Through the use of computational modeling, a series of pyrimidinetrione-based inhibitors of MMP-13 was designed based on a lead inhibitor identified through file screening. Incorporation of a biaryl ether moiety at the C-5 position of the pyrimidinetrione ring resulted in a dramatic enhancement of MMP-13 potency. Protein crystallography revealed that this moiety binds in the S(1)(') pocket of the enzyme

An efficient copper-catalyzed solvent-switchable regioselective 1,2- or 1,6-addition of quinones with boronic acids has been developed. This novel catalytic protocol for the synthesis of various quinols and 4-phenoxyphenols was enabled by a simple solvent swap between H2O and MeOH. It features mild reaction conditions, simple and easy operation, broad substrate scope and excellent regioselectivity
已经开发出一种有效的铜催化溶剂可转换的醌与硼酸的区域选择性 1,2-或 1,6-加成反应。这种用于合成各种对苯二酚和 4-苯氧基苯酚的新颖催化方案是通过 H 2 O 和 MeOH 之间的简单溶剂交换实现的。其具有反应条件温和、操作简单易行、底物范围广、区域选择性优良等特点。还成功地研究了克级反应以及两种加成产物的进一步转化。

The present invention provides compounds of the general formula:-
wherein R is a hydrogen or halogen atom, a hydroxyl group or a lower alkyl or lower alkoxy radical, R2 is a hydrogen atom or a lower alkyl or acyl radical, R3 is an alkylene or lower alkenylene radical, optionally substituted by cyano, amino or protected amino group, and X is 0, S, SO or SO2, the derivatives thereof on the carboxyl group; and the pharmaceutically acceptable salts thereof.
The present invention also provides processes for preparing these compounds and pharmaceutical compositions containing them.
An improved process for producing aromatic polyethers by condensation polymerizing aromatic dihydroxy compounds represented by the general formula: HO-Ar-OH and aromatic dichloro compounds represented by the general formula: Cl-Ar¹-Y-Ar²-Cl, or condensation polymerizing monohydroxymonochloro aromatic compounds represented by the general formula: HO-Ar¹-Y-Ar²-Cl in the above formulae, Ar, Ar¹, Ar² are as defined in the specification) in the presence of alkali metal compounds comprising a combination of alkali metal carbonates comprising carbonate and/or hydrogencarbonate of an alkali metal, e.g., potassium, and alkali metal fluorides.
In accordance with the present process, high molecular weight aromatic polyethers can be efficiently produced from aromatic chloro compounds which are inexpensive and easily available.
