Introduction of 129297-22-9 :

Kijimicin is a polyether ionophore antibiotic originally discovered in Actinomadura sp. MI215-NF3. inhibits HIV-1 replication and reduces the infectivity of progeny viral particles. Kijimicin exhibits inhibitory activity against intracellular T. gondii (IC50 = 45.6 nM), extracellular parasites (IC50 = 216.6 pM) and C. parvum (IC50 = 7.7 nM), and controls acute T. gondii infection in mice. Kijimicin can be used for research on HIV, toxoplasmosis, cryptosporidiosis, and bacterial infections[1][2][3][4]. In Vitro:Kijimicin (7 days) inhibits HIV-1 replication in acutely infected H9 cells with an IC50 of 2.2 μg/mL, and shows little cytotoxicity (IC50 = 88 μg/mL)[1].
Kijimicin (0.1-1000 μg/mL; 72 h) inhibits HIV-1 replication in chronically infected U937 cells[1].
Kijimicin (0.01, 0.1, 1.0 μg/mL; 7 days) reduces the infectivity of progeny HIV-1 viral particles from H9 cells by more than 1 log[1].
Kijimicin exhibits antimicrobial activity against Gram-positive bacteria including Staphylococcus aureus FDA 209P (MIC < 0.78 μg/mL), Bacillus cereus ATCC 10702 (MIC < 0.78 μg/mL), and Micrococcus luteus PCI 1001 (MIC < 0.78 μg/mL)[2].
Kijimicin (7.7 nM; 48 h) inhibits C. parvum growth in HCT-8 cells with an IC50 of 7.7 nM and a CC50 > 20 μM (selectivity index = 2585)[3].
Kijimicin (1-300 nM; 72 h) inhibits intracellular T. gondii RH-GFP growth in HFF cells with an IC50 of 45.6 nM and a selectivity index of 1019.7[4].
Kijimicin (1-2000 pM; 1 h) inhibits extracellular T. gondii RH-GFP invasion into Vero cells with an IC50 of 216.6 pM and a selectivity index of 214,681.4[4].
Kijimicin (50 nM; 24 h) induces morphological changes in T. gondii tachyzoites, including cell swelling and multiple intracellular vacuole-like structures[4].
In Vivo:Kijimicin (3, 10 mg/kg; i.p.; once daily for 7 days) improves survival and alleviates clinical signs in 6-8-week-old female BALB/c mice infected with T. gondii PLK-GFP. Kijimicin sodium achieves a survival rate of 91.7% at the 10 mg/kg dose, and yields a 66.7% survival rate at the 3 mg/kg dose[4].
