Tasidotin
Tasidotin (ILX651 free base) is a tubulin inhibitor and competitive Prolyl Endopeptidase (PREP) inhibitor, with an IC50 of 10 μM against bovine tubulin. Tasidotin exhibits high cerebrospinal fluid penetration in non-human primates. Tasidotin antagonizes microtubule assembly and induces an extended assembly lag phase, thereby inhibiting mitosis and cell proliferation, and exerts cytotoxic and oncolytic effects on cancer cells. Tasidotin is metabolized into polypeptides and proline inside cells, and its in vivo metabolism is mediated by prolyl endopeptidase. Tasidotin can be applied in research related to Burkitt's lymphoma, breast cancer, leukemia, melanoma, central nervous system malignancies and various solid tumors.

Biological Activity
Tasidotin inhibits the growth of Burkitt's lymphoma CA46 cells, with an IC50 of 100 nM[1].
Tasidotin inhibits the growth of MCF-7 human breast cancer cells with an IC50 of 150 nM[1].
Tasidotin (2-300 nM; 70 nM) potently inhibits the proliferation of various tumor cell lines in vitro, with IC50 values ranging from 2 to 300 nM; at a concentration of approximately 70 nM, it suppresses mitosis and cell proliferation by affecting microtubule dynamics[2].

Animal Model:Macaca mulatta (adult male, 11.4-15.9 kg)[2]
-
Dosage:0.75 mg/kg
-
Administration:i.v.; single dose; 30 minutes infusion
-
Result:Achieved a mean CSF:plasma AUC ratio of 1.1.
Had a mean plasma AUC of 30 μM min, mean plasma half-life of 27 min, and mean plasma clearance of 44 mL/min/kg.
Had a mean CSF AUC of 28 μM min, with a mean CSF half-life of 96 min.
Reached peak CSF concentrations ranging from 53 to 272 nM, exceeding 70 nM for 2.5-3.5 hours in three of four animals.
Was well tolerated with no significant clinical or laboratory toxicity.
