caffeic acid phenethyl ester(cape) suppresses the growth of transformed cells such as human breast cancer cells, hepatocarcinoma , myeloid leukemia, colorectal cancer cells, fibrosarcoma, glioma and melanoma. a group of heterocyclic esters of caffeic acid was synthesized using mitsunobu reaction and the esters were subjected to further structural modification by electrooxidation of the catechol...

abstract among synthetic carriers, dendrimers with the more flexible structure have attracted a great deal of researchers' attention in the field of gene delivery. followed by the promising results upon hydrophobic modification on polymeric structures in our laboratory, alkylcarboxylated poly (propylenimine)-based carriers were synthesized by nucleophilic substitution of amines with alkyl moiet...

The foregone studies have shown that nicotinic acid cannot produce noticeable reductive signal at carbon-based electrodes without appropriate modification of the electrode. This is an obvious reason that mercury is known as the main electrode material for electro-reduction of nicotinic acid. In this study, it has been shown that it is possible to create a remarkable reduction signal for NA at a...

Hydrophobically modified (HM) water-soluble polymers, e.g. cellulose, starch or guar exhibit enhanced solution viscosity and unique rheological behaviour. These properties are explained in terms of intermolecular hydrophobic associations [1]. The general solution viscosity behavior of HM polymers of different hydrophobic chain length (moth frequently in the range of C8 to C24) is characterized ...
