Sesame: Structure-Aware Molecular Generation via Spatial Density-Map Conditioning

arXiv:2606.23856v1 Announce Type: new Abstract: Generative molecular models for drug design are a promising direction with much active research. In the next phase of computational drug design, such models will need to understand small molecule structure and protein-ligand interactions, and they will need to possess the machinery to generate molecules \textit{de novo}. Incorporating each feature poses a critical challenge. Equally important, yet often treated as secondary, is the ability to grow a molecule from a partial starting point -- a scaffold or fragment supplied by a chemist -- which is

Why this matters
Why now

This research continues the rapid advancements in AI for drug discovery, pushing towards more sophisticated molecular generation methods that incorporate structural and interaction data.

Why it’s important

Advanced generative models for de novo molecule design and scaffold growth could significantly accelerate and de-risk early-stage drug development, impacting pharmaceutical pipelines and therapeutic innovation.

What changes

The ability to generate molecules from partial starting points, conditioned on spatial density maps, enhances the precision and applicability of computational drug design, moving beyond purely de novo generation.
