Biological Activities
Compounds
Conditions
Eremophila glabra leaf resin extracts demonstrate significant inhibitory activity against both protein tyrosine phosphatase 1B (PTP1B) and α-glucosidase. The crude extracts specifically target PTP1B with an IC50 value of 11.8 ± 2.1 μg/mL. Furthermore, the plant treats α-glucosidase with an observed IC50 value of 19.3 ± 1.2 μg/mL. Research into these relationships led to the isolation of several serrulatane diterpenoids, such as eremoglabrane A-G, which contribute to these medicinal effects. These specific inhibitory actions highlight the plant's potential as a source for antihyperglycemic drug leads.
Preparations
Parts used
Eremophila glabra is a notable member of the Scrophulariaceae family, consisting of Australian desert plants with a rich history of medicinal use by Aboriginal people. Recent scientific investigations have focused specifically on the chemical properties found within the leaves of this species. Researchers analyzed crude extracts of the leaf resin to identify potent bioactive compounds. This study successfully isolated several undescribed serrulatane diterpenoids, known as eremoglabranes A-G, from the plant material. These leaf-derived compounds demonstrate significant potential as antihyperglycemic drug leads due to their inhibitory activities.
