CAS: 25830-77-7; (S)-2-(2,6-Dioxotetrahydro-2H-Pyran-3-yl)Isoindoline-1,3-Dione

该化合物是L-glutamic酸的一种化学化合物,其特点是存在一个phathaly类组,该化合物一般是白色的,是白色的,是白色的,以其在有机合成中,特别是在peptide合成和修改中作为试剂的作用而著称.它是一种碳氢化合物,这意味着它可以与氨等核分子发生反应,形成氨化物.phathalyl 组的存在会增加其在有机溶剂中的再活性和溶性.N-phathalyl-L-glutamic anydined也用于各种衍生物的制作,并且可以作为浸泡物合成氨基酸的保护组.它在标准实验室条件下的稳定性使它成为合成有机化学的一种有价值的化合物.但是,与许多化学物质一样,在处理时应采取适当的安全措施,因为如果浸入或浸入,可能会对健康构成危险.

摘要:N,N-Phthalyl-L-谷氨酸酐是 Y-谷氨酰化的关键试剂.通过使用受邻苯二甲酰基保护的化合物,已成功建立了合成谷氨酰胺酸和谷氨酰胺肽的有用途径.邻苯二甲酰基部分优先选择苯甲氧基作为保护基团,因为已知适当的 L-谷氨酸酐与胺的开环会产生具有前一种保护基团的 γ-谷氨酰衍生物,而与后者产生 α-谷氨酰产物.通常,邻苯二甲酰亚胺是通过将氨基酸和邻苯二甲酸酐的混合物加热至略高于酸酐的熔点来制备的.但是从l-谷氨酸中得到的产物从水中结晶时不纯冷凝

摘要:Disclosed is a novel synthetic method for isomeric peptides through an appropriate linkage of L-selenomethionine or Se-Methyl-L-selenocysteine with L-glutamic acid. The novel synthetic method produces isomeric peptides of L-selenomethionine or Se-Methyl-L-selenocysteine that exhibit (i) enhanced water solubility; (ii) enhanced rate of dissolution in water; (iii) enhanced bioavailability; (iv) excellent vascular endothelial growth factor promoting activity; (v) excellent anti-5-alpha-reductase activity; (vi) capabilities to prevent/reduce “hair fall†and promote “hair growth†, thereby maintaining a perfect homeostasis for “hair care†. Cosmeceutical and pharmaceutical compositions comprising the isomeric peptides obtained through an appropriate linkage of L-selenomethionine or Se-Methyl-L-selenocysteine with L-glutamic acid are also disclosed. Other dipeptides with several other amino acids and uses thereof are also disclosed.
