Imidazoline I2 receptors (I2-IR), widely distributed in the CNS and altered in patients that suffer from neurodegenerative disorders, are orphans from a structural point of view, and new I2-IR ligands are urgently required for improving their pharmacological characterization. We report the synthesis and three-dimensional quantitative structure–activity relationship (3D-QSAR) studies of a new family

A deep cavitand catalyzes DielsâAlder reactions of bound maleimides via activation of the dienophile by interaction with the organized hydrogen bonding network at the cavitand rim. Rapid inâout exchange of reactant and product allows efficient turnover. The increase in steric bulk of the reaction product lessens its binding affinity, reducing (and in some cases completely eliminating) product inhibition.
A resin composition for three dimensional printing at elevated temperatures forming high temperature-resistant materials, the resin composition comprising a heat curable component A having one or more chemical species chosen from the group comprised of monomers and/or oligomers and/or prepolymers of maleimide derivatives according to formula and a light-curable component B having one or more chemical species chosen from the group comprised of (meth)acrylate, (meth)acrylamide, vinyl esters, vinyl ether, vinyl, allyl, alkinyl or styrenic compounds as well as derivatives thereof substituted with at least one molecule from the group from which component A is chosen, wherein the amount of component A ranges from 30 wt % to 95 wt % based on the total weight of components A and B and the amount of the light-curable component B ranges from 5 to 70 wt %, based on the total weight of components A and B.
