PTP1B-IN-22 is a protein tyrosine phosphatase 1B (PTP1B) inhibitor that inhibits glucose uptake in skeletal muscle L6 myotubes.

Beauverolide Ka, a cyclotetradepsipeptide derived from the Beauveria bassiana fungus, enhances glucose absorption in rat L6 myoblasts cultured at a concentration of 50 μM and exhibits protective effects on HEI-OC1 cells at 10 μM. It demonstrates dose-dependent activities in both L6 myoblasts and myotubes [1] [2].

Galegine hydrochloride, a guanidine derivative derived from G. officinalis, plays a role in inducing weight loss in mice and has contributed to the development of biguanides, including metformin and phenformin. This compound stimulates AMPK activation in 3T3-L1 adipocytes, L6 myotubes, H4IIE rat hepatoma, and HEK293 human kidney cell lines. Additionally, galegine hydrochloride exhibits antibacterial properties, particularly demonstrating a minimum inhibitory concentration of 4 mg/L against Staphylococcus aureus strains[1][2].

AS1938909 is a SHIP2 inhibitor that works by increasing Akt phosphorylation, glucose consumption, and glucose uptake in L6 myotubes, specifically upregulating the GLUT1 gene.

AS1949490 activated glucose metabolism via up-regulation of GLUT1 gene in L6 myotubes[1][2]. AS1949490 is a potent and selective SHIP-2 (SH2 domain-containing inositol 5′ phosphatase 2) inhibitor, with an IC50 of 620 nM.
