Natural products targeting tumour angiogenesis

open access: yesBritish Journal of Pharmacology, Volume 182, Issue 10, Page 2094-2136, May 2025.
Abstract Tumour angiogenesis is the formation of new blood vessels to support the growth of a tumour. This process is critical for tumour progression and metastasis, making it an attractive approach to cancer therapy. Natural products derived from plants, animals or microorganisms exert anti‐angiogenic properties and can be used to inhibit tumour ...
