Storage & Solubility Information
| Description | OTX008 (PTX008) is a selective galectin-1 inhibitor. |
| In vitro | OTX008 inhibits Gal1 expression and ERK1/2 and AKT-dependent survival pathways in SQ20B and A2780-1A9 cells and induces G2/M cell cycle arrest through CDK1. OTX008 increases the anti-proliferative effects of Semaphorin-3A (Sema3A) in SQ20B cells and reverses invasion induced by exogenous Gal1. Growth inhibitory concentrations (GI50) of OTX008 range from 3 to 500 μM in a large panel of human solid tumor cell lines. A significant correlation between OTX008 GI50 values and Gal1 mRNA (LGALS1) and protein expression levels in the panel of cancer cells is observed. OTX008 affects endothelial cell proliferation, motility, invasiveness, and cord formation. Tumor cell proliferation is also inhibited, with differences in sensitivity among cell lines (IC50 from 1 to 190 μM)[1][2]. |
| In vivo | OTX008 treatment is associated with the down-regulation of Gal1 and Ki67 in treated tumors, as well as decreased microvessel density and VEGFR2 expression. OTX008 inhibits the growth of A2780-1A9 xenografts. Combination studies display OTX008 synergy with several cytotoxic and targeted therapies, principally when OTX008 is administered first[1]. |

Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:
For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Stock Solution Preparation:
Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
Preparation of the In Vivo Formulation:
1) Add 100 μL of the DMSO stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.
