Since iron is essential for the vital activity of almost all organisms, including mammals and bacteria, the proteins involved in its metabolism can serve as potential targets in the development of new promising antimicrobial agents. Such targets include endogenous mammalian biomolecules, heme oxygenases, siderophores, protein 24p3, as well as bacterial heme oxygenases and siderophores. Other proteins that are responsible for the delivery of iron to cells and its balance between bacteria and the host organism also attract certain particular interest. The review summarizes data on the development of inhibitors and inducers (activators) of heme oxygenases, selective for mammals and bacteria, and considers the characteristic features of their mechanisms of action and structure. Based on the reviewed literature data, it was concluded that the use of hemin, the most powerful hemooxygenase inducer, and its derivatives as potential antimicrobial and antiviral agents, in particular against COVID-19 and other dangerous infections, would be a promising approach. In this case, an important role is attributed to the products of hemin degradation formed by heme oxygenases in vitro and in vivo. Certain attention has been paid to the data on the antimicrobial action of iron-free protoporphyrinates, namely complexes with Co, Ga, Zn, Mn, their advantages and disadvantages compared to hemin.

Intracellular RNLS is a FAD-dependent oxidoreductase (EC 1.6.3.5), while extracellular RNLS lacks its N-terminal peptide, FAD cofactor, and exhibits various protective effects in a non-catalytic manner. Certain evidence exists, that plasma/serum RNLS is not an intact protein secreted into the extracellular space, and exogenous recombinant RNLS is effectively degraded during short-term incubation with human plasma samples. Some synthetic analogues of the RNLS sequence (e.g. the Desir's peptide RP-220, a 20-mer peptide corresponding to the RNLS sequence 220-239) have effects on cell survival. This suggests that RNLS-derived peptides, formed during proteolytic processing, may have own biological activity. Based on results of a recent bioinformatics analysis of potential cleavage sites of RNLS (Fedchenko et al., Medical Hypotheses, 2022) we have investigated the effect of four RNLS-derived peptides as well as RP-220 and its fragment (RP-224) on the viability of two cancer cell lines: HepG₂ (human hepatoma) and PC3 (prostate cancer). Two RNLS-derived peptides (RP-207 and RP-220) decreased the viability of HepG₂ cells in a concentration dependent manner.
