Description: Pentamidine Isethionate (MP-601205; MP601205) is an antimicrobial and annticancer agent that interferes with DNA biosynthesis. It exhibits antitumor and antibacterial activities by inhibiting protein tyrosine phosphatases (PTPases) and phosphatase of regenerating liver (PRL). It can be potentially used for Gambian trypanosomiasis, antimony-resistant leishmaniasis, and Pneumocystis carinii pneumonia treatment.
| ln Vitro |
Diabetes growth is inhibited in a concentration-regulated manner by pentamidine isethionate (0-10 μg/mL; 6 days; WM9, DU145, C4-2, Hey, WM480, and A549 cells) treatment [1]. It was established how harmful pentamidine isethionate is to promastigotes of the animal parasite Leishmania fanum. Pentamidine ethanesulfonate exhibited 60 times more leishmanicidal activity than cisplatin following a 72-hour period of sterility. The inhibition of DNA synthesis and cell cycle signaling in the G2/M phase is the reason why pentamidine isethionate causes more programmed cell death (PCD) than cisplatin. The calf thymus DNA (CT-DNA) undergoes a conformational change in response to pentamidine isethionate binding that is consistent with the B-->A transition. Pentamidine isethionate is equivalent to ubiquitin and causes a 6% rise in the protein's β-sheet content [2].

| Additional Infomation |
Pentamidine isothiocyanate is an odorless white or nearly white crystal or powder. It has also been reported to have a slightly butyric acid odor. It has an extremely bitter taste. The pH (5% aqueous solution) is 4.5-6.5. (NTP, 1992)
Pentamidine isothiocyanate is an organic sulfonate prepared by reacting Pentamidine with two equivalents of 2-hydroxyethylsulfonic acid. It is a trypanosome-killing agent. It contains pentaneonium(2+) ions. Pentamidine isothiocyanate is a prescription antifungal drug approved by the U.S. Food and Drug Administration (FDA) for the treatment and prevention of Pneumocystis carinii pneumonia (PCP). FDA-approved uses of Pentamidine isothiocyanate depend on its dosage form. Specifically, Pentamidine isothiocyanate injection is approved for the treatment of Pneumocystis carinii pneumonia (PCP), and Pentamidine isothiocyanate inhalation is approved for the prevention of PCP in high-risk populations, especially those infected with HIV. PCP is an opportunistic infection (OI) associated with HIV infection. Pentamidine isothiocyanate is a synthetic amitidine derivative with antiprotozoal and antifungal activity. Its mechanism of action appears to be interaction with the minor groove of AT-rich DNA regions in the pathogen genome, thereby interfering with DNA replication and function. It is effective in treating trypanosomiasis, leishmaniasis, certain fungal infections, and Pneumocystis carinii pneumonia in HIV-infected individuals. (NCI04) An antiprotozoal drug effective against trypanosomiasis, leishmaniasis, and certain fungal infections; used to treat Pneumocystis carinii pneumonia in HIV-infected individuals. It may cause diabetes, central nervous system damage, and other toxic effects. See also: Pentamidine (with the active fraction). |
