Dr. Hyan-Ju Park, Professor at the School of Pharmacy of Sungkyunkwan University, in South Korea, spent some months with us sharing her expertise in medicinal chemistry, which was very valuable to our group of bioassays in parasites of tropical diseases and cancer. Some of the best molecules that we have published together with our collaborators were analyzed with her and new ideas for progressing analogs of those natural products were discussed. This is headed to be an important Panama-South Korea collaboration in the area of drug discovery. This exchange from visiting Prof. Park adds to the similar ongoing work established some years ago between our group and the Ocean University of Qindao, China.
