Research on Biochemical and Physiological Aspects of Pheromone Perception and Chemical Communication in Mammals


– developing the means of profiling volatile constituents of the chemosignal source (headspace extraction, solvent extraction, supercritical fluid extraction, etc., followed by a quantitative chromatographic analysis

– comparing quantitatively the substance profiles under different endocrinological situations

– spectroscopic identification of the pheromonal candidates

– organic synthesis

– testing synthetic analogs biologically alongside with the natural stimulus

The MUP-I (major-urinary protein-I) structure. (A) A topology diagram illustrates the main chain hydrogen bond pattern (dashed lines) between ß-strands in the MUP-I ß-barrel. (B) A ribbon diagram illustrates the position of HMH within the MUP-I pheromone binding site and highlights the proximity of pheromone to the point of separation between ßd and ßc. ( C ) A ribbon diagram illustrates HMH binding viewed from the entrance to the ß-barrel.
