Molecular Modeling, Simulation & AI Drug Discovery Software

MolCube has been developing a global-leading computational platform to provide an ultimate solution for modeling and simulation of complex biomolecular and/or material systems that enables drug and material discovery.

Overview

MolCube-Designer

MolCube-Designer is for AI-based model generation, automatically proposing and creating diverse molecular structures such as proteins, ligands, and complexes. It streamlines the design process, expands the scope of exploration, and helps researchers validate hypotheses more efficiently.

MolCube-Builder

MolCube-Builder is for complex model building and simulation input generation. MolCube-Builder does not require any commercial third-party software and will be available as a web server or can be installed locally or in your cloud system. 

MolCube-Simulator

MolCube-Simulator is for job submission to designated cloud systems and job management.

MolCube-Analyzer

MolCube-Analyzer is for simulation trajectory analysis on designated cloud systems.
