konjugáty

Konjugáty are chemical compounds formed by linking two or more molecules, where at least one of the molecules is a biomolecule such as a protein, peptide, antibody, or nucleic acid. The other molecule, often referred to as the "payload" or "conjugating partner," can be a drug, a toxin, a fluorescent dye, a radiolabel, or another functional group. The process of forming a konjugát is called conjugation.

Conjugation strategies are crucial in various fields of chemistry and biology. For instance, antibody-drug konjugáty (ADCs) are a significant class of targeted cancer therapies. In an ADC, an antibody that specifically recognizes cancer cells is covalently linked to a potent cytotoxic drug. This targeted delivery system aims to deliver the toxic payload directly to tumor cells, minimizing damage to healthy tissues and reducing systemic side effects.

Beyond therapeutics, konjugáty play vital roles in diagnostic imaging and research. Fluorescent konjugáty are widely used in microscopy and flow cytometry to visualize and quantify specific molecules within cells or tissues. Radioconjugates are employed in medical imaging techniques like PET scans to detect and monitor diseases. The precise chemical linkage between the biomolecule and its partner is critical for maintaining the functionality of both components and ensuring the desired outcome of the konjugát.
