New and useful phenylalkylcarbohydroxamic acids are disclosed of the formula ##STR1## wherein: (a) R is selected from the group consisting of alkoxy of one to six carbon atoms, alkenyloxy of two to six carbon atoms, alkyl of one to six carbon atoms, and benzyloxy; (b) R.sub.1 and R.sub.2 are each selected from the group consisting of hydrogen, alkoxy of one to six carbon atoms, alkenyloxy of two to six carbon atoms, alkyl from one to six carbon atoms, and benzyloxy; (c) R.sub.3 and R.sub.4 are selected from the group consisting of hydrogen or alkyl of one to six carbon atoms; (d) R.sub.5 is hydrogen or R.sub.5 together with R.sub.3 or R.sub.4 represent methylene; and (e) n signifies the number 0 to 1, and non-toxic salts thereof, which novel compounds exert a pronounced inhibition of blood platelet aggregation and accelerate the disaggregation of platelet aggregates already formed.
Cyclic amides are inhibitors of tumor necrosis factor and can be used to combat cachexia, endotoxic shock, and retrovirus replication. A typical embodiment is 3-phenyl-3-(1-oxoisoindolin-2-yl)propionamide.
Phenethylsulfones substituted in the position .alpha. to the phenyl group with a 1-oxoisoindoline or 1,3-dioxoisoindoline group reduce the levels of TNF.alpha. in a mammal. Typical embodiments are 2-[1-(3-ethoxy-4-methoxyphenyl)-2-methylsulfonylethyl]-4-aminoisoindoline- 1,3-dione and 2-[1-(3-cyclopentyloxy-4-methoxyphenyl)-2-methylsulfonylethyl]isoindoline- 1,3-dione.
Novel aryl amides are inhibitors of tumor necrosis factor .alpha. and can be used to combat cachexia, endotoxic shock, and retrovirus replication. A typical embodiment is N-benzoyl-3-amino-3-(3',4'-dimethoxyphenyl)propanamide.
Imido and amido substituted alkanohydroxamic acids reduce the levels of TNF.alpha. and inhibit phosphodiesterase in a mammal. A typical embodiment is 3-(3-cyclopentyloxy-4-methoxyphenyl)-N-hydroxy-3-phthalimidopropionamide.
Novel amides and imides are inhibitors of tumor necrosis factor.alpha. and phosphodiesterase and can be used to combat cachexia, endotoxic shock, retrovirus replication, asthma, and inflammatory conditions. Typical embodiments include 3-(1,3-dioxobenzo[f]isoindol-2-yl)-3-(3-cyclopentyloxy-4-methoxyphenyl)pro pionamide and 3-(1,3-dioxo-4-azaisoindol-2-yl)-3-(3,4-dimethoxyphenyl)propionamide.
