w2 p. falciparum

SARS-CoV-IN-1 is an effective SARS-CoV replication inhibitor with an EC50 of 4.9 μM in Vero cells.

SARS-CoV-IN-2 is an effective inhibitor of SARS-CoV replication.

SARS-CoV-IN-3 is an effective inhibitor of SARS-CoV replication.

Arterolane is an antimalarial compound. For against P. falciparum Ro73 and W2, the IC50s are both 1.1 nM.

Antiparasitic agent-22 (Compound 24) is a broad-spectrum antiparasitic compound that inhibits the procyclic form of T. brucei, L. infantum, and L. tropica with IC50 values of 2.41, 5.95, and 8.98 μM, respectively, and the amastigote form of L. infantum with an IC50 of 8.18 μM. It also shows inhibitory activity against the P. falciparum W2 strain with an IC50 of 0.155 μM. Additionally, Antiparasitic agent-22 exhibits low cytotoxicity in THP1 cells, with a CC50 of 64.16 μM.

Keenamide A, a cytotoxic cyclic hexapeptide, exhibits significant activity towards the P-388, A-549, MEL-20, and HT-29 tumor cell lines, but was inactive against the D6 and W2 Plasmodium falciparum malarial clones.

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

Purfalcamine is an orally active, selective Plasmodium falciparum calcium-dependent protein kinase 1 (PfCDPK1) inhibitor with an IC50 of 17 nM and an EC50 of 230 nM, exhibiting antimalarial activity by inducing developmental arrest of malaria parasites at the schizont stage[1][2].

Compound 24 (Compound 7), an in vitro antimalarial agent, demonstrates inhibitory activity against the Plasmodium falciparum W2 strain with an IC50 of 0.81 μM and exhibits a cytotoxicity threshold (CC50) exceeding 200 μM in HepG2 cells [1].

Antileishmanial agent-2 is a 3-Br-isoxazoline-Based Inhibitors against Plasmodium falciparum (D10 and W2 strains) and Leishmania spp. (L. infantum and L. tropica) Promastigotes with IC50s of 0.035, 0.058, 3.5 and 7.5 μM.
