Morpholino oligomers containing both uncharged and cationic intersubunit linkages are provided. The oligomers are oligonucleotide analogs containing predetermined sequences of base-pairing moieties. The presence of the cationic intersubunit linkages in the oligomers, typically at a level of about 10-50% of total linkages, provides enhanced antisense activity, in various antisense applications, relative to the corresponding uncharged oligomers. Also provided are such oligomers conjugated to peptide transporter moieties, where the transporters are preferably composed of arginine subunits, or arginine dimers, alternating with neutral amino acid subunits.

A pharmaceutical composition consisting of identical repeating units, each unit having a charge motif composed of a positively charged free amino moiety and a negatively charged moiety, wherein the positively charged free amino moiety and the negatively charged moiety of each charge motif are separated by at least one neutral amino acid, and wherein the positively charged free amino moiety of one of the charge motifs is separated by a distance of at least 8 amino acids from the positively charged amino moiety of another charge motif, and a pharmaceutically acceptable carrier. Said pharmaceutical composition is useful for inducing IL-2, activating T cells to produce a T helper 1 cytokine profile, suppressing IgG antibody response to specific antigen, promoting allograft survival, reducing postoperative surgical adhesion formation, and / or protecting against abscess formation associated with surgery, trauma or diseases that predispose the host to abscess formation.

The present invention relates to methods for the prevention and treatment of chronic inflammatory diseases, cancer, and involuntary weight loss. In the practice of the present invention patients are enterally administered HMB alone or alternatively in combination with eicosapentaenoic (20:5 ω-3), FOS, carnitine and mixtures thereof. HMB may be added to food products comprising a source of amino-nitrogen enriched with large neutral amino acids such as leucine, isoleucine, valine, tyrosine, threonine and phenylalanine and substantially lacking in free amino acids.

An object of the invention is to provide an antimicrobial peptide having an amino acid sequence which is different from a peptide existing and functioning as an antimicrobial peptide in the natural world and is not based on the conventional developmental approach for an antimicrobial peptide-containing antimicrobial agent, and a polynucleotide coding for said peptide. Another object is to provide an antimicrobial agent which contains such an antimicrobial peptide. Namely, an antimicrobial peptide represented by a general formula (1)(Xa)n-S  (1)wherein Xa of the formula (1) is a hydrophilic amino acid residue, n is an integer of from 1 to 6, two or more of the Xa may be the same or different from one another, S is a peptide represented by hydrophobic amino acid part-basic amino acid part-bridge part-basic amino acid part-hydrophobic amino acid part, and amino acid residue of the bridge part is selected from the group consisting of hydrophobic amino acids and neutral amino acids.

A detergent composition which comprises (A) an N-(long-chain acyl) neutral amino acid or a salt thereof, (B) an N-(long-chain acyl) neutral amino acid dipeptide or a salt thereof, and (C) an N-(long-chain acyl) neutral amino acid tripeptide or a salt thereof at a specific weight ratio and which is excellent in the ability to foam and foam retention and usable in washing the body or the hair to make it nongreasy and moist through drying; a detergent composition which contains (D) a higher fatty acid having 8 to 22 carbon atoms or a salt thereof at a specific weight ratio in addition to the above three components and which is enhanced in the creaminess of foam; and a process for the production of N-(long-chain acyl) neutral amino acids or salts thereof which comprises mixing a neutral amino acid with a long-chain fatty acid and at least one alkali substance selected from between sodium hydroxide and potassium hydroxide and keeping the obtained mixture under heating, if necessary, in an inert gas atmosphere, while continuously removing water formed by the reaction and which process permits the progress of dehydrative condensation at relatively low temperature in a short time and enables efficient production of N-(long-chain acyl) neutral amino acids or salts thereof without any catalyst.
