3AC is an inhibitor of SH2 domain-containing inositol-5’-phosphatase 1 (SHP-1). It is selective for SHP-1 over SHP-2 and phosphatase and tensin homolog (PTEN). 3α-Aminocholestane induces hyperactivation of the tyrosine kinase SYK in patient-derived Ph+ acute lymphoblastic leukemia (ALL) cells and selectively induces cytotoxicity in these cells over mature B cell lymphoma cells. It reduces leukemia burden and increases survival in a tyrosine kinase inhibitor-resistant patient-derived Ph+ ALL mouse xenograft model when administered at a dose of 50 mg/kg. 3α-Aminocholestane reduces cell viability of OPM2 multiple myeloma (MM) cells in a concentration-dependent manner and of RPMI8226 MM cells when used at concentrations greater than or equal to 12.5 μM. It halts the cell cycle at the G0/G1 or G2/M stages in the highly proliferative OPM2 or less proliferative RPMI8226 cell lines, respectively. It induces apoptosis via activation of caspase-3, caspase-9, and poly(ADP-ribose) polymerase (PARP) in OPM2 cells but not in RPMI8226 cells. 3α-Aminocholestane reduces tumor burden and increases survival in an OPM2 mouse xenograft model.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
