About US

Silexon is an emerging AI-empowered technology company which aims to create an open AI platform for strategic collaboration in order to facilitate data-driven life science research and empower drug R&D process, and ultimately provide patients with greater access to innovative drugs for unmet medical needs.

We are the only AI-driven company that has established strategic collaobrative relationship with two leading CROs (i.e. Bioduro and Viva) with respect to AI modeling as well as co-promotion of each other's capabilities.

Silexon has reached co-development agreement with about 20 partners including but not limited to MNCs, public pharma companies, biotech companies and regulatory agency.

We have developed and have been continuously optimizing several generations of proprietary Drug-Target-Interaction models within our AI4D™ platform which leverage our inter-disciplinary capabilities and know-how.

Our AI/ML models integrate sequence-, structure-, interaction and ligand-based information in order to efficiently find hits and leads.

Technological Platform

AI4D™ - AI for Drug Discovery, Design and Development

Our AI/ML platform (i.e. AI4D™) is focused on early drug discovery for small molecules, with several generations of proprietary Drug-Target-Interaction models, and we have additional proprietary models for target ID, molecule generation, DMPK, toxicity/DILI, and more.

Silexon is seeking partners to work closely on FIC and difficult-to-drug targets, and also on repurposing opportunities.

Switch to know more models

Network based
Achieve substantial performance improvement over other state-of-the-art methods for drug–target interaction prediction
NeoDTI: a new nonlinear end-to-end learning model, which integrates diverse information from heterogeneous network data and automatically learns topology-preserving representations of drugs and targets to facilitate DTI prediction
Achieve substantial performance improvement over other state-of-the-art DTI prediction methods
Robust against a wide range of hyperparameters and ready to integrate more DTI information such as binding affinity
Sequence based
Sequence Model description: a novel general and scalable computational framework that combines effective feature embedding with powerful deep learning methods to accurately predict compound-protein interactions (CPIs) at a large scale, with superior predictive performance compared to baseline methods, capable to predict structure-free CPIs
Prediction Accuracy above 90%
Applicable in Virtual High-throughput Screening for FIC and difficult-to-drug targets, 3-6 hours for 1M molecule screening for drug discovery
Wet-lab validation can be reduced to the scale of 100 and fewer, with capabilities to identify allosteric hits/leads
Interaction based
Model description: a multi-objective neural network to predict both non-covalent interactions and binding affinity for a given compound-protein pair, with interpretability of the identified local features for compound-protein pairs, and provide useful insights about the molecular mechanisms of compound-protein interactions, help advance the drug discovery process
Applicable in first-in-class and fast follow drug discovery projects
Outperform other state-of-the-art methods in predicting compound-protein binding affinities
Next-gen Model
Model description: a next-generation multi-objective neural network to predict both non-covalent interactions and binding affinity for a given compound-protein pair, leveraging SBDD, FBDD, LBDD and interpretability of the identified local features for compound-protein pairs, and provide useful insights about the molecular mechanisms of compound-protein interactions, help advance the drug discovery process
Applicable in first-in-class and fast follow drug discovery projects
SILEXON aims at developing practical AIDD models

SILEXON’s solutions for challenges in AIDD

Model designs based on biological and medicinal chemical knowledge

Rich experience and systematic methodologies on biological tasks (including modeling sequences, structures, compounds, omics and network data and related problems)

Iteratively updated key models with superior performance and successful application cases;

Four generations of DTI models with high hit identification rates, for targets of all categories (first-in-class, difficult-to-drug targets, allosteric modulators, fast follow and repurposing)

Two developing DTI models with novel improvements: 1) an AI+CADD model learning from molecular dynamics (MD) to achieve both efficiency and accuracy (one million times speed-up); 2) an integrated model for SBDD+FBDD+LDBB+interaction

AI4Pat (automatic patent analysis) for extracting valuable data from patents: combined with high-throughput techniques and in vitro biochemical assays, the obtained data can be used to iteratively optimize the models (forming up a model-data-drug-model loop)
