KPT 330 is a chromosome maintenance protein 1 (CRM1) inhibitor. KPT 330 suppresses downstream effectors of B-cell activation, proliferation and migration in chronic lymphocytic leukemia cells.
||MOLT-4, Jurkat, HBP-ALL, KOPTK-1, SKW-3, and DND-41 cell lines
||Culturing cell lines in RPMI 1640 medium, supplemented with 10% fetal bovine serum and penicillin/streptomycin.Using cell Titer Glo assay to assess cell viability upon treatment with either dimethyl sulfoxide (DMSO) or KPT-330. Plating cells at a density of 10 000 cells per well in a 96-well plate and incubating them with DMSO or increasing concentrations of KPT-330. After 72 h exposure to KPT-330 ,mearsuring the cell viability and reporting as a percentage of DMSO control cells. Jurkat cells that overexpress BCL2 are generated using MSCV-IRES-GFP retroviral expression system. Jurkat cells infected with BCL2 or control vector viruses are sorted by flow cytometry and the expression of BCL2 confirmed by Western blot analysis using BCL2 antibody

|Animal A (mg/kg) = Animal B (mg/kg) multiplied by
||Animal B Km
|Animal A Km
For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.

KPT-330 inhibitor of CRM1 (XPO1)-mediated nuclear export has selective anti-leukaemic activity in preclinical models of T-cell acute lymphoblastic leukaemia and acute myeloid leukaemia.
