Abstract

Objectives: In our previous studies we synthesized some potent antiparasitic, anticancer and antimicrobial amidine derivatives. Despite all theirpotent activities, it is well known that due to their cationic charge, amidine derivatives pose a serious problem in terms of bioavailability. The mainpurpose of this study is to prepare amidoxime derivatives of previously synthesized potent amidine derivatives as prodrugs in order to increasetheir bioavailabilities.Materials and Methods: The targeted benzimidazole amidoximes were synthesized from their nitrile derivatives. The nitrile groups of thesebenzimidazole carbonitriles were converted to N-hydroxy benzamidine derivatives (amidoxime derivatives, 20-29) in the presence of NH2OH.HCIand KO-t-Bu in dimethyl sulfoxide. Structures of newly synthesized amidoxime derivatives were elucidated with 1H-NMR, 13C-NMR and some 2DNMR techniques like COSY, NOESY, HSQC and HMBC.Results: A new series of benzimidazole amidoximes were synthesized and their structural elucidations were done in this study.Conclusion: In order to solve the potential bioavailability problem of potent amidine derivatives, we prepared the prodrugs of those potent amidinederivatives as their amidoxime derivatives. In vivo studies of both previous amidine derivatives and amidoxime prodrugs of those amidines whichwere synthesized in this study are planned to perform in our ongoing studies.

Özet

Amaç: Daha önce yaptığımız çalışmalarda, antiparaziter, antikanser ve antimikrobiyal etkili potent aktiviteye sahip bazı amidin türevleri sentezledik. Ancak potent aktivitelerine rağmen, amidin türevlerinin, katyonik yükleri nedeniyle biyoyararlanım açısından ciddi bir sorun oluşturduğu bilinmektedir. Bu çalışmanın temel amacı, daha önce sentezlenen etkili amidin türevlerinin biyoyararlanımlarını artırmak için, ön ilaçları olarak bilinen amidoksim türevlerini hazırlamaktır. Gereç ve Yöntemler: Hedeflenen benzimidazol amidoksimler, nitril türevlerinden hareketle sentezlenmiştir. Bu benzimidazol karbonitrillerin nitril grupları, dimetil sülfoksit içerisinde NH2 0H.HCl ve KO-t-Bu varlığında N-hidroksi benzamidin türevlerine (amidoksim türevleri, 20-29) dönüştürülmüştür. Yeni sentezlenmiş olan amidoksim türevlerinin yapıları ise 1H-NMR, 13C-NMR ve COSY, NOESY, HSQC ve HMBC gibi bazı 2D NMR teknikleri ile açıklanmıştır. Bulgular: Bu çalışmada yeni bir seri benzimidazol amidoxim türevi bileşik sentezlenmiş ve yapıları aydınlatılmıştır. Sonuç: Daha önceki çalışmalarımızda sentezlediğimiz amidin türevleri ile literatürlerde biyolojik açıdan etkili bulduğumuz amidin türevlerinin potansiyel biyoyararlanım problemlerini çözebilmek için, bu çalışmada söz konusu potent amidinlerin ön ilaç formları olan amidoksim türevlerini hazırladık. Etkili amidin türevleri ile bu çalışmada sentezlenen amidoksim türevlerinin in vivo çalışmalarının devam eden araştırmalarımız kapsamında yapılması planlanmaktadır.
