Abstract: The present invention relates to novel 7-substituted benzopyranes of formula (I), whereinR.sub.1 and R.sub.2 are hydrogen, alkyl of from 1 to 6 carbon atoms, hydroxyalkyl, alkenyl, cycloalkyl, phenylalkyl, dimethoxy-phenylalkyl, or R.sub.1 and R.sub.2 together with the joining nitrogen atom may represent a 5-7-membered heterocyclic ring,R.sub.3 is hydrogen, alkyl of from 1 to 4 carbon atoms or phenyl,R.sub.4 is hydrogen,R.sub.5 is hydrogen or phenyl, orR.sub.4 and R.sub.5 together may represent a bonding electron pair between the second and the third carbon atoms of the benzopyrane ring,R.sub.6 and R.sub.7 are hydrogen or they may represent an oxygen atom together,n is 1 or 2,with the proviso, that the pyrane ring may bear only one alkyl or phenyl substituent, and preparation process thereof.The novel compounds have valuable therapeutical effects, mainly in cardiotherapy.

Abstract: An animal feed containing 0.00002 to 0.1% by weight of:2-methyl-7-methoxy-4'-nitroisoflavone,7-[hydroxyethoxy]-2-methylisoflavone,7-carbethoxy-2-methylisoflavone,7-ethoxyisoflavone,7-n-benzyloxy-2-methylisoflavone,7-p-nitrobenzyloxyisoflavone,7-p-nitrobenzyloxy-2-methylisoflavone,7-p-chlorobenzyloxyisoflavone,7-cetyloxy-2-methylisoflavone,7-(2-octyloxy)-isoflavone,7-benzyloxy-3',4'-dimethoxyisoflavone, and7-hexadecyloxyisoflavoneAs a weight-gain promoting anabolic ingredient.

Abstract: Nonestrogenic 5-methyl-alkoxy-isoflavone, namely, 5-methyl-7-methoxy-isoflavone, 5-methyl-7-ethoxy-isoflavone, 5-methyl-7-isopropoxy-isoflavone, and 5-methyl-7-(2-hydroxy-ethoxy)-isoflavone are useful as weight-gain promoters in feeds from which the 7-methoxy and 7-ethoxy isoflavones have been excluded because of estrogenic effects. They are more effective than 7-isopropoxy-isoflavone as well.

Abstract: Compounds of the formula (1), or their salts, ##STR1## are prepared as follows: (A) A COMPOUND OF THE FORMULA (II) ##STR2## is reduced; or (B) A COMPOUND OF THE FORMULA (III) ##STR3## is reacted, e.g. after protecting the phenolic hydroxy group attached to position 3 of the ring, with a compound of the formula (IV), ##STR4## or (C) GROUP R.sup.1 of a compound of the formula (V) ##STR5## is removed in an acidic medium, AND, IF DESIRED, THE COMPOUND OF THE FORMULA (I) is converted into salt, or a salt of a compound of the formula (I) is converted into the free acid or another salt thereof.The compounds of the formula (I) and their salts are valuable artificial sweetening agents.In the above formulae"alkyl" is a C.sub.1-4 alkyl group,R is hydrogen or a protecting group capable of splitting off upon hydrogenolysis, preferably benzyl or benzyloxycarbonyl,M+ is a proton or another cation,X is a group of the general formula O.sup.- M.sup.+,Y is halogen, orX and Y together represent an oxygen atom, andR.sup.

Abstract: A sweetening agent in the form of a 1,3-diphenyl-propanone-1 derivative of the formula ##SPC1##Wherein R is hydrogen, hydroxyl, alkoxy or carboxyl-substituted, sulphonyl-substituted, phosphonyl-substituted, dialkylamino-substituted, trialkyl ammonium-substituted alkoxy; R.sup.1 is hydrogen or a hydrophylic group but both R and R.sup.1 are not both hydrogen; R.sup.2 and R.sup.3 are hydroxyl or alkoxy.

Abstract: A method of anabolic treatment in humans comprises administering a compound of the following formula: ##SPC1##Wherein R is halosubstituted, nitrosubstituted, or unsubstituted benzyl, R.sup.2 is hydrogen, methyl or carboxy, and R.sup.3 and R.sup.4 are hydrogen, methoxy or nitro. Pharmaceutical compositions are also disclosed.
