Title: Innovations of Krzysztof Darlak

Introduction

Krzysztof Darlak is a notable inventor based in Louisville, KY (US). He has made significant contributions to the field of peptide synthesis, holding three patents that showcase his innovative approaches. His work primarily focuses on cyclic peptide mixtures and their applications in various scientific domains.

Latest Patents

Darlak's latest patents include "Cyclic peptide mixtures via side chain or backbone attachment" and "A method of preparing cyclic peptide mixtures via side chain or backbone and solid phase synthesis." These patents describe a method for creating libraries of cyclic peptide mixtures that are useful for screening purposes. The process involves attaching an amino acid to a solid support through its side chain or backbone, mimicking solution cyclization procedures with linear peptides. The preferred embodiment utilizes Boc chemistry for peptide synthesis, where a trifunctional amino acid is initially attached by the aspartyl side chain. Cyclization is achieved using uronium reagents with racemization suppressants, and a strong acid (HF) is employed for deprotection and cleavage. This strategy allows for the preparation of a series of cyclic peptide mixtures, expandable to include at least twenty different amino acids at each position, except for the resin-linked position where most attachments are by Asp, Lys, Glu, or Orn. The cyclic peptide mixtures can vary in ring size from about four to twelve residues.
