PROCESS FOR THE PRODUCTION OF ANTITUMOUR PHARMACEUTICAL COMPOSITIONS USING PUSH-PULL BUTADIENES, COMPOUNDS AND USES THEREOF
The present invention reports the obtaining of carbonyl compounds and derivatives, through syntheses with high yield and purity, providing anti-humoral active principles with selective antiproliferative properties and anti-metastatic activity.
The present invention refers to the development of new polyfunctional push-pull butadienes and their O and C-prenylated, benzoylated and iodide derivatives, with high electronic conjugation in the lateral chain. These compounds exhibit high anti-tumor selectivity, causing cell death by apoptosis, also show anti-metastatic and non-mutagenic properties in the experimental studies performed.

METHOD AND PROCESS PLANT FOR TREATMENT OF A STREAM OF MIXED COMPOUNDS
The invention concerns a method for treatment of a stream of mixed compounds (4a) obtained from a process (3) comprising decomposition and/or conversion of a wood or pulp material, the method comprising: feeding the stream (4a-4e) through a processing arrangement (2) comprising one or more treatment units (10, 20, 30, 40, 50) arranged to separate at least a first compound from other compounds in the stream and form a first product flow (4f) containing the first compound, wherein the one or more treatment units comprises at least a first primary separation unit (20) arranged to separate one or more compounds other than the first compound from the stream; and feeding the compounds separated from the first compound in the first primary separation unit (20) to a first auxiliary separation unit (21) so as to separate a second compound from at least one of the other compounds separated from the first compound in the first primary separation unit (20) and thereby increase the purity of said second compound and form a second product flow (22, 23) in the form of a purified second compound and/or a purified derivative of the second compound, wherein the second compound is dimethyl sulfide (DMS, CH3—S—CH3), methyl mercaptan (CH3—S—H) or acetone (CH3—CO—CH3).
