Obtaining structural information on fragment-protein target is a key factor and also a major limitation. We’ve used MED-SuMo and MED-Hybridise to query and mine the PDB seeking for similar interaction surfaces. MED-portions were used to design novel scaffolds (GPCR) and decorate a given scaffold (kinase). We have analysed the scaffolds in regard to their diversity, their presence in PubChem, PDB and other libraries.

Prostanoids originate from PGHS action on the 20-carbon polyunsaturated fatty acid: DGLA, AA and EPA. We used cDNA expression in Saccharomyces cerevisiae and enzyme immunoassays to compare the activities of two mouse PGHS isoforms and cDNAs encoding mouse prostaglandin I synthase and thromboxane A synthase and genomic DNA encoding Trypanosoma brucei prostaglandin F synthase. All genes were active and were put in Transgenic Arabidopsis thaliana plants producing DGLA.

Very long chain polyunsaturated fatty acids (VLCPUFAs) are declining in reserves, since they are produced by oily fish. VLCPUFAs are important in human nutrition because they are responsible for the production of inflammatory mediators such as prostaglandins, the regulation of cholesterol synthesis and its transport, and the maintenance of cellular membranes. This research aims to produce VLCPUFAs in edible plants.

We report the use of qPCR technique to follow the thermal unfolding of proteins by the binding of the dye SYPRO Orange, and exploit its potential as a robust and high-throughput primary screen for small molecule drug discovery.

We transfected siRNA targeting HIV-1 promoter region into a cell line productively infected with HIV-1. ChIP analysis revealed that the RNA duplex induced transcriptional gene silencing and enrichment of Ago1, H3K9me2, and HDAC1 in HIV promoter region to form heterochromatin structure. The data indicates RNA duplex induces the latent phase of HIV infection, since the chromosome formation is very similar to the state of HIV latently infected cell lines

Three proteases involved in the contact phase of vertebrate blood coagulation were searched in genomes of amphibians, birds and mammals. Several data sources were used during this bioinformatics analysis. Our survey confirmed that the vertebrate contact phase has occurred by way of a series of gene duplications during the course of several hundred million years of evolution, beginning with the appearance of fXII and a PK-fXI predecessor in amphibians.

Image processing is a very relevant area of computer science with applications in many domains. Quantitative analysis and interpretation of digitized images is currently an important tool in several scientific domains. The aim of the present work is the development of shape discrimination and size classification algorithms for liquid drops in monochromatic digitized frames.

PMD, an insect repellent that can be derived from steam distillate residue of leaves of lemon eucalyptus. No QSAR studies are known in literature. We performed ab initio (RHF/6-31G**) study of PMD derivatives. A 3D pharmacophore for repellent activity was also developed. Results indicate lipophilicity, MEP separation and localized negative MEP by oxygen atom have roles for repellency. The pharmacophore is consistent and allowed design of more effective insect repellents.

As part of the Drug Design in Medicinal Chemistry Program of the UNAM, new methylthiomorpholinphenol compounds with cardiovascular effect, were studied. One of them, FESCDIPINE II, was an excellent antihypertensive drug, that has low toxicity and preliminary studies indicate that the Angiotensin-converting enzyme (ACE) system is the biological target of this compound.
