Scientists from the Immuno-Pharmacology and Interactomics group at the Luxembourg Institute of Health (LIH), in collaboration with the Center for Drug Discovery at RTI International (RTI), have demonstrated that conolidine, a natural painkiller derived from the pinwheel flower and traditionally used in Chinese medicine, interacts with the newly identified opioid receptor ACKR3/CXCR7 that regulates opioid peptides naturally produced in the brain. The researchers also developed a synthetic analogue of conolidine, RTI-5152-12, which displays an even greater activity on the receptor.
Building on their previous findings, scientists from the Immuno-Pharmacology and Interactomics group at the Department of Infection and Immunity of the Luxembourg Institute of Health (LIH), in collaboration with the Center for Drug Discovery at RTI International (RTI), a nonprofit research institute, have demonstrated that conolidine, a natural painkiller derived from the pinwheel flower and traditionally used in Chinese medicine, interacts with the newly identified opioid receptor ACKR3/CXCR7 that regulates opioid peptides naturally produced in the brain.

Cancer Drug Shows Potential Against Pseudo SARS-CoV-2 in Lab Tests
Despite the effectiveness of COVID-19 vaccines, treatments are still needed to combat this disease, which has killed millions of people and still kills thousands each day across the world. Scientists at the UNC School of Medicine conducted lab experiments showing how the cancer drug lenalidomide disrupts a cellular pathway in human cells so that pseudo-viruses derived from SARS-CoV-2 – the virus that causes COVID-19 – cannot enter cells to cause infection.
The research, published in a letter to the journal Signal Transduction and Targeted Therapy, shows the potential of an existing FDA-approved drug to help doctors treat the sickest COVID-19 patients.
