专利号:US-2022089618-A1 优先权日:2019-01-29 标题:Solid-State Synthesis Of Precursors Of Metal-Organic Frameworks 发明人:MAJANO GERARDO J; FALKOWSKI JOSEPH M 权利人:EXXONMOBIL RES & ENG CO 摘要:Metal-organic frameworks (MOFs) are highly porous entities comprising a multidentate ligand coordinated to multiple metal atoms, typically as a coordination polymer. MOFs are usually produced from a solvent in powder form under hydrothermal or solvothermal synthesis conditions. Alternately, powder-form precursors of MOFs may be formed by milling or mulling a substantially solid mixture of a metal salt and a multidentate organic ligand, optionally in the presence of a small amount of a solvent. The powder-form precursors may then undergo heating, typically in the absence of applied shear, to produce the corresponding MOF. Mulling may be differentiated from milling at least in that mulling applies to the substantially solid mixture at a non-constant pressure and milling applies a constant pressure while forming the powder-form precursor. In some cases, mulling may promote more effective formation of the powder-form precursor compared to milling.

专利号:WO-9729091-A1 优先权日:1996-02-09 标题:Balanol analogues 发明人:NIELSEN JOHN; LYNGSOE LARS OLE 权利人:AUDA PHARMACEUTICALS APS; NIELSEN JOHN; LYNGSOE LARS OLE 摘要:The present invention relates to a solid phase methodology for the preparation of a combinatorial library of structural analogues of the natural product balanol (ophiocordin, azepinostatin), which is a protein kinase C (PKC) and protein kinase A (PKA) inhibitor. The method comprises solid-phase synthesis of the analog variants of balanol whereby a high molecular diversity is introduced. The synthetic scheme is based on a retrosynthetic analysis of the native structure which revealed three main building blocks suitable as templates for modification. The dicarboxy-functional moiety can be immobilised to the polymer support either as the monoallyl ester or as the internal anhydride. The libraries produced by the method are especially suited for high throughput screening of potential drug candidates for the treatment of mammals, especially humans.
