Abstract: The invention provides a method, composition and kit for treating T-cell mediated diseases, degenerative joint diseases or diseases mediated by platelet activating factor (PAF) comprising administering to an animal in need thereof, an effective amount a pharmaceutical composition containing N-acetyl-kynurenine (NAK) or pharmaceutically acceptable salts thereof as the active ingredient.

Abstract: The invention provides a method of treating T-cell mediated diseases and a method of inhibiting the activation of T-cells using certain diketopiperazines. The invention also provides methods of synthesizing diketopiperazines and pharmaceutical compositions comprising certain diketopiperazines. The invention further provides methods of making improved pharmaceutical compositions of proteins and peptides by either increasing or decreasing the content of diketopiperazines in the compositions and the resultant improved pharmaceutical compositions.

Abstract: The present disclosure provides a method of treating a disease associated with a respiratory virus. The method comprises administering an effective amount of a pharmaceutical composition prepared by removing albumin from a solution of a human serum albumin composition and/or comprising a diketopiperazine with amino acid side chains of aspartic acid and alanine (DA-DKP), such as a low molecular weight fraction of human serum albumin. The present disclosure also provides a pharmaceutical product as well as a kit comprising DA-DKP.

Abstract: The invention provides a method of inhibiting vascular hyperpermeability in an animal in need thereof. The method comprises administering a vascular-hyperpermeability-inhibiting amount of a danazol compound to the animal. The method comprises administering an effective amount of a danazol compound to the animal accounting for the body fat content of the animal. The invention also provides a method of modulating the cytoskeleton of an endothelial cell in an animal.

Abstract: The invention provides a method of inhibiting the effects of platelet activating factor (PAF). For instance, a disease or condition mediated by PAF (particularly inflammation) can be treated or platelet aggregation can be inhibited. The invention also provides a method of inhibiting the production and/or release of interleukin 8 (IL-8) by cells. The effects of PAF and the production and/or release of IL-8 are inhibited according to the invention by a compound of the formula: wherein R1 and R2 are defined in the application, or a physiologically-acceptable salt thereof. The invention also provides pharmaceutical compositions comprising these compounds.
