We have recently switched to StarDrop from Optibrium and it has been super user friendly.
Co-Founder and Chief Science Officer, Sunflower Wellness
StarDrop is a very compelling package – multiple powerful tools combined into a single piece of software accessed via a very intuitive user interface. The ease with which powerful MPO scoring functions and QSAR models can be generated and applied to new ideas, as well as the ability to predict metabolic liabilities, make StarDrop the go-to software for ensuring project progression.
Medicinal Chemist, Evotec
We routinely use StarDrop to visualise complex multi-parameter datasets, which helps inform the next stage of medicinal chemistry design. The user-friendly interface makes data analysis and property prediction easily accessible to medicinal chemists. A great drug discovery tool!
Director, Cerevance
Optibrium tools have proven instrumental during our lead optimization programs and beyond. Particularly, the metabolism module provided valuable guidance on design level during optimization cycles and substantially accelerated structure elucidation during Met-ID studies.
Head of Chemistry, Basilea
We use StarDrop for numerous functions, from the mundane to the elaborate. It’s an incredibly user-friendly, yet powerful piece of software… Our usage spans the entire medicinal chemistry spectrum; from hit triage to the processing of pre-clinical data.

StarDrop is a fantastic tool to have as a medicinal chemist, whether you do early-stage medicinal chemistry or deal with a huge amount of data. It’s super quick – I can have a view on my SAR within five minutes, to inform future design strategies.
Medicinal Chemist, adMare Bioinnovations
I really would like to give a big thumbs up to StarDrop and your team. StarDrop is a powerful package tool with an intuitive user interface to access and operate. We really appreciate the visualization module and probabilistic scoring system, which can well-organized interactive charts, graphics and chemical space to facilitate our understanding of the SAR in our chemical series.
Investigator, IFF
The relative ease of use of StarDrop, compared to other drug design and discovery software, allows my students to quickly focus on essential topics, such as ADME, QSAR, metabolism studies, and protein-ligand docking.
