IC50: Heme oxygenase-1 (HO-1)
Tin-protoporphyrin IX (SnPPIX)(20 μM, 50 μM; 24 hours) significantly suppressed the proliferation of Capan-1 and CD18/HPAF cells. In contrast, SnPPIX has no significant effect on PDAC cells proliferation at all exposures except at 50 μM.
Cell Viability Assay
| Cell Line: | Capan-1, CD18/HPAF, PDAC cells |
| Concentration: | 20 μM, 50 μM |
| Incubation Time: | 24 or 72 hours |
| Result: | Inhibited Capan-1 and CD18/HPAF cells proliferation and inhibits PDAC cells growth at 50μM. |
Tin-protoporphyrin IX (SnPPIX)(intraperitoneal injection; 5 mg/kg; at 0, 7, 15, and 20 days) alone or combines with Gemcitabine significantly reduced the weight of pancreatic tumors (P < 0.05), decreases metastasis and improved the efficacy of Gemcitabine treatment.
| Animal Model: | Male and female athymic nude mice with PDAC cell-derived xenograft tumors |
| Dosage: | 5 mg/kg |
| Administration: | Intraperitoneal injection; at days 1, 4, 6, 8, 11, 13, 15, 18, and 20 |
| Result: | Inhibited tumor growth and sensitized tumors to chemotherapy (Gemcitabine). |
