摘要:
HIV protease inhibitors, obtainable by chemical synthesis, inhibit or block the biological activity of the HIV protease enzyme, causing the replication of the HIV virus to terminate. These compounds, as well as pharmaceutical compositions that contain these compounds and optionally other anti-viral agents as active ingredients, are suitable for treating patients or hosts infected with the HIV virus, which is known to cause AIDS.

摘要:
A method to potentiate the effect of a chemotherapeutic agent in a tumor cell, which method comprises administering to said tumor cell, along with said chemotherapeutic agent, a potentiating amount of a compound of the formula: ##STR1## or an amide, ester or hybrid amide/ester thereof, wherein X is a hydrocarbon radical optionally substituted on any aromatic moiety contained therein; Y--CO is .gamma.-Glu or .beta.-Asp and AA.sub.C is an amino acid, preferably glycine, phenylglycine, .beta.-alanine, alanine or phenylalanine is disclosed. Similar compounds can also be used to selectively exert cytotoxicity versus target cells as compared to nontarget cells and also to elevate the production of GM progenitors in bone marrow of mammalian subjects.

摘要:
A homogeneous composition for forming on firing a film of precious metal, which is one or more of platinum, palladium, gold and silver, on a substrate, for instance to decorate table ware, comprises polymeric resin and a solution, in water and a co-solvent, of thiolate of the precious metal, the composition containing 3-22% by weight of the precious metal as the thiolate, and the co-solvent, resin and thiolate being such that as the composition on a substrate dries and is progressively heated in firing, the water evaporates off to leave a homogeneous composition of the resin and thiolate in the co-solvent, then the co-solvent evaporates off to leave a homogeneous composition of the thiolate in the resin, and then the thiolate decomposes to the precious metal while the resin volatilize.
