Total Synthesis of Distamycin A and 2640 Analogues: A Solution-Phase Combinatorial Approach to the Discovery of New, Bioactive DNA Binding Agents and Development of a Rapid, High-Throughput Screen for Determining Relative DNA Binding Affinity or DNA Binding Sequence Selectivity

Total Synthesis of Distamycin A and 2640 Analogues: A Solution-Phase Combinatorial Approach to the Discovery of New, Bioactive DNA Binding Agents and Development of a Rapid, High-Throughput Screen for Determining Relative DNA Binding Affinity or DNA Binding Sequence Selectivity

The regulation of gene expression is based on the sequence selective recognition of nucleic acids by a host of repressor, activator, and enhancer proteins. Selective external disruption or control of […]

Stereoselective synthesis of nicotinamide β-riboside and nucleoside analogs

Stereoselective synthesis of nicotinamide β-riboside and nucleoside analogs

Nicotinamide riboside (β-NAR) is an intermediate in one biosynthetic pathway by which nicotinamide is converted into NAD. In fact, nicotinamide or nicotinamide riboside derived from degradation of NAD can be […]

Application of a coupled enzyme assay to characterize nicotinamide riboside kinases

Application of a coupled enzyme assay to characterize nicotinamide riboside kinases

Nicotinamide adenine dinucleotide (NAD) has versatile functions in all cells. Besides its involvement in energy metabolism it serves important functions as substrate in a variety of cellular signaling reactions.  Although […]

Electroanalytical  and  isothermal  calorimetric  study  of  As(III) complexation  by the metal  poisoning  remediators,  2,3-dimercapto-1-propanesulfonate  and meso-2,3-dimercaptosuccinic acid

Electroanalytical and isothermal calorimetric study of As(III) complexation by the metal poisoning remediators, 2,3-dimercapto-1-propanesulfonate and meso-2,3-dimercaptosuccinic acid

Arsenic toxicity and its association with human diseases such as blackfoot disease, diabetes, hypertension and some kinds of cancers have been widely considered in the literature.  It  is  well known […]

Design and Synthesisof Gramicidin S Analogs with High Antibiotic Activity

Design and Synthesisof Gramicidin S Analogs with High Antibiotic Activity

N-(2,4-Dinitrophenyl)tetrapeptide p-nitroanilides (Dnp-tetra-peptide-pNA) exhibit characteristic CD spectra when they take on β-turn conformation. Exciton coupling of electric transition dipoles of the two chromophores is thought to be the origin of […]

Chemiluminescent detection systems of horseradish peroxidase employing nucleophilic acylation catalyst

Chemiluminescent detection systems of horseradish peroxidase employing nucleophilic acylation catalyst

The horseradish peroxidase (HRP)-catalyzed chemiluminescent oxidation of luminol is widely used in many molecular biology-based assays, such as Western blots, dot blots, and enzyme-linked immunosorbent assays (ELISAs), as well as […]

Low-dose ribavirin potentiates the antiviral activity of favipiravir against hemorrhagic fever viruses

Low-dose ribavirin potentiates the antiviral activity of favipiravir against hemorrhagic fever viruses

Favipiravir (T-705) is a nucleoside analog that was recently approved as an anti-influenza drug in Japan, and is in Phase 3 clinical trials in the USA for the same indication. […]

Preclinical Studies on the Pharmacokinetics, Safety, and Toxicology of Oxfendazole: Toward First in Human Studies

Preclinical Studies on the Pharmacokinetics, Safety, and Toxicology of Oxfendazole: Toward First in Human Studies

A number of BZ anthelmintics used in veterinary medicine have been considered for transition to human use, including oxibendazole and oxfendazole (OXF). In addition, flubendazole, already approved for use as […]

First report of fluazuron resistance in Rhipicephalus microplus: A field tick population resistant to six classes of acaricides

João Ricardo de Souza Martins and co-workers described the first report of fluazuron resistance in R. microplus, and also report the first tick strain that was multi-resistant to six classes […]

Development of albendazole sulfoxide-loaded Eudragit microparticles: A potential strategy to improve the drug bioavailability

Development of albendazole sulfoxide-loaded Eudragit microparticles: A potential strategy to improve the drug bioavailability

Benzimidazole compounds are especially effective against nematodes found in the gastrointestinal tube in combating adult worms besides their larvae and eggs. They are also highly effective against lung worms. Their […]
