To obtain a global overlook of the structure distributions of generated molecules, we present the ring number distribution of molecules generated by PMDM and the molecules in the test set and the train set (Fig. 3a). Although the dataset contains only 3% three-atom rings, AR methods generate more of these unstable structures, which means that these methods get stuck in local optima and fail to learn the data distribution well. Traditional in silico methods such as virtual screening discover molecules by iteratively (1) placing molecules from existing databases into the protein pocket cavity and (2) filtering the molecules based on criteria such as energy estimation4 and toxicity by experimental essays. Given a specific target protein, it aims to identify suitable drug molecules that effectively bind to a specific target protein. Structure-based drug discovery (SBDD) plays a crucial role in modern drug development1,2 and catalysis3. In short, identification finds the starting point and optimization refines it into a stronger candidate.
In practice, teams use lead optimization to balance potency, exposure, safety and manufacturability before selecting compounds for preclinical development. In silico methods such as QSAR, molecular docking and machine learning models help predict compound behavior, prioritize analogs and guide design decisions before additional synthesis and testing. Lead optimization relies on a mix of analytical and computational methods. These technologies help researchers understand molecular interactions, predict compound behavior and prioritize analogs for testing.
Validated hits, early structure-activity insights and initial developability data Together, these approaches help researchers explore chemical space more efficiently and identify compounds worth advancing. Common lead identification methods include high-throughput screening, virtual screening, molecular docking and machine learning-assisted prioritization. These early hits are then prioritized for lead optimization based on their overall drug-like profile. Because potency alone is not enough, successful lead optimization also considers manufacturability, developability and translational risk alongside efficacy.

Instrument-intensive and dependent on workflow integration and sample quality High analytical confidence and useful support for mechanism and exposure questions Requires repeated synthesis and testing; local improvements may not translate in vivo In real-world drug discovery, lead optimization helps teams decide whether to advance, redesign or deprioritize a scaffold based on potency, exposure, safety and manufacturability data.

In practice, lead optimization is an iterative process that combines medicinal chemistry, screening and computational analysis to improve a molecule's target engagement while reducing off-target effects and development risk. The goal is to turn an early active molecule into a more balanced drug candidate by improving ADMET performance and reducing development risk. Lead optimization in drug discovery is the process of refining a promising lead compound to improve potency, selectivity, safety and drug-like properties before preclinical development. Lead optimization is a core stage of drug discovery in which researchers refine promising lead compounds to improve potency, selectivity, safety and drug-like properties before preclinical development. The process of computationally placing a virtual molecular structure into a binding site of a biological macromolecule (docking) and flexibly or rigidly relaxing the respective structures then ranking (scoring) the complementarity of fit.

The binding data (pK) for the CrossDocked2020 set was obtained from PDBbind v2017, and it was observed that 41.9% of the complexes have available binding affinity data. The rings occupy the key binding sites (S1, S2, S3, and S4), which is key binding sites of Mpro. In order to investigate whether the generated molecules contain the same features, we first calculate the pharmacophore models using the software Align-It. As we mentioned before, compound 5 contains several features contributing to its high affinity with the Mpro. E The spatial distribution of the key pharmacophore groups of generated molecules with high affinities. To summarize, PMDM can correctly model the distribution of important 3D and 2D molecular structures and has the potential to guide a more comprehensive exploration to develop drug-like structures.

Lead optimization uses analytical, computational and experimental tools, such as NMR, mass spectrometry, QSAR, molecular docking and machine learning. Further, at the end of the lead optimization stage, the lead compounds are characterized using drug-induced metabolism and metabolic profiling, high-dose pharmacology and PK (pharmacokinetic)/PD (pharmacodynamic) studies. During lead optimization, researchers synthesize and test analogs of a lead compound to improve efficacy, selectivity, pharmacokinetics and safety. This stage is iterative and typically combines medicinal chemistry, SAR analysis, biochemical testing and ADMET evaluation.

These early hits are screened for properties such as selectivity, solubility and stability before moving into lead optimization. Lead identification in drug discovery is the process of identifying and selecting compounds with promising biological activity against a target. Biological systems are complex and strong in vitro performance does not always predict in vivo exposure, safety or clinical relevance. Lead optimization remains a high-risk stage because strong early data does not guarantee clinical success.
Practically, we set the local radius τl as 3 Å which could include almost all the chemical bonds and the global radius τg as 6 Å. Since directly calculating the likelihood is intractable, we adopt the variational lower bound (VLB)29 to optimize. The reverse process is designed to recover the real data G0 from the diffused data GT ~ p(GT) which is achieved by the diffusion process. The refined goal of the diffusion model is to learn the reverse process via a parameterized neural network.
Qualified lead optimization goal reporting metrics
Distinct three-dimensional forms of a molecular structure of a given atomic connectivity, which results from internal rotations about single bonds between atoms. A specific core or scaffolding structure that imparts a generic activity towards a protein family or limited set of its members independently of the specific substituents attached to it. Metrics used to numerically describe a structure or certain molecular attributes of a compound (for example, Tanimoto, Ghose and Crippen, BCUT and so on). A scoring metric (computational) for the similarity of a given structure to a representative reference set of marketed drugs.
Jing Han designed, supervised the in vitro biochemical assays Hailong Li designed, supervised syntheses of compounds. Different from the sampling strategy from scratch which samples the molecule noise from the standard Gaussian distribution, the given fragment information Gf should be fixed as a seed start point. For the generic structure-based molecule generation, we adopt this sample strategy. The goal of the diffusion model is to learn to reverse the diffusion process. In addition to the conditioned protein semantic information, we also need to consider the conditioned protein spatial information to ensure the generated ligand can fit the pocket structure without the clash issue. The one-hot encoded atom features and coordinates with the local edges and global edges are fed into the dual equivariant encoders, respectively.
Why Targeting Matters
Sophisticated multi-dimensional methods are used to characterize larger and more complex biomolecules. A spectroscopy tool used for the assignment and confirmation of chemical structure of a compound or biological macromolecule. The spatial orientation of various functional groups or features necessary for activity at a biomolecular target. Initial criteria are defined when hits are first identified; they include activity, selectivity and pertinent physicochemical properties, plus an evaluation of ADME and certain safety attributes.
