About

Providing straightforward information pertaining to drugs, drug use & drug policy. The Grey Pages promotes drug-related literacy and advocates a system of viable and tolerant drug policies. This is my personal collection of commentaries, essays, tid-bits, and other such writings on everything ranging from drug use, drug policy and drug-myths, to drug-science, addiction, human behavior, and the workings of the human brain. I started this blog with a particular focus on opioids, and over the past year have found my interest gravitate toward the intriguing, ever-changing world of designer intoxicants (i.e. "research chemicals" or "designer drugs").

More SAR


All of the structures included will give a perfect structural overlay - right click @ 'save' image to open in Microsoft Paint. Select image cut & paste mode. Find the 'Selection' box with the arrow underneath (in the upper left corner) - scroll to the bottom of the menu and select "trasparent selection". This allows you to cut and drag one image over the other with a transparent background.




This image demonstrates the similarity between narcotics in their configuration to the Mu receptor. 

This image depicts the morphine backbone along with several opioids in a matching configuration, with the backbone in red. Note the similarities in each molecule. Also note the T-shape of their structures (th morphine-derivatives in particular). The structural characteristics of the more potent opioids emphasize the morphine rule, with enhancements or modifications in the areas most significant to receptor docking & recognition.
