Protocol

Cell experiment [1-3]:

Cell lines

HL-60 cells, follicular lymphoma B cell lines, HF1A3, HF4.9 and HF28RA cells

Preparation method

The solubility of this compound in DMSO is >20.5 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

50 μM, 4 h

Applications

In HL-60 cells, HA14-1 induced cell death in a dose-dependent manner. HA14-1 (50 μM) caused the loss of viability in more than 90% of the cells. In HL-60 cells, treatment with 50 μM HA14-1 by 3 h displayed the characteristic pattern of DNA fragmentation. HA14-1 decreased cell viability and induced apoptosis in follicular lymphoma B cell lines, HF1A3, HF4.9 and HF28RA cells. HA14-1 (10-20 μmol/L) increased sensitivity of human glioblastoma cells to radiotherapy-induced apoptosis and chemotherapy-induced apoptosis.

Animal experiment [3]:

Animal models

Swiss nude mice challenged with BeGBM cells

Dosage form

Intraperitoneal injection, 400 nM, once weekly from day 2

Application

In Swiss nude mice challenged with BeGBM cells, HA14-1 (400 nmol, once weekly from day 2) did not have any significant effect on the growth of glioblastoma tumors in immunodeficient mice. HA14-1 (400 nM) increased the effect of the DNA-damaging agent etoposide (2.5 mg/kg) on glioblastoma growth in vivo.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background

HA14-1 is a potent small-molecule inhibitor of B-cell lymphoma 2 (Bcl-2), a protein factor binding to and inactivating pro-apoptotic proteins (such as Bax and BH3-only family proteins) to suppress apoptosis, that potently inhibits the anti-apoptotic of Bcl-2 and induces apoptosis with values of 50% inhibition concentration IC50 ranging from 10 to 20 μM in NIH3T3, HL60 and lung cancer H1299 cell lines. HA14-1 binds to Bcl-2 by mimicking the BH3 domain required for homo- and hetero-dimer formation and hence prevents the binding of these proteins subsequently resulting in the inhibition of Bcl-2. HA14-1 has been widely investigated in studies of apoptosis, which potentiates it to be used for the treatment of cancer.
