Among the physicochemical properties for compounds with pharmaceutical<br />

potential, the solubility and the permeability are the most important ones and<br />

should have a desirable status. An acceptable condition of these properties is<br />

associated with adequate absorption, distribution, metabolism and excretion,<br />

as long as the compound does not exceed the toxicity allowed to reach the<br />

phase I of clinical trials in humans. In the search for drugs with real<br />

pharmaceutical potential, it is considered that the aforementioned properties<br />

are equal, or even more important than the optimization of interactions with<br />

biological receptors.<br />

Various physicochemical descriptors, like logP (logarithm of the partition<br />

coefficient between water and 1-octanol, related to the permeability), have been<br />

proposed to discriminate and molecules with potential application in the<br />

pharmaceutical industry, however, all of them apply to molecules of low<br />

molecular weight, and limited analysis have done about macromolecular<br />

systems.<br />

Taking as starting point the progress in the cyclodextrins chemistry, in this work<br />

was carried out the synthesis of monodisperse dendritic derivatives of βCD,<br />

where systematic structural modifications were made and their effect on<br />

properties like solubility and permeability was analyzed. The results allow<br />

establishing some preliminary rules of discrimination for macromolecular<br />

systems, and place these materials as very attractive ones for further<br />

applications in the formulation and drug delivery fields.<br />
