Shining a new light on insurmountability

It's a new dawn, it's a new day. Every morning patients with immune diseases awake to face another day of coping with their debilitating conditions. But each day also brings hope, that someday there will be a cure.

Insurmountability unlocked:

At Artica we are driven by curiosity, passion and one common goal: to develop novel therapies for patients suffering from severe autoimmune and inflammatory disorders.

We leverage covalent chemistry to develop new medicines that potently and selectively inactivate disease-causing proteins over an extended period of time. Artica's covalent drugs display insurmountable binding by design, meaning that the drug continues to be active in case of excessive stimulation of the disease proteins.

It is our belief that covalent drugs can offer a more effective and safer treatment option, and therefore will not only benefit more patients, but also serve the individual patient better.

About us

Artica Therapeutics B.V. and its seasoned team started operations in 2020. The venture was supported by Pre-seed financing from BioGeneration Ventures in 2021, followed by a Seed round supported by Thuja, Seroba, InnovationQuarter and BioGeneration Ventures in 2023. Artica is dedicated to finding new small molecule drugs for inflammatory and autoimmune indications using innovative approaches.

Artica is a leader in the field of covalent binding technology and in label-free cellular-based screening approaches. The unique combination of these capabilities allows rapid progression of drug candidates that have unprecedented and superior characteristics, resulting in novel and highly selective therapies for patients with unmet medical needs.

“It’s the question that drives us”. Innovation is the answer.

Ad Ijzerman
SAB Chair

Ad IJzerman

Founder & SAB Chair

Ad joined Artica as a co-founder and SAB chair after his retirement from Leiden University, The Netherlands. There he led a large team working at the interface of structural biology, molecular pharmacology and medicinal chemistry. Ad’s main focus over the years has been the large superfamily of G protein-coupled receptors (GPCRs).

In 2008 his team co-authored one of the first (Science) publications describing the 3D structure of the adenosine A 2A receptor, followed by a number of similar high-profile papers. As a medicinal chemist Ad developed thousands of NCEs, covered by both patents and scientific publications.

He also pioneered novel receptor concepts such as inverse agonism, constitutive activity, allosteric modulation and drug target binding kinetics, all principles for which he constituted large European consortia. He is the recipient of many prizes, including the 2020 Nauta Award for Medicinal Chemistry and Chemical Biology from the European Federation of Medicinal Chemistry.

Ad received a Pharm D degree from Utrecht University and a PhD degree in medicinal chemistry from the Vrije Universiteit in Amsterdam, The Netherlands.
