    SE5:E3: A Process Chemist's Romance with Scaling a Macrocyclic Peptide

    Last episode, we watched medicinal chemistry dream up enclitide (MK-0616) — this week we find out what happens when someone actually has to make it. Dani and LC are joined by David Thaisrivongs and Gao Shang to unpack their recent JACS paper on the total synthesis of enlicitide, a macrocyclic peptide complex enough to keep company with taxol, vancomycin, and eribulin. Along the way they get into the pivot from solid-phase to solution-phase peptide synthesis, the perpetual headache of sourcing non-canonical amino acids and how biocatalysis cracked it open, and the crystallization detective work that let the team ditch chromatography entirely. There's also a great discussion on why a late-stage macrolactamization became a late-stage RCM — the kind of route decision that looks obvious only in hindsight. Fair warning: this one was among JACS's top-accessed papers of 2025, so you're in good company! If you enjoyed this chapter of the enlicitide story, stay tuned—we've got plenty more peptide chemistry, process development adventures, and behind-the-scenes drug discovery stories coming your way this season.

    SE5:E2: The Macrocyclic Mullet

    What happens when the textbook SAR playbook stops working? On this episode of Pharm to Table, Rob Garbaccio joins Dani and LC to share the discovery story behind enlicitide (MK-0616), a journey filled with unusual SAR, creative problem-solving, and plenty of chemistry twists along the way. From issue-driven drug design to non-canonical amino acids and modular synthesis strategies, this conversation offers a behind-the-scenes look at how real medicines are discovered. If you're training as a chemist today, this is a story you won't want to miss.

    SE5:E1 - A Journey of Synthetic Chemistry Innovations at Merck

    To kick off Season 5, Dani and LC discuss a recent perspective published in the Journal of Organic Chemistry that highlights innovations in synthetic chemistry which trace their origins to the work of discovering, developing and commercializing novel therapeutics. This publication was the most accessed paper published in JOC in 2025! Dani and LC explore the motivations on writing it, its main thesis and lesson learned from reexamining nearly 75 years of chemistry innovations at Merck. Be sure to listen through to the very end for a special Season 5 theme reveal!

    SE4:E8: From Discovery to Process, Part 2: Getting Ugi with it - scaling a 3CL protease inhibitor

    In Part 2 of our Pharm to Table deep dive on MK‑7845, Dani and LC shift from invention to implementation, welcoming process chemists Nastaran Salehi Marzijarani and Ben Turnbull to the pod. We explore how the team re‑imagined the synthesis to enable robust, scalable supply—and why a classic multicomponent reaction you probably remember from school, the Joullié–Ugi reaction, ended up stealing the show. Along the way, we unpack route selection trade‑offs, lifecycle thinking in process chemistry, and what it really takes to bring an antiviral to life at scale.

    SE4:E7: From Discovery to Process, Part 1: Building a 3CL Protease Inhibitor Through Smart Fluorine Placement and Design Intuition

    In this first installment of our two‑part Pharm to Table special on MK‑7845, Dani and LC sit down with medicinal chemist Valerie Shurtleff to unpack the discovery journey behind this 3CL protease inhibitor—from early structural insights to an unexpectedly effective difluorobutyl isostere. Val walks us through how the team balanced potency, VLE, metabolic challenges, and design intuition to land on a well‑rounded preclinical candidate - one of the most dynamic programs of her career. Along the way, she reminds us why asking good questions, collaborating relentlessly, and occasionally surviving a “Hot Ones” challenge are all essential scientific skills. It’s an episode packed with chemistry, creativity, and just enough fluorine to keep things spicy. Stay tuned for Part 2, where we shift from invention to implementation and explore how the process chemistry team brought MK‑7845 to life at scale.

    SE4:E5 - Evolution of a Green Chemistry Trailblazer

    In this episode, Dani and LC welcome Jeff Moore, recipient of the 2025 ACS Affordable Green Chemistry Award, to discuss his pioneering work in biocatalysis at Merck. The conversation explores the evolution (pun intended) of biocatalytic processes in pharmaceutical manufacturing, highlighting key milestones such as the adoption of transaminases and imine reductases, and their impact on drug synthesis and sustainability. Jeff shares stories from his career, including how being 'lazy' when doing science can lead to major innovations and the practical benefits of enzyme-driven chemistry. He even leaves us with insights into the future frontiers of biocatalysis, from cascade reactions to microfluidics.

    SE4:E4 - MedChem Masters: Molecules, Mentors and Mindsets

    In this episode, Dani and LC interview Dr. Shane Krska, recipient of the ACS Arthur C. Cope Award, and Dr. Petr Vachal, recipient of the ACS Earle B. Barnes Award for Leadership in Chemical Research Management. Shane shares his pioneering work in catalytic methods and high-throughput experimentation (HTE) for drug discovery, while Petr discusses his leadership role driving innovation at Merck. They reflect on their career journeys from graduate school to industry, emphasizing personal growth and the importance on taking on diverse roles. We wrap it up by asking Shane and Petr what has made them the most proud over their 20+ year careers - which spans from innovations in direct-to-biology for accelerating design-make-test to advancing peptides as a modality of the future!
