Discovery of 6′-chloro-N-methyl-5’-(phenylsulfonamido)-[3,3′-bipyridine]-5-carboxamide (CHMFL-PI4K-127) as a novel Plasmodium falciparum PI(4)K inhibitor with potent antimalarial activity against both blood and liver stages of Plasmodium
摘要:
Starting from a bipyridine-sulfonamide scaffold, medicinal chemistry optimization leads to the discovery of a novel Plasmodium falciparum PI4K kinase (PfPI4K) inhibitor compound 15g (CHMFL-PI4K-127, IC50: 0.9 nM), which exhibits potent activity against 3D7 Plasmodium falciparum (P. falciparum) (EC50: 25.1 nM). CHMFL-PI4K-127 displays high selectivity against PfPI4K over human lipid and protein kinase. In addition, it exhibits EC50 values of 23-47 nM against a panel of the drug-resistant strains of P. falciparum. In vivo, the inhibitor demonstrates the favorable pharmacokinetic properties in both rats and mice. Furthermore, oral administration of CHMFL-PI4K-127 exhibits the antimalaria efficacy in both blood stage (80 mg/kg) and liver stage (1 mg/kg) of Plasmodium in infected rodent model. The results suggest that CHMFL-PI4K-127 might be a new potential drug candidate for malaria. (C) 2019 Elsevier Masson SAS. All rights reserved.

Invented is a method of inhibiting the activity/function of PI3 kinases using pyridosulfonamide derivatives. Also invented is a method of treating one or more disease states selected from: autoimmune disorders, inflammatory diseases, cardiovascular diseases, neurodegenerative diseases, allergy, asthma, pancreatitis, multiorgan failure, kidney diseases, platelet aggregation, cancer, sperm motility, transplantation rejection, graft rejection and lung injuries by the administration of pyridosulfonamide derivatives.
