ACHN-975 

ACHN-975 is a selective LpxC inhibitor and exhibits a subnanomolar LpxC inhibitory activity. ACHN-975 is against a wide range of gram-negative bacterias with low MIC values (≤1 μg/mL)^[1].

LpxC^[1]

ACHN-975 is against Enterobacteriaceae spp with an IC₅₀ of 0.02 nM^[1].
ACHN-975 is against Enterobacteriaceae spp, Pa, and Ab with MIC90 values of 1, 0.5, and >64 μg/mL, respectively^[1].
ACHN-975 is potently against the P. aeruginosa isolates tested, inhibiting 100% of the isolates at an MIC of ≤2 μg/ml. It against Pseudomonas aeruginosa with an MIC₅₀ and MIC₉₀ of 0.06 and 0.25 μg/ml, respectively^[2].
ACHN-975 is against six P. aeruginosa isolates, it against P. aeruginosa APAE1064, APAE1232, and APAE1064 isolates with MIC values of 0.12, 0.06 and 0.06  μg/ml, respectively^[2].
LpxC is highly conserved in gram-negative bacteria and catalyzes the first committed step of lipid A biosynthesis. LpxC is the bacterial enzyme Zinc-dependent metalloamidase UDP-3-O-[(R)-3-hydroxymyristoyl]-N-acetylglucosamine deacetylase^[1].

ACHN-975 (intraperitoneal administration; 5-30 mg/kg; single dose) leads to a steady reduction in bacterial titers in the first 4 h following treatment for all dosing groups. The sampling shows that the level of free drug in this model drops below the ACHN-975 MIC for this isolate (0.25 μg/ml) by 2 h after treatment with the 10 mg/kg dose and by 4 h after treatment with the 30 mg/kg dose^[2].
