urpose: The aim of this study was to investigate the cytotoxicity effect, iron chelator and antioxidant activities of iron (III) ions with curcumin ligand that may be used in the treatment of iron overload. 

Materials and Methods: The cytotoxic activities of the ligand and the complex were evaluated by the MTT assay. The SOD activity of the complex of curcumin was determined by using its ability to inhibit the reduction of NBT. The catalytic activity studies of Fe(III) complex in DMSO towards the disproportionation of hydrogen peroxide were also performed.

Results: The IC50 values are found in 6.8 μM catalase activity was measured. Where at a concentration of 2.0 mM, the activity was equivalent to 183.30 U/L. The complex shows a catalase activity. The complex showed minimal toxicity. IC50 values found 5.3 mg/ml. The observed cytotoxicity could be pursued to obtain a potential drug. The iron chelator effects were determined by Ferrozine reagent. Curcumin, the most active extract interfered with the formation of ferrous and ferrozine complex. It demonstrated strong chelating activities. The result showed that the complexes possess considerable SOD activity. This finding indicates that the iron complex is capable of removing free radicals.  

Conclusion:  The study results revealed that the iron(III) complex of curcumin with an appropriate potential drug may act as a protector against oxidative stress. Therefore, all results suggest that curcumin may represent a new approach in the treatment of iron overload.

Kurkumin demir(III) kompleksinin demir şelasyonunun in vitro etkileri

Öz

Amaç: Bu çalışmanın amacı, aşırı demir yüklenmesinin tedavisinde kullanılması muhtemel olan kurkumin ligandı ve demir(III) iyonlarının sitotoksik etkisini, demir şelatörünü ve antioksidan etkinliğini araştırmaktır.

Gereç ve Yöntem: Ligandın ve kompleksin sitotoksik etkileri MTT yöntemi kullanılarak değerlendirildi. Kurkumin kompleksinin SOD etkinliği, kompleksin NBT azaltımını inhibe etme kabiliyetine göre belirlendi. Buna ilaveten, demir(III) kompleksinin DMSO’daki hidrojen peroksitin disproporsiyonu reaksiyonuna yönelik katalitik etkinliği de çalışıldı.

Bulgular: IC50 değerleri, 6.8 μM katalaz etkinliğinde ölçüldü. Konsantrasyonun 2.0 mM, olduğu durumda etkinlik seviyesi 183.30 U/L olarak ölçüldü. Kompleksin katalaz etkinliği gösterdiği ve minimal seviyede toksisiteye sebep olduğu görüldü. IC50 değerlerinin, 5.3 mg/ml’ye denk geldiği görüldü. Gözlenen sitotoksisitenin takip edilmesiyle, potansiyel bir ilacın elde edilmesinin muhtemel olduğu görüldü. Demir şelatörün etkileri Ferrozin reaktif bileşiği ile belirlendi. Demir ve Ferrozine kompleksinin oluşmasına müdahale eden en aktif ekstraktın kurkumin olduğu görüldü. Ayrıca, kurkuminin güçlü şelasyon etkinliğine sahip olduğu görüldü. Elde edilen bulgular bu komplekslerin önemli derecede SOD etkinliğine sahip oldukları görüldü. Dolaysıyla bu bulgular demir kompleksinin serbest radikalleri yok etme gücüne sahip olduğuna işaret etmektedirler.

Sonuç: Bu çalışmada elde edilen bulgular, uygun bir potansiyel ilaç ile beraber kullanıldığında demir(III) kurkumin kompleksinin oksidatif strese karşı bir koruyucu olarak işlev görebileceğini göstermektedir. Dolayısıyla elde edilen bütün bulgular, kurkuminin aşırı demir yüklenmesinin tedavisinde yeni bir yaklaşım olabileceğine işaret etmektedirler.
