SPR206 acetate Chemical Properties,Usage,Production

Uses

SPR206 acetate is a polymyxin analog with antibiotic activity against Gram-negative pathogens, including multidrug-resistant (MDR) variants. SPR206 acetate has an anti-bacterial infection effect by interacting with the bacterium’s outer membrane. The MIC values of SPR206 acetate against Pseudomonas aeruginosa Pa14 and Acinetobacter baumannii NCTC13301 are both 0.125 mg/L[1][2].

in vivo

SPR206 (0.125-30 mg/kg; intravenous injection or subcutaneous injection; every 8 hours or every 4 hours; for 16 hours or 24 hours; neutropenic mice) treatment reduces the burden of Pa14 and NCTC13301 in lung tissue and in the thigh model^[2].

Animal Model:	Neutropenic mice infected Pa14 or NCTC13301^[2]
Dosage:	3 mg/kg, 10 mg/kg, 20 mg/kg, 30 mg/kg (intravenous injection); 0.125 mg/kg, 0.5 mg/kg, 1 mg/kg, 4 mg/kg (subcutaneous injection)
Administration:	Intravenous injection or subcutaneous injection; every 8 hours or every 4 hours; for 16 hours or 24 hours
Result:	In lung tissue, reduced the burden of Pa14 and NCTC13301 by 1.5 and 3.6 log₁₀ CFU/mL. In the thigh model, reduced the burden of Ab13301 by 3.4 and 4.3 log₁₀ CFU/g.
