What is 2-(4-HYDROXY-3-METHOXYPHENYL)BENZOTHIAZOLE?

Biological Activity

YL-109 is a novel antitumor agent that inhibits the growth and invasion of breast cancer cells in vitro and in vivo.

in vitro

YL-109 (0.001-10 μM; 96 h or 24 h) inhibits cell proliferation, motility, and invasiveness in breast cancer cells.
YL-109 (1 μM) increases both CHIP mRNA and protein levels in MDA-MB-231 cells.

Cell Proliferation Assay

< td class="col2"> MCF-7 and MDA-MB-231 cells

Cell Line:
Concentration:	0.001, 0.01, 0.1, 1, 10 μM
Incubation Time:	96 hours
Result:	Strongly inhibited cell proliferation of MCF-7 and MDA-MB-231 cells in a dose-dependent manner (IC ₅₀ =85.8 nM and 4.02 μM, respectively).

in vivo

YL-109 (15 mg/kg; sc for every 2 d) inhibits both tumor growth and cancer metastasis of breast cancer cells in vivo.

< /p>

Animal Model:	BALB/cAjcl-nu/nu female mice (4-5 weeks) inoculated with MCF-7 or MDA-MB-231 cells
Dosage:	15 mg/kg
Administration: < /td>	Sc every 2 days for 63 days
Result:	Suppressed tumor growth in mice injected with MCF-7 and MDA-MB-231 cells.
