20090143545 | Thermosetting Poly(thio)urethane Formulation Comprising at Least One Block Copolymer and Use Thereof in Optics for the Production of Organic Lenses Having Improved Toughness - The invention relates to a polymerisable liquid mixture comprising: (a) a polymerisable thermosetting composition which is a precursor by polymerisation of a first thermoset polymer material, said composition containing at least one polythiol and/or one polyol, preferably a polythiol, and at least one polyiso(thio)cyanate; and (b) a second polymer material solubilised in the aforementioned polymerisable thermosetting composition, whereby the second material (i) contains at least one block copolymer comprising at least two polymer blocks A and B, namely an elastomer block A and a hydrophilic block B, and, following polymerisation of the polymerisable mixture, (ii) forms domains which are rich in elastomer block A and which are dispersed throughout the first material, said domains being smaller than 80 nanometers and preferably smaller than 50 nanometers. The invention also relates to a transparent article having improved toughness, which is produced by means of polymerisation of the above-mentioned polymerisable mixture, comprising an alloy of a first thermoset polymer material forming the matrix of said article and of a second polymer material which is dispersed throughout said first material. The aforementioned articles have improved resistance to impact and to crack propagation. The invention is suitable for use in ophthalmic optics. | 06-04-2009 |

20100286429 | CRYSTALLOGRAPHIC MODEL OF THE BINDING SITE AND A MODULATOR REGULATING THE CATALYTIC ACTIVITY OF PHOSPHOFRUCTOKINASE (PFK), A METHOD OF DESIGNING, SELECTING AND PRODUCING THE PFK MODULATOR, A COMPUTER-BASED METHOD FOR THE ANALYSIS OF THE INTERACTIONS BETWEEN THE MODULATOR AND PFK - The subject matters of the invention are: a crystallographic model of the binding site and a modulator regulating the catalytic activity of phosphofructokinase (PFK), a method of designing, selecting and producing a PFK modulator, a computer-based method for the analysis of the interaction between the modulator and PFK and for the analysis of molecular structures, a computer-based method of drug design, a method of assessing the ability of the potential modulator to interact in the binding site on the PFK surface, a method of providing data for generating structures and/or performing design for drugs that bind PFK, PFK homologues or analogues, complexes of PFK with a potential modulator, or complexes of PFK homologues or analogues with potential modulators, a computer system. | 11-11-2010 |
20110060574 | COMPUTER-BASED MODELING AND DESIGNING OF PHOSPHOFRUCTOKINASE 1 (PFK) MODULATORS - The subject matters of the invention are: a crystallographic model of the binding site and a modulator regulating the catalytic activity of phosphofructokinase (PFK), a method of designing, selecting and producing a PFK modulator, a computer based method for the analysis of the interaction between the modulator and PFK, a computer-based method the analysis of molecular structures, a method of assessing the ability of the potential modulator to interact in the binding site on the PFK surface, a method of providing data for generating structures and/or performing design for ligands binding PFK, PFK homologues or analogues, complexes of PFK with a potential modulator, or complexes of PFK homologues or analogues with potential modulators, a computer system. The invention makes it possible to design a suitable activator, which could be used to modulate PFK activity, taking advantage of PFKs capability to bind in its effector site phosphate groups or other groups with a similar potential to interact, which correspond with the substituents in positions 1, 2 and 6 of the fructose ring, or groups corresponding with positions of the fructose ring groups interacting in the PFK effector site. | 03-10-2011 |
