TKK130 is a 3-Hydroxy-Propanamidine (HPA) with Potent Antimalarial In Vivo Activity and a High Barrier to Resistance
Malaria continues to pose a significant burden on populations in endemic areas and requires innovative treatment options. Here, we report the synthesis and preclinical evaluation of the novel 3-hydroxypropanamidine (HPA) 2 (TKK130), which shows excellent antiplasmodial in vitro activity against drug-sensitive and -resistant Plasmodium falciparum strains. Moreover, in various human cell lines, the compound shows no cytotoxicity and excellent parasite selectivity. The compound inhibits synthetic hemozoin (β-hematin) formation, with IC50 values lower than chloroquine (CQ), and its in vitro rate of activity is comparable with the fast-acting antimalarial drug dihydroartemisinin. Furthermore, selection studies reveal a very low propensity for resistance development. Based on initial in vivo pharmacokinetic snapshot data, 2 (TKK130) has a long-lasting, linear pharmacokinetic profile. In vivo, this novel HPA exhibits curative activity in the Plasmodium bergheimouse model and potent activity in theP. falciparum SCID mouse model after oral administration.
期刊介绍:
The Journal of Medicinal Chemistry is a prestigious biweekly peer-reviewed publication that focuses on the multifaceted field of medicinal chemistry. Since its inception in 1959 as the Journal of Medicinal and Pharmaceutical Chemistry, it has evolved to become a cornerstone in the dissemination of research findings related to the design, synthesis, and development of therapeutic agents.
The Journal of Medicinal Chemistry is recognized for its significant impact in the scientific community, as evidenced by its 2022 impact factor of 7.3. This metric reflects the journal's influence and the importance of its content in shaping the future of drug discovery and development. The journal serves as a vital resource for chemists, pharmacologists, and other researchers interested in the molecular mechanisms of drug action and the optimization of therapeutic compounds.
