“…One of the promising candidate is Sanguinarine Chloride (SC) (Mackraj et al, 2008;Basu and Kumar, 2016), a benzo phenanthridine alkaloid derived from the root of Sanguinaria Canadensis and other poppy-fumaria species, which has been proved to exert anti-tumor properties due to its anti-proliferation, antiangiogenic and anti-invasive properties in various preclinical studies (Gaziano et al, 2016;Achkar et al, 2017). Specifically, SC could inhibit angiogenesis of cancer cells via blocking VEGF-induced vessel growth, cell migration, sprouting, and survival (Galadari et al, 2017;Xu et al, 2012;Eun and Koh, 2004;Basini et al, 2007a;Basini et al, 2007c). As the fact that neovascular vessels built in ocular diseases has the similar pathology features with tumor, which are all built to compensate for the lack of oxygen (Hennig and Goepferich, 2015), we hypothesed that SC might also be a suitable antiangiogenic treatment for ocular neovascular diseases.…”
