| 动物实验 |
GIST48B xenograft model: Female nude mice (6-7 weeks old) were subcutaneously inoculated with 5×10⁶ GIST48B cells into the right flank. When tumors reached an average volume of 120 mm³, mice were randomly divided into four groups (n=8 per group): vehicle control, Batoprotafib (TNO-155) 10 mg/kg, 30 mg/kg, and 60 mg/kg. The compound was formulated in 0.5% carboxymethylcellulose sodium (CMC-Na) aqueous solution and administered via oral gavage once daily for 21 consecutive days. Tumor volume (length × width² / 2) and body weight were recorded every 3 days. At the end of the study, mice were euthanized, tumors were excised and weighed, and tumor tissues were collected for immunohistochemical staining [2]

- No significant changes in hematological parameters (white blood cell count, red blood cell count, platelet count) or biochemical markers of liver/kidney function (ALT, AST, creatinine, urea nitrogen) were observed in treated mice [2] |

| 其他信息 |
Batoprotafib is an inhibitor of protein tyrosine phosphatase (PTP) non-receptor type 11 (SHP2; src homology region 2 domain phosphatase; PTPN11), with potential antineoplastic activity. Upon oral administration,batoprotafib binds to and inhibits SHP2. This prevents SHP2-mediated signaling, inhibits MAPK signaling and prevents growth of SHP2-expressing tumor cells. SHP2, an oncoprotein overexpressed in a variety of cancer cell types, regulates cell survival, differentiation and proliferation through activation of the RAS-RAF-ERK signaling pathway. SHP2 also regulates programmed cell death 1 (PD-1)-mediated signal transduction and is involved in immune checkpoint modulation.
Batoprotafib (TNO-155) is a potent, orally active, and selective inhibitor of PDGFRα D842V mutant kinase, developed for the treatment of PDGFRα D842V-driven gastrointestinal stromal tumors (GIST) [2] - Its mechanism of action involves selective binding to the ATP-binding pocket of PDGFRα D842V kinase, inhibiting its catalytic activity and blocking downstream JAK/STAT5, PI3K/AKT, and MAPK/ERK signaling pathways, thereby inducing cell cycle arrest and apoptosis in GIST cells [2] - PDGFRα D842V is a common primary resistance mutation to imatinib in GIST patients; Batoprotafib (TNO-155) addresses this unmet medical need by specifically targeting the mutant kinase [2] - Literature [1] refers to Batoprotafib (TNO-155) as part of new clinical trials for disseminated GIST, highlighting its potential in treating advanced or refractory GIST with PDGFRα D842V mutation [1] |
