What is disclosed are steroid-21-halogeno-17-(alkyl carbonates), useful as medicaments for the treatment of inflammatory dermatoses, and a method for making them.

Corticoid-17-(alkyl carbonates) and process for their manufacture

What is disclosed is corticoid 17-(alkyl carbonates) of the formula ##STR1## as defined in the specification, which compounds can be used in veterinary therapy and human therapy, in the form of suspensions, ointments, creams, sprays and the like, for the treatment of inflammatory dermatoses of very diverse cause.

Corticoid 17-(alkyl carbonates) and processes for their preparation

Compounds of formula I ##STR1## wherein R.sup.1 and R.sup.1' are identical or different and represent hydrogen, an alkyl radical or alkoxy radical having 1-4 carbon atoms, the allyl group, a halogen atom or the nitro group, R.sup.2 represents an acrylic acid radical or an acrylic acid nitrile radical of the formulae ##STR2## wherein R.sup.5 represents hydrogen, an alkyl radical having 1-5 carbon atoms, an aryl radical or aryl-lower alkyl radical either unsubstituted or substituted by lower alkyl or alkoxy, R.sup.6 represents hydrogen or an alkyl radical having 1-8 carbon atoms, R.sup.7 represents hydrogen, a lower alkyl radical or an aryl-lower alkyl radical, R.sup.3 and R.sup.4 represent together with the nitrogen atom a heterocyclic ring with 5-7 members being optionally substituted by C.sub.1 -C.sub.4 alkyl, in which ring one carbon atom may be replaced by one oxygen atom, sulfur atom or one further nitrogen atom, the latter may be substituted, or wherein R.sup.3 represents hydrogen and R.sup.4 represents a phenyl-alkylene or phenyl-alkylidene radical of the formula ##STR3## in which Alk is alkyl having 1 to 3 carbon atoms, and n is a figure from 1-3, and R.sup.8 and R.sup.9 are identical or different and represent hydrogen, an alkoxy radical having 1-3 carbon atoms or the benzoyl radical or R.sup.8 and R.sup.9 represent together the bismethylene dioxy radical, as well as the physiologically compatible acid addition salts and a process for preparing these compounds.

1-Aryloxy-2-hydroxy-3-aminopropanes

Cyclic 2',3'-ethers of 3-hydroxy-14,15.beta.-oxido-14.beta.-bufa-4,20,22-trienolide, 3.beta.-(.alpha.-L-rhamnopyranoside) and process for preparing them. The compounds have a strongly positive inotropic activity and may be used in the therapy of cardiac insufficiency.

Heart glycosides and process for preparing them

Digoxigenine-3-[2', 3'-didesoxy-glycosides] of the formula ##SPC1## In which R.sup.1 is the digoxigenine radical and R.sup.2 is hydrogen, methyl or --CH.sub.2 OH, which are prepared by a reaction of a digoxigenine-12-monoacylate with an acylated 1,2-glycal, a catalytic hydrogenation of the 12-acylates obtained and a subsequent hydrolysis. The products have a cardiotonic, diuretic and especially venotonic activity.

Digoxigenine-3-[2',3'-didesoxy-glycosides] and a process for their

12-Dehydro digoxin mono-4'' and 3''-alkyl ethers and a process for their manufacture. The compounds have a cardiotonic and diuretic activity.
