Seeking international collaboration. Project: Structural determination and 
functional study of a peptide-a potential medicine for clinical therapeutic 
treatment of Erectile dysfunction.
 
About the details of the peptide, please see ‘Toxin Tx2-6 from the spider 
"Phoneutria nigriventer" improves the impaired erectile function in DOCA-Salt 
hypertensive rats’(The FASEB Journal. 2007;21:750.32). The combination 
treatment of the peptide with Sildenafil to those patients who are insensitive 
to Sildenafil single can considerably prove their condition.  
 
We constructed several of its expression clones in Bacterial and yeast , and we 
have done some experiments in animals with the products , generally the results 
are satisfying.
