The compound pentachloropyrimido a naphthyridin one was

In addition, naphthyridines containing the PF-477736 moiety, such as pyrimido[2,1-f][1,6]naphthyridines, have shown tracheal muscle relaxation activity Our efforts in studying mitochondria type of structure was firstly focused on their antiparasitic properties such as antileishmanial activity and trypanosomiase diseases [3] and now on their spectroscopy properties.
Experimental
The investigation by FT-Raman and FTIR-ATR spectroscopy was performed on a crystalline sample obtained by preparation of halonaphthyridines whose crystal structure was determined and reported elsewhere [12].
