We are very happy to share that today is our first anniversary as a company! 
One year ago, we started Melius Organics with a clear goal: help scientists access the specialized molecules they need for breakthrough research. Today, we’re proud of what we’ve built – custom synthesis services that tackle the challenging chemistry and a growing catalog of unique compounds.
Thank you to all our clients, partners and supporters who trusted us 
Year two, here we come! 
We’re pleased to announce that Melius Organics is sponsoring the ERNDIM 2025 Workshop in Madrid this October 9th-10th.
This international workshop brings together more than 150 experts in metabolic diseases, focused on improving diagnosis and treatment standards.
We’ll be there to show how Melius Organics can help with our custom services and products for analytics and metabolomics.
Looking forward to connecting with colleagues in Madrid and supporting their metabolic disease research.
Yesterday was a special day for our team as we were recognized alongside other innovative companies from Tarragona for our work in advancing pharmaceutical research and development.
Thank you to BBVA and Diari de Tarragona for this honor, and congratulations to all the winners (Synkotech Biocompatible Materials 🥇 and Scandraw SL🥈) and finalists (aonchip, Hardman App, Jelly Pills, NT Sensors, Qbed Consulting, Outlogic, Xènia Pérez Serrano) who are driving innovation in our region 🙏. Also to all the people and institutions supporting us, especially REDESSA.
At Melius Organics, we’re dedicated to providing high-quality molecules that fuel scientific innovation. Our expertise in advanced chemistry enables researchers and organizations to accelerate new discoveries and bring breakthrough solutions to life⚗️
This recognition validates our commitment to innovation and proves that Tarragona is indeed a land of entrepreneurs! 🚀

We’re pleased to share the SuFEx Handle Fragment Library, developed in collaboration between Melius Organics and OTAVA ltd.
This library comprises 74,543 fluorosulfate and sulfamoyl fluoride-containing fragments, designed to enable covalent modification of proteins via Sulfur(VI) Fluoride Exchange (SuFEx) chemistry. As a second-generation “click” reaction, SuFEx provides robust, selective reactivity under mild conditions, making it particularly suitable for fragment-based covalent ligand discovery.
🔹 Targets key nucleophilic residues such as lysine, tyrosine, and histidine
🔹 Facilitates covalent inhibitor development, enzyme profiling, and bioconjugation
🔹 Well-suited for applications in chemical biology, proteomics, and structure-based drug design
🔹 All fragments are feasible, synthetically accessible, and available for virtual or physical screening
🔹 Compounds are prepared on demand using in-stock building blocks with a typical turnaround of ~3 weeks
The structural diversity and electrophilic tuning of this library make it a valuable resource for exploring underexploited covalent binding strategies, especially beyond cysteine targeting.

Last Friday, Melius Organics joined REDESSA’s Demo day to wrap up the Incubator 2024 program. It was a great experience sharing our project with investors and key players in the startup ecosystem. The program really helped us shape our ideas, refine our model, and officially kickstart our company.
We’re extremely grateful to REDESSA for this opportunity—especially to Daniel Duran for the amazing support. Special thanks as well to the TopBrandsConsulting® team (Oriol Garcés and Jaume Ramos i Subirana) for the valuable training. We can’t wait to see what’s next! 🚀🌱
