 Dendrimerler üç boyutlu, çok dallı,
monodispers, yıldız şeklinde makromoleküllerdir. Dendrimerlerin fiziksel ve
kimyasal özellikleri çekirdek, tekrar eden dallar ve yüzey fonksiyonel grupları
gibi moleküler yapı elemanları tarafından belirlenmektedir. Bu yapı
elemanlarının türü, dendrimerlerin moleküler kapsülleme ve çözünürlük gibi özelliklerinde
belirleyici olmaktadır. Bu çalışmada, yeni nesil Jeffamin^®
D230 (D) ve TREN (T) çekirdekli poli(amido amin) PAMAM
dendrimerlerin, jenerasyon büyüklüğü (D2-D4 ve T2-T4), konsantrasyonu (0-1.0
mM) ve yüzey fonksiyonel gruplarının (NH₂, COOH, TRIS), kandesartan
sileksetil (CC)’in sudaki çözünürlüğüne olan etkisi
araştırıldı. CC’nin (sudaki çözünürlük = 0.0048 mg/mL) gözlemlenen sudaki çözünürlük
artışı, D4.COOH (5.25 mg/mL)> T4.COOH (4.77 mg/mL)> D4.TRIS (0.44
mg/mL)> T4.TRIS (0.32 mg/mL)> D4.NH₂ (0.11 mg/mL)> T4.NH₂
(0.08 mg/mL) sırasındadır.

Evaluation of the effect of surface modified different generation Jeffamine® D230 and TREN-cored PAMAM dendrimers on the aqueous solubility of candesartan cilexetil

Öz

Dendrimers are three-dimensional,
hyperbranched, monodisperse, and starburst macromolecules. The physical and
chemical properties of dendrimers are attributed by their molecular
construction units; namely, core, repetitive branching units, and terminal
functional groups. The type of these units has also a determinant effect on their
molecular encapsulation and solubility properties. In this study, the effect of generation size
(D2-D4 and T2-T4), concentration (0-1.0 mM), and surface functional group (NH₂,
COOH, TRIS) of new-generation jeffamine^® D230 (D) and TREN (T) core PAMAMs
on the aqueous solubility of candesartan cilexetil
(CC) was investigated.

The observed solubility enhancement of CC
(solubility in water = 0.0048 mg/mL) was in the order of D4.COOH (5.25
mg/mL)> T4.COOH (4.77 mg/mL)> D4.TRIS (0.44 mg/mL)> T4.TRIS (0.32
mg/mL)> D4.NH₂ (0.11 mg/mL)> T4.NH₂ (0.08 mg/mL).
