These compounds selectively target folate receptors (FR) of cancerous tumor cells and inhibit purine synthesis and hence, DNA synthesis.
专利号:US-8193156-B1 优先权日:2006-05-18 标 题:Dipeptides incorporating selenoamino acids with enhanced bioavailability—synthesis, pharmaceutical and cosmeceutical applications thereof 发明人:MAJEED MUHAMMED; NAGABHUSHANAM KALYANAM; RAMANUJAM RAJENDRAN; CHANDRAMOULI RENUKESHWAR H 权利人:MAJEED MUHAMMED; NAGABHUSHANAM KALYANAM; RAMANUJAM RAJENDRAN; CHANDRAMOULI RENUKESHWAR H; SAMI LABS LTD 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.
