Four noveldendritic molecules bearing a porphyrin core and peripheral cholic acid units (TPPh(Zn) Tetra-CA, TPPh(2H) Tetra-CA, TPPh(Zn) Octa-CA and TPPh(2H) Octa-CA) have been synthesized by the “clickchemistry” approach, using azide-alkyne couplings. These compounds are fully characterized by 1H and 13C NMR spectroscopy and MALDI-TOF. The optical properties of the dendronized porphyrins are studied
四个新的树突状分子带有卟啉核心和外围胆酸单元(TPPh(Zn)Tetra-CA,TPPh(2H)Tetra-CA,TPPh(Zn)Octa-CA和TPPh(2H)Octa-CA)使用叠氮化物-炔烃偶联的“点击化学”方法。这些化合物通过1 H和13 C NMR光谱和MALDI-TOF进行了全面表征。通过吸收和荧光光谱在不同溶剂中研究了树枝状卟啉的光学性质,以便结合卟啉单元的光学响应来研究胆酸单元的两亲性质。与锌络合后,金属化的卟啉(TPPh(Zn)tetra-CA和TPPh(Zn)octa-CA)倾向于在不同极性的溶剂中形成J聚集体,而游离碱卟啉TPPh(2H)tetra-CA和TPPh(2H)octa-CA表现不同。已经通过改变环境的极性,温度和金属化来研究聚集现象。

Novel fluconazole/bileacidconjugates were designed and their regioselective synthesis was achieved in very high yield via Cu(I) catalyzed intermolecular 1,3-dipolar cycloaddition. These new molecules showed good antifungal activity against Candida species.

1,3-Dipolar cycloaddition of propargyl esters of bile acids to azide group attached at different positions of bile acids gave dimers, trimer, and tetramer linked with 1,2,3-triazole. These dimeric and oligomeric structures were able to solubilize hydrophilic dye-cresol red, in nonpolar solvent. (c) 2007 Elsevier Ltd. All rights reserved.
