Biological Activities

Compounds

Conditions

Thunbergia alata demonstrates significant therapeutic potential in treating renal injury induced by the administration of diclofenac. Research indicates that the secondary metabolites found within its flowers act as a natural defense against the nephrotoxicity caused by this drug. When compared to the diclofenac-control group, the flower extracts show a clear improvement in various kidney parameters and tissue contents. This protective effect is supported by histopathological examinations and the regulation of specific markers such as VEGF, Nrf2, and TGF-β1. Molecular docking studies further suggest that the identified compounds interact effectively with key inflammatory and growth factor proteins to mitigate damage.

Preparations

Parts used

Thunbergia alata contains specialized floral structures that serve as a rich source of bioactive secondary metabolites. Research indicates that the flowers of this species possess significant therapeutic properties capable of combating renal injury. By utilizing high-resolution mass spectrometry, scientists have identified eighteen distinct compounds within these floral extracts. These specific components work to mitigate the nephrotoxicity typically caused by drugs such as diclofenac. Ultimately, the study demonstrates that the flower extracts provide essential protection for kidney tissues through complex molecular pathways.
