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.
揭示了一种新颖的合成方法,通过将L-硒代蛋氨酸或Se-甲基-L-硒蛋氨酸与L-谷氨酸适当连接,制备L-硒代蛋氨酸或Se-甲基-L-硒蛋氨酸的同分异构肽。这种新颖的合成方法产生的同分异构肽具有以下特点:(i)增强的水溶性;(ii)在水中溶解速度增强;(iii)增强的生物利用度;(iv)出色的血管内皮生长因子促进活性;(v)出色的抗5α-还原酶活性;(vi)具有预防/减少“脱发”和促进“头发生长”的能力,从而维持“头发护理”的完美稳态。还揭示了包括通过将L-硒代蛋氨酸或Se-甲基-L-硒蛋氨酸与L-谷氨酸适当连接获得的同分异构肽的化妆品和药用组合物。还揭示了包括其他多种氨基酸的二肽及其用途。
