OTX008是半乳糖凝集素-1(Galectin-1)的选择性抑制剂。
Cas No.:286936-40-1
Sample solution is provided at 25 µL, 10mM.
OTX008 is a selective inhibitor of galectin-1 [1]. OTX008 specifically binds to the β-pleated folded domain of Gal-1, inducing oxidation and proteasomal degradation, thereby inhibiting tumor cell proliferation, invasion, and angiogenesis [2]. OTX008 is indicated for the treatment of various solid tumors [3-4].
In ARPE-19 cells, OTX008 (2.5-10µM; 4h) treatment significantly increased cell viability in high glucose [5]. In OSSC cells, OTX008 (12.5-100μg/mL; 24-72h) reduces cell viability in a dose-dependent manner [6].
In SQ20B cells xenograft mice model, OTX008 (10mg/kg; ip; 21d) inhibits tumor growth [7]. In 293FT cells xenograft mice model, OTX008 (3mg/kg; ip; 3d) inhibits tumor growth [8].

| Cell experiment [1]: | |
Cell lines | ARPE-19 cells |
Preparation Method | Human ARPE-19 cells were cultured in Dulbecco's Modified Eagle Medium/Nutrient Mixture F12 (DMEM/F12) at 37℃ and 5% CO2 with 5mM glucose. The culture medium was supplemented with 10% heat-inactivated fetal bovine serum (FBS), 1% penicillin/streptomycin solution (P/S), 1% L-glutamine (L-Glu), 5mM Hepes, and 7.5% NaHCO3. Two days after plating, cells were split and seeded into separate culture dishes at varying cell densities for each experiment. For the first three days, cells were exposed to 5mM D-glucose (normal glucose, NG); 35mM D-glucose (high glucose, HG); and 5mM D-glucose and 30mM mannitol (NG+M) (as a negative control for high glucose) at 37℃ and 5% CO2. Then, after 72h of NG or HG stimulation, OTX008 was dissolved in 0.1% w/v dimethyl sulfoxide (DMSO) as a vehicle or 0.1% DMSO in fresh cell culture medium (NG or HG) and added daily until day 9. |
Reaction Conditions | 2.5-10µM; 4h |
Applications | OTX008 treatment significantly increased cell viability in high glucose. |
| Animal experiment [2]: | |
Animal models | SQ20B cells xenograft mice model |
Preparation Method | For the xenograft model, female athymic nude mice (Nu/Nu, 5-6 weeks old) were inoculated subcutaneously with tumor cells into the right abdominal cavity. When tumors reached approximately 100 cubic millimeters, animals were randomly assigned to treatment groups and began receiving OTX008. A total of 92 animals were inoculated, and 76 tumor-bearing animals were randomized before the start of intervention. |
Dosage form | 10mg/kg; ip; 21d |
Applications | OTX008 inhibits tumor growth. |
