Sat down with former NIH director Monica Bertagnolli yesterday at #aaasmtg to talk about layoffs set to hit the NIH and other agencies “We’re going to lose the next generation, that is the most difficult loss," she said, adding she got very little sleep Friday 🧪 www.statnews.com/2025/02/16/n...

Trump administration layoffs set to hit NIH are ‘devastating,’ former director Monica Bertagnolli says

Sweeping layoffs are set to hit federal health and science agencies, including at the NIH, and former director Monica Bertagnolli called the situation at the NIH “devastating.”

There have been both program officers and scientific review officers who have been terminated. However, I do not have a good sense of the numbers nor the rationale for one over others. 3/n

The biggest hit to extramural program staff appears to be grants management specialists (GMSs). It appears that 15-20% of GMSs were terminated. This is quite concerning since these folks have already missed essentially a month of getting-grants-out time and have lots to do. They already work hard.

Congratulations to Sophie Padilla on the publication of "Vancomycin–Teixobactin Conjugates" in the Journal of the American Chemical Society pubs.acs.org/doi/10.1021/.... Conjugation of vancomycin to a fragment of teixobactin enhances antibiotic activity by 4–8-fold and restores activity against VRE.

Vancomycin–Teixobactin Conjugates

Vancomycin continues to be a widely used antibiotic of last resort in treating drug-resistant pathogens despite the emergence of vancomycin-resistant strains such as vancomycin-resistant Enterococci (VRE). This communication reports that conjugation of vancomycin to a second antibiotic that targets a different region of lipid II enhances and rescues its antibiotic activity. Conjugation of vancomycin to a minimal teixobactin pharmacophore in which residues 1–6 are replaced with an aromatic amide results in substantial enhancement in activity over the individual components or mixtures thereof. Three conjugates with minimum inhibitory concentrations (MICs) of 0.5 μg/mL against methicillin-resistant Staphylococcus aureus (MRSA) and 0.063–0.125 μg/mL against methicillin-susceptible Staphylococcus aureus (MSSA) were identified. Each of these conjugates is also active against VRE, even though the individual components are inactive, with the most active conjugate (Cbp-Lys10-teixo7–11-vanco) having an MIC of 2–4 μg/mL. These findings demonstrate that conjugation of vancomycin to a minimal teixobactin pharmacophore is an effective strategy for enhancing the activity of vancomycin against important Gram-positive pathogens.

Wishing all of my first-year graduate students success in their day-long Organic Spectroscopy final exam. For previous years' course materials, see: canvas.eee.uci.edu/courses/57646 (2023 website), www.youtube.com/playlist?lis... (2020 lecture videos), www.chem.uci.edu/~jsnowick/or... (old exams).

I am always delighted to see what my graduate students can achieve when entrusted to do so. Two of my graduate students submitted their manuscripts to our favorite journal today. It's been great working with each of them and watching them take ownership of their work and manuscripts in the writing.

Reasons to Give Thanks: Exciting new results Manuscripts almost ready to go out Encouraging score on grant proposal Superb coworkers Great colleagues and friends Supportive department Engaged grad students in Org. Spec. class Fun travel as part of my career My health My loving supportive husband

Just starting preparation for the Nowick group pre-Thanksgiving dinner. I've just pulled two loaves of my sourdough wheat bread out of the oven. John has already made his all-butter pie crusts and is beginning to work on the apple and pumpkin pies and the cranberry sauce and cranberry-orange relish.
