What It Is

Cepos InSilico GmbH is a German developer of computational chemistry and molecular modeling software. Its products are centered on “surface-based modelling,” with key tools including EMPIRE, ParaSurf, EH5cube, CImatch, CADDLE, and SAR-caddle. The text indicates that its software is used by Sanofi Frankfurt and is aimed at materials science, drug design, biomolecular property research, and QSAR/QSPR modeling.

Core Capabilities

EMPIRE is a parallel semi-empirical molecular orbital program that can run on multi-core desktops as well as large-scale supercomputers. The text states that it has been tested on non-periodic systems of up to 100,000 atoms and periodic repeat units of up to 50,000 atoms, and supports various Hamiltonians such as MNDO, AM1, PM3, PM6, RM1, hpCADD, and MNDO-F. ParaSurf uses output from semi-empirical molecular orbital programs to construct molecular surfaces and calculate local properties, descriptors, and solvation-related properties. EH5cube reads EMPIRE HDF5 wavefunction files and generates Gaussian cube files. CImatch performs molecular alignment based on isodensity surfaces and properties such as electrostatic potential and local ionization energy. CADDLE and SAR-caddle provide browser-based modeling, 3D visualization, and QSAR/QSPR analysis.

Pricing and Licensing

The product line uses annual rental licenses. Industrial editions typically include support, maintenance, and upgrades, while academic editions generally do not include support or upgrades. Pricing varies widely: the SAR-caddle industrial site license is €2,500/year, CImatch is €10,000/year, EMPIRE20 single-node site license is €25,000/year, the multi-node version is €50,000/year, and the Cepos Suite industrial site license goes up to €75,000/year. Qualified academic users can obtain low-cost site licenses, and some older single-seat academic licenses are free.

Pros and Cons

The strengths are its clear research-oriented positioning and coverage of the full workflow from quantum chemistry calculations and surface descriptors to file post-processing and QSAR modeling. Data flow between products is well defined, and formats such as HDF5, SDF, and cube help with analysis and visualization. Industrial licenses promise maintenance and upgrades. The drawbacks are that the commercial purchasing process is rather traditional, still relying heavily on PDF order forms, fax, or email; industrial pricing is high; the crawled text does not show modern API, SDK, command-line package management, cloud service, or automation integration capabilities; and the free academic versions do not include support.

Who It’s For and Access from China

It is better suited to computational chemistry, medicinal chemistry, materials simulation, and university research groups than to general software development teams. If you need high-performance semi-empirical quantum calculations, molecular surface property modeling, or QSAR/QSPR tools, it is worth including in your evaluation. The text does not provide information on access from mainland China, so its status is unknown.
