Description A-1210477 is a potent and selective MCL-1 inhibitor with Ki and IC50 of 0.454 nM and 26.2 nM, respectively, >100-fold selectivity over other Bcl-2 family members.
MCL-1 [1]
(Cell-free assay)
26.2 nM
In vitro

In H929 cells, A-1210477 binds to MCL-1 with high affinity and induces MCL-1 protein elevation. In H929, H2110, and H23 cells, A-1210477 induce the hallmarks of apoptosis, and inhibits MCL-1-dependent cell viability. A-1210477 also synergizes with navitoclax to kill a variety of cancer cell lines. [1] In SKBR3 cells, A-1210477 inhibits MCL-1–BIM interaction and induces classical features of apoptosis. [2] In addition, A-1210477 sensitizes non-Hodgkin's lymphoma cell lines to venetoclax (ABT-199). [3]

Protocol (from reference)

Kinase Assay:[1]
  • Binding affinity assays:

    TR-FRET-binding affinity assays are performed for BCL-2, BCL-XL, and MCL-1 in 4.52 mM monobasic potassium phosphate, 15.48 mM dibasic potassium phosphate, 1 mM sodium EDTA, 0.05% Pluronic F-68 detergent, 50 mM sodium chloride, and 1 mM DTT (pH 7.5). For MCL-1 assays, GST-tagged MCL-1 (1 nM) is mixed with 100 nM f-Bak, 1 nM Tb-labeled anti-GST antibody, and compound at room temperature (RT) for 60 min. Fluorescence is measured on an Envision plate reader using a 340/35 nm excitation filter and 520/525 (f-Bak) and 495/510 nm (Tb-labeled anti-GST antibody) emission filters.

Cell Research:[1]
  • Cell lines: H929, H2110, and H23 cells
  • Concentrations: ~30 μM
  • Incubation Time: 48 h or 72 h
  • Method: Adherent cell lines are seeded at 50 000 cells per well in 96-well plates and treated for 48 h with compounds diluted in half-log steps starting at 30 μM and ending at 0.001 μM. Multiple myeloma cell lines were seeded at 15 000–20 000 cells per well and treated similarly. Effects on proliferation and viability were determined using CellTiter-Glo reagent according to the manufacturer’s instructions. IC50 values are determined by non-linear regression analysis of the concentration response data.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
