The Zika virus (ZIKV) is an arthropod-borne that belongs to the Flaviviridae family. ZIKV infection usually asymptomatic or associated with mild clinical manifestations; however, increased numbers of cases microcephaly and birth defects have been recently reported. To date, neither a vaccine nor antiviral treatment has become available control replication. Among natural compounds recognized for their medical properties, flavonoids, which can be found in fruits vegetables, possess biological...

The protein structure prediction problem continues to elude scientists. Despite the introduction of many methods, only modest gains were made over last decade for certain classes targets. To address this challenge, a social-media based worldwide collaborative effort, named WeFold, was undertaken by 13 labs. During collaboration, laboratories simultaneously competing with each other. Here, we present first attempt at "coopetition" in scientific research applied and refinement problems....

This work describes the synthesis of 1,2,3-triazole amino acid-derived-3-O-galactosides 1-6 and di-lactose-derived glycoconjugate 7 as potential galectin-3 inhibitors. The target compounds were synthesized by Cu(I)-catalyzed azide-alkyne cycloaddition reaction ('click chemistry') between azido-derived acids N3-ThrOBn, N3-PheOBn, N3-N-Boc-TrpOBn, N3-N-Boc-LysOBn, N3-O-tBu-AspOBn N3-l-TyrOH, corresponding alkyne-based sugar 3-O-propynyl-GalOMe, well click chemistry azido-lactose 2-propynyl...

Abstract Every two years groups worldwide participate in the Critical Assessment of Protein Structure Prediction (CASP) experiment to blindly test strengths and weaknesses their computational methods. CASP has significantly advanced field but many hurdles still remain, which may require new ideas collaborations. In 2012 a web-based effort called WeFold, was initiated promote collaboration within community attract researchers from other fields contribute CASP. Members WeFold coopetition...

Biological processes are regulated mainly by the binding of small molecules into cavities distributed throughout biomolecular structure. Computational tools to detect these have an essential role in rational drug design. With exponential availability high-order 3D atomic structures and large sets models, must balance accuracy speed. In this sense, we developed parKVFinder, a parallelized software for geometry-based cavity detection. Here, described its functionalities presented easy-to-use...
