CYP3A4
CYP3A4 is a low specificity isoenzyme of the CYPs family, which contributes to the metabolism of approximately 50% of all marketed drugs. Induction or inhibition of CYP3A4 activity results in the varied oral bioavailability and unwanted drug-drug, drug-food, and drug-herb interactions.

CYP2D6 and Tamoxifen Metabolism
Tamoxifen is an important adjuvant endocrine therapy in estrogen receptor (ER)-positive breast cancer patients. It is metabolized into its most active antiestrogenic metabolite endoxifen, predominantly by cytochrome P450 2D6 (CYP2D6). Many factors, including genetic variation in CYP2D6, influence tamoxifen metabolism and pharmacokinetics.

Cyclodextrins/Estrogens Inclusion Complexes
In the pharmaceutical industry, cyclodextrins (CDs) are frequently used to improve the aqueous solubility, stability, and bioavailability of medications. Because estrogens have a low polarity, they can interact with some cyclodextrins’ hydrophobic cavities to create inclusion complexes, if their geometric properties are compatible. Estrogen-CD complexes have been widely applied in several fields for various objectives.

Cyclodextrins as Anti-inflammatory Agents
Cyclodextrins (CDs) are a well-known excipient for complexing and drug delivery. Anti-inflammatory drugs and bioactive compounds with similar activities have been favored from these CD processes. CDs also illustrate anti-inflammatory activity per se.

Cyclodextrins and Their Derivatives as Drug Stability Modifiers
Cyclodextrins (CDs) are versatile excipients that are widely used in the pharmaceutical industry as receptor molecules to form complexes with drugs. CDs are cyclic oligosaccharides composed of α-1,4-linked D-glucopyranoside subunits obtained through enzymatic starch degradation.

Cyclodextrin-Based Nanosponges and Proteins
Cyclodextrin-based nanosponges (CD-NSs) have gained importance in drug delivery in the last years due to their easy synthesis and versatility. However, their use as carriers for the delivery of macromolecules such as proteins is less known and sometimes difficult to consider. In this entry, the authors summarize and highlight the multiple possibilities of CD-NSs to deliver active proteins, improving their activity or stability. Starting with a brief description of CD-NSs and their characteristics, the entry will be focused on several proteins, such as (1) Lipase, (2) Insulin and (3) Nisin, for chemical or pharmaceutical applications. The revised results demonstrated that CD-NSs can generate different and interesting applications with proteins. These results could be added to their uses with small drugs, being an interesting alternative for protein delivery and applicability.

Cyclodextrin-Based Drug Delivery Systems
Cyclodextrin-based nanosponges (CDNSs) are complex macromolecular structures composed of individual cyclodextrins (CDs) and nanochannels created between cross-linked CD units and cross-linkers.

Cyclodextrin Multicomponent Complexes: Pharmaceutical Applications
Cyclodextrins (CD) are a family of macromolecules obtained by enzymatic degradation of starch. Their structure resembles a truncated cone, with a somewhat lipophilic central cavity and an external hydrophilic surface.  Due to these characteristics the pharmaceutical applications are mostly related to the ability of CDs to form inclusion complexes, formed by interactions between guest (drug) and host (CD) molecules, and they have the ability to modulate several properties positively affecting the performances and therapeutic profiles of drugs. Besides, a drug–CD complex with the addition of an auxiliary substance, that are called multicomponent or ternary complex, can have a synergic effect, allowing the use of low concentrations of the host compounds, thereby optimizing the cost, toxicity and formulation volume in the final product. Also, these additives such as amino acids, organic acids and bases, and water-soluble polymers interacting with CDs can modulate in vitro and in vivo drug dissolution, thereby modifying the drug’s pharmacokinetic profile.

Cyclo- and Polyphosphazenes for Biomedical Applications
Cyclic and polyphosphazenes are extremely interesting and versatile substrates characterized by the presence of -P=N- repeating units. The chlorine atoms on the P atoms in the starting materials can be easily substituted with a variety of organic substituents, thus giving rise to a huge number of new materials for industrial applications. A wide variety of new phosphazene systems, either trimeric or polymeric, have been developed as biomaterials in view of different applications. The materials to apply in biomedical applications should be biocompatible.
