Ppc-1 is an anti-obesity agent. It shows mitochondrial uncoupling activity in vitro and anti-obesity activity in vivo. Ppc-1 is also an inhibitor of interleukin-2 (IL2) production in Jurkat cells. | [Uses]
Ppc-1 is a mitochondrial uncoupler. Ppc-1 enhances mitochondrial oxygen consumption without adverse effects on ATP production. Ppc-1 is a cell-permeate interleukin-2 (IL-2) inhibitor. Ppc-1 inhibits the Gram-negative periodontopathogen Porphyromonas gingivalis. Ppc-1 has anti-obesity, antibacterial and anti-inflammatory activities[1][2][3][4]. | [in vivo]
Ppc-1 (0-10 mg /kg; Intraperitoneal injection; once a week; for 8 weeks; female ICR mice) treatment suppresses weight gain with no abnormal effects on liver or kidney tissues, and no evidence of tumor formation[1].
Serum fatty acid levels are significantly elevated in mice treated with Ppc-1, while body fat content remained low. After a single administration, Ppc-1 distributes into various tissues of individual animals at low levels. Ppc-1 stimulates adipocytes in culture to release fatty acids, which might explain the elevated serum fatty acids in Ppc-1-treated mice[1]. | Animal Model: | Female ICR mice[1] | | Dosage: | 0 mg /kg , 0.16 mg /kg, 0.8 mg /kg, 4 mg /kg, and 10 mg /kg | | Administration: | Intraperitoneal injection; once a week; for 8 weeks | | Result: | Suppresseed weight gain in animals.
