  • Patent number: 8193156
    Abstract: 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.
