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 muM against the NF54 drug-sensitive strain, and IC50 = 0.0246 muM 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 muM) with sub-micromolar antiplasmodial activity (NF54, IC50 = 0.151-0.922 muM) were identified. Similarly, the introduced molecular features also resulted in analogues with moderate to high solubility (60-200 muM) while also displaying sub-micromolar antiplasmodial potency (NF54, IC50 = 0.136-0.99 muM).

Design, synthesis, and biological evaluation of novel oxadiazole- and thiazole-based histamine H3R ligands

Histamine H3 receptor (H3R) is largely expressed in the CNS and modulation of the H3R function can affect histamine synthesis and liberation, and modulate the release of many other neurotransmitters. Targeting H3R with antagonists/inverse agonists may have therapeutic applications in neurodegenerative disorders, gastrointestinal and inflammatory diseases. This prompted us to design and synthesize azole-based H3R ligands, i.e. having oxadiazole- or thiazole-based core structures. While ligands of oxadiazole scaffold were almost inactive, thiazole-based ligands were very potent and several exhibited binding affinities in a nanomolar concentration range. Ligands combining 4-cyanophenyl moiety as arbitrary region, para-xylene or piperidine carbamoyl linkers, and/or pyrrolidine or piperidine basic heads were found to be the most active within this series of thiazole-based H3R ligands. The most active ligands were in silico screened for ADMET properties and drug-likeness. They fulfilled Lipinski’s and Veber’s rules and exhibited potential activities for oral administration, blood?brain barrier penetration, low hepatotoxicity, combined with an overall good toxicity profile.

Design, synthesis and biological evaluation of anthranilamide derivatives as potent SMO inhibitors

A series of anthranilamide derivatives were designed and synthesized as novel smoothened (SMO) inhibitors based on the SMO inhibitor taladegib (LY2940680), which can also inhibit the SMO-D473H mutant, via a ring-opening strategy. The phthalazine core in LY2940680 was replaced with anthranilamide, which retained the inhibitory activity towards the hedgehog (Hh) signaling pathway as evidenced by a dual luciferase reporter gene assay. Compound 12a displayed the best inhibitory activity against the Hh signaling pathway with IC50 value of 34.09 nM, and exhibited better proliferation inhibitory activity towards the Daoy cell line (IC50 = 0.48 muM) than LY2940680 (IC50 = 0.79 muM).

Design and development of benzoxazole derivatives with toll-like receptor 9 antagonism

Toll-like receptor 9 (TLR9) is a major therapeutic target for numerous inflammatory disorders. Development of small molecule inhibitors for TLR9 remains largely empirical due to lack of structural understanding of potential TLR9 antagonism by small molecules and due to the unusual topology of the ligand binding surface of the receptor. To develop a structural model for rational design of small molecule TLR9 antagonists, an enhanced homology model of human TLR9 (hTLR9) was constructed. Binding mode analysis of a series of molecules having characteristic molecular geometry, flexibility and basicity was conducted based on crystal structure of the inhibitory DNA (iDNA) bound to horse and bovine TLR9. Interaction with specific amino acid residues in four leucine rich repeat (LRR) regions of TLR9 was identified to be critical for antagonism by small molecules. The biological validation of TLR9 antagonism and its correlation with probe-receptor interactions led to a reliable model that could be used for development of novel small molecules with potent TLR9 antagonism (IC50 30?100?nM) with excellent selectivity against TLR7.
