In various aspects, the present invention relates to non-peptidic compounds, which modulate calcitonin and amylin receptor activity; to processes for the preparation of some such compounds; and to pharmaceutical compositions including such compounds. Compounds of the invention are useful as calcitonin and/or amylin agonists and in the treatment of bone diseases and metabolic diseases.
The present invention provides compounds of Formula (I): and salts, racemates, isomers, diastereoisomers, enantiomers, hydrates, solvates, N-oxides, pharmaceutically acceptable derivatives or prodrugs thereof. Also provided the use of these compounds as antibacterials, compositions comprising them and processes for their manufacture.

A polyamide acid composition for preparing a polyimide which can extend the pot life of the composition comprising a solution of a polyamide acid in an organic solvent, the polyamide acid being a precursor of the polyimide, a dehydrating agent, a catalyst and a pot life extending agent which can lower a rate of conversion of the polyamide acid to the plyimide, and the process for preparing the polyimide from said polyamide acid composition. According to the present invention the pot life can be extremely extended to give the composition an enough flowability for a long time without reducing the excellent properties such as a heat resistance and an electric insulation of the obtained polyimide.

A polyamide acid composition for preparing a polyimide which is improved in the stability in a form of solution and can extend the pot life of the composition comprising a solution of a polyamide acid in an organic solvent, the polyamide acid being a precursor of the polyimide, and an N-substituted heterocyclic compound as a chemical treating agent which can lower a rate of conversion of the polyamide acid to the polyimide. The pot life can be extremely extended to give the composition an enough flowability for a long time without reducing the excellent properties such as a heat resistance of the obtained polyimide.
The level of free formaldehyde in a polymer emulsion comprising an acrylamide cross-linking agent is reduced by the addition of a formaldehyde scavenger having the formula CH₃COCH₂CONR₂R₃ where R₂ and R₃ are H or lower alkyl. The emulsions are suitable for use in coating or binder compositions.
通过添加具有 CH₃COCH₂CONR₂R₃ 式中 R₂ 和 R₃ 为 H 或低级烷基的甲醛清除剂,可降低包含丙烯酰胺交联剂的聚合物乳液中的游离甲醛含量。乳液适用于涂料或粘结剂组合物。
