Araliphatylaminoalkanediphosphonic acids of formula ##STR1## wherein R.sub.1 is an aromatically substituted aliphatic radical, R.sub.2 is hydrogen or a monovalent aliphatic radical and alk is a divalent aliphatic radical, and their salts, exhibit a pronounced regulatory action on the calcium metabolism and can be used as medicaments for the treatment of diseases that are attributable to calcium metabolism disorders. They are prepared, for example, by reacting a compound of formula ##STR2## where...

The invention relates to novel aromatic acids, especially to compounds of formula ##STR1## wherein R.sub.1 is lower alkyl, R.sub.2 is lower alkyl, R.sub.3 is hydrogen, carboxy or sulfo, R.sub.4 is carboxy or sulfo, G is an unsubstituted or substituted 1,4-phenylene group or an unsubstituted or substituted 1,4-naphthylene group, and wherein either R.sub.5 and R.sub.6 together are an additional bond and L is an oxygen or sulfur atom or wherein R.sub.5 is hydrogen, R.sub.6 is halomethyl and L is an...

The incorporation of many percarboxylic acids in household formulations is precluded from by adverse physicochemical properties, such as a propensity to decompose too quickly during storage or explode on impact or when subjected to pressure, though otherwise they would be effective disinfectants and bleaching agents, especially at hand-hot temperatures. The invention provides a stable and effective selection of organic percarboxylic acids which satisfy one or other of the general formulae (1) or...

Novel quinolonecarboxylic acids of the formula: ##STR1## wherein R.sup.1 is C.sub.1 -C.sub.4 alkyl, R.sup.2 and R.sup.3 each is identically or differently hydrogen or C.sub.1 -C.sub.4 alkyl, R.sup.4 is cyclopropyl, phenyl, halo-phenyl, or thienyl optionally substituted by C.sub.1 -C.sub.4 alkyl or halogen, and R.sup.5 is halogen, or pharmaceutically acceptable salts thereof having a more potent and longer lasting antibacterial activities against G(+) and G(-) bacteria than known analogues, usefu...

The invention relates to novel aromatic acids, especially to compounds of formula ##STR1## wherein R.sub.1 is lower alkyl, R.sub.2 is lower alkyl, R.sub.3 is hydrogen, carboxy or sulfo, R.sub.4 is carboxy or sulfo, G is an unsubstituted or substituted 1,4-phenylene group or an unsubstituted or substituted 1,4-naphthylene group, and wherein either R.sub.5 and R.sub.6 together are an additional bond and L is an oxygen or sulfur atom or wherein R.sub.5 is hydrogen, R.sub.6 is halomethyl and L is an...

The invention concerns novel 1,3-dioxane alkenoic acid derivatives of the formula I ##STR1## wherein: n is the integer 1 or 2; Y is methyleneoxy, vinylene or ethylene; A.sup.1 is (1-6C)alkylene; R.sup.1 is a group of the formula R.sup.2.A.sup.2 -, in which: R.sup.2 is phenyl unsubstituted or bearing up to three substituents which are independently selected from (1-6C)alkyl, (1-6C)alkoxy, (2-6C)alkanoyl, (1-6C)alkylthio, (1-6C)alkylsulphonyl, halogeno, trifluoromethyl, nitro and cyano; A.sup.2 is...

An aromatic peroxyacid which satisfies the general formula (1): in which X represents hydrogen or a compatible substituent, R represents --(CH2).sub.n -- in which n=2 or 3, and Y and Z each represent independently a substituent selected from hydrogen or an alkyl or aryl group or an aryl group substituted by a compatible substituent or alkaryl group provided that at least one of Y and Z is not hydrogen if n=3. The peroxyacid is an effective bleaching and disinfecting agent which has a long shelf ...

Phenoxycarboxylic acids of the formula ##STR1## wherein R, R.sub.1, R.sub.2, R.sub.3, R.sub.4 R.sub.5, Z and n are as hereinafter set forth, are as described. The compounds of formula I are antagonists of slow reacting substance of anaphylaxis (SRS-A), which renders them useful as agents for the treatment of allergic conditions.

A series of alkanoarachidonic acids have been prepared as modulators of the arachidonic acid cascade to increase the production of biologically desirable compounds and minimize the production of biologically undesirable compounds. Examples of desirable compounds in this respect comprise postaglandins and thromboxanes whereas undesirable compounds comprise the mono- and polyhydroxyarachidonic acids and leukotrienes. The alkanoarachidonic acids and their intermediates are of the general formula: #...
