Tracing the start of COVID-19 in GA

At a time when COVID-19 appears to be receding in much of Georgia, it’s worth revisiting the start of the pandemic in early 2020. Emory virologist Anne Piantadosi and colleagues have a paper in Viral Evolution on the earliest SARS-CoV-2 genetic sequences detected in Georgia. Analyzing relationships between those virus sequences and samples from other states and countries can give us an idea about where the first COVID-19 infections in Georgia came from. We can draw Read more

Reddit as window into opioid withdrawal strategies

Drug abuse researchers are using the social media site Reddit as a window into the experiences of people living with opioid addiction. Abeed Sarker in Emory's Department of Biomedical Informatics has a paper in Clinical Toxicology focusing on the phenomenon of “precipitated withdrawal,” in collaboration with emergency medicine specialists from Penn, Rutgers and Mt Sinai. Precipitated withdrawal is a more intense form of withdrawal that can occur when someone who was using opioids starts medication-assisted treatment Read more

CROI: HIV cure report and ongoing research

The big news out of CROI (Conference on Retroviruses and Opportunistic Infections) was a report of a third person being cured of HIV infection, this time using umbilical cord blood for a hematopoetic stem cell transplant. Emory’s Carlos del Rio gave a nice overview of the achievement for NPR this morning. As del Rio explains, the field of HIV cure research took off over the last decade after Timothy Brown, known as “the Berlin patient,” Read more

Rules of thumb for drug discovery

People interested in drug discovery may have heard of “Lipinski’s rule of five,” a rough-and-ready set of rules for determining whether a chemical structure is going to be viable as a orally administered drug or not. They basically say that if a compound is too big, too greasy or too complicated, it’s not going to get into the body and make it to the cells you want to affect. These guidelines have been the topic of much debate among medicinal chemists and pharmacologists.

The namesake for this set of rules, Chris Lipinski, will be speaking at Winship Cancer Institute Wednesday afternoon (4:30 pm, Nov 5, C5012) on “The Rule of 5, Public Chemistry-Biology Databases and Their Impact on Chemical Biology and Drug Discovery.” Lipinski spent most of his career at Pfizer (while there, he published the “rule of 5 paper“) and now is a consultant at Melior Discovery.
