生物活性 | Prodigiosin (Prodigiosine) is a red pigment produced by bacteria as a bioactive secondary metabolite. Prodigiosin is a potent inhibitor of theWnt/β-cateninpathway. Prodigiosin has antibacterial, antifungal, antiprotozoal, antimalarial, immunosuppressive, and anticancer properties[1][2]. |
体外研究 (In Vitro) | Prodigiosin (25-500 nM; 24 hours) treatment reduces the viability of breast cancer cells, with IC50values at 48 h of 62.52 nM in MDA-MB-231 cells and 261.2 nM in MDA-MB-468 cells[1]. Prodigiosin (25-500 nM; 24 hours) treatment significantly reduces the levels of phosphorylated LRP6 and DVL2, active β-catenin, and total β-catenin. Prodigiosin noticeably inhibits the phosphorylation of GSK3β at Ser9 in HEK293T cells, which is indicative of an increase in GSK3β activity[1]. Prodigiosin can inhibit proliferation and induce apoptosis in breast cancer cells[1]. Prodigiosin (25-500 nM; 24 hours) treatment dose-dependently blocks Wnt signaling activated by Wnt1, Wnt3, Wnt1/LRP6, Wnt3/LRP6, and Dishevelled 2 (DVL2) in transfected HEK293T cells. Prodigiosin treatment inhibits Wnt3A-CM-induced transcription in a dose-dependent manner. Prodigiosin inhibits transcription of the SuperTopFlash reporter activated by either Wnt transfection or Wnt3A treatment[1]. When applied to cultures of chytrid fungiBatrachochytrium dendrobatidisandB. salamandrivorans, Prodigiosin causes significant growth inhibition, with MIC values of 10 μM and 50 μM, respectively[2].
Cell Proliferation Assay[1] Cell Line: | MDA-MB-231 and MDA-MB-468 cells | Concentration: | 10 nM, 25 nM, 50 nM, 100 nM, 250 nM, 500 nM, 1000 nM, 2500 nM, 5000 nM | Incubation Time: | 24 hours, 48 hours | Result: | Reduced the viability of breast cancer cells, with IC50values at 48 h of 62.52 nM in MDA-MB-231 cells and 261.2 nM in MDA-MB-468 cells. |
Western Blot Analysis[1] Cell Line: | HEK293T cells | Concentration: | 50 nM, 100 nM, 250 nM, 500 nM | Incubation Time: | 24 hours | Result: | Significantly reduced the levels of phosphorylated LRP6 and DVL2, active β-catenin, and total β-catenin. |

体内研究 (In Vivo) | Prodigiosin (5 mg/kg; intraperitoneal injection; twice weekly; for 3 weeks) treatment significantly inhibits tumor growth. Prodigiosin treatment decreases tumor cell density and expression of the proliferation marker Ki-67[1].
Animal Model: | Female BALB/c nude mice injected with MDA-MB-231 cells[1] | Dosage: | 5 mg/kg | Administration: | Intraperitoneal injection; twice weekly; for 3 weeks | Result: | Significantly inhibited tumor growth in mice. |
