Abstract

In this work, a single crystal of 5-(2-chloro-6-fluorobenzylthio)-1,3,4-thiadiazol-2-aminecontaining thiadiazole ring was synthesized. The structure of the synthesized crystal was confirmed by 1H-NMR, 13C-NMR and X-ray analysis techniques. Theoretical calculations have been made in order to support experimental results. In this, the geometric parameters of the compound were optimized by the density functional theory(DFT) B3LYP/6-31G(d) method using the gaussian 09 packet program and structural parameters (bond angles, bond lengths and dihedral angles), 1H- and 13C-NMR spectra and frontier molecular orbitals (HOMO-LUMO) of the single crystal have been calculatedtheoretically. Finally, the molecular doking simulation was carried out to inhibit the 2WQY receptor target structure for inhibitor activity study of the synthesized single crystal.

Abstract

Bu çalışmada, tiyadiazol halka içeren5-(2-kloro-6-florobenziltiyo)-1,3,4-tiyadiazol-2-amin tek kristali sentezlenmiştir. Sentezlenen kristalin yapısı, 1H-NMR, 13C-NMR ve X-ışını analiz teknikleri ile aydınlatılmıştır. Deneysel sonuçlara destek olması amacıyla da teorik hesaplamalar yapılmıştır. Bunun içinde bileşiğin geometrik parametreleri gaussian 09paket programı kullanılarak, yoğunluk fonksiyonel teorisi (DFT) B3LYP/6-31G(d) metodu ile optimize edildi ve yapısal parametreleri (bağ açıları, bağ uzunlukları ve dihedral açıları), 1H- ve 13C-NMR spektrumları vesınır moleküler orbitalleri (HOMO-LUMO) teorik olarak hesaplanmıştır. Son olarak, sentezlenen tek kristalin inhibitör aktivite çalışması için, 2WQY reseptör hedef yapısını inhibe etmek amacıyla moleküler doking simülasyonu yapılmıştır.
