摘要:
The present invention relates to the pharmaceutics, biotechnological and chemical, and particularly to a process for preparing a composition for detecting and measuring the concentration of endotoxins or lipopolysaccharides, peptidoglycans and (1,3)-β-D-glucans, using an extract from the hemocytes of the lobster as a starting material, the changes to the composition to increase the sensitivity, and processes for measuring endotoxins, peptidoglycans and (1,3)-β-D-glucans using said composition.
摘要:
This invention is related to chemistry and pharmacy and, in particular, to the production of novel molecular entities: esterane derivatives fused with spirostanes rings, acting upon the Central Nervous Systems (CNS). From diosgenin, a naturally occurring sapogenin, with some subsequent transformations thereof, spirosteroid derivatives of the I-IV general formula can be obtained, with a cyclopentaneperhydrophenantrene nucleus fused to a 25R-spirostanes nucleus. Such molecular entities have an anti-inflammatory and anti-glutamatergic actions that can be used to treat inflammatory, cerebrovascular, neurodegenerative, neuropsychiatric, and neurologic diseases.
