Abstract Some functional derivatives of blepharismone, the low-molecular conjugation hormone of Blepharisma japonicum, were synthesised and tested for their biological activity. The lipophilicity constant of the substituent in 5-position of the aromatic system directly correlates with the conjugation-inducing effect of this substance. Any change in the N-formyl-position leads to compounds less active than blepharismone, non-active or even inhibitory. Blepharismone-related kynurenine derivatives are inhibitors of the gamone activity depending on structural relationship.

Triethylamine borane, (C2H5)3N.BH3, is a stable, safe and readily available reagent which at 80 °C reduces carboxylic acids to primary alcohols in high yields; functional derivatives of carboxylic acids such as esters, nitriles or amides are virtually nonreactive with this reagent under the same conditions. Aldehydes, ketones and acid chlorides, however, react readily. No solvent is required for the process.
