Mcl-1 inhibitor 6 is a potent, orally active small molecule that selectively targets the anti-apoptotic protein myeloid cell leukemia 1 (Mcl-1). Mcl-1 inhibitor 6 binds with high affinity, with a dissociation constant (K d) of 0.23 nM, and exhibits binding activity with a K i of 0.02 μM. Mcl-1 inhibitor 6 displays exceptional selectivity over other anti-apoptotic Bcl-2 family proteins, including Bcl-2, Bcl2A1, Bcl-xL, and Bcl-w, all of which display binding constants greater than 10 μM. Notably, Mcl-1 inhibitor 6 demonstrates strong antitumor activity in preclinical models, highlighting its potential as a therapeutic candidate in oncology.

| In vitro | Methods: H929 cells were treated with Mcl-1 inhibitor 6 (0.1, 5 μM, 4 h), and the expression of related proteins was analyzed by Western Blot. Results: After treatment with Mcl-1 inhibitor 6, PARP cleavage was significantly upregulated in a concentration-dependent manner. [1] |
| In vivo | Methods: Mcl-1 inhibitor 6 (20, 60 mg/kg, administered every 2 days for 14 days) was administered to Balb/c nude mice bearing MV4-11 xenograft tumors via intraperitoneal injection or oral gavage to investigate the antitumor activity of Mcl-1 inhibitor 6. Results: Mcl-1 inhibitor 6 demonstrated significant tumor growth inhibition in vivo. [1] |
