Speed dating for pharmaceuticals

A simple analysis of hydrogen bond strengths finds the best crystallisation partners for drugs, say UK scientists. 

The properties of active pharmaceuticals can be altered by crystallising them with an inactive partner molecule in a cocrystal. Finding good cocrystal partners experimentally is time consuming, and current computational methods are laborious as they calculate the crystal structure, atom by atom. Cocrystals could provide new ways to deliver drugs and improve their properties, so the search for them is on.  More...
