Abstract:The scaled regression coefficients give insight to the complexation mechanisms, which appear to be different for the three types of cyclodextrins.
“…TA is hydrophobic and does not interact with carboxylic acid groups, [112] whereas propranolol is a fairly soluble drug that strongly interacts with acrylic networks. [113,114] Hydrogels with CD moieties present showed extended release of TA when compared with hydrogels with no CD, indicating affinity of TA with the CD cavities control release of the hydrophobic drug.…”
Affinity-based drug delivery systems utilize interactions between the therapeutic drug and the delivery system to manipulate drug loading and to control drug release. In this paper, affinity-based drug delivery system syntheses, types of therapeutic factors delivered, and delivery system loading and release are discussed in detail. The paper is divided into three subsections, based on the type of delivery system: molecular imprinting systems, growth-factor delivery, and cyclodextrin-based delivery. The objective of this paper is to examine the current state of research, highlight the breakthroughs and challenges, point out potential impacts of this relatively new technology, and explore future developmental areas.

“…For example, the small size of the training set of a three term model by Suzuki et al (11) may limit the predictive ability of that model. The narrow range of compounds in the training sets of two models by Klein et al (12,13) also has the same effect. Finally, the fragment based approach utilized by Suzuki et al (14) and Katritzky et al (15) restricts the types of compound that can be analyzed.…”

“…The composition of the training set is also a concern for two models developed by Klein et al (12,13). One is composed of first-order terms while the other contains both linear and non-linear terms.…”

Due to its simplicity, the second model is recommended over the first. The most important descriptor in both models is the calculated log P, indicating that drugs with greater lipophilicity form stronger complexes with beta-cyclodextrin.
“…The selectivity of the interactions with these materials is conditioned by the size of the cavities and the arrangement of their chemical groups. The same ring can guest a bunch of structurally related substances with similar affinity, and in consequence, the specificity of the recognition is quite limited [54]. A more biomimetic and selective approach applies the molecular imprinting technology to reproduce the small, but critical, part of the biomacromolecules responsible for the interaction with the target molecule.…”
