A quaternary benzo[c]phenanthridine alkaloid chelerythrine displays a wide range of biological activities including cytotoxicity to normal and cancer cells. In contrast, less is known about the biological activity of dihydrochelerythrine, a product of chelerythrine reduction. We examined the cytotoxicity of chelerythrine and dihydrochelerythrine in human promyelocytic leukemia HL-60 cells. After 4h of treatment, chelerythrine induced a dose-dependent decrease in the cell viability with IC50 of 2.6 microM as shown by MTT reduction assay. Dihydrochelerythrine appeared to be less cytotoxic since the viability of cells exposed to 20 microM dihydrochelerythrine for 24h was reduced only to 53%. Decrease in the viability induced by both alkaloids was accompanied by apoptotic events including the dissipation of mitochondrial membrane potential, activation of caspase-9 and -3, and appearance of cells with sub-G1 DNA. Moreover, chelerythrine, but not dihydrochelerythrine, elevated the activity of caspase-8. A dose-dependent induction of apoptosis and necrosis by chelerythrine and dihydrochelerythrine was confirmed by annexin V/propidium iodide dual staining flow cytometry. Besides, both alkaloids were found to induce accumulation of HL-60 cells in G1 phase of the cell cycle. We conclude that both chelerythrine and dihydrochelerythrine affect cell cycle distribution, activate mitochondrial apoptotic pathway, and induce apoptosis and necrosis in HL-60 cells[2].

| ln Vivo |
The antifungal activities of dihydrosanguinarine and dihydrochelerythrine, isolated from the leaves of Macleaya microcarpa, were evaluated on 12 plant pathogenic fungi; the two compounds exhibited the highest antifungal activity against Botrytis cinerea Pers. Among the 11 tested plant pathogenic fungi in vitro, the two compounds showed the highest antifungal activity against B. cinerea Pers, with 95.16% and 98.32% mycelial growth inhibition at 50 µg mL⁻¹, respectively. In addition, the two compounds inhibited spore germination in vitro in a concentration-dependent manner. They also showed potent protective and curative effects against Erysiphe graminis and B. cinerea in vivo. This is the first report on the antifungal activity of dihydrosanguinarine and dihydrochelerythrine against pathogenic plant fungi[1].

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.
