SDHAF2 Inhibitors
Chemical inhibitors of SDHAF2 function in various ways to impede its role in the maturation of Fe-S proteins involved in electron transfer. Thenoyltrifluoroacetone, as a chelating agent, can bind to iron-sulfur clusters that are essential for the activity of SDHAF2. This binding action effectively prevents the proper assembly of these crucial clusters, thus directly inhibiting the function of SDHAF2. Similarly, Dimercaprol, another chelating agent, can bind heavy metals that might be required as cofactors by SDHAF2, which would interfere with the maturation process of Fe-S proteins that SDHAF2 facilitates. Phenylarsine oxide, which interacts with vicinal dithiols, could modify critical cysteine residues if present in SDHAF2, thereby inhibiting its activity. Moreover, Carboxin and TTFA (thenoyltrifluoroacetone) target SDH by binding to its quinone binding site, which disrupts the electron transfer chain and compromises the maturation of Fe-S clusters by SDHAF2.
Malonate, a competitive inhibitor of succinate dehydrogenase (SDH), indirectly inhibits SDHAF2 by disrupting the SDH enzyme complex, which relies on Fe-S clusters assembled and stabilized by SDHAF2. Atpenin A5 and 3-Nitropropionic acid also inhibit SDH, with the former specifically targeting mitochondrial complex II, where SDHAF2 is essential for the insertion of Fe-S clusters, and the latter irreversibly binding to SDH. Aurachin C impedes the menaquinone-binding site in SDH, leading to a disruption in the electron transfer chain that necessitates the Fe-S cluster assembly function of SDHAF2. Lastly, Quinolinic acid's inhibition of enzymes requiring NAD+ indirectly affects the SDH complex by impacting the NAD+ dependent reactions, which could reduce the functional efficacy of the SDH complex and, as a result, the role of SDHAF2.

2-Thenoyltrifluoroacetone | 326-91-0 | sc-251801 | 5 g | $37.00 | 1 | |
Thenoyltrifluoroacetone is a chelating agent that can bind iron-sulfur (Fe-S) clusters, which are crucial for the function of SDHAF2. By sequestering the iron, it prevents the proper assembly of Fe-S clusters, thereby inhibiting the function of SDHAF2, which is responsible for the maturation of certain Fe-S proteins involved in electron transfer. | ||||||
Atpenin A5 | 119509-24-9 | sc-202475 sc-202475A sc-202475B sc-202475C | 250 µg 1 mg 10 mg 50 mg | $195.00 $540.00 $2905.00 $12885.00 | 17 | |
Atpenin A5 specifically inhibits mitochondrial complex II, which consists of four subunits, one of which requires SDHAF2 for the insertion of Fe-S clusters. Inhibition of complex II by Atpenin A5 therefore disrupts the functional pathway of SDHAF2 by impeding the operation of the complex that relies on the proper assembly and stabilization of Fe-S proteins, a process involving SDHAF2. | ||||||
Carboxine | 5234-68-4 | sc-234286 | 250 mg | $21.00 | 1 | |
Carboxin is an inhibitor of SDH, and by extension, it can inhibit SDHAF2 functionally. It binds to the quinone binding site of SDH, interrupting the electron transfer chain in which SDHAF2 is involved by assisting the incorporation of Fe-S clusters to SDH subunits. This inhibition compromises the SDHAF2-dependent maturation of Fe-S proteins, crucial for SDH function. | ||||||
3-Nitropropionic acid | 504-88-1 | sc-214148 sc-214148A | 1 g 10 g | $82.00 $459.00 | ||
3-Nitropropionic acid is an irreversible inhibitor of SDH. By inhibiting SDH, it disrupts the functional complex where SDHAF2 operates. Since SDHAF2 is essential for the proper assembly of Fe-S clusters in SDH, inhibition of SDH functionally inhibits SDHAF2 by collapsing the electron transfer chain activity that SDHAF2 supports. | ||||||
Phenylarsine oxide | 637-03-6 | sc-3521 | 250 mg | $41.00 | 4 | |
Phenylarsine oxide is a compound known to interact with vicinal dithiols and can inhibit enzymes that have critical cysteine residues in their active sites. If SDHAF2 has such residues that are critical for its maturation role of Fe-S clusters, phenylarsine oxide binding would inhibit SDHAF2's functional activity by modifying those cysteine residues. | ||||||
Quinolinic acid | 89-00-9 | sc-203226 | 1 g | $32.00 | 7 | |
Quinolinic acid can inhibit various enzymes involved in the metabolism of amino acids and other pathways that require NAD+ as a coenzyme. Considering that SDH is part of the Krebs cycle and relies on NAD+, an inhibition of NAD+ synthesis or regeneration could indirectly affect SDH function, and consequently inhibit SDHAF2 by reducing the functional efficacy of the SDH complex. | ||||||
