Message from Chair
Greetings TOXI members! I hope you have had a good start to 2020 and are ready to make summer conference plans! We are pleased to share in this first TOXI newsletter of the year the program for our annual meeting to be held August 16-20 in San Francisco, California.
In addition to the excellent thematic symposia, contributed presentations and social events really make our meeting a wonderful and unique small-meeting-in-a-big-meeting experience. I am always pleased to note that our young investigator sessions are equally well attended by leaders in our field as sessions with invited top speakers, and of course, the TOXI poster and awards session is officially the best event there is at ACS. Students and postdoctoral researchers can apply to give talks, and all are encouraged to submit abstracts for posters or the general oral session. Students and postdoctoral researchers can also obtain financial support from TOXI to participate in the meeting. Please read further about the 2020 National Meeting Program, Call for Abstracts and Travel Grants
The scientific and professional opportunities supported by TOXI are organized by the volunteer efforts of the elected officers of the division and committees supporting them. We are pleased to announce the results of the recent elections and introduce new TOXI officers. Please join me in congratulating the winners and thanking them for being ready to give back to the division! New TOXI Officers
Last but not least, please recognize fellow scientists who have made major contributions in Chemical Toxicology with nominations as ACS fellows or as candidates for the TOXI Founders’ Award: TOXI call for Award Nominations
In closing, a big shout out to our TOXI Program Chair Prof. Penny Beuning, Program Chair Select Prof. Michael Trakselis and the Members of the Program and Program Development Committees for their great efforts in planning the meeting. Thank you to our Awards Committee Chair, Prof. Kent Gates, and to our Communications Chair, Prof. Thomas Spratt for this newsletter. Finally, please share this newsletter with others: encourage co-workers to become TOXI members and join our annual meeting this summer. Looking forward to seeing many familiar faces and welcoming as many first-time ACS-TOXI attendees as possible!
TOXI National ACS meeting program
Abstract submission is open for the Fall ACS National Meeting, August 16-20, 2020, in San Francisco.
TOXI programming will be held Sunday-Wednesday. Symposium sessions are:
Chemical Exposures and Impact on Health. Organizer: Rob Turesky, University of Minnesota, and Sarah Shuck, City of Hope
Chemical exposures linked to neurotoxicity and cognitive function is an area of ever-increasing importance to public health. The risk assessment of health hazards requires knowledge about environmental and chemical exposures, followed by mechanistic studies to understand toxicity, which can be linked to epidemiology observations and biomarkers on health effects in human cohorts. In this symposium, state-of-the-art mass spectrometry technologies are presented to identify exposures to a wide range of toxicants in the environment, followed by mechanistic studies on chemicals that impact cognitive function/neurotoxicity, and findings in human cohorts.
Genome-wide Perspectives on the Formation, Repair, and Consequences of DNA Damage. Organizers: Sabrina Huber, ETH Zürich, and Maureen McKeague, McGill
Toxicant-induced, covalent modification of DNA, resulting in the formation of DNA adducts, is one of the earliest events in chemical carcinogenesis. If not repaired, these modifications can lead to mutations, which can alter gene expression and disrupt normal cell function. Thus, the study of DNA adduct formation, abundance, and mutagenic consequences is of fundamental importance to better understand the biological consequences of exposures and their associated mechanisms of toxicity as a basis for promoting prevention strategies in environmental health. This session will provide an overview of mutation signatures in toxicology, illustrate chemical approaches to shed light on mechanisms of DNA damage, repair, and maintenance in normal physiology and disease.
Metabolism of Fluorinated Compounds and Safety Relevance
Organizers: Nicholas Meanwell, Bristol-Myers Squibb, and Fred Guengerich, Vanderbilt University
Fluorine is widely used in medicinal chemistry and of the 38 small molecule drugs that were approved by the FDA in 2018, 18 contain fluorine. In the presence of a nucleophile or drug-metabolizing enzymes, the release of fluoride can be facile and for a drug suffering from significant C−F bond cleavage, fluoride’s strong affinity for bones may lead to safety issues such as skeletal fluorosis. Considering the reactivity of some fluorinated drugs and their metabolites, they may alkylate biological targets and lead to toxicity, especially if the fluorine is positioned close to a cysteine thiol when the drug molecule is bound to an off-target protein. Cytochrome P450-mediated hydroxylation at fluorinated aliphatic carbons can also release fluoride and produce toxic metabolites.
Toxicology of Antibody-Drug Conjugates. Organizers: Natalia Tretyakova, University of Minnesota, and Michael Trakselis, Baylor University
Antibody-drug conjugates (ADC) represent an exciting new area of anticancer drug discovery. This approach allows for targeted drug delivery to the tumor with increased accuracy and reduced side effects. However, studies in laboratory animals and clinical trials revealed unexpected dose limiting toxicity for many ADCs, which is not completely understood. This session will focus on the design, clinical effects, and mechanisms of toxicity ADCs. ADC drugs currently in clinical trials, novel approaches, and challenges with ADC safety will be discussed.
Keynote address,
The Keynote address will be presented by Cynthia Burrows. Dr Burrows is Distinguished Professor and Thatcher Presidential Endowed Chair of Biological Chemistry at the University of Utah. She has performed outstanding research in mechanisms of DNA damage formation and repair.
