Abstract
Sinensetin, a prominent flavone from Orthosiphon stamineus is a promising constituent for anti-rheumatoid arthritis. This study evaluated the oral anti-inflammatory and anti-angiogenic efficacy of sinensetin. In carrageenan-induced arthritic mice, oral sinensetin (25-100 mg/kg) significantly reduced paw edema with dose-correlated plasma kinetics, confirming functional oral bioavailability despite a delayed onset compared to intraperitoneal administration. Ex vivo rat aortic ring and in vitro human endothelial assays revealed that sinensetin robustly suppressed microvessel outgrowth and cell migration via VEGF downregulation. These findings demonstrate that sinensetin is an orally bioavailable agent capable of suppressing inflammation and angiogenesis.
期刊介绍:
The Journal of Asian Natural Products Research (JANPR) publishes chemical and pharmaceutical studies in the English language in the field of natural product research on Asian ethnic medicine. The journal publishes work from scientists in Asian countries, e.g. China, Japan, Korea and India, including contributions from other countries concerning natural products of Asia. The journal is chemistry-orientated. Major fields covered are: isolation and structural elucidation of natural constituents (including those for non-medical uses), synthesis and transformation (including biosynthesis and biotransformation) of natural products, pharmacognosy, and allied topics. Biological evaluation of crude extracts are acceptable only as supporting data for pure isolates with well-characterized structures.
All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymized refereeing by at least two expert referees.
