ZSH-2208 is a synthetic analog of all-trans retinoic acid (ATRA) designed to overcome resistance and improve differentiation therapy in acute promyelocytic leukemia (APL) and other malignancies. In published studies, ZSH-2208 has shown superior anti-proliferative and pro-differentiation activity compared to ATRA in ATRA-resistant APL cell lines such as NB4-R2. For example, ZSH-2208 induced significant G1 phase arrest and granulocytic differentiation in NB4-R2 cells at concentrations around 1–10 µM, whereas ATRA was largely ineffective at equivalent doses. In mouse xenograft models, ZSH-2208 treatment led to marked tumor growth inhibition without the rapid metabolic degradation seen with ATRA. These data suggest that ZSH-2208 is a promising candidate for treating retinoic acid-resistant leukemias and potentially other cancers sensitive to retinoid signaling.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
