A combined team of researchers from the Shanghai Institute of Biochemistry and Cell Biology and ShanghaiTech University’s, iHuman Institute has created non-hallucinogenic analogs of LSD and psilocybin for possible treatment of mental illnesses. In their paper published in the journal Science, the group describe the analogs they created and how they performed in mice.
In recent years, scientists have found that some hallucinogens, such as LSD and psilocybin, can provide relief for patients suffering from chronic depression and other mental illnesses like PTSD. And while many patients may enjoy the hallucinogenic experience, many do not. Scientists have therefore been taking a closer look at hallucinogens to find the mechanisms that provide relief to those suffering from depression—and if possible, to determine if the hallucinogenic effects of such drugs are necessary for treatment.
In this new effort, the researchers took a close look at both LSD and psilocybin using X-ray crystallography, and were able to determine their conformations when they become bound to the neural receptor 5-HT2AR. They found that both molecules could bind to 5-HT2AR in two ways, resulting in unique conformations. They then created compounds that would bind to 5-HT2AR in the secondary type of binding they discovered.
