LIQ1 (100 μM; 2 h) significantly enhanced the thermal stability of PKM2 in the temperature range of 40-52 °C, increasing its melting temperature (Tm) by 3.4 °C[1]. Compared with wild-type PKM2 (IC50 = 0.98 μM; Kd = 3.2 μM), LIQ1 significantly reduced the inhibitory effect on PKM2 R43A (IC50 = 4.10 μM; Kd = 11.1 μM), indicating that R43 is a key residue mediating allosteric inhibition of PKM2[1].

LIQ1 (1, 2, and 5 mg/kg; intraperitoneal injection; administered 0, 12, 24, and 36 hours after LPS injection) significantly improved the anaphylaxis rate of LPS-induced endotoxin and reduced pathogen and organ damage [1]. LIQ1 (20 mg/kg; intraperitoneal injection; single injection; or once daily for 14 days) showed negligible acute toxicity and no hepatotoxicity or nephrotoxicity in mice, supporting its good safety profile [1].

| Animal Protocol |
Animal/Disease Models: Male BALB/c mice (6-8 weeks old) intraperitoneally injected with LPS (13 mg/kg)[1]
Doses: 1, 2, 5 mg/kg Route of Administration: i.p.; administered at 0, 12, 24, and 36 h after LPS injection Experimental Results: Increased the 7-day survival rate from 40% (1 mg/kg) to 80% (5 mg/kg). Exhibited a dose-dependent reduction in serum IL-1β levels. Mitigated the injuries induced by LPS, such as microvilli loss, villus atrophy, deformation, and necrosis. Alleviated the LPS-induced pathological lesions in the lung and heart tissues at the dose of 5 mg/kg. Suppressed LPS-induced ATP accumulation. Significantly inhibited the nuclear translocation of PKM2 in the small intestine, lung, and heart tissues. Prevented PKM2-HIF-1α complex formation, ultimately leading to reduced IL-1β transcription in mice. Animal/Disease Models: Male BALB/c mice (6-8 weeks old)[1] Doses: 20 mg/kg Route of Administration: i.p.; single dose Experimental Results: Showed no significant decrease in body weight over 14 days. Revealed no changes in motor activity, grooming and rubbing behaviors. Animal/Disease Models: Male BALB/c mice (6-8 weeks old)[1] Doses: 20 mg/kg Route of Administration: i.p.; daily for 14 days Experimental Results: Revealed a significant increase in alkaline phosphatase (ALP) levels. Showed no statistically significant changes in other liver enzymes, including AST, ALT, GGT, total protein (TP), albumin (ALB), and globulin (GLO). Showed no significant effects on kidney function parameters, including urea, creatinine (CREA), uric acid (UA), and estimated glomerular filtration rate (eGFR). |

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.
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.
