摘要:
A process for the production of (optionally lipid containing) eicosapentaenoic acid comprises the steps of a) culturing a microorganism capable of producing lipid containing eicosapentaenoic acid belonging to the genus Pseudomonas, Alteromonas and Shewanella, to produce lipid containing eicosapentaenoic acid, and b) recovering the (optionally lipid containing) eicosapentaenoic acid from the cultured product. Microorganisms capable of producing eicosapentaenoic acid belonging to the genera Pseudomonas, Alteromonas and Shewanella are also disclosed.
摘要:
Nerve growth factor production accelerating agents containing oxazopyrroloquinolines, pyrroquinolinequinones and/or their esters as active ingredient are provided. As the oxazopyrroloquinolines and their esters exhibit such production accelerating activity, they are suitably utilized for preventing and treating functional disorders of central nervous system, particularly, Alzheimer's dementia, cerebral ischemia and spinal trauma, as well as for functional disorders of peripheral nervous system, particularly, peripheral nervous system trauma and diabetic neurosis. As the pyrroquinolinequinones and their esters exhibit strong nerve growth factor production accelerating activity, they are suitably utilized for preventing and treating functional disorders of peripheral nervous system, particularly, peripheral nervous system trauma, diabetic neurosis, etc.

摘要:
[Object] A fatty acid-related polyunsaturated compound can be selectively purified using an industrially operable successive method under moderate conditions. [Content] A highly purified fatty acid-related polyunsaturated compound is obtained by a process comprising steps of forming a complex with silver on account of the high degree of unsaturation of the fatty acid-related polyunsaturated compound, isolating the complex from other fats on account of the hydrophilicity of the complex and then applying dissociating procedures to the complex to obtain the fatty acid-related polyunsaturated compound as a target substance on account of the hydrophobicity of the fatty acid-related polyunsaturated compound. As to the procedures for dissociation, addition of a dissociating agent and reduction of silver are disclosed. As to the dissociating agent, various compounds which produce insoluble composition with silver other than water are disclosed. Furthermore, an apparatus appropriately used to carry out this method is also disclosed.
摘要:
There are disclosed a compound having the following formula: in which R' denotes an aromatic group; Z represents a group (wherein R' denotes hydrogen, a salt forming cation or a protective group for carboxylic acid, and R' denotes hydrogen or a residue of a nucleophilic compound); and X' and X 2 each represent hydrogen or a halogen atom, provided that both X' and X 2 cannot represent hydrogen at the same time; processes for preparing the same; and an intermediate compound useful for preparing the same. The above mentioned compound has a broad antibacterial spectrum and shows strong antibacterial activities against not only gram-positive bacteria but also the gram-negative bacteria, particularly the resistive gram-negative bacteria.

摘要:
Aromatically substituted acetic acids are prepared by the reaction of an aromatically substituted aldehyde with a combination of a trihalomethane and an alkanethiol, and by the reaction of an alcohol derivative (2,2,2-trihalo-1-arylethanol) with an alkanethiol, in the presence of a base in a mixed medium of water and an aprotic polar solvent.
