Bazı Benzotiyazol Türevlerinin Antifungal Aktivitesinin Değerlendirilmesi

Hayvanlarda oluşan candida kaynaklı hastalıklara çözüm üretmek amacıyla daha önceden sentezi yapılmış bileşikler benzer metot kullanarak tekrar sentezlenmiş ve antifungal etkinlikleri değerlendirilmiştir. Mevcut çalışmada, 10 tane benzotiyazol türevi bileşik (4a-4j), antifungal aktivitelerini değerlendirmek üzere yeniden sentezlenmiştir. Sentezlenen bileşiklerin yapı tanımlamaları IR, 1HNMR, 13C-NMR ve HRMS (Kızılötesi Spektroskopi, 1H Nükleer Manyetik Rezonans Spektroskopisi, 13C Nükleer Manyetik Rezonans Spektroskopisi, Yüksek Çözünürlüklü Kütle Spektrometresi) spektroskopik yöntemleri kullanılarak gerçekleştirilmiştir. Yeniden sentezlenmiş bileşiklerin Candida türlerine karşı MIC50 (Minimum İnhibitör Konsantrasyon) değerleri in vitro deneyler yapılarak değerlendirilmiştir. Yapılan aktivite çalışmaları sonucunda 4c ve 4d bileşikleri önemli aktivite göstermiştir. 4d bileşiğinin Candida krusei’ye karşı 1.95 µg / mL MIC50 değeri ile güçlü bir türev olduğu bulunmuştur.

Evaluation of Antifungal Activity of Some Benzothiazole Derivatives

The antifungal activity of the previously synthesized compounds was evaluated in order to provide solutions to the candida-induced diseases in animals. In the present study, 10 benzothiazole derivatives (4a-4j) were re-synthesized to evaluate their antifungal activity. IR, 1HNMR, 13C-NMR and HRMS (Infrared Spectroscopy, 1H Nuclear Magnetic Resonance Spectroscopy, 13C Nuclear Magnetic Resonance Spectroscopy, High Resolution Mass Spectrometry) spectroscopic methods, determined the structure of the synthesized compounds. MIC50(Minimum Inhibitory Concentration) values of the re-synthesized compounds against Candida species were evaluated by in vitro experiments. As a result of activity studies, it was found that compounds 4c and 4d showed significant activity. Compound 4d was found to be the most potent derivative against Candida krusei with a MIC50 value of 1.95 µg / mL.
