Design of Antibacterial Peptides with Reduced Hemolytic Activity on the Basis of Linear Cytolytic Peptides from Spider Venom

Antimicrobial peptides are alternative to classical antibiotics. However, their use is hindered by their undesirable activity against erythrocytes, hemolytic activity. At the moment there are no programs for calculating the hemolytic activity of peptides in which only the amino acid sequence of the peptide is used. The task of this work is to develop an algorithm for predicting the hemolytic activity of peptides with a length of 20-40 amino acid residues based on their free energy of incorporation into the zwitterionic lipid bilayer. As a result, 2 equations based on the multiple regression model were obtained. The obtained equations can in most cases, in good agreement with the experimental data, predict the hemolytic activity of linear peptides. In addition, there is a literature review, which presents the current state of the problem of the relationship between the hemolytic activity of peptides and their biophysical properties.

Student Theses at HSE must be completed in accordance with the University Rules and regulations specified by each educational programme.

Summaries of all theses must be published and made freely available on the HSE website.

The full text of a thesis can be published in open access on the HSE website only if the authoring student (copyright holder) agrees, or, if the thesis was written by a team of students, if all the co-authors (copyright holders) agree. After a thesis is published on the HSE website, it obtains the status of an online publication.

Student theses are objects of copyright and their use is subject to limitations in accordance with the Russian Federation’s law on intellectual property.

In the event that a thesis is quoted or otherwise used, reference to the author’s name and the source of quotation is required.
