anti-protozoal

Diloxanide (RD3803) is an endomoeba insecticide. It is considered to be the luminal agent of choice for patients with mild enteroamoebiasis or asymptomatic cysts.

Chlorophorin shows high anti-protozoal activity with an MIC of 0.25 microg/ml. Chlorophorin can strongly inhibit mushroom tyrosinase activity with IC50 values of 2.5 ± 0.408 uM; it inhibits α-melanocyte-stimulating hormone-induced melanin production in B16F10 melanoma cells.

Quinacrine is a compound that is commonly used as an anti-protozoal agent. It inhibits voltage-dependent sodium channels (IC50: 3.3 μM） and suppresses aldehyde oxidase (IC50: 3.3 μM). Quinacrine prevents misfolding of prion protein (EC50: 0.3 μM). As an e

Quinacrine is a compound with multiple actions that is commonly used as an anti-protozoal agent. It has also been shown to be a highly potent autophagy inhibitor, although the dose required to achieve this effect is considerably cytotoxic (LD50 = 2.5 μM). Quinacrine analog 34 is a derivative of quinacrine that was designed with an improved cell viability profile (LD50 = 27 μM) to inhibit autophagy. At a minimum concentration of 0.5 μM, this compound has been shown to increase the protein levels of the autophagy biomarker LC3-II and to induce lysosome deacidification.

Pinafide is a rodenticide and anti-protozoal agent. Pinafide shows strong cytostatic activity against both HeLa and KB cells and is moderately toxic to both mice and rats. It has been proved active against experimental tumors and shown to be inhibitor of two DNA viruses. Pinafide blocks cell growth by inhibiting DNA and RNA synthesis. It has been shown to bind to double-helical DNA by intercalation. Pinafide inhibited the activity of M. tuberculosis NAD⁺-dependent DNA ligase A at concentrations of 50 uM. At the chemical screening was found that pinafide inhibited B-Myb transcriptional activity in luciferase assays. The cross placental-barrier studies showed that 3H-pinafide was present in the 14-day fetuses.

Xenopsin precursor fragment, an antimicrobial peptide, exhibits both antibacterial/antifungal activity at concentrations ranging from 10 to 500 μg/mL and anti-protozoal activity with a minimum inhibitory concentration (MIC) of 2 to 20 μg/mL [1].

Teclozan is an antiprotozoal agent of the benzylamine derivative class. teclozan exhibits anti-G. intestinalis effects in the intestinal lumen, interferes with phospholipid metabolism and prevents the formation of arachidonic acid. teclozan can be used to study protozoal infections.
