fysiologiskt aktiva pterokarpanfoereningar, foerfaranden foer deras isolering och (innehaollanterapeutiskt aktiva blandningar

摘要

The invention relates to physiologically active pterocarpan-compounds and methods for the isolation thereof. These compounds have the formula I CHEM wherein R1 represents a hydrogen atom and R2 represents a -CH2CH2-CH(CH3)-CH2OH group, or R1 represents a CHEM and R2 represents a hydrogen atom, together with all optical isomers and racemic mixtures thereof. These compounds are effective against the toxic venoms of poisonous snakes, spiders and other insects, and against E. coli endotoxins. The invention further relates to therapeutically active compositions containing the above pterocarpan compounds.
