Lobetyol
Lobetyol is a natural compound that can be isolated from Lobelia chinensis. Lobetyol induces apoptosis and cell cycle arrest in MKN45 cells. Lobetyol shows anti-virus, anti-inflammation and anti-tumor activity. Lobetyol is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

Lobetyol (0-100 μg/mL, 0-48 h) leads to a dose-and time-dependent proliferation inhibition in MKN45 cells[1].
Lobetyol (0-100 μg/mL, 48 h) induces apoptosis and cell cycle arrest in a time- and dose-dependent manner in MKN45 cells[1].
Lobetyol (0-100 μg/mL, 48 h) increases the expression level of Bax, P53, and decreased the expression level of Bcl-2[1].

Cell Line:MKN45 cells
-
Concentration:0 μg/mL, 50 μg/mL, 75 μg/mL, 100 μg/mL
-
Incubation Time:12 h, 24 h, 48 h
-
Result:Showed a dose-and time-dependent proliferation inhibition in MKN45 cells, with an IC50 of 71.47 ± 4.29 μg/mL at 48 h. Exhibited more safety on L02 and HEK293 human normal cell lines.

Incubation Time:48 h
-
Result:Increased the apoptotic population in MKN45 cells in a dose-dependent manner. Flow cytometic assay of Annexin-V/PI revealed apoptotic populations under increasing dose of lobetyol ranging from 0 μg/mL, 50 μg/mL, 75 μg/mL, to 100 μg/mL are 5.5%, 13.74%, 27.32% to 31.57%, respectively.

Incubation Time:12 h, 24 h, 48 h
-
Result:Increased the expression level of Bax, P53, and decreased the expression level of Bcl-2. The release of cytochrome c was detected, followed by caspase-9 and -3 activations.

Animal Model:BALB/C nude mice (6 weeks-old, injected intraperitoneally with MKN45 cells)[1]
-
Dosage:0, 2, 5, 10 mg/kg
-
Administration:Once per 3 days
-
Result:Suppressed tumor growth in MKN45 nude models. The protein levels of Ki67 in MKN45 cells were significantly decreased. Meanwhile, cleaved-caspase-3 positive MKN45 cells were found increased with the tendency of lobetyol concentrations in the study in vivo.
