摘要:
Ricin A-chain is an N-glycosidase that attacks ribosomal RNA at a highly conserved adenine residue. Crystallographic studies show that not only adenine and formycin, but also pterin-based rings can bind in the ricin active site. For a better understanding of the recognition mode between ricin, and adenine-like rings, the interaction energies and geometries were calculated for a number of complexes. Shiga toxin, a compound essentially identical to the protein originally isolated from Shigella dysenteniae, has an active protein chain that is a homologue of the ricin active chain, and catalyzes the same depurination reaction. The present invention is drawn to identifying inhibitors of ricin and Shiga toxin, using methods molecular mechanics and ab initio methods and using the identified inhibitors as antidotes to ricin or Shiga toxin, or to facilitate immunotoxin treatment by controlling non-specific cytotoxicity.

The present application relates to a process for the manufacture of pigmented vitreous materials, as well as to pigmented vitreous materials, characterized by the use of soluble pigment precursors and preferably the absence of significant amounts of dispersants. These pigmented vitreous materials can be used as coloured materials for any known purposes. Soluble pigment precursors comprising a partial structure: are also claimed, wherein X1 is an aromatic or heteroaromatic ring, B is hydrogen or a group of the formula: but at least one group B is not hydrogen, and L is a solubilizing group.
摘要:
Novel macrocyclic compounds are constructed to include a ring or ring system having two bridgehead atoms with a bridge extending between the bridgehead atoms. Located in at least the bridge are two or more nitrogenous moieties that are derivatized with chemical functional groups. The ring or ring systems can include further nitrogenous moieties, either as ring atoms or on pendant groups attached to the ring. These can also be derivatized with chemical functional groups. The totality of the chemical functional groups imparts certain conformational and other properties to the compounds. In accordance with certain embodiments of the invention, libraries of such compounds are prepared utilizing permutations and combinations of the chemical functional groups and the nitrogenous moieties to build complexity into the library.

摘要:
A process is disclosed for the direct preparation of pigmentary 1,4-diketopyrrolo-[3,4-c]pyrroles of the formula (I) wherein each of R1 and R2 independently of the other is an isocyclic or heterocyclic aromatic radical, which process comprises heating an appropriate molar ratio of a disuccinate with a nitrile of the formula (II) R1—CN (II) or of the formula (III) R2—CN (III) or with mixtures of said nitrites, in an organic solvent and in the presence of a strong base and an effective amount of a selected particle growth inhibitor of formula (IV)-(X), and then obtaining the compound of formula (I) from the reaction product by protolysis. The process yields pigmentary 1,4-diketopyrrolo-[3,4-c]pyrroles directly, i.e., without the need for additional particle-size reducing aftertreatments. Also disclosed is a composition comprising a pigmentary 1,4-diketopyrrolo-[3,4-c]pyrrole and the particle growth inhibitor. These pigment compositions are useful for pigmenting high molecular weight organic materials.
