UCT943 is a next-generation Plasmodium falciparum PI4K inhibitor. UCT943 inhibits the P. vivax PI4K (PvPI4K) enzyme with an IC50 of 23 nM[1].
UCT943 maintains high in vitro selectivity (>200-fold) for the parasite PvPI4K versus the human PI4Kβ isozyme (IC50 of PI4Kβ, 5.4 μM), inhibition of which is linked to immunosuppressive effects[1]. In vitro cytotoxicity of UCT943 is tested against L6 cells, chinese hamster ovarian (CHO), Vero, and HepG2 cells, with 50% cytotoxic concentrations (CC50s) of 12, 17, 113, and 13 μM, respectively[1].
UCT943 shows excellent in vivo efficacy in the Plasmodium berghei (10 mg/kg and 3 mg/kg; oral administration; daily; 4 days) and P. falciparum NSG (NOD-scid IL-2Rγnull) mouse models (0.01, 0.1, 0.3, 1.1 and 10 mg/kg; oral administration; once per day; 4 days). When dosed at 10 mg/kg per os (p.o.), UCT943 reduces parasitemia by >99.9% in the mouse P. berghei infection model and cures all mice, with >30 mean survival days (MSD). At 3 mg/kg p.o., no complete cure is achieved, and MSD is 10 days, albeit parasitemia is reduced by 99%. The resulting 90% effective dose (ED90) is 1.0 mg/kg p.o. in the P. berghei infection model. The ED90 is 0.25 mg/kg in the P. falciparum-infected NSG mouse model[1].

UCT943, a Next-Generation Plasmodium falciparum PI4K Inhibitor Preclinical Candidate for the Treatment of Malaria
Antimicrob Agents Chemother 2018 Aug 27;62(9):e00012-18.PMID:29941635DOI:10.1128/AAC.00012-18.
The 2-aminopyridine MMV048 was the first drug candidate inhibiting Plasmodium phosphatidylinositol 4-kinase (PI4K), a novel drug target for malaria, to enter clinical development. In an effort to identify the next generation of PI4K inhibitors, the series was optimized to improve properties such as solubility and antiplasmodial potency across the parasite life cycle, leading to the 2-aminopyrazine UCT943. The compound displayed higher asexual blood stage, transmission-blocking, and liver stage activities than MMV048 and was more potent against resistant Plasmodium falciparum and Plasmodium vivax clinical isolates. Excellent in vitro antiplasmodial activity translated into high efficacy in Plasmodium berghei and humanized P. falciparum NOD-scid IL-2Rγ null mouse models. The high passive permeability and high aqueous solubility of UCT943, combined with low to moderate in vivo intrinsic clearance, resulted in sustained exposure and high bioavailability in preclinical species. In addition, the predicted human dose for a curative single administration using monkey and dog pharmacokinetics was low, ranging from 50 to 80 mg. As a next-generation Plasmodium PI4K inhibitor, UCT943, based on the combined preclinical data, has the potential to form part of a single-exposure radical cure and prophylaxis (SERCaP) to treat, prevent, and block the transmission of malaria.
