fe3+

Deferasirox (Fe3+ chelate) is an orally available iron chelator with potential anticancer activity, inhibits the anti-apoptotic activity of MCL-1, and can be used to study iron overload.

Ciclopirox (HOE296b) exerts its action by binding to and chelating trivalent cations, such as Fe3+ and Al3+, thereby inhibiting the availability of essential co-factors for enzymes. Ciclopirox is a synthetic, broad-spectrum antifungal agent with additional antibacterial and anti-inflammatory activities. This may lead to a loss of activity of enzymes that are essential for cellular metabolism, the organization of cell wall structure and other crucial cell functions. In addition, ciclopirox exerts its anti-inflammatory activity by inhibiting 5-lipoxygenase and cyclooxygenase (COX).

Ferric maltol (Iron(III) 2-methyl-4-oxo-4H-pyran-3-olate) is a ferric, non-salt-based oral iron formulation demonstrating improved tolerance in patients with previous intolerance to other iron formulations.

CP 375 is a Fe3+ chelating agent (log K1: 14.50).

AChE-IN-77 (5d) serves as an effective inhibitor of both AChE and BACE1, exhibiting IC50 values of 29.46 µM and 2.85 µM, respectively. It also demonstrates metal chelating ability towards Fe3+ in vitro.

ROS151 is an AChE inhibitor with IC50 values of 14 nM (hAChE), 1.68 μM (eqBChE), and 8.17 μM (hFAAH). Additionally, it acts as a chelating agent for Fe3+ and Cu2+. ROS151 is utilized in research related to Alzheimer's disease.

The compound Sodium Glucoheptonate (H-Quest A300), also known as Sodium Glucoheptonate, is a non-toxic and harmless chelating agent capable of forming stable complexes with divalent and trivalent metal ions such as Ca2+, Fe2+, Fe3+, and Al3+.

Disodium nitrilotriacetate is used as a chelating agent, which forms coordination compounds with metal ions such as Fe3+, Cu2+, and Ca2+.

Difluorinated H2S probe 1 is a fluorescent probe for hydrogen sulfide (H2S).1It selectively fluoresces in the presence of H2S over Zn2+, Fe3+, S2O32-, ClO-, SO32-, H2O2, NO2-, cysteine (Cys), homocysteine (Hcy), and glutathione (GSH) when used at a concentration of 1 μM. Difluorinated H2S probe 1 displays excitation/emission maxima of 365/450 nm, respectively. 1.Zhang, J., Gao, Y., Kang, X., et al.o,o-Difluorination of aromatic azide yields a fast-response fluorescent probe for H2S detection and for improved bioorthogonal reactionsOrg.

pyridoxal isonicotinoyl hydrazone (PIH) is a cell-permeable and relatively non-toxic iron (Fe3+) chelator that shows high iron chelation efficacy both in vitro and in vivo.

Pulcherriminic acid, a cyclic dipeptide antimicrobial compound predominantly found in Bacillus and yeast, exhibits a strong affinity for Fe3+. It chelates iron ions via a non-enzymatic reaction, forming the extracellular red pigment pulcherrimin. This pigment competes for iron nutrition, thereby exerting an antibacterial effect. Pulcherriminic acid holds significant potential for applications in the food, agriculture, and medical industries [1] [2].

Dimerum acid is a dihydroxamate (dihydroxamate) type iron carrier (siderophore) found in Penicillium chrysogenum. It serves as a precursor or degradation product of coprogen and significantly enhances iron uptake in Strategy I plants (such as cucumber) and Strategy II plants (such as maize). At a pH of 6.0, dimerum acid releases bioavailable Fe3+ through ligand exchange with plant-secreted phytosiderophore (phytosiderophore, PS) or EDTA, thereby improving iron supply efficiency in plants. Dimerum acid is applicable in research related to plant iron nutrition and agriculture.

Anguibactin is an antibiotic that functions as an iron carrier, exhibiting strong affinity for Fe³⁺.

Conalbumin (ovotransferrin) is an egg white protein and glycoprotein with antimicrobial, antioxidant, and immunomodulatory properties as a member of the transferrin and metalloprotease families. Conalbumin has a binding logarithm of 15 for Fe3+ at pH 7 or higher.

Apo-Bovine Transferrin is an iron-free transferrin that acts as a ligand for the transferrin receptor, facilitating iron release in endothelial cells. It can bind directly to hephaestin and convert Fe2+ to Fe3+. Apo-Bovine Transferrin likely works alongside ferroportin 1 to mediate iron efflux and is applicable in neuroretina research.

FeTCPP chloride (Iron(III) meso-Tetra(4-carboxyphenyl)porphine chloride) is a metalloporphyrin compound characterized by a central iron ion (Fe3+) coordinated with four 4-carboxyphenylporphine (TCPP) ligands. It serves as a catalyst in catalysis, electrochemical, photochemical, and biomedical research. Under visible light, FeTCPP chloride exhibits high photocatalytic efficiency towards p-nitrophenol. Additionally, it possesses peroxidase-like activity, making it useful in biomimetic catalysis studies.
