TMLB-G9

TMLB-G9 is an orally active B3GAT3 inhibitor (human K_d = 0.72 μM). TMLB-G9 blocks glycosaminoglycan biosynthesis and inhibits chondroitin sulfate biosynthesis in hepatocellular carcinoma cells. TMLB-G9 induces apoptosis by upregulating cleaved PARP and cleaved caspase-3. TMLB-G9 induces G0/G1 cell cycle arrest by upregulating Rb and downregulating CDK1, CDK2, Cyclin A2, Cyclin E1, and phosphorylated Rb. TMLB-G9 inhibits migration and invasion by reversing epithelial-mesenchymal transition, manifested as upregulation of E-cadherin and downregulation of N-cadherin, vimentin, MMP-2, MMP-9, and ZEB1. TMLB-G9 inhibits colony formation. TMLB-G9 exhibits broad-spectrum antitumor activity against multiple cancer cell lines. TMLB-G9 can be used for research on hepatocellular carcinoma.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
