proto-1

PROTO-1 displays obviously protection of hair cells, with HC50(concentration that would produce 50% hair cell survival) of 1 μM-10 μM (1 μM≤HC50≤10 μM).

Cbl-b-IN-3 is a potent inhibitor of casitas b lineage lymphoma proto-oncogene-b (Cbl-b) (ic50 < 1 nM).

RGB-1, a small molecule that selectively stabilizes the RNA G-quadruplex structure, enhances G-quadruplex-mediated inhibition of RNA translation in mammalian cells and reduces NRAS proto-oncogene expression in breast cancer cells.

Sutetinib is an orally effective tyrosine kinase inhibitor that targets enzymes linked to tumor growth and angiogenesis, such as VEGFR (VEGFR-1 2 3 with Ki= 0.009 µM), PDGFR (PDGFR-α β with Ki= 0.008 µM), and the proto-oncogene cKIT. It inhibits the proliferation, migration, and tubular structure formation of endothelial and fibroblast cells, demonstrating antitumor activity across various cancer cell lines.
