Material: Für die Suche nach Leitstrukturen für Gd-KM wurden über 250000 Moleküle (MW:500-900Da) aus kommerziellen Datenbanken untersucht. Auswahlkriterium war die möglichst große Übereinstimmung mit einem Pharmakophormodell, das auf der Basis von 6 bekannten Gd-Kontrastmitteln erstellt wurde. Zur Berechnung dieses Modells sowie zur Ähnlichkeitsbewertung der untersuchten Strukturen wurde die Software COFEA verwendet. Kern dieses Programms ist ein neuer molekularer Deskriptor, die CFM. Ergebnisse: Die 16 ermittelten Verbindungen gehören zu drei verschiedenen strukturellen Klassen, die sowohl neue zyklische und lineare, als auch verzweigte Gd-Bindungsstellen aufweisen. Die Zentren der 4 zyklischen Verbindungen (MW:604-913Da) enthalten 2 N- und 3 bzw. 4 O-Atome, während die unterschiedlichen Grundgerüste der zehn linearen Komponenten (MW:503-728Da) 4 bzw. 5 N-Atome besitzen. Die beiden verzweigten Strukturen (MW:577-644Da) enthalten 5 bzw. 6 N-Atome, die für eine mögliche Bindung von Gd3+ infrage kommen. Neben den polaren Gruppen der jeweiligen Zentren enthalten die Verbindungen zwischen 4 und 10 weitere polare oder geladene Gruppen. Schlussfolgerungen: Aufgrund der Möglichkeit zur Erstellung von Pharmakophormodellen ist die CFM besonders geeignet für die Suche nach neuen Leitstrukturen von Gd-KM. Zur Weiterentwicklung zu Kontrastmitteln mit spezifischen Eigenschaften werden unterschiedliche strukturelle Varianten erzeugt.}, page = {283}, project = {abt_zell, cheminformatics}, } |

Depending on the requirements, it is based on a distance or geometry matrix. Thus, the CFM permits topological and three-dimensional comparisons of molecules. In contrast to the common distance matrix, the CFM is based on features instead of atoms. Each kind of these features may be weighted separately, depending on its (estimated) contribution to the biological effect of the molecule. In this work, we show that the CFM allows us to adapt similarity evaluations to particular ligands as well as to classification requirements. The CFM method is analyzed regarding correctness, adaptivity and speed. Applying the basic setting of feature weights, the similarity evaluations using the CFM on the one hand and the Tanimoto coefficient together with MACCS Keys on the other yield similar results. However, in contrast to the latter method, the CFM even permits us to focus on small parts of molecules to serve as a basis for similarity. Accordingly, we have achieved striking results not only by readjusting the feature weights with regard to the scaffold but also to the side chain of the respective target. The results of the latter run turned out to be rather independent of the molecular scaffold. Hence, the CFM is suitable not only for common similarity evaluation, but also for techniques such as lead or scaffold hopping.}, doi = {10.1007/s00894-002-0110-0}, project = {abt_zell, cheminformatics}, publisher = {Springer}, url = {http://dx.doi.org/10.1007/s00894-002-0110-0}, } |

Depending on the particular purpose, the descriptor may be generated upon either topological or Euclidean molecular data. To assure a variable utilizability, the assignment of the structural patterns to feature types is arbitrarily determined by the user. This step is based on a graph algorithm for substructure search, which resembles the common substructure descriptors. While these merely allow a screening for the predefined patterns, the CFM permits a real substructure/subgraph search, presuming that all desired elements of the query substructure are described by the selected feature set. In this work, the CFM based substructure search is evaluated with regard to both the different outputs resulting from varying feature sets and the search speed. As a benchmark we use the programmable atom typer (PATTY) graph algorithm. When comparing the two methods, the CFM based matrix algorithm is up to several hundred times faster than PATTY and when using the CFM as a basis for substructure screening, the search speed is accelerated by three orders of magnitude. Thus, the CFM based substructure search complies with the requirements for interactive usage, even for the evaluation of several hundred thousand compounds. The concept of the CFM is implemented in the software COFEA.}, doi = {10.1007/s00894-003-0126-0}, project = {abt_zell, cheminformatics}, publisher = {Springer}, url = {http://dx.doi.org/10.1007/s00894-003-0126-0}, } |

A distance measure is the underlying property on which many neural models rely, for example self-organizing maps or neural gas.

This paper shows that a weaker measure, the similarity measure, is sufficient in many cases. As an example, similarity-based networks for strings are presented. Although a metric can also be defined on strings, similarity is the established measure in string-intensive research, like computational molecular biology.

For image decomposition we developed a fast non-iterative transform algorithm, in which the original image is processed with a 2D Gabor wavelet filter bank. We used the positions of the local extrema (low-level object features) in the filter responses to calculate a set of Gabor wavelet coefficients. That guarantees on the one hand a low redundancy of the resulting representation and on the other hand an automatic detection of the significant features in the image. To prove the quality of the object representation the image can be reconstructed from the descriptor. It was shown that such descriptors can be used for real-time scale invariant object tracking by gradient following or template adaptation. Tracking control was realized by a scale factor discriminator control technique and convolution based 2D cross-correlation. Our experiments revealed that this method enables real-time object or face tracking in a wide scale range and provides robustness against high frequency camera vibrations, from which cameras on mobile vehicles suffer.}, keywords = {Image Decomposition, Gabor Wavelets, Face Tracking}, project = {abt_zell, robotics}, url = {http://www.cogsys.cs.uni-tuebingen.de/mitarb/mojaev/documents/miroc2003.pdf}, } |
