MT125​​ is a brain-penetrant small-molecule inhibitor selectively targeting non-muscle myosin IIA/B (NMIIA/B) with >20-fold specificity over cardiac myosin. It demonstrates potent anti-glioblastoma activity by: (1) blocking tumor invasion and cytokinesis (inducing polyploidy), (2) disrupting mitochondrial dynamics to elevate ROS and trigger ferroptosis, and (3) sensitizing tumors to radiotherapy/kinase inhibitors via ROS-driven PDGFR/mTOR pathway activation. Subcutaneous administration achieves brain concentrations twice plasma levels (t_1/2~10.5 hr) with no toxicity observed at 15× the therapeutic dose in rats. MT-125 monotherapy extends survival in GBM models, while combinations with PDGFR/PI3K inhibitors induce long-term remission (>40% mice). Its first-in-class mechanism, safety profile, and CNS bioavailability support clinical development for glioblastoma.

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.
