LZ1 peptide
LZ1 peptide acts as a Pyruvate kinase inhibitor, antimicrobial agent, and antimalarial agent. LZ1 peptide reduces ATP production and inhibits the malaria parasite Plasmodium falciparum. LZ1 peptide exhibits activity against Plasmodium berghei in mice and reduces parasitemia. LZ1 peptide shows favorable antimicrobial activity against pathogens associated with acne vulgaris. LZ1 peptide possesses anti-inflammatory effects. LZ1 peptide can be used in malaria-related research.

Animal Model:Kunming mice (male, 8 weeks old, intravenous inoculation of 1.0×106 Plasmodium berghei ANKA-infected erythrocytes)[1]
-
Dosage:4-12 mg/kg (4-day suppression test); 4-12 mg/kg (Rane’s test)
-
Administration:i.v.; daily; 4 days (4-day suppression test); i.v.; daily; 4 days (day 3 to day 6, Rane’s test)
-
Result:Reduced parasitemia to 39% (4 mg/kg), 35% (8 mg/kg), and 24% (12 mg/kg) on day 4 compared to 49% in vehicle group.
Slowed parasitemia growth rate in a dose-dependent manner relative to vehicle group.
Prolonged mouse survival in a dose-dependent manner, with higher doses maintaining survival longer than vehicle group.
Reduced serum IL-6 from ~26 pg/mL to ~10 pg/mL, TNF-α from ~145 pg/mL to ~75 pg/mL, and IFN-γ from ~34 pg/mL to ~15 pg/mL at 12 mg/kg while maintaining serum IL-10 at ~145 pg/mL.
Reduced serum ALT from ~55 µM to ~42 µM, AST from ~400 µM to ~250 µM, and total bilirubin from ~7 µM to ~4 µM at 12 mg/kg relative to vehicle-infected mice.
