis in cells. Additionally, PKM2-IN-11 induces G2/M phase arrest and is applicable in breast cancer research.

PKM2-IN-12 is an orally active PKM2 inhibitor with an IC50 of 10 nM. It effectively hinders the proliferation and migration of COLO-205 cells, induces cell cycle arrest, and triggers apoptosis (apoptosis). PKM2-IN-12 significantly reduces lactate, pyruvate, and ROS levels in cells. In mouse models, it not only directly targets cancer cells but also restores disrupted intestinal microecological balance. PKM2-IN-12 is useful for colorectal cancer research.

PKM2-IN-13 is a selective inhibitor of PKM2 with an IC50 value of 55.13 μM. This compound demonstrates broad-spectrum anticancer activity while exhibiting low toxicity to normal cells. PKM2-IN-13 induces apoptosis by elevating reactive oxygen species (ROS) levels and activating Caspase-3/7. It interacts with pyruvate kinase M2 in vitro, inhibiting its glycolytic function. Additionally, PKM2-IN-13 has shown a good safety profile, with no significant adverse effects observed in in vivo experiments. It can be utilized in research studies involving oral squamous cell carcinoma, colon cancer, breast cancer, and melanoma.
