Scalar algorithms for molecular docking in heterogeneous platforms

Posted on 20 November 2011

The high throughput screening of new candidate drugs using computational molecular docking simulations, is one of the most promising techniques of modern biology to design new drugs and evaluate the effectiveness of new pharmaceuticals. The current state-of-the art implementation of molecular docking algorithms for multicore-CPU architectures are able to evaluate the druglikeness of 106 candidate [...] Continue Reading

Computer Aided Fragment-Based Drug-Design

Posted on 19 November 2011

Fragment Based Drug Design Today, the discovery of a new drug is done by experimental and computational small-molecule high throughput screening (HTS) campaigns that select the best hits from libraries up to millions (10^6) drug-like compounds, hoping to find a few high-binding affinity starting hits. However, 10^6 compounds only covers a small fraction of the total chemical [...] Continue Reading

Computer-aided drug design

Posted on 05 November 2011

Today, the use of computational chemistry methods permeates all aspects of the drug discovery process. Some of these computational methodologies (eg: docking) are able to model the physical details of biochemical systems, such as, protein-ligand molecular recognition and binding affinity.

O espaço químico dos fármacos patenteados. Construção e caracterização de uma base de dados pública de moléculas protegidas por patente

Posted on 20 October 2011

O desenvolvimento de um novo fármaco implica um tremendo esforço na optimização de uma série de propriedades, nomeadamente, a: potência, absorção, distribuição, metabolismo, excreção e toxicidade da nova molécula. Adicionalmente, uma outra característica fundamental para viabilizar a futura aplicação do novo fármaco, é a ausência de semelhança com outras entidades químicas já protegidas por patentes [...] Continue Reading
