LXG6403 is a potent, irreversible lysyl oxidase (LOX) inhibitor with an IC₅₀ of 1.3 μM in MDA-MB-231 cells, demonstrating approximately 3.5-fold selectivity over LOXL2 and no activity against LOXL1. It effectively inhibits LOX activity across multiple triple-negative breast cancer (TNBC) cell lines, including HCC143, Hs-578-T, and HCC1937, with IC₅₀ values below 5 μM. In preclinical models, LXG6403 enhances chemosensitivity to agents such as doxorubicin, cisplatin, and paclitaxel by disrupting collagen crosslinking, thereby reducing tumor stiffness, improving drug penetration, inhibiting FAK signaling, and inducing ROS-mediated DNA damage leading to G1 arrest and apoptosis. Notably, in the TM01278 TNBC patient-derived xenograft model, LXG6403 overcame doxorubicin resistance without significant toxicity, underscoring its potential as a therapeutic agent in LOX-driven, chemoresistant cancers

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.
