 Title    Blepharisma japonicum Synthesis of Blepharismone, the Low-Molecular Conjugation Hormone of Blepharisma japonicum  
 Abstract    An effective and versatile synthesis of 5-hydroxytrypto-phane derivatives offers good access to the conjugation in­ ducing hormone blepharismone o f the ciliate Blepharisma japonicum and to derivatives and analogues of this biolog­ ically active compound. 5'-Fluoroblepharismone and 2'-des-formamidoblepharismone induce conjugation at 500 and 1200 times, respectively, the concentration of the true effector. At high concentration, however, the 2'-des-form-amido derivative desensitizes the receptor system for the natural gamone.

 Title    von Blepharisma japonicum Structure-Activity-Relation of Analogues and Homologues of Blepharismone, the Low-M olecular Conjugation Hormone of Blepharisma japonicum  
 Abstract    Some functional derivatives o f blepharismone, the low-m olecular conjugation hormone o f Blepharisma japonicum, were synthesised and tested for their biological activity. The lipophilicity constant o f the substituent in 5-position o f the aromatic system directly correlates with the conjugation-inducing effect o f this substance. Any change in the N -form yl-position leads to com pounds less active than blepharismone, non-active or even inhibitory. Blepharismone-related kynurenine derivatives are inhibitors o f the gamone activity depending on structural relationship.
