Description

Plinabulin salt crystal form Technical Field

[0001] The present invention relates to the field of pharmaceutical chemistry, in particular to a crystalline form of Plinabulin salt, and a preparation method and application thereof. Background Art

[0002] Plinabulin ((3Z,6Z)-3-[(5-tert-butyl-1H-imidazol-4-yl)methylene]-6-(benzylidene)-2,5-piperazinedione) is a synthetic analog of the diketopiperazine phenylahistin (phenyltrimethylammonium chloride) found in marine and terrestrial Aspergillus species. Its structure is shown below:

[0003] Plinabulin is structurally distinct from colchicine and its combretastatin-like analogs (e.g., combretastatin phosphate) and binds at or near the colchicine binding site on tubulin monomers. Previous studies have shown that Plinabulin at low concentrations induces vascular endothelial cell tubulin depolymerization and monolayer permeability compared to colchicine, and have been shown to induce apoptosis in Jurkat leukemia cells. Studies of Plinabulin as a single agent in patients with advanced malignancies (lung, prostate, and colon cancer) have demonstrated favorable pharmacokinetic, pharmacodynamic, and safety profiles.
