Quassin (Nigakilactone D) 是一种从 Quassia amara 的茎皮提取物中提取的生物活性三萜。Quassin 抑制 P. falciparum，IC50 为 0.15 μM。Quassin 具有可逆的抗生育能力，抗雌激素和抗疟原虫活性。
IC50: 0.15 μM ( P. falciparum )
Quassin (Compound 1; 5-25 ng/mL) inhibits both the basal and luteinizing hormone-stimulated testosterone secretion of rat Leydig cells in a dose-dependent fashion.
Quassin (0.1-2.0 mg/kg; oral administration; daily; for 60 days; females albino rats) treatment shows a significant decrease in the weight of the ovary and uterus. And also shows a significant decrease in serum estrogen levels in quassin treated rats. The Quassin treated rats has a significantly decreased mean litter number and weight. Quassin does not adversely affect the weight of the kidney, heart, liver and the body of the rats.
| Animal Model: | 35 females albino rats (150-170 g) |
| Dosage: | 0.1 mg/kg, 1.0 mg/kg and 2.0 mg/kg |
| Administration: | Oral administration; daily; for 60 days |
| Result: | There was a significant decrease in the weight of the ovary and uterus in all the groups relative to the control. There was also a significant decrease in serum estrogen levels in quassin treated rats. |
