Abstract
Eight novel clerodane diterpenoids (1-8) were isolated from the twigs of Casearia graveolens. Their structures were elucidated through comprehensive nuclear magnetic resonance (NMR), high-resolution electrospray ionization mass spectrometry (HR-ESI-MS), and electronic circular dichroism (ECD) analyses. In addition to structural determination, surface plasmon resonance (SPR) assays were conducted to investigate molecular interactions, revealing that compound 8 exhibited high affinity for vascular endothelial growth factor receptor 2 (VEGFR2), a key regulator of tumor angiogenesis. Subsequent in vivo experiments demonstrated that compound 8 effectively inhibited angiogenesis and displayed significant antitumor activity by suppressing tumor proliferation and metastasis in zebrafish xenograft models. These findings suggest that compound 8 holds promise as an anticancer lead compound targeting VEGFR-2 to obstruct tumor angiogenesis.
