Optibrium creates elegant software solutions for small molecule design, optimisation and data analysis. Optibrium has three products ranging from its enterprise class StarDrop™ software, through its iPad® app Asteris™, to Ocura™ which can be downloaded for free.


StarDrop is a complete package of fully integrated, elegant software for small molecule design, optimisation and data analysis.

StarDrop helps you to deliver optimally balanced, successful compounds, fast. StarDrop enables a seamless flow from the latest data through predictive modelling to decision-making regarding the next round of synthesis and research, improving the speed, efficiency, and productivity of the discovery process.

StarDrop’s core features can be extended with a comprehensive range of optional plug-in modules: predictive models for ADME properties, P450 metabolism and toxicity; automatic QSAR model building; 3D SAR analysis; and de novo design to stimulate the search for new optimisation strategies.


Asteris is an iPad® app for drug discovery that gives creative scientists the power to quickly explore high quality compound ideas, anywhere, at any time. Asteris combines best-in-class chemistry drawing tools with the most visually informative predictive modeling available on app or PC. With Asteris you’re free to evaluate new compound ideas when and where you want, no longer limited to sitting in an office or in front of a computer; Asteris makes the best use of your time.

Asteris uses Chirys Draw’s™ state-of-the-art touch interface to deliver an innovative ideas space, enabling you to explore a much wider range of designs, beyond the constraints of traditional computational tools. Using StarDrop’s predictive modelling power, guided by the Glowing Molecule™ visualization, instant feedback dramatically reduces the time it takes you to identify high quality compound designs. And because the Asteris platform is mobile, you can easily improve ideas by quickly sharing and collaborating with team members.


This free and easy-to-use Windows® and Mac® desktop application is specifically designed for scientists who want a simple way to load a set of molecule structures and easily browse through the data. Ocura enables you to simply load, scroll though, sort and manage data in a new way, providing the ability to view and manipulate chemical structures.
