A class of propyl cationic peptide lipids is propyl cationic peptide lipid compounds having a general formula structure as follows. After the propyl cationic peptide lipids are dispersed in water, a cationic liposome with a particle size of approximately 100 nm is obtained. The cationic liposome can carry plasmid DNA (pDNA) or small interfering RNA (siRNA) into cells to realize the function of gene delivery, and is almost non-toxic to the cells.

Provided are artificially synthesized modified mono-methylated lysines and modified mono-methylated lysine derivatized polypeptides. Also provided is an antibody produced by using this modified mono-methylated lysine and modified mono-methylated lysine derivatized polypeptide as an antigen, the antibody can be used in recognizing and enriching the modified polypeptide after the lysine mono-methylated polypeptide being derivatized in vitro. Also provided are a preparation method of said antibody, a method for identifying and quantifying the lysine mono-methylated modified substrate in cell or tissue by using proteomics approach of affinity enrichment for specific antibody and mass spectrometry.
Oligonucleotide-folate conjugates are described wherein folates are conjugated to one or more sites on an oligonucleotide including the 2′-, 3′-, 5′-, nucleobase and internucleotide linkage sites. The folate can be attached via the &agr;- or &ggr;-carboxylate, optionally through a linking group. Methods for the regiospecific synthesis of the conjugates are diclosed. Also disclosed are nucleosidic and non-nucleosidic linkers conjugated to folic acid and related folates.

Template-fixed β-hairpin peptidomimetics of the general formulae (1), wherein Z is a template-fixed chain of 7 to 11 α-amino acid residues which, depending on their positions in the chain (counted starting formteh N-terminal amino acid) are Gly, or Pro, or of certain types which, as the remaining symbols in the aove formulae, are defined in the description and the claims, and salts thereof, have the property to inhibit proteases, in particular serine proteases. These β-hairpin peptidomimetics can be manufactured by a process which is based on a mixed solid- and solution phase synthetic strategy.
