Background:
IC50: N/A
FRAX1036 is a p21-activated kinase I (PAK1) inhibitor.
Breast cancer is a clinically and molecularly heterogeneous disease and plenty of genetic and epigenetic studies of breast tumors has revealed novel putative driver genes, such as p21-activated kinase (PAK)1. As a serine/threonine kinase downstream of small GTP-binding proteins including Rac1 and Cdc42, PAK1 is an critical component of growth factor signaling networks and cellular functions important to tumorigenesis.
In vitro: Previous study demonstrated that the administration of docetaxel with either FRAX1036 or PAK1 small interfering RNA oligonucleotides was able to alter signaling to cytoskeletal-associated proteins dramatically, such as stathmin, and also able to induce microtubule disorganization and cellular apoptosis. In addition, the live-cell imaging data showed that the duration of mitotic arrest mediated by docetaxel could be significantly reduced by the treatment of FRAX1036, which was associated with increased kinetics of apoptosis [1].
In vivo: In previous animal study, the untreated mice bearing KT21 transplants showed ventricular invasion, whereas Ben-Men grew at the injection site. Efficacy results found that the treatment with Frax1036 could lead to a slower tumor growth, with reduction in body mass index (BMI) signals of 37% when compared to vehicle cohort [2].
Clinical trial: Up to now, FRAX1036 is still in the preclinical development stage.
