Biological Activities
Leucas calostachys has emerged as a significant species in the pharmacological investigation of traditional medicinal plants from the Greater Mpigi region of Uganda. During recent studies focused on treating malaria and related disorders, researchers identified this plant as a promising candidate for antiprotozoal therapy. Specifically, an ethyl acetate extract of its leaves demonstrated notable antiplasmodial activity against the chloroquine-resistant P. falciparum K1 strain. The study reported an IC50 value of 5.7 µg/ml for this extract, paired with a selectivity index of 2.6. These findings provide essential early-stage support for the therapeutic use of local vegetation in managing malaria infections.
Compounds
Conditions
Leucas calostachys serves as a potent medicinal plant capable of treating inflammation and related disorders. Scientific assessments demonstrate that its ethyl acetate extract is a highly effective COX-2 inhibitor within the PGH2 pathway. Furthermore, this species is utilized for its antiprotozoal properties in the treatment of malaria. Specifically, the ethyl acetate extract of its leaves has exhibited significant antiplasmodial activity against P. falciparum K1. These pharmacological findings provide strong evidence supporting the traditional medicinal uses of the plant.
Preparations
Leucas calostachys is prepared as an ethyl acetate extract for pharmacological evaluation. This specific extract demonstrated significant potency by exhibiting the lowest IC50 value of 0.66 µg/mL in the COX-2 inhibition assay. Furthermore, the ethyl acetate preparation of this plant yielded the most promising selectivity ratio of 0.1 regarding COX-2 versus COX-1 inhibition. These results highlight the effectiveness of utilizing this particular solvent for extracting the medicinal components of the species. Such findings validate the plant's potential as a highly selective anti-inflammatory agent within the studied pathway.
Parts used
