Through activation of G-protein-coupled cell surface C5aR, the complement activation product C5a is known to attract and activate microglia and astrocytes in vitro. The MTT technique 24-hour plate revealed substantial differences between each group and the negative control group. Values were reported for the EP54 group between 0.02724 and 0.1748, the PMX 205 (PMX205) group between 0.09893 and 0.2465, and the tamoxifen group between 0.09880 and 0.2464. Only two groups—PMX 205 and Tamoxifen—showed significant outcomes for the 48-hour incubation time plates. The values that were recorded varied from 0.5777 to 0.8551 and 0.04987 to 0.3273, respectively. Only one group—the antagonist group, PMX 205—showed significant results on the 72-hour plates; its values ranged from 0.02136 to 0.5322 [1].

PMX 205, sometimes known as PMX205, is a selective and active oral C5aR antagonist. When compared to rats given with a vehicle, animals treated with PMX 205 (1 mg/kg/day, p.o.) exhibited significantly longer survival times and lower terminal motor scores. In the lumbar spinal cord, mice treated with PMX 205 also displayed decreased levels of astrocyte growth. Oral administration of PMX 205 (1 mg/kg/day) was administered to SOD1G93A rats twice, on day 28 and day 70, prior to the development of significant clinical signs. There was no discernible difference in the survival times between the two treatment regimens [2], with both treatment groups showing considerably longer survival times than untreated rats (p=0.022, day 28; p=0.015, day 70). Between the ages of 12 and 15 months (n = 17), Tg2576 mice were given a 20 μg/mL dose of PMX 205 (PMX205) in their drinking water, at which time their amyloid deposits were rapidly accumulating. inside the range. Eleven untreated Tg2576 animals served as the controls. Compared to untreated animals, PMX 205-treated animals had a notably lower fibrous plaque burden (thioflavin response) after three months. In 3×Tg mice, PMX 205 likewise markedly decreased hyperphosphorylated tau (69%) [3].

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).

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
