Catalog No. Product Name Information Selective / Pan IC50 / Ki
S7126 Marinopyrrole A (Maritoclax)

Marinopyrrole A (Maritoclax) is a selective Mcl-1 antagonist. It binds to Mcl-1, but not Bcl-XL, and targets Mcl-1 for proteasomal degradation. Maritoclax disrupts the interaction between Bim and Mcl-1 with an IC50 of 10.1 μM.

Selective
S8758 VU661013

VU661013 is a novel, potent, selective MCL1 inhibitor with Ki of 97 ± 30 pM of human MCL-1 in a TR-FRET assay. However, VU661013 does not significantly inhibit BCL-xL or BCL-2 with Ki > 40 μM or = 0.73 μM. VU661013 de-stabilizes BIM/MCL-1 association, leads to apoptosis in AML.

Selective MCL1, Ki: 97 pM
S8643 AZD5991

AZD5991 is a macrocyclic MCL-1 inhibitor with sub-nanomolar affinity for MCL-1 (Ki = 0.13 nM). The binding affinity of AZD5991 is about 25-fold lower for mouse Mcl-1 vs. human Mcl-1 but only four-fold lower for rat Mcl-1.

Selective Mcl-1, Ki: 0.13 nM; Mcl-1, IC50: 0.7 nM
S8383 S63845

S63845 is a new, selective MCL-1 inhibitor with the Kd value of 0.19 nM and has no discernible binding to the other BCL-2 members, BCL-2 or BCL-XL.

Selective human MCL-1, Kd: 0.19 nM
S8836 S64315 (MIK665)

S64315 (MIK665) is an inhibitor of induced myeloid leukemia cell differentiation protein Mcl-1 with Ki value of 1.2 nM and has potential pro-apoptotic and antineoplastic activities.

Selective Mcl-1, Ki: 1.2 nM
S7790 A-1210477

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.

Selective MCL-1, IC50: 26.2 nM
S7531 UMI-77

UMI-77 is a selective Mcl-1 inhibitor with Ki of 490 nM, showing selectivity over other members of Bcl-2 family.

Selective Mcl-1, Ki: 490 nM
S9665 Motixafortide (BL-8040)

Motixafortide (BL-8040, BKT140, TF 14016, 4-fluorobenzoyl, 4F-benzoyl-TN14003, T140) is an antagonist of CXCR4 with IC50 of ~1 nM. BL-8040 induces the apoptosis of AML blasts by down-regulating ERK, BCL-2, MCL-1 and cyclin-D1 via altered miR-15a/16-1 expression.

Selective
S2812 (R)-(-)-Gossypol acetic acid

(R)-(-)-Gossypol (AT-101) acetic acid, the R-(-) enantiomer of Gossypol acetic acid, binds with Bcl-2, Bcl-xL and Mcl-1 with Ki of 0.32 μM, 0.48 μM and 0.18 μM in cell-free assays; does not inhibit BIR3 domain and BID. AT-101 simultaneously triggers apoptosis and a cytoprotective type of autophagy. Phase 2.

Pan Mcl-1, Ki: 0.18 μM
S8061 Sabutoclax

Sabutoclax (BI-97C1) is a pan-Bcl-2 inhibitor, including Bcl-xL, Bcl-2, Mcl-1 and Bfl-1 with IC50 of 0.31 μM, 0.32 μM, 0.20 μM and 0.62 μM, respectively.

Pan Mcl-1, IC50: 0.20 μM
S1121 TW-37

TW-37 is a novel nonpeptide inhibitor to recombinant Bcl-2, Bcl-xL and Mcl-1 with Ki of 0.29 μM, 1.11 μM and 0.26 μM in cell-free assays, respectively.

Pan Mcl-1, Ki: 0.26 μM
S2448 Gambogic Acid

Gambogic Acid (Guttatic Acid, Guttic Acid, Beta-Guttiferrin) activates caspases with EC50 of 0.78-1.64 μM and competitively inhibits Bcl-XL, Bcl-2, Bcl-W, Bcl-B, Bfl-1 and Mcl-1 with IC50 of 1.47, 1.21, 2.02, 0.66, 1.06 and 0.79 μM, respectively.

Pan Mcl-1, IC50: 0.79 μM
