This paper reports the preparation and characterization of an Au electrode modified with self-assembled alkane ferrocenes, in the absence and in the presence of beta-cyclodextrins (betaCD). Electrode modification with ferrocene derivatives was achieved through a self-assembled monolayer (SAM)
AM1 calculations on inclusion complexes of cyclomaltoheptaose (beta-cyclodextrin) with 1,7-dioxaspiro[5.5]undecane and nonanal, and comparison with experimental results.

Semiempirical calculations on cyclomaltoheptaose (beta CD), 1,7-dioxaspiro[5.5]undecane (1), nonanal (2), and the inclusion complexes of beta CD with 1 and 2 were carried out using the AM1 method. The structure of beta CD after complete geometry optimization was in very good agreement with

Corporal mechanisms attributed to cancer, such as oxidative stress or the action of cytochrome P450 enzymes, seem to be responsible for the generation of a variety of volatile organic compounds (VOCs) that could be used as non-invasive diagnosis biomarkers. The present work presents an attempt to

The reversible encapsulation of a series of normal alkane guests in a cylindrical host was studied by NMR methods. For small hydrocarbons such as n-pentane or n-hexane, two guests enter the host, and they move freely within. With n-heptane no encapsulation takes place. For longer alkanes such as

Ten children with inflammatory processes in the maxillofacial soft tissues and 10 healthy children were examined using chromato-mass-spectrometry of the chemical composition of oral cavity air. Air samples were collected by an adsorbent sample collector by individual sucking and analyzed on a

The inclusion complexes of cyclomaltoheptaose (beta CD) and heptakis(2,3,6-tri-O-methyl)cyclomaltoheptaose (TM-beta CD) with the four major components of the pheromone of the olive fruit fly (Dacus oleae), namely 1,7-dioxaspiro[5.5]undecane, (-)-alpha-pinene, nonanal, and ethyl dodecanoate, and the

CD4 mimics are small molecules that inhibit the protein-protein interaction between gp120 and CD4, which is a key interaction for the entry of human immunodeficiency virus (HIV) into host immune cells. In the present study, mono-cyclohexyl-type CD4 mimics were designed to form hydrophobic and

Amantadine has been used for decades as an inhibitor of the influenza A virus M2 protein (AM2) in the prophylaxis and treatment of influenza A infections, but its clinical use has been limited by its central nervous system (CNS) side effects as well as emerging drug-resistant strains of the virus.
