17-OXYMACBECIN DERIVATIVES AND THEIR USE IN THE TREATMENT OF CANCER AND/OR B-CELL MALIGNANCIES.

摘要

The present invention relates to 17-oxymacbecin analogues according to the formula (IA) or (IB) below, or a pharmaceutically acceptable salt thereof, wherein: R1 represents H, OH or OCH3; R2 represents H or CH3 R3 represents H or CONH2 R4 and R5 either both represent H or together they represent a bond (i.e. C4 to C5 is a double bond); and R6 represents H or OH; and R7 represents H or CH3. that are useful, e.g. in the treatment of cancer, B-cell malignancies, malaria, fungal infection, diseases of the central nervous system and neurodegenerative diseases, diseases dependent on angiogenesis, autoimmune diseases and/or as a prophylactic pretreatment for cancer. The present invention also provides methods for the production of these compounds and their use in medicine, in particular in the treatment and / or prophylaxis of cancer or B-cell malignancies.

The present invention also provides methods for the production of these compounds and their use in medicine, in particular in the treatment and / or prophylaxis of cancer or B-cell malignancies. The invention is based on a dust suction adapter device comprising a base body unit (12) having a coupling point (14) for attachment to a hand-operated machine tool (16) and having at least one suction channel (18), and further comprising a suction head unit (20) displaceable on the base body unit (12). It is proposed that the dust suction adapter device is provided with at least one interface (22) for an external suction unit (24).
