Abstract

In this study, binding activities of the previously synthesized cobalt (II) compound (PcCo) with calf thymus-DNA containing 2, 10, 16, 24-tetrakis 4-(2-phenoxy-1, 3-dioxo-2, 3-dihydro-1H-inden-2-yloxy) phthalonitrile were investigated to determine binding activities by using UV-Vis absorption, fluorescence titration methods. Absorption titration spectra of PcCo in DMF give peaks at about 670 nm for Q-band absorption and about 340 nm for B-band absorption in the absence of calf thymus-DNA. Emission intensities of PcCo in presence of calf thymus-DNA, PcCo gives emission at about 545 nm. Thermal denaturation profile study was systematically studied by UV/Vis spectroscopic technique and melting point temperaturewas found around 7.87 oC for Co (II) phthalocyanine compound. The reduction oxidation behavior of PcCo with calf thymus-DNA was investigated using cyclic voltammetry (CV). Cathodic peak potential and anodic peak potential for PcCo were recorded to be 0.84, -0.36 V for EPc and 0.88 V, 0.15 V, and -0.69 V EPa. The cyclic voltammetric results show one halfreversible reduction oxidation wave. The shift in Epc and Epa potentials indicates that PcCo shows strong interaction with calf thymus-DNA. Further to understand binding activities of PcCo with calf thymus-DNA was studied by using electrophoresis technique. Electrophoresis findings showed that there is decrease in the intensity of CT-DNA bands. All the findings show that PcCo interacts strongly with DNA molecule via an intercaltion binding.

Özet

2,10, 16, 24-tetrakis 4- (2-fenoksi-1,3-diokso-2,3-dihidro-lH-inden-2-iloksi) ftalonitril içeren önceden sentezlenmiş kobalt (II) bileşiğinin (PcCo) CT-DNA ile bağlanma özellikleri UV/Vis absorpsiyon, floresan titrasyonu yöntemleri kullanılarak bağlanma özelliklerini belirlemek için araştırıldı. DMF çözücü ortamında ve DNA'nın yokluğunda, PcCo'nun absorpsiyon titrasyon spektrumu, Q-band için yaklaşık 670 nm'de pik ve B -bandı için 340 nm de pik verir. Calf thymus-DNA, PcCo varlığında PcCo'nun emisyon yoğunluğu yaklaşık 545 nm'de emisyona neden olur. Termal denatürasyon profili çalışması UV-Vis spektroskopik tekniği ile sistematik olarak incelenmiş ve Co (II) ftalosiyanin bileşiği için erime noktası sıcaklık değeri 7.87 oC civarında bulunmuştur. CTDNA yokluğunda ve varlığında PcCo'in redüksiyon oksidasyon davranışı, dönüşümlü voltametri (CV) ile incelendi. PcCo için katodik pik ve anodik pik potansiyelleri, EPc için 0.84, -0.36 V ve 0.88 V, 0.15 V ve EPa için -0.69 V olarak kaydedildi. Dönüşümlü (cyclic) voltametri sonuçlar, bir yarı-tersinir redaksiyon oksidasyon dalgasını göstermektedir. Epc ve Epa potansiyelindeki değişim, PcCo'in CT-DNA'yla güçlü etkileşim gösterdiğini önermektedir. PcCo'in CT-DNA ile olan etkileşimi ayrıca jel elektroforez yöntemi kullanılarak araştırılmıştır. Jel elektroforezi sonuçları, CT-DNA bantlarının yoğunluğunda azalma olduğunu gösterdi. Tüm bulgular, PcCo ile CT-DNA molekülü arasındaki etkileşimin interkalatif bağlanma türü olduğunu göstermektedir.
