GPCR-AI DISCOVERY PLATFORM
From receptor dynamics to therapeutic candidates.
Starting from molecular mechanism, we connect structure, computation, artificial intelligence and functional experiments in a rapid iterative system.

PLATFORM LOGIC
Prediction and experiment calibrate each other in every design cycle.
We do not treat AI as an isolated tool. It is embedded across GPCR mechanism research, structural analysis, molecular generation, virtual screening, property optimization and biological testing.

GPCR molecular research
Membrane proteins
in particular G protein-coupled receptors (GPCRs), are the most important drug targets. As an example, about 40% of the clinically used drugs are targeting GPCRs.
In some pharmaceutical companies, this figure can be even as high as 70-80%. Therefore, the understanding of membrane protein functions is of fundamental importance for modern drug discovery.

Innovative GPCR biotesting
G protein-coupled receptors
G protein-coupled receptors (GPCRs) are the most important drug targets, of which about 40% of the marketed drugs are targeting GPCRs.
As a membrane protein, the biological activity testing for GPCR drug discovery is still a challenging task. Many difficulties remain to be resolved including: (1) testing drug activity without labeling (2) measuring GPCR/G-protein interaction directly instead of determining that of cAMP or Ca2+ signaling in an indirect way (3) measuring kinetic properties of GPCR drug molecules and (4) differentiating G protein types inside cells.

In this regard, the team member of AlphaMol developed a series of innovative biochip technologies to overcome the hurdle in GPCR drug discovery in the past 20 years. Such breakthrough facilitates the process of GPCR drug discovery in a much more accurate and efficient way.

New drug discovery
AlphaMol
Modern drug discovery and development is a complicated process, which costs about $2-3 billion and lasts for 12 years on average. How to decrease the costs and speed up the process is the challenge. Computational biology and Artificial Intelligence, combined with new technologies in experimental drug screening, are expected to make the hunt for new drugs quicker, cheaper and more efficient.
Our team has established a sophisticated computer-aided drug discovery platform, which combines Artificial Intelligence, WebGL, cloud computing and big data. It can perform a wide range of drug discovery tasks such as molecular generation, virtual screening, lead optimization, drug property optimization, molecular dynamics simulation, accurate binding energy prediction and others. We have applied our tools successfully to discover and design potent drug candidates for various targets.
Members of our team have the experience of advancing designed molecules into clinical trials. More recently, we discovered a series of potent compounds for different orphan receptors. These compounds could result in "me-only" drug candidates.

Resolving membrane protein structures in real lipids
Membrane proteins
Membrane proteins are important drug targets which include G protein-coupled receptors (GPCRs), ion channels, transporters and others. Our team has close collaborations with leading scientist in the area of structural biology. However, most of current membrane protein structures were resolved at detergent or artificial lipid environments which are totally different from their physiological conditions. This in return result in losing the physiological functions of target membrane protein. Such structures will increase the cost the of structure-based drug discovery noticeably.
AlphaMol
Our team has developed a new pipeline which can resolve the membrane protein structures at real lipid environments. With such functional structures, we can design drug molecules in a more accurate way. Moreover, excellent cryoEM facilities are accessible in both China and Switzerland.

New computational algorithm development
AlphaMol
Our team has developed an absolute binding energy prediction tool, which is known as AlphaE. With the new algorithm of AlphaE, we can predict accurately the binding activity of a compound. The RMSE (root-mean-square-energy) is as low as 1 kcal/mol in comparison with experimental data. AlphaE also overcomes many difficulties in currently available tools such as: (1) predictions are not reliable when the molecule changes too much; (2) calculations cannot be performed if molecules bind to different pockets; (3) predictions need large amount of CPU and GPU resources.
Furthermore, AlphaMol also developed many new computational algorithm and tools to predict the physical properties and drug-likeness of molecules. These tools demonstrated perfect correlations with experimental data, of which the R2 is up to 0.99.
