    New voltammetric method for determination and electrochemical behaviors of oxaliplatin by CPT-BDD electrode
    (ICNTC, 2020) Aslan, Mehmet; Levent, Abdulkadir
    Various drugs made of metal compounds have been used in many diseases including cancer[1]. Studies on Oxaliplatin in the literature are these [2-6]. Oxaliplatin (OxPt), which is a platinum analogue with anti-cancer effect, was accentuated. OxPt is separated from cisplatin, one of analogues of platinum, by replacing 1,2-diaminocyclohexane with amine groups. In this study, a simple, fast and sensitive voltammetric method was developed for OxPt which shows anticancer effects with cytotoxic properties. The boron-doped diamond (BDD) electrode was activated electrochemically in cathodic direction in 0.5 M H2SO4 medium. Electrochemical properties of OxPt were investigated on BDD electrode surface using square-wave and cyclic voltammetry techniques. OxPt in Britton-Robinson(BR) buffer (pH 5.0) gave a well-determined voltammetric response at +1.01 V (vs. Ag/AgCl) using the square-wave voltammetry technique. The developed voltammetric technique was found to be linear with the concentration range of 1.0-3.5 μM in the BR (pH 5.0) medium and the limit of detection was 0.276 μM (0.109 μg mL-1 ). Recommended method was successfully applied to drug forms of OxPt.

    Okzaliplatinin elektrokimyasal özellikleri ve miktar tayini
    (Batman Üniversitesi Fen Bilimleri Enstitüsü, 2019-04-29) Aslan, Mehmet; Levent, Abdulkadir
    Bu tez çalışmasında, sitotoksik özelliğe sahip anti kanser etki gösteren Okzaliplatin için basit, hızlı ve duyarlı bir voltametrik yöntem geliştirilmiştir. Bor katkılı elmas (BDD) elektrotu katodik yönde 0.5 M H2SO4 ortamında elektrokimyasal olarak aktive edilmiştir. Okzaliplatinin elektrokimyasal özellikleri BDD elektrot yüzeyinde kare-dalga ve dönüşümlü voltametri teknikleri kullanılarak incelenmiştir. Kare-dalga voltametri tekniği kullanılarak Britton Robinson (BR) tamponu (pH 5.0) içerisinde Okzaliplatin, +1.01 V (vs. Ag/AgCl) gerilim değerinde iyi belirlenmiş voltametrik bir yanıt vermiştir. Geliştirilen voltametrik teknik BR (pH 5.0) ortamında 1.0-4.5 μM derişim aralığında doğrusal olduğu ve gözlenebilirlik sınırı 0.276 μM (0.109 μg mL-1) olarak saptanmıştır. Önerilen yöntem Okzaliplatin ilaç şekillerine başarılı bir şekilde uygulanmıştır.
