Abstract

B12
vitamini yapısında bulunan benzimidazol halkası ve histidinin yapısında bulunan
imidazol halkası; tıpta, eczacılıkta, ilaç kimyasında önemli biyolojik ve
klinik uygulamalara sahip heterosiklik yapılardır. Bu yapıların anthelmintik,
antifungal, antiviral ve anti-HIV gibi birçok farklı biyolojik aktiviteye sahip
olması ve son zamanlarda antikanser ajan olarak kullanılması dikkatleri bu
yapılar üzerine çekmektedir. Bu çalışmada benzimidazol/imidazol halkası içeren
altı ilaç molekülünün ters faz sıvı kromatografik yöntemle %40 (v/v) ACN:H2O
içeren mobil faz ortamında
iyonlaşma/protonasyon sabitleri
belirlenmiştir. Deneysel çalışmalarda Gemini NX
C18 (250 x 3.0 mm I.D., 5 µm) kolon kullanılmıştır ve kromatografik analizler 1 mL/dakika
akış hızında, 30
°C’de gerçekleştirilmiştir. Abraham çözünen
tanımlayıcıları ve ters faz sıvı kromatografik yöntemle elde edilen bu alıkonma
verileri kullanılarak bu altı ilaç molekülünün lipofilisite ve çözünürlük
değerleri hesaplanmıştır.

Abstract

The
benzimidazole ring in the structure of B12 vitamin and the imidazole ring in
the structure of histidine are heterocyclic structures with important
biological and clinical applications in medicine, pharmacy and pharmaceutical
chemistry.
These structures have
many different biological activities such as anthelmintic, antifungal,
antiviral and anti-HIV and have recently been used as an anticancer agent,
draws attention to these structures.
In this study, the ionization/protonation constants of six drug
molecules which have containing benzimidazole/imidazole moiety were determined
in mobile phase media containing 40% (v/v) ACN:H2O by reversed phase
liquid chromatographic method.
Gemini NX C18 (250 mm
× 3.0 mm I.D., 5
µm) column was used in
experimental studies and chromatographic analyzes were performed at a flow rate
of 1 mL/min and at 30°C. The lipophilicity and solubility values of these six
drug molecules were calculated using the Abraham solute descriptor values and the
retention data obtained by the reversed phase liquid chromatographic method
