Physiologically active pterocarpan compounds, methods for the isolation thereof and therapeutically active compositions containing them.

摘要

The invention relates to physiologically active pterocarpan-compounds and methods for the isolation thereof. These compounds have the formula I <CHEM> wherein R<1> represents a hydrogen atom and R<2> represents a -CH2CH2-CH(CH3)-CH2OH group, or R<1> represents a <CHEM> and R<2> 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.
