Abstract: The present invention relates to derivatives of L-Tyrosyl-L-Arginine and the use of said derivatives in the prevention and/or treatment of a tau-induced cytotoxicity.

Abstract: The present invention relates to novel linear peptides with antimicrobial activity. Said peptides are made up of 11 amino acids, and they have the amino group of the amino acid constituting the N-terminal end in a non-derived form or functionalized with an acetyl group, p-toluene sulphonyl, benzyl or benzoyl. The amino acid constituting the C-terminal end of said peptides is in carboxamide form. The invention describes the synthesis and use of said peptides as antimicrobial agents to combat pathogenic bacteria for plants. The invention also relates to compositions containing said peptides and an auxiliary agent, and to a method for preventing and treating infections and diseases of plants caused by pathogenic bacteria.

Abstract: The present invention relates to a compound of formula (I) wherein X is hydrogen, R1, R1C(O), R1CO2, or a COX2 inhibitor, wherein R1 is C1-20 alkyl, aryl, arylalkyl, alkyloxy or arylalkyloxy; wherein Y is OR2, NHR3N(R3)2, or a COX inhibitor; wherein R2 is hydrogen or C1-20 alkyl and each R3 is independently hydrogen or a C1-4 alkyl; wherein T is OR4, NHR5N(R5)2, or a COX inhibitor wherein R4 is hydrogen or C1-20 alkyl and each R5 is independently hydrogen or a C1-4 alkyl; wherein Z is hydrogen, R6, R6C(O), R6CO2, or a COX2 inhibitor; wherein R6 is C1-20 alkyl, aryl, arylalkyl, alkyloxy or arylalkyloxy; with the proviso wherein when X and Z are hydrogen and T is OH, Y is not OH; for use in the prevention and/or treatment of pain wherein said compound is provided for systemic administration.
