InteractionGraphNet: A Novel and Efficient Deep Graph Representation Learning Framework for Accurate Protein–Ligand Interaction Predictions

Journal of Medicinal Chemistry, Год журнала: 2021, Номер 64(24), С. 18209 - 18232

Опубликована: Дек. 8, 2021

Accurate quantification of protein–ligand interactions remains a key challenge to structure-based drug design. However, traditional machine learning (ML)-based methods based on handcrafted descriptors, one-dimensional protein sequences, and/or two-dimensional graph representations limit their capability learn the generalized molecular in 3D space. Here, we proposed novel deep representation framework named InteractionGraphNet (IGN) from structures complexes. In IGN, two independent convolution modules were stacked sequentially intramolecular and intermolecular interactions, learned can be efficiently used for subsequent tasks. Extensive binding affinity prediction, large-scale virtual screening, pose prediction experiments demonstrated that IGN achieved better or competitive performance against other state-of-the-art ML-based baselines docking programs. More importantly, such was proven successful features instead just memorizing certain biased patterns data.

Deep learning predicts boiling heat transfer

Scientific Reports, Год журнала: 2021, Номер 11(1)

Опубликована: Март 10, 2021

Boiling is arguably Nature's most effective thermal management mechanism that cools submersed matter through bubble-induced advective transport. Central to the boiling process development of bubbles. Connecting physics with bubble dynamics an important, yet daunting challenge because intrinsically complex and high dimensional dynamics. Here, we introduce a data-driven learning framework correlates high-quality imaging on dynamic bubbles associated curves. The leverages cutting-edge deep models including convolutional neural networks object detection algorithms automatically extract both hierarchical physics-based features. By training these features, our model learns physical laws statistically describe manner in which nucleate, coalesce, depart under conditions, enabling situ curve prediction mean error 6%. Our offers automated, learning-based, alternative conventional heat transfer metrology.

RELATION: A Deep Generative Model for Structure-Based De Novo Drug Design

Journal of Medicinal Chemistry, Год журнала: 2022, Номер 65(13), С. 9478 - 9492

Опубликована: Июнь 17, 2022

Deep learning (DL)-based de novo molecular design has recently gained considerable traction. Many DL-based generative models have been successfully developed to novel molecules, but most of them are ligand-centric and the role 3D geometries target binding pockets in generation not well-exploited. Here, we proposed a new 3D-based model called RELATION. In RELATION model, BiTL algorithm was specifically designed extract transfer desired geometric features protein-ligand complexes latent space for generation.
