Natural Inhibitors of the Aromatase Enzyme

Roberto Gil
2000 Molecules  
The results of three years of search for natural aromatase inhibitors will be presented. Estrogen biosynthesis is catalyzed by the aromatase enzyme complex. This complex if made up of a member of the cytochrome P450 superfamily of enzymes known as cytochrome P450 aromatase (P450arom, produced by the CYP19 gene). Associated with this enzyme one finds the flavoprotein NADPH cytochrome P450 reductase. These two enzymes catalyze the aromatization of the A ring of androgens to form the
more » ... phenolic ring of the estrogens. This reaction involves three sequential oxidations of the C-19 methyl group of the substrate (testosterone and androstenedione), its elimination as formic acid and the aromatization of the A ring to afford 17β-estradiol y estrone, respectively. This is the only reaction found in vertebrates in which an aromatic ring is introduced in a molecule. The regulation of this enzyme plays an important role in several physiological processes and in certain diseases, the most important of which is hormone dependent breast cancer. The use of aromatase inhibitors to treat this disease is now very commonplace. There are two kinds of inhibitors, competitive ones and suicide inhibitors; both types include both steroidal and non-steroidal compounds. Due to their great therapeutic importance, presently the list of inhibitors is quite long, but only five have been shown to be relatively safe and to possess reasonable clinical efficacy. These are: aminoglutetimide, 4-hydroxyandrostenedione, anastrozol, letrozol y vorozol; the last three being third generation non-steroidal inhibitors. On the other hand, a few plant secondary metabolites have shown significant inhibitory activity towards the aromatase enzyme. For this reason we consider the search for and characterization of novel natural products with this type of activity to be interesting. At this conference we will present the results of three years of joint research with colleagues from the Department of Clinical Biochemistry of our faculty, which may be summarized as follows: a) A group of sesquiterpene lactones isolated from different species of Asteraceae inhibited the activity of the aromatase enzyme in human placenta microsomes. The three most active compounds were the guaianolides 10-epi-8-desoxycumambrine B, dehydroleucodine and ludartine. b) Complete kinetic studies of these compounds as well as differential UV-Vis studies, were done to measure their binding affinity towards the iron of the heme group found in the active site of the enzyme.

Dark photon dark matter from a rolling inflaton [article]

Mar Bastero-Gil, Jose Santiago, Lorenzo Ubaldi, Roberto Vega-Morales
2021 arXiv   pre-print
We study in detail a recently proposed mechanism for producing non-thermal dark photon dark matter at the end of inflation in the mass range μ eV≲ m ≲ 10 TeV. A tachyonic instability induced by a rolling inflaton leads to the coherent production of dark (abelian) gauge bosons with a peak in the power spectrum corresponding to the Hubble scale at the end of inflation. As the Universe expands after inflation the dark photons redshift and, at some point in their cosmic evolution, they obtain a
more » ... . We focus in particular on the case where the dark photons are relativistic at the time their mass is generated and examine the associated cosmic evolution to compute the relic abundance today. We also examine the late time power spectrum demonstrating explicitly that it preserves the peak generated at the end of inflation. We show that the peak corresponds to small physical scales today, ℓ_ today∼ cm - 100 km, with large density fluctuations at ℓ_ today leading to a clumpy nature for the dark photon dark matter. We also discuss potential phenomenology and future directions, briefly commenting on the non-relativistic case.

Content value chains modelling using a copyright ontology

Roberto García, Rosa Gil
2010 Information Systems  
Existing Digital Rights Management systems, initiatives like Creative Commons or research works as some digital rights ontologies provide limited support for content value chains modelling and management. This is becoming a critical issue as content markets start to profit from the possibilities of digital networks and the World Wide Web. The objective is to support the whole copyrighted content value chain across enterprise or business niches boundaries. Our proposal provides a framework that
more » ... ccommodates copyright law and a rich creation model in order to cope with all the creation life cycle stages. The dynamic aspects of value chains are modelled using a hybrid approach that combines ontology-based and rule-based mechanisms. The ontology implementation is based on the Web Ontology Language (OWL-DL) and Description Logic reasoners are directly used for license checking. On the other hand, for more complex aspects of the dynamics of content value chains, rule languages are the choice.

Hybrid Index for Metric Space Databases [chapter]

Mauricio Marin, Veronica Gil-Costa, Roberto Uribe
2008 Lecture Notes in Computer Science  
We present an index data structure for metric-space databases. The proposed method has the advantage of allowing an efficient use of secondary memory. In the case of index entirely loaded in main memory our strategy achieves competitive performance. Our experimental study shows that the proposed index outperforms other strategies known to be efficient in practice. A valuable feature of the proposal is that the index can be dynamically updated once constructed.
