"Drug Hunter is like a well-stocked library and a front-row conference seat rolled into one, offering both historical perspective and cutting-edge updates on drug discovery," say Mark Murcko, a 21-year Vertex veteran and founding CSO of both Relay Therapeutics and Dewpoint Therapeutics.

"The team blends rigorous analysis with a deep appreciation for the craft of making medicines,” he continues.

“This site is a rare place where science, strategy, and storytelling come together to illuminate how great drugs are made.

“It's the kind of resource I wish had existed earlier in my career—and one I now recommend to everyone in the field."

The last line is one we hear a lot. At Drug Hunter, we’re on a mission to help drug discovery teams make better strategic decisions and we’re honored to receive this feedback from leaders in the industry.

Thank you, Mark, for the kind words!

Warhead Reactivity Cheat Sheet | https://drughunters.com/4gJluyP

Covalency is a well-established mechanism of action that can offer unique opportunities. In the design of such compounds, understanding relative reactivity can serve as a useful tool in mediating binding kinetics, potency, off-target reactivity and compound stability.

Take a look at our covalent warhead reactivity cheat sheet, which catalogs the relative reactivity of several common, and some more recent, functional groups used for targeted covalent inhibition.

Hopefully this cheat sheet will serve as a useful tool in the design and optimization of novel covalent compounds by teams across modalities and disease areas.

Next-Gen Utrophin Modulators for DMD: Learning from Clinical Setbacks https://drughunters.com/4ctvLww
Thursday, September 17th, 2026
8 AM PT | 11 AM ET | 5 PM CET

Duchenne muscular dystrophy is a severe X-linked muscle-wasting disorder caused by mutations in the dystrophin gene, for which no curative treatment currently exists. In this Flash Talk, Russell, Professor of Medicinal Chemistry in the Departments of Chemistry and Pharmacology at the of Oxford, will present the discovery and clinical development of ezutromid, a first-in-class small-molecule utrophin modulator identified through phenotypic screening. She will discuss the early clinical data supporting the program and the findings that ultimately led to its discontinuation. Angela will also highlight mechanistic studies identifying AhR (aryl hydrocarbon receptor) as the molecular target of ezutromid and will highlight next-generation AhR antagonists with improved properties and efficacy as well as screening strategies leading to the identification of utrophin modulators with a distinct mechanism of action. Sign up now to learn more about utrophin modulators acting through AhR antagonism for the treatment of DMD and novel MoAs for utrophin modulation: https://drughunters.com/3SNxZjy

Iberdomide Receives Accelerated FDA Approval for Multiple Myeloma as the First CELMoD | https://drughunters.com/466ZqIf

Iberdomide (Zenbexus®), a CRBN-mediated molecular glue degrader of IKZF1 (Ikaros) and IKZF3 (Aiolos), received accelerated FDA approval for the treatment of multiple myeloma in August 2026, representing the first CELMoD in an new era for the IMiD class of drugs.

The essential role that IKZF1 and IKZF3 play in blood and immune cell development makes their over-activation a central part of plasma cell malignancies—and the degradation of these proteins has been clinically validated therapeutic strategy in multiple myeloma.

Check out our profile on iberdomide’s development to learn:
- The historical context of IKZF degraders in hematological malignancies
- The biological rationale for iberdomide’s development for treatment of lupus and multiple myeloma
- Key clinical results, including the approval-enabling surrogate endpoint

Structure's Oral GLP-1 Contender Aleniglipron Gears Up for Ph. 3 | https://drughunters.com/4zN0yhL

Structure Therapeutics’ aleniglipron is a small-molecule GLP-1R agonist designed to bring incretin-like efficacy into a more scalable, oral format.

The molecule is entering a competitive landscape shaped by injectable blockbusters such as semaglutide and tirzepatide, an approved oral formulation of semaglutide, and emerging oral small-molecule contenders including Chugai/Eli Lilly’s orforglipron.

Recent Ph. 2b ACCESS data showed clinically meaningful weight loss, with no apparent plateau at week 36 and continued weight reductions in the open-label extension.

The key question now is whether aleniglipron can differentiate not only on efficacy, but also on tolerability as Structure advances toward Ph. 3.

Lessons from Recently Approved Oral Small Molecules: Dose Regimens, PK, and Safety
https://drughunters.com/3T7pCzx
Thursday, September 10th, 2026
8 AM PT | 11 AM ET | 5 PM CET

Small molecule drug discovery requires the balance of several factors such as potency, PK, safety, and developability. However, the profiles of clinically successful molecules are often broader than conventional optimization guidelines might suggest.

In this Flash Talk, Dean Brown, Senior Vice President and Head of Discovery Sciences at Jnana Therapeutics, will present an analysis of 104 oral small molecule drugs approved by the FDA between 2020 and 2024, examining approved dose regimens, human PK, safety, and DDI. He will highlight examples of successful drugs with properties that fall outside of traditional expectations and discuss how these can help medicinal chemists better understand the risks and tradeoffs that can be tolerated in the design of future small-molecule medicines.
