ACHN-975 has an IC50 of 0.02 nM and is directed against Enterobacteriaceae[1]. MIC90 values for ACHN-975 against Enterobacter, Pa, and Ab are 1, 0.5, and >64 μg/mL, respectively [1]. With a minimum inhibitory concentration (MIC) of less than 2 μg/ml, ACHN-975 demonstrated efficacy against all tested isolates of Pseudomonas aeruginosa. In relation to Pseudomonas aeruginosa, its MIC50 and MIC90 are, respectively, 0.06 and 0.25 μg/ml[2]. Targeting six strains of Pseudomonas aeruginosa, ACHN-975's minimum inhibitory concentrations (MIC) against APAE1064, APAE1232, and APAE1064 isolates are 0.12, 0.06, and 0.06 μg/ml, respectively [2]. The first crucial step in the manufacture of lipid A is catalyzed by LpxC, a highly conserved protein in Gram-negative bacteria. Zinc-dependent metalloamidase UDP-3-O-[(R)-3-hydroxymyristoyl]-N-acetylglucosamine deacetylase is the bacterial enzyme known as LpxC [1].

Throughout the first four hours of therapy, bacterial titers steadily decreased in all dosage groups in response to ACHN-975 (ip; 5-30 mg/kg; single dose). The results of the sampling indicated that, two hours after treatment with the 10 mg/kg dose and four hours after treatment with the 30 mg/kg dose, the free drug levels in this model fell below the ACHN-975 MIC (0.25 μg/ml) for this isolate[2].

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

Oral Formulation 3: Dissolved in PEG400 (Please use freshly prepared in vivo formulations for optimal results.) |
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
