Quassin BiologicalActivity
| Description | Quassin (Nigakilactone D) is a bioactive triterpenoid from stem bark extract of Quassia amara. Quassin inhibits P. falciparum with an IC50 of 0.15 μM. Quassin possesses reversible antifertility, anti-estrogenic and anti-plasmodial activity[1][2]. |

| Target | IC50: 0.15 μM (P. falciparum)[2] |
|---|
| In Vitro | 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[3]. |
|---|
| In Vivo | 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[1]. Animal Model: 35 females albino rats (150-170 g)[1] 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. |
