3DLinker: An E(3) Equivariant Variational Autoencoder for Molecular Linker Design

1 code implementation15 May 2022 Yinan Huang, Xingang Peng, Jianzhu Ma, Muhan Zhang

The main computational challenges include: 1) the generation of linkers is conditional on the two given molecules, in contrast to generating full molecules from scratch in previous works; 2) linkers heavily depend on the anchor atoms of the two molecules to be connected, which are not known beforehand; 3) 3D structures and orientations of the molecules need to be considered to avoid atom clashes, for which equivariance to E(3) group are necessary.
