| ln Vitro |
PAD4-IN-4 showed strong inhibitory activity against PAD2 and PAD4 (IC50=2.97±0.29 μM and 0.79±0.09 μM), and had the highest selectivity for PAD4 (3.8 μM)[1]. PAD4-IN-4 significantly inhibited the proliferation of TNBC cells in vitro (4T1 IC50:2.39±0.54 μM; MDA-MB468 IC50: 2.34±0.23 μM), and had relatively low toxicity to normal breast cells (MCF-10A IC50: 8.39±0.60 μM)[1]. PAD4-IN-4 (0.5, 1, 2 μM; 48 h) had enhanced anti-metastatic activity against TNBC cells[1]. PAD4-IN-4 (0.5, 1, 2 μM; 48 h) is a potent PAD4 inhibitor that blocks histone citrullination and neutrophil extracellular trap (NET) formation[1]. Cell Proliferation Assay[1] Cell Line: TNBC cells Concentration: 0.5, 1, 2 μM Incubation Time: 48 h Result: Reduced the number of metastatic cells and wound closure rate less than that of 7 at the equivalent dose, indicating that compound 28 had enhanced antimetastasis activity.

| ln Vivo |
PAD4-IN-4 (1, 5, 10 mg/kg; iv.; once every 2 days for a total of 9 times) can inhibit TNBC lung metastasis in a dose-dependent manner and is a highly active compound against TNBC without obvious toxicity in BALB/c mice with an orthotopic 4T1-luc xenograft model [1]. PAD4-IN-4 changes the tumor microenvironment from a suppressive state to an anti-tumor environment by regulating the proportion of immune cells and reshaping the phenotype and function of neutrophils [1].

Animal/Disease Models:orthotopic 4T1-luc xenograft model in BALB/c mice[1].
Doses: 1, 5, 10 mg/kg Route of Administration: Intravenous injection (i.v.) Experimental Results: The tumor growth inhibition of the high-dose 28-treated group was 61.8%, whereas the positive control doxorubicin hydrochloride group reached 54.6%. Had no significant differences in viscero−somatic ratio and serum biochemical indices (ALT, AST, UREA, and CREA-S) were observed in the 28-treated group. Increased the proportion of mature TANs MHC-II+ TANs whereas it suppressed the proportion of pro-tumor phenotypes PD-L1+ /MHC-II+ TANs and MHC-II− TANs. |

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.
(2) Be sure to add the solvent(s) in order.
