Vacuolar H+-ATPase (v-ATPase) subunit ATP6V1G [3]. With an IC50 of 388 nM, verucopeptin (0-30 μM; 72 h) had remarkable anticancer efficacy against K562R cells; nevertheless, these cells exhibited resistance to some other chemotherapeutic drugs, including vincristine at 10 μM and paclitaxel. therapeutic qualities [3]. With IC50 values less than 100 nM, verucopeptin (0-1 μM) exhibits wide antiproliferative action against 66% of the 1,094 cancer cell lines examined. Moreover, verucopeptin is categorized into the lower IC50 group, which includes leukemia, lymphoma, and melanoma, and the higher IC50 group, which includes non-small cell lung cancer and other cancer types [3]. Verucopeptin (10 nM; 1 hour) pretreatment prevented VE-P labeling of ATP6V1G1 in competitive binding tests, but not ATP1V1B2 or ATP6V1D. Verucopeptin and Baf A1, albeit to a lesser degree, both significantly reduce lysosomal acidification and v-ATPase activity in vitro [3]. At doses of 10-200 nM, verucopeptin (0-500 nM; 1 hour) strongly suppresses p-S6K and p-4EBP1. Furthermore, at dosages ranging from 50 nM to 500 nM, verucopeptin inhibited the phosphorylation of the majority of examined mTORC1 downstream substrates, including p-4EBP1, pmTORS2448, p-mTORS2481, p-Rictor, p-ULK1, and p-Grb10 [3]. Verucopeptin (0-335 nM; 24 hours) did not affect c-Raf in HT1080 cells, but it did decrease HIF-1 protein levels in a dose-dependent manner. On the other hand, HIF-1 and c-Raf production in cells is inhibited by the well-known hsp90 inhibitor tantespimycin [2].

| ln Vivo |
Verucopeptin (IV; 1 mg/kg; twice daily; 7 days) effectively reduced tumor growth without significant weight loss or clear evidence of toxicity. HE staining demonstrated that Verucopeptin successfully promoted cell death and abolished mTORC1 signaling through dephosphorylation of S6K and 4EBP1 [3].

| Animal Protocol |
Animal/Disease Models: BALB/c nude mice were injected subcutaneously (sc) (sc) with SGC7901/VCR cells [3].
Doses: 1 mg/kg. Route of Administration: intravenous (iv) (iv)injection; subcutaneous injection of SGC7901/VCR cells. 1 mg/kg; twice (two times) daily; 7 days Experimental Results: Demonstrated profound in vivo antitumor efficacy against MDR tumors. |

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).

*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.
