Antiplasmodial imidazopyridazines: structure-activity relationship studies lead to the identification of analogues with improved solubility and hERG profiles

3,6-Diarylated imidazopyridazines have recently been shown to possess good in vitro antiplasmodial and in vivo antimalarial activity. However, frontrunner compounds have been associated with poor solubility and a hERG (human ether-a-go-go-related gene) inhibition liability raising concerns for potential cardiotoxicity risks. Herein, we report the synthesis and structure-activity relationship studies of new imidazopyridazines aimed at improving aqueous solubility and countering hERG inhibition while maintaining antiplasmodial potency. While we identified new analogues with potent antiplasmodial activity (IC50 = 0.031 μM against the NF54 drug-sensitive strain, and IC50 = 0.0246 μM against the K1 multidrug resistant strain), hERG inhibition remained an issue. Excitingly, on the other hand, new analogues with a substantially improved hERG inhibition profile (IC50 = 7.83-32.3 μM) with sub-micromolar antiplasmodial activity (NF54, IC50 = 0.151-0.922 μM) were identified. Similarly, the introduced molecular features also resulted in analogues with moderate to high solubility (60-200 μM) while also displaying sub-micromolar antiplasmodial potency (NF54, IC50 = 0.136-0.99 μM).
Iridium-catalyzed silylation of aryl C-H bonds
Cheng, Chen,Hartwig, John F.
supporting information, p. 592 - 595 (2015/01/30)
A method for the iridium-catalyzed silylation of aryl C-H bonds is described. The reaction of HSiMe(OSiMe3)2 with arenes and heteroarenes catalyzed by the combination of [Ir(cod)(OMe)]2 and 2,4,7-trimethylphenanthroline occurs with the aromatic compound as the limiting reagent and with high levels of sterically derived regioselectivity. This new catalytic system occurs with a much higher tolerance for functional groups than the previously reported rhodium-catalyzed silylation of aryl C-H bonds and occurs with a wide range of heteroarenes. The silylarene products are suitable for further transformations, such as oxidation, halogenation, and cross-coupling. Late-stage functionalization of complex pharmaceutical compounds was demonstrated.

Medicinal chemistry optimization of antiplasmodial imidazopyridazine hits from high throughput screening of a SoftFocus kinase library: Part 1
Le Manach, Claire,Gonzàlez Cabrera, Diego,Douelle, Frederic,Nchinda, Aloysius T.,Younis, Yassir,Taylor, Dale,Wiesner, Lubbe,White, Karen L.,Ryan, Eileen,March, Corinne,Duffy, Sandra,Avery, Vicky M.,Waterson, David,Witty, Michael J.,Wittlin, Sergio,Charman, Susan A.,Street, Leslie J.,Chibale, Kelly

A novel class of imidazopyridazines identified from whole cell screening of a SoftFocus kinase library was synthesized and evaluated for antiplasmodial activity against K1 (multidrug resistant strain) and NF54 (sensitive strain). Structure-activity relationship studies led to the identification of highly potent compounds against both strains. Compound 35 was highly active (IC 50: K1 = 6.3 nM, NF54 = 7.3 nM) and comparable in potency to artesunate, and 35 exhibited 98% activity in the in vivo P. berghei mouse model (4-day test by Peters) at 4 × 50 mg/kg po. Compound 35 was also assessed against P. falciparum in the in vivo SCID mouse model where the efficacy was found to be more consistent with the in vitro activity. Furthermore, 35 displayed high (78%) rat oral bioavailability with good oral exposure and plasma half-life. Mice exposure at the same dose was 10-fold lower than in rat, suggesting lower oral absorption and/or higher metabolic clearance in mice.
