Assay
Hemolytic
Cycloviolacins Y4 and Y5 are the most hemolytic of the new cyclotides, both being more potent than the prototypic cyclotide kalata B1. By contrast, cycloviolacin Y1 is substantially less active than all of the other cyclotides tested. [...]Wang CK et al. (2007) J Nat Prod 71:47-52
Anti-HIV
All cyclotides tested from V. yedoensis demonstrated anti-HIV activity, with cycloviolacin Y5 being the most potent. [...]Wang CK et al. (2007) J Nat Prod 71:47-52
Nematocidal
A range of natural variants were selected based on net charge and/or hydrophobicity and were tested alongside the prototypic cyclotide kB1 in larval development assays with H. contortus and T. colubriformis. [...]Colgrave ML et al. (2008) Chembiochem 9:1939-1945
