“…Reported methods for analysis of many drugs and charge transfer complex studies are studied mostly by direct UV-spectrophotometry [17][18][19][20][21][22][23][24][25] , colourimetry 26 and HPLC 27 . And also, our previous works showed that the EDA complexes have good non-linear optical properties and electrical conductivities [28][29][30] .…”

Carbazole Substituted Pyridopyrimidine (CSPP) was synthesized and Charge transfer complexes with some acceptors such as tetracyanoquinomethane (TCNQ) and 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) have been studied spectrophotometrically in acetonitrile at 21 o C. The stoichiometries of the complexes were found to be 1:1 ratio by the Job method between donor and acceptors with the maximum absorption band at a wavelength of 715 nm for DDQ and 593 nm for TCNQ. The formation constants of the complexes were determined by Benesi-Hildebrand equation. The thermodynamic parameters were calculated by Van't Hoff equations and found spontaneous and exothermic.

“…Çoğu ilaçların bu analizleri, UV spektrofotometre [14][15][16][17][18][19][20][21][22], kalorimetre [23] ve HPLC [24] kullanılarak gerçekleştirilmiştir. Ayrıca, daha önce yapmış olduğumuz çalışmalarımız yük transferi komplekslerinin iyi bir doğrusal olmayan (non-lineer) optik özelliklere ve elektriksel iletkenliklere [25][26][27] …”

ÖZKinesin-5 inhibitörü olarak kullanılan Monastrol, çözücüsüz ortamda alümina sülfonik asit (ASA) katalizörü varlığında 3-hidroksibenzaldehit, tiyoüre ve etilasetoasetat kullanılarak sentezlenmiştir. Elektron verici (Donör, D) olarak monastrol, elektron alıcı (Akseptör, A) olarak tetrasiyanoquinometan (TCNQ) kullanılmış ve 2,3-dikloro-5,6-disiyano-p-benzokinon (DDQ) bileşikleri arasındaki yük transfer kompleksleri asetonitril içinde 21 °C'de spektrofotometrik olarak incelenmiştir. Komplekslerin stokiyometrisi, Job yöntemi kullanılarak incelenmiş, elektron verici ve alıcılar arasında TCNQ ile 742 nm ve DDQ ile 546 nm dalga boyunda maksimum absorbsiyon bandında 1:1 oranında olduğu bulunmuştur. Komplekslerin denge sabiti Benesi-Hildebrand ve termodinamik parametreleri Van't Hoff denklemi ile belirlenmiştir.Anahtar Kelimeler: Spektrofotometre, yük transfer kompleksleri, monastrol, TCNQ, DDQ Synthesis of Monastrol, Kinesin-5 inhibitör and investigation of its charge transfer complexes ABSTRACTMonastrol which is a kinesin-5 inhibitor have been synthesized using 3-hydroxybenzaldehyde, thiourea and ethylasetoasetate in the presence of Alumina Sulphonic Acid (ASA) catalyst in solvent free system. Charge transfer complexes between monastrol as a donor and acceptors such as tetracyanoquinomethane (TCNQ) and 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) have been studied spectrophotometrically in acetonitrile at 21 o C. The stoichiometry of the complexes was found to be 1:1 ratio by the Job method between donor and acceptors with the maximum absorption band at a wavelength of 742nm and 546nm respectively. The equilibrium constants were determined by Benesi-Hildebrand and thermodynamic parameters of the complexes by Van't Hoff equation.
