| Abstract: | Calculations of the charge of the pyrrolic nitrogen atom in the trail pheromone ofAtta texana, methyl 4-methylpyrrole-2-carboxylate, as well as 17 analogs, showed that the most active compounds all had the same charge of –0.51 electrons on the nitrogen atom. It is suggested that the close value for this charge may be important in recognition by the receptor.This work was supported in part by the University of Iowa Computer Center. |
