Biological Activity

Description A-1331852 is a potent and selectiveBCL-XL inhibitor with Ki value less than 0.01 nM for BCL-XL and 6 nM, 4 nM, 142 nM for Bcl-2, Bcl-W, MCL-1 respectively. It may be useful in the treatment of cancer, immune and autoimmune diseases.
Targets
Bcl-xL [1]
(Cell-free assay)
<0.01 nM(Ki)
In vitro A-1331852 exhibits remarkable potency both as a single agent and in combination with TKIs in killing primary CD34+ CML cell. Also, It has remarkable potency in inducing apoptosis in these cells at low nanomolar concentrations as early as 1 h post-treatment[2].
In vivo A-1331852 demonstrates antitumor efficacy in the Molt-4 xenograft model, inducing tumor regressions as a single agent[1].

Protocol (from reference)

Cell Assay:[2]
  • Cell lines

    K562 cells

  • Concentrations

    100 nM

  • Incubation Time

    0-2 h

  • Method

    Immunoprecipitation of BCL-XL is carried out in K562 cells, exposed to A-1331852 (100 nM) for 0-2 h, and the eluted complexes are immunoblotted for the indicated proteins. The input cell lysates and the immunodepleted supernatant (labeled as Flow-through) are immunoblotted to check the efficiency of the immunoprecipitation.

Animal Study:[1]
  • Animal Models

    SCID and SCID-bg mice

  • Dosages

    25 mg/kg

  • Administration

    Oral administration
