How to use

In Vitro:

1G244 (0-100 μM; 72 hours; Delta47, U266 , KMS-5, RPMI8226, or MM.1 S cells) treatment dose-dependently decreases viable cell number of five multiple myeloma cell lines. 1G244 (50 μM; 0-48 hours; MM.1 S cells) treatment induces apoptosis, as cleaved forms of both caspase-3 and PARP are detected.

In Vivo:

1G244 (30 mg/kg; subcutaneous injection; once-a-week; for 3 weeks; NOG female mice) treatment apparently suppresses the subcutaneous growth of MM.1 S cells in murine xenograft model.
