| 生物活性 | Pentamidine dihydrochloride (MP-601205 dihydrochloride) is an antimicrobial agent and interferes with DNA biosynthetics. Pentamidine dihydrochloride inhibitsparasiteLeishmaniainfantumwith anIC50of 2.5 μM. Pentamidine dihydrochloride is a potent and selectiveprotein tyrosine phosphatases(PTPases)andphosphataseof regenerating liver (PRL)inhibitor. Pentamidine dihydrochloride has the potential forGambian trypanosomiasis, antimony-resistantleishmaniasis, andPneumocystis cariniipneumonia treatment. Antitumor and antibacterial activities[1][2][3][4]. |

体外研究
(In Vitro) | Pentamidine (0-10 μg/mL; 6 days; WM9, DU145, C4-2, Hey, WM480, and A549 cells) treatment inhibits the growth of cancer cells in a concentration-dependent manner[1].
The cytotoxic properties of Pentamidine isethionate towards the promastigotes of the protozoan parasiteLeishmania infantumis determined. The leishmanicidal activity of Pentamidine isethionate is 60 times higher after 72 h of incubation than that of Cisplatin. Pentamidine isethionate induces a higher amount of programmed cell death (PCD) than Cisplatin, which is associated with inhibition of DNA synthesis and cell-cycle arrest in the G2/M phase. Binding of Pentamidine isethionate to calf-thymus DNA (CT-DNA) induces conformational changes in the DNA double helix, consistent with a B-->A transition. The interaction of Pentamidine isethionate with ubiquitin leads to a 6% increase in the beta-sheet content of the protein[2].
Cell Viability Assay[1] | Cell Line: | WM9, DU145, C4-2, Hey, WM480, and A549 cells | | Concentration: | 0-10 μg/mL | | Incubation Time: | 6 days | | Result: | The growth of all six of the cell lines in culture was inhibited in a concentration-dependent manner with complete growth inhibition of the cell lines occurring at 10 μg/mL. |
