Abstract: A novel theophylline-7- acetic acid ester is described. Said ester is obtained by reacting, at a temperature from 1.degree. to 20.degree. C., theophylline-7-acetic acid chloride with d,l-trans-sobrerol.There are further described pharmaceutical compositions with mucosecretolytic-fluidizing and antibronchospastic activity containing the novel ester.

Abstract: A novel derivative of (-)-6,6-dimethylbicyclo [3.1.1]ept-2-ene-2-ethanol (J. P. Bain, J. Am. Chem. Soc. 1946, vol. 68, page 638) is disclosed. The parent composition is marketed e.g. under the name nopol, v. The Aldrich-Europe Catalog Handbook of Fine Chemicals, item 3160-5 nopol 98% 128-50-7.The object of the present invention is the compound of formula (I): 4-(2-hydroxyethyl) -.alpha..alpha.dimethyl-5-hydroxy-3-cyclohexene-1-methanol, with the process for obtaining the same, which consists of the preparation of (-)-(6,6-dimethylbicyclo[3.1.1]ept-2-ene-2-ethanol epoxide, followed by hydration of the above compound. Finally, this invention comprises the pharmaceutical compositions containing the compound of formula (I) which have a mucosecretolytic pharmacological activity.

Abstract: A novel salicylic acid ester is described, which may be combined with inorganic or organic bases to give pharmaceutically acceptable salts. Such an ester is obtained by reaction of (-) campholenic acid chloride, as prepared by a well known technique, with salicylic acid.There are, further, described pharmaceutical compositions having mucosecretolytic, anti-inflammatory, analgesic, antipyretic activity, which contain the novel ester or the salts thereof.

Abstract: There is described a novel acylamide derivative of p-aminophenol as obtained by condensation of 5-(3-carboxy-1-oxo-propoxy)-.alpha.,.alpha.-4, trimethyl-3-cyclohexene-1-methanol acid with p-aminophenol.There are also described pharmaceutical compositions containing the novel p-aminophenol derivative with mucosecretolytic-fluidizing and antipyretic activity.

Abstract: The present invention concerns the new erythromycin salt of the o-carbonyl(1-thiazolidinyl)-benzoic acid having the formula ##STR1## wherein X represents the monovalent cation of erythromycin. The new salt constitutes a novel antibiotic complex for the selective therapy of the respiratory tract.

Abstract: The invention relates to complex salts of N-cyclohexyl-piperazino-acetamides or propionamides with dihydroxy aluminum-.alpha.-hydroxy-carboxylates, a process for preparing them and the use thereof as antiulcer-antisecretive-buffering drugs.

Abstract: Thiazolidine derivatives of formula ##STR1## in which R, R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 have the meanings as defined in the specification, Q is CH or N and X is H or a pharmacologically acceptable cation derived from an inorganic or organic base limited to amino acids. These derivatives are obtained by condensing phthalic or quinolinic anhydride, possibly substituted in the ring, with the thiazolidine, optionally substituted, in an aprotic solvent. Said derivatives as well as the salts thereof possess a fluidizing mucosecretolytic action.
