Identifying new chemicals with greater effectiveness, safety than quisinostat

NewsGuard 100/100 Score

Announcing a new review article publication for Acta Materia Medica journal. In this article the authors use medicinal chemistry methods to identify new chemical entities with greater effectiveness and safety than quisinostat.

In total, 38 novel hydroxamic acid derivatives were designed and synthesized, and their in vitro antimalarial activities were systematically investigated. These compounds at nanomolar concentrations showed inhibitory effects on wild-type and drug-resistant Plasmodium falciparum strains in the erythrocyte stage.

Among them, compound 30, after oral administration, resulted in complete elimination of parasites in mice infected with Plasmodium yoelii, and also exhibited better safety and metabolic properties than observed in our previous work. Mechanistically, compound 30 upregulated plasmodium histone acetylation, according to western blotting, thus suggesting that it exerts antimalarial effects through inhibition of Plasmodium falciparum HDAC enzymes.
