“…Integrin antagonists comprise molecules that can bind and interfere with the activity of the cellular receptors integrins. Some proteins or peptides are found in snake venoms such as the C-type lectins EMS6 ( Marcinkiewicz et al, 2000 ) and Vixapatin ( Momic et al, 2012 ) or disintegrins ( Calvete, 2005a ), or found in other animals venoms such as arthropods ( Khamessi et al, 2018 ). The snake venom disintegrin family comprises a group of cysteine-rich proteins (40–100 amino acids) found in the venom from snakes from Elapidae, Viperidae, Atractaspididae, and Colubridae families ( Kini and Evans, 1992 ; Calvete et al, 2005b ; Arruda Macedo et al, 2015 ).…”
