conjugation of a working substance with a molecular provider of natural or inorganic nature, assisting membrane layer penetration. In this work, the synthetic methods utilized in rational design and preparation of conjugates of bioactive representatives with three types of organic low molecular-weight companies being reviewed. Included in these are iron-chelating agents, siderophores and cell-penetrating peptides. Furthermore, a less known but very promising "molecular umbrella" co
