5F-203 (NSC-703786) exhibits its anticancer properties through a multimodal mechanism of action. As a DNA-damaging agent, it creates stable adducts while arresting cell cycle progression. The compound's ability to strongly activate AhR signaling results in marked CYP1A1 induction. Additional effects include ROS generation and concurrent activation of multiple stress-responsive kinase pathways (JNK, ERK, and p38), collectively contributing to its cytotoxic profile.

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.
