Findings on Terpenes Detailed by Investigators at University of Lille

May 27, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Terpenes have been published. According to news originating from Lille, France, by NewsRx correspondents, research stated, "Three selective CB2 cannabinoid receptor ligands have recently been discovered to be promising anti-inflammatory agents but their low water solubility hinder their per os administration. The popularity of the cyclodextrins, from a pharmaceutical standpoint lies on their ability to interact with poorly water-soluble drugs and improve their solubility."

Our news journalists obtained a quote from the research from the University of Lille, "Herein, three experimental approaches for calculating the stability constant of complexes between the selective CB2 ligands and either the beta-CD or the HP-beta-CD, were tested: nuclear magnetic resonance, micellar electrokinetic chromatography and high performance liquid chromatography in reversed phase. In NMR studies the calculated K values were relatively high and were between 1486 and 3571 M-1 with beta-CD. With HP-beta-CD they were between 1203 and 2650 M-1. Concerning the two others techniques the K values were found lower. In MECK studies with beta-CD they were between 308 and 792 M-1 and with HP-beta-CD between 124 and 764 M-1. Finally in RP-HPLC studies with beta-CD, they were between 539 and 1144 M-1 and with HP-beta-CD between 196 and 396 M-1. These calculated constants suggest that a complexation phenomenon occurs."

According to the news editors, the research concluded: "A model for inclusion of one of the CB2 ligands in the beta-CD was then proposed from molecular modeling studies."
