Antiproliferative agent-83

Antiproliferative agent-83 is an orally active STAT3 inhibitor (K_d = 5.63 μM) with antiproliferative activity against Huh-7 cells (IC₅₀ = 1.30 μM). Antiproliferative agent-83 inhibits dual phosphorylation of STAT3 at tyrosine and serine residues, blocking nuclear translocation and downstream transcriptional activation. Antiproliferative agent-83 induces apoptosis, ROS accumulation, and mitochondrial depolarization. Antiproliferative agent-83 suppresses tumor growth in a hepatocellular carcinoma xenograft mouse model. Antiproliferative agent-83 can be used for research on hepatocellular carcinoma.

Anti-cancer

Apoptosis

Antiproliferative agent-83 (2 μM; 24 h) upregulates cleaved caspase-3 and Bax and downregulates Bcl-2 in Huh-7 cells^[1].

Mitochondrial Function

Antiproliferative agent-83 (0.5-4 μM; 24 h) inhibits ATP production in Huh-7 cells with an IC₅₀ of 1.55 μM^[1].

Oxidative Stress

Antiproliferative agent-83 (0.25-1 μM; 24 h; 0.5 μM combined with 5 mM NAC; 24 h) increases ROS in Huh-7 cells, and this increase can be reversed by NAC^[1].

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.
