The preparation of a collection of 131 small molecules, reminiscent of families of long chain N-acyl tyrosines, enamides and enol esters that have been isolatedfromheterologous expression of environmentalDNA (eDNA) in Escherichia coli, is reported. The synthetic libraries of N-acyl tyrosines and their 3-keto counterparts were prepared via solid-phase routes, whereas the enamides and enol esters
据报道,制备了 131 个小分子的集合,让人联想到长链 N-酰基酪氨酸、烯酰胺和烯醇酯家族,这些分子是从大肠杆菌环境 DNA (eDNA) 的异源表达中分离出来的。N-酰基酪氨酸及其3-酮对应物的合成库是通过固相途径制备的,而烯酰胺和烯醇酯是在溶液相中合成的。

combination of organic synthesis, chemical proteomics, biophysics, and cell and molecular biology investigations reveals that the natural product melophlin A (purple) influences signal propagation through the Ras network by interfering with the function of dynamins (green) in endocytosis.
