molecules with novel skeletons, but also to identify the enzymes that catalyze diverse chemical reactions. Exploring the substrate promiscuity and catalytic mechanism of those biosynthetic enzymes facilitates the development of potential biocatalysts. SfaB is an acyladenylate‐forming enzyme that adenylates a unique building block, 3‐isocyanobutanoic acid, in the biosynthetic pathway of the diisonitrile

Combinations of a carrier and a complex consisting of a nucleic acid molecule and a copolymer are described, wherein the copolymer consists of an amphiphilic polymer, preferably polyethylene glycol, and a charged effector molecule, in particular a peptide or peptide derivative, as well as their use for the transfer of nucleic acid molecules into cells.
The synthesis and structure-activity relationship of a series of mercaptoacylamino acids are described. These compounds were tested for antihypertensive activity. When the compounds were screened as angiotensin I-converting enzyme inhibitors in vitro, N-(2-mercaptopropanoyl)-L-cysteine-a (7a) and N2-(2-mercaptopropanoyl)-L-tryptophan-a (20a) were found to be 10 and 20 times more active than tiopronin, respectively.
本文描述了一系列巯基氨基酸的合成和结构-活性关系。对这些化合物进行了抗高血压活性测试。在将这些化合物作为血管紧张素 I 转换酶抑制剂进行体外筛选时,发现 N-(2-巯基丙酰基)-L-半胱氨酸-a(7a)和 N2-(2-巯基丙酰基)-L-色氨酸-a(20a)的活性分别是硫普罗宁的 10 倍和 20 倍。
