5-Phenoxy Primaquine Analogs and the Tetraoxane Hybrid as Antimalarial Agents. [PDF]
Molecules, 2021 The rapid emergence of drug resistance to the current antimalarial agents has led to the urgent need for the discovery of new and effective compounds. In this work, a series of 5-phenoxy primaquine analogs with 8-aminoquinoline core (7a–7h) was synthesized and investigated for their antimalarial activity against Plasmodium falciparum.
