Current Medicinal Chemistry - Volume 12, Issue 5, 2005

Analytical chemists have increasingly turned their attention to drug discovery and drug analysis and to solve fundamental questions of biological significance in physiology and genetics. New technologies have been developed, and a variety of instruments have been redesigned for biomedical applications. The development of high-performance liquid chromatography (HPLC) opened a new era in biorelated fields and allowed fas Read More

Oligosaccharides are linked to the protein surface and play roles in a number of biological events. Therefore, much attention is being paid to research to investigate the function of the oligosaccharides. In order to investigate the function of oligosaccharides, many synthetic approaches have been examined by synthesizing O-linked or N-linked glycopeptides. Synthesis of O-linked type oligosaccharides is relatively feasible Read More

Tetrahydropyridine (THP) moiety is a part of many biologically active systems. The discovery of the neurotoxic properties of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) as well as numerous alkaloids, prompted extensive research on the synthesis and pharmacological properties of these compounds. The goal was extending the database for structure-activity relationship (SAR) studies. Consequently, many promising Read More

The article discusses the qualitative and quantitative determination of non-steroidal antiinflammatory drugs like salicin, salicylic acid, tenoxicam, ketorolac, piroxicam, tolmetin, naproxen, flurbiprofen, diclofenac and ibuprofen by reversed phase high performance liquid chromatography (RP-HPLC) and micro-HPLC (μ-HPLC) hyphenated with UV-absorbance and mass spectrometric detection. Both detection methods delivered Read More

Azapeptides, formed by replacing the Cα of amino acid residues by nitrogen, are promising peptidomimetic compounds. Azaamino acids impart a unique conformational property to peptide structures because of the loss of chirality and reduction of flexibility of the parent linear peptide. The peculiar conformational properties make azaamino acids an attractive tool for drug design involving specific secondary structures in pep Read More

Polyhalogenated aromatic arylhydrocarbons (PAHs) such as polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs), the polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) are persistent lipophilic pollutants, which affect female fertility resulting in severe reproductive dysregulation, including anovulation, reduced conception rates, abortion, menstrual abnormalities and d Read More

Analogs of the excitatory neurotransmitter glutamate are potential medicinal agents for a wide variety of neurological disorders. The isoxazole glutamate derivatives represent an important class of compounds because of their receptor specificity and binding affinity. Since the discovery of (S)-2-amino-3-(3- hydroxy-5-methyl-4-isoxazolyl) propionic acid (AMPA) in 1980, numerous analogs built around the isoxazole scaffold ha Read More
