AN3661, a potent antimalarial lead compound, targets a Plasmodium falciparum cleavage and polyadenylation specificity factor homologue subunit 3 (PfCPSF3). AN3661 inhibits Plasmodium falciparum laboratory-adapted strains (mean IC50=32 nM), Ugandan field isolates (mean ex vivo IC50=64 nM), and murine P. berghei and P. falciparum infections.

Description

AN3661, a potent antimalarial lead compound, targets a Plasmodium falciparum cleavage and polyadenylation specificity factor homologue subunit 3 (PfCPSF3). AN3661 inhibits Plasmodium falciparum laboratory-adapted strains (mean IC50=32 nM), Ugandan field isolates (mean ex vivo IC50=64 nM), and murine P. berghei and P. falciparum infections[1].

In Vitro

AN3661 is active at nanomolar (IC50=20-56 nM) concentrations against P. falciparum laboratory strains known to be sensitive (3D7) or resistant (W2, Dd2, K1, HB3, FCR3 and TM90C2B), and AN3661 is similarly active in ex vivo studies of fresh Ugandan field isolates (mean ex vivo IC50=64 nM). AN3661 shows minimal cytotoxicity against mammalian cell lines, with the CC50 60.5 μM against Jurkat cells, and all other CC50 values greater than the highest concentrations tested (25 μM or above)[1].
AN3661 inhibits the stability of P. falciparum transcripts[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

AN3661 (50-200 mg.kg; p.o.; daily for 4 days) inhibits murine P. berghei infections with ED90 (4 days) 0.34 mg/kg[1].
AN3661 is administered orally for 4 days, beginning on the third day of infection, the ED90 4 days after initiation of treatment is 0.57 mg/kg[1].

Animal Model: P. berghei-infected mice (malaria model)[1]
Dosage: 50, 100, 200 mg/kg
Administration: Orally; daily for 4 days
Result: Rapidly controlled parasitemias, with an ED90 of 0.34 mg/kg. Daily dosages of 50 mg/kg and 100 mg/kg extended survival, and mice treated with 200 mg/kg per day demonstrated long-term cures.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.08 mg/mL (10.10 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.08 mg/mL (10.10 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
