The present invention relates to a process for preparing (meth)acrylic acid, characterized in that a cyclic ester is converted to (meth)acrylic acid in the presence of a catalyst. The (meth)acrylic acid prepared can in particular be converted to (meth)acrylates.
The present invention relates to a process for preparing tetramethylglycolide by heating a composition which comprises at least 50% by weight of 2-hydroxy-isobutyric acid and/or tetramethylglycolide to a temperature of at least 100° C.
The invention relates to a cell which has been genetically modified so as to be capable of producing more 2-hydroxyisobutyric acid or more polyhydroxyalkanoates containing 2-hydroxyisobutyric acid monomer units than its wild type, characterized in that 2-hydroxyisobutyric acid or polyhydroxyalkanoates containing 2-hydroxyisobutyric acid monomer units are produced via acetoacetyl-coenzyme A as intermediate and 3-hydroxybutyryl-coenzyme A as precursor.
本发明涉及一种经过基因修饰的细胞,与野生型相比,该细胞能够产生更多的 2-羟基异丁酸或含有 2-羟基异丁酸单体单元的更多的聚羟基烷酸酯,其特征在于 2-羟基异丁酸或含有 2-羟基异丁酸单体单元的聚羟基烷酸酯是通过乙酰乙酰辅酶 A 作为中间体和 3-羟基丁酰辅酶 A 作为前体产生的。

The present disclosure relates to bifunctional compounds, which find utility as modulators of FLT3 (target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a Von Hppel-Lindau, cereblon, ligand which binds to the E3 ubiquitin ligase and on the other end a moiety which binds the target protein FLT3, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of the target protein. Diseases or disorders that result from aggregation or accumulation of the target protein are treated or prevented with compounds and compositions of the present disclosure.
本公开涉及双功能化合物,它们可用作 FLT3(靶蛋白)的调节剂。特别是,本公开涉及双功能化合物,其一端含有与 E3 泛素连接酶结合的 Von Hppel-Lindau(脑龙)配体,另一端含有与靶蛋白 FLT3 结合的分子,从而将靶蛋白置于泛素连接酶附近,以实现对靶蛋白的降解(和抑制)。本公开物具有与降解/抑制靶蛋白相关的广泛药理活性。本公开的化合物和组合物可以治疗或预防因目标蛋白聚集或积聚而导致的疾病或失调。
