    Cyclic peptides naturally occur in plants, fungi, and animals and have the potential to treat diseases. The purpose of this project is to optimize the bioactivity of a cyclic hexa-peptide that is known to disrupt cell division in certain cells. A set of side chain analogues will be synthesized using solid-phase peptide synthesis. The synthetic products will be analyzed by mass spectrometry, and their biological activity will be assessed in HeLa cells. Based on these results, a strategy will be developed to improve cyclic peptides as drug candidates by changing non-essential side chain amino acids and observing the effects on the disruption of the cell cycle. The outcomes will help future efforts toward improving this drug scaffold.
