摘要:
The present invention relates to novel compounds which possess a broad range of useful biological activities. These compounds can maintain, increase, or restore sensitivity of cells to therapeutic or prophylactic agents. They can also suppress, modify, or significantly reduce an immune response, including an autoimmune response in a mammal. This invention also relates to pharmaceutical compositions comprising these compounds. The compounds and pharmaceutical compositions of this invention are particularly well-suited for treatment of multi-drug resistant cells, for prevention of the development of multi-drug resistance, for use in multi-drug resistant cancer therapy, and for prevention or treatment of graft rejection and various autoimmune diseases.

This invention relates to a novel class of immunosuppressive compounds having an affinity for the FK-506 binding protein (FKBP). Once bound to this protein, the immunosuppressive compounds inhibit the prolyl peptidyl cis-trans isomerase (rotamase) activity of the FKBP and inhibit T cell activation. As such, the compounds of this invention can be used as immunosuppressive drugs to prevent or significantly reduce graft rejection in bone marrow and organ transplantations and for use in the treatment of a wide variety of autoimmune diseases in humans and other mammals.

Enzyme tripeptides of the formula: ##STR1## and analogs thereof which inhibit renin and are useful for treating various forms of renin-associated hypertension, hyperaldosteronism and congestive heart failure; compositions containing these renin-inhibitory peptides, optionally with other antihypertensive agents; and methods of treating hypertension, hyperaldosteronism or congestive heart failure or of establishing renin as a causative factor in these problems employing the novel tripeptides.
摘要:
An improved process for preparing .alpha.,.omega.-diamino acids, such as D,L-homolysine, 2,8-diaminooctanoic acid, ornithine, lysine, or the like, comprising reaction of phthalic anhydride and an amino alcohol in a hydrocarbon solvent; treatment of the resulting phthalimide--N--(CH.sub.2).sub.n --OH derivative, without isolation thereof, with phosphorus tribromide or phosphorous pentachloride; alkylation of diethyl acetamidomalonate with the phthalimide--N--(CH.sub.2).sub.n --chloride or --bromide of the previous step, in the presence of, particularly, sodium hydride/dimethylformamide; standard acid hydrolysis and decarboxylation; selective protection via copper(II) chelation, N-specific acylation with benzyl chloroformate, and decomposition of the amino acid-copper(II) complex with alkaline thioacetamide; standard t-butoxycarbonyl acylation; and deprotection to obtain the desired .alpha.,.omega.-diamino acids.
