Use of libraries to access new chemical space: Applications to CRTH2

The generation of novel CRTH2 ligands in heavily congested chemical space, by de novo design of libraries is disclosed. Novel (1719) compounds across seven libraries were synthesised. More than 100 of these compounds showed binding potency a viable one.

RADIATION-SENSITIVE COMPOSITION

A radiation-sensitive composition containing a resist compound having a high sensitivity, a high resolution, a high etching resistance, and a low outgas which forms a resist pattern with a good shape is described. Further described is a method of forming a resist pattern using the radiation-sensitive composition. Still further described are a novel composition for forming a photoresist under coat film which is excellent in optical properties and etching resistance and contains substantially no sublimable substance and an under coat film formed by the composition. Still further described are a radiation-sensitive composition containing a solvent and a cyclic compound having a specific structure, for example, a cyclic compound (A) having a molecular weight of 700 to 5000 which is synthesized by the condensation reaction of a compound having 2 to 59 carbon atoms and 1 to 4 formyl groups (aldehyde compound (A1)) with a compound having 6 to 15 carbon atoms and 1 to 3 phenolic hydroxyl groups (phenol compound (A2)), and a cyclic compound for use in the radiation-sensitive composition.

Partially protected novel trisphenols and process for production thereof

The invention provides a partially protected trisphenol having the general formula (I) wherein R1is an alkyl group of 1-4 carbons or an alkoxyl group of 1-4 carbons, R2is an alkyl group of 1-6 carbons or a cycloalkyl group of 5 or 6 carbons, X1is a hydrogen atom, an alkoxycarbonylmethyl group wherein the alkyl group has 1-4 carbons, an alkoxycarbonyl group wherein the alkyl group has 1-4 carbons or a tetrahydropyranyl group, X2is a hydrogen atom, an alkoxycarbonylmethyl group wherein the alkyl group has 1-4 carbons, an alkoxycarbonyl group wherein the alkyl group has 1-4 carbons or a tetrahydropyranyl group, provided that when X1is a hydrogen atom, X2is not a hydrogen atom, and when X2is a hydrogen atom, X1is not a hydrogen atom; and m is an integer of 0, 1 or 2, and n is an integer of 0, 1, 2 or 3.
