The recognition capabilities of acyclic pyridine-based receptors toward monosaccharides were evaluated. Aminopyridine receptors based on the 2,4,6-trimethyl- or 2,4,6-triethylbenzene frame show high β vs α binding selectivity in the recognition of glucopyranosides. Amidopyridine receptors, which are sterically less hindered at nitrogen, display high efficiency and an inverse selectivity. The 2-aminopyridine group has been established as a highly effective recognition group in the binding of monosaccharides.

The factors influencing the binding properties of receptors 1− 15, which differ in the nature and number of binding and spacer subunits used as the buildings blocks, are discussed.

Abstract Idiosyncratic drug toxicity, defined as toxicity that is dose independent, host dependent, and usually cannot be predicted during preclinical or early phases of clinical trials, is a particularly confounding complication of drug development. An understanding of the mechanisms that lead to idiosyncratic liver toxicity would be extremely beneficial for the development of new compounds. We used microarray analysis on isolated human hepatocytes to understand the mechanisms underlying the idiosyncratic toxicity induced by trovafloxacin. Our results clearly distinguish trovafloxacin from other marketed quinolone agents and identify unique gene changes induced by trovafloxacin that are involved in mitochondrial damage, RNA processing, transcription, and inflammation that may suggest a mechanism for the hepatotoxicity induced by this agent.

In conclusion, this work establishes the basis for future microarray analysis of new compounds to determine the presence of these expression changes and their usefulness in predicting idiosyncratic hepatotoxicity.

In 1994 for instance, in the United States alone, more than 2 million cases of hospitalization and more than 100,000 deaths occurred as a result of adverse drug reactions. In addition, adverse drug reactions may lead to $2 to $4 billion in direct hospital costs per year.

In most cases, the reactions are dose dependent and predictable based on the pharmacology of the agent. Asus Rog Rampage Iv Black Edition Release Date. Aerosoft X Liveries. However in certain cases, unexpected toxicity can occur in a small subset of people receiving the drug. In these cases, the adverse reaction is not related to the pharmacology of the drug and is not dose dependent, because most people tolerate the drug at standard levels. Because the toxicity occurs in low percentages of animals and people, it usually cannot be predicted from preclinical studies; these reactions are referred to as idiosyncratic.

In most of these cases, the liver is the primary target of toxicity. In addition to the potential hazard to patients, these types of reactions are a major obstacle to drug development and can result in the withdrawal from the market of an otherwise efficacious and life-saving drug. A significant number of drugs that showed little to no toxicity in preclinical and clinical trials subsequently were removed from the market because of a small percentage of people who experienced life-threatening or fatal drug reactions; such drugs include troglitazone (withdrawn in May 2000 because of liver toxicity), bromfenac (withdrawn in June 1998 because of liver toxicity), fenfluramine (withdrawn in September 1997 because of heart valve disease), and cerivastatin (withdrawn in August 2001 because of rhabdomyolysis). A number of theories exist regarding the underlying mechanism for idiosyncratic drug toxicity.
