Synthesis and Optimization of Kv7 (KCNQ) Potassium Channel Agonists: The Role of Fluorines in Potency and Selectivity
Liu, Ruiting,Tzounopoulos, Thanos,Wipf, Peter
supporting information, p. 929 - 935 (2019/06/13)
Based on the potent Kv7 agonist RL-81, we prepared new lead structures with greatly improved selectivity for Kv7.2/Kv7.3 over related potassium channels, i.e., Kv7.3/Kv7.5, Kv7.4, and Kv7.4/7.5. RL-36 and RL-12 maintain an agonist EC2x of ca. 1 μM on Kv7.2/Kv7.3 in a high-throughput assay on an automated electrophysiology platform in HEK293 cells but lack activity on Kv7.3/Kv7.5, Kv7.4, and Kv7.4/7.5, resulting in a selectivity index SI > 10. RL-56 is remarkably potent, EC2x 0.11 ± 0.02 μM, and still shows an SI = 2.5. We also identified analogues with significant selectivity for Kv7.4/Kv7.5 over Kv7.2/Kv7.3. The extensive use of fluorine in iterative core structure modifications highlights the versatility of these substituents, including F, CF3, and SF5, to span orders of magnitude of potency and selectivity in medicinal chemistry lead optimizations.

Triple negative breast cancer (TNBC) remains a serious unmet medical need with discouragingly high relapse rates. We report here the synthesis and structure-activity relationship (SAR) of a novel series of 2,4,5-trisubstituted-7H-pyrrolo[2,3-d]pyrimidines with potent activity against TNBC tumor cell lines. These compounds were discovered from a TNBC phenotypic screen and possess a unique dual inhibition profile targeting TTK (mitotic exit) and CLK2 (mRNA splicing). Design and optimization, driven with a TNBC tumor cell assay, identified potent and selective compounds with favorable in vitro and in vivo activity profiles and good iv PK properties. This cell-based driven SAR produced compounds with strong single agent in vivo efficacy in multiple TNBC xenograft models without significant body weight loss. These data supported the nomination of CC-671 into IND-enabling studies as a single agent TNBC therapy.
