摘要:
Biologically active WS 6049 substances obtainable by culturing a strain belonging to the genus Actinomadura in an aqueous nutrient medium under aerobic conditions and recovering WS 6049-A substance and/or WS 6049-B substance. The invention also relates to a process for preparing the new substances and pharmaceutical compositions comprising such substances as an active ingredient together with a non-toxic, pharmaceutically acceptable carrier.
摘要:
This application relates to new compounds called WS-9326A, WS-9326B, and their derivatives having valuable pharmaceutical properties and which are obtainable by culturing a WS-9326A and/or WS-9326B producing strain belonging to the genus Streptomyces in nutrient medium and recovering such compounds or salts thereof from the resultant cultured broth. The invention also relates to a process for the production of such compounds and to pharmaceutical compositions containing them or a pharmaceutically acceptable salt thereof as an active ingredient. The invention furthermore relates to a biologically pure culture of the microorgnism Streptomyces violaceoniger No. 9326 (FERM BP-1667). Figure 1 Spectrum of Infrared Absorption of WS-9326A in KBr
摘要:
@ New biologically active substances - called WS 7739 - having pharmacological activity are prepared by fermentation of a strain belonging to the genus Streptomyces, e.g. Streptomyces phaeofaciens subsp. matsuenensis no. 7739 FERM BP 660 in a nutrient medium containing sources of assimilable carbon and nitrogen under aerobic conditions; pharmaceutical compositions containing these substances as active ingredients are effective in treating deseases, such as asthma, thrombosis etc.
