Their technique effectively counteracted 2 highly addicting drugs– fentanyl and methamphetamine– in laboratory experiments.
Drug overdoses in the United States have actually increased greatly in the last two decades. Nearly 92,000 individuals passed away from overdoses of controlled substances and prescription opioids in 2020– more than 5 times the number of deaths in the year 2000– and synthetic opioids like fentanyl are among the primary offenders.
Naloxone (an injectable medication also marketed as the nasal spray Narcan) has actually conserved numerous lives, but it just works for opioid overdoses and has other limitations. MaxQ (P6AS)– as an antidote for methamphetamine and fentanyl.
MaxQ (P6AS)– as an antidote for methamphetamine and fentanyl. Whether this substance helps promote a drugs excretion from the body must be checked experimentally. Isaacs thinks that the excretion of fentanyl could assist prevent this phenomenon, understood as renarcotization.
Isaacs believes it might even be utilized to deal with overdoses of exceptionally effective drugs like carfentanil, which has been connected to a string of overdose deaths in current years.
MaxQ: A Potent Supramolecular Host for In Vivo Sequestration of Methamphetamine and Fentanyl” by Adam T. Brockett, Weijian Xue, David King, Chun-Lin Deng, Canjia Zhai, Michael Shuster, Shivangi Rastogi, Volker Briken, Matthew R. Roesch and Lyle Isaacs, 15 December 2022, Chem on December 15, 2022.
” Opioids currently have a turnaround agent in naloxone, but there are a range of non-opioid drugs of abuse– like methamphetamine, PCP, mephedrone, euphoria (MDMA) and drug– that do not have a specific antidote,” stated the studys lead author Lyle Isaacs, a professor in the Department of Chemistry and Biochemistry at UMD. “Thats one of the substantial chances for our substance.”

In vitro and in vivo laboratory tests revealed that P6AS effectively sequestered fentanyl and methamphetamine, a non-opioid stimulant, and reduced their potentially lethal biological results. Extra in vitro tests revealed that P6AS likewise binds strongly to other drugs, including Mephedrone, ecstasy, and pcp, which recommends that P6AS might at some point be used to combat a large selection of drugs.
The study was conducted by Isaacs laboratory in cooperation with researchers in UMDs Department of Cell Biology and Molecular Genetics and Department of Psychology. Although the synthesis and chemical homes of P6AS were very first documented in 2020 by Isaacs and Weijian Xue, a previous post-doctoral associate in the Department of Chemistry and Biochemistry, this study reports its first in vivo applications.
P6AS works as a molecular container, which means that it binds and sequesters other compounds in its main cavity.
” When we put molecules into our containers, we can turn off their biological residential or commercial properties and therefore reverse any effects that they may have,” Isaacs explained. “Weve determined the interaction in between our container and a range of drugs of abuse– things like methamphetamine, fentanyl, ecstasy, PCP and others– and we discover that this brand-new container that weve made binds a lot of them really strongly.”
In vivo tests revealed that the effects of methamphetamine could be reversed by administering P6AS 5 minutes later, which is “still a bit brief for real-world scenarios,” Isaacs discussed. The results of fentanyl, however, might be reversed by administering P6AS as much as 15 minutes later, which comes closer to fulfilling the federal guidelines for drug reversal representatives.
Unlike naloxone, which stops a drug of abuse from binding to receptors in the brain, the UMD teams molecular container targets drugs straight in the blood stream.
” Our substance takes in the drug in the blood stream and, we think, helps promote its excretion in the urine,” Isaacs stated. “This is called a pharmacokinetic process, where were trying to reduce the concentration of free drug thats present in the body.”
Whether this compound helps promote a drugs excretion from the body need to be evaluated experimentally. Isaacs thinks that the excretion of fentanyl might help avoid this phenomenon, understood as renarcotization.
Isaacs said it will likely be years before the brand-new compound is approved for human use. He imagines that it could be provided as an injection, much like naloxone but potentially with more comprehensive applications. Isaacs believes it could even be utilized to deal with overdoses of extremely powerful drugs like carfentanil, which has been linked to a string of overdose deaths in the last few years.
” There are other synthetic opioids that are much stronger than fentanyl– things like carfentanil, which are challenging to reverse using naloxone,” Isaacs stated. “In addition, individuals are getting so much fentanyl that multiple dosages of naloxone are needed, so theres room for a improved and brand-new agent that might assist in those scenarios.”
