This study revisits this well-explored area by leveraging the advanced capabilities of modern computational resources. We apply an automated network optimizer model that integrates dual optimization processes for molecular features and hyperparameters, streamlining the traditionally complex hyperparameter search while providing an efficient interpretation of molecular properties. By employing feature optimization techniques, our deep neural network model demonstrates improvements in both the speed and accuracy of molecular property predictions, achieving an average performance of R² = 0.991. This result outperforms conventional hyperparameter optimization methods such as grid search and random search in predicting the intrinsic solubility of 3,745 compounds across four external experimental datasets. Based on feature importance analysis, we identified key molecular features and structures that significantly influence solubility. Additionally, combining three molecular fingerprints (Morgan, MACCS key, and Avalon) with molecular descriptors enhances model performance, providing a deeper understanding of the relationship between molecular structure and solubility within the physicochemical feature optimization process. These findings underscore the potential of machine learning models to improve predictive modeling of physical properties, apply automated modeling and feature selection to new chemical datasets, and offer explainable insights into the principles driving solubility predictions.Scientific contributionsThis article focuses on recent advancements in the prediction of molecular properties through the application of a Quantitative Structure-Property Relationship (QSPR)-based deep neural network (DNN) model. This model employs a dual optimization approach that integrates both molecular feature selection and hyperparameter tuning. A review of publicly available datasets for drug-sized molecules is presented, highlighting the contributions of automated modeling and feature selection in enhancing the predictive accuracy of physical properties.

However, assessing their performance remains challenging due to the structural diversity and volume of the generated molecules. Commonly used evaluation metrics, focusing on chemical validity and novelty, do not fully align with the primary goal of molecular generation: the discovery of new biologically active compounds. To address this limitation, we introduce scaffold-based metrics that enable a fair comparison by evaluating a generator's ability to recover biologically relevant scaffolds absent from the input set. We applied the scaffold Recovery Score (RS), SEt scaffold Diversity (SED), and Absolute SEt scaffold Recall (ASER) metrics to compare several molecular generators, including Molpher, DrugEx, REINVENT, and Graph-based genetic algorithm. The proposed scaffold-based metrics provide a realistic framework for evaluating and optimizing molecular generators for their practical use in drug discovery scenarios, particularly in the design of focused virtual chemical libraries.

While artificial intelligence offers powerful tools for modeling chemical reactions, current approaches are primarily limited to two paradigms: those that rely on hand-crafted, domain-specific features, and those that apply generic deep learning models through simplistic concatenation or aggregation of reaction components. The former often struggles to scale effectively with increasing data volumes, while the latter relies on simple input- or feature-level concatenation to combine different reaction components. Such simplistic aggregation prevents these models from directly capturing the structural transformations between reactants and products, and also makes it difficult to adapt or extend them to datasets that include non-molecular reaction conditions without modifying their model architectures.</p><p><strong>Results: </strong>This paper introduces AlignReact, a novel chemical reaction representation learning framework designed for a wide range of organic reaction tasks. Our approach integrates atomic correspondence between reactants and products to discern precise molecular transformations, thereby improving the model's comprehension of molecular transformation patterns. We incorporate an adapter structure to embed reaction conditions into the representation, enhancing adaptability across varied datasets and tasks. Furthermore, a Reaction-Center-Aware attention mechanism is proposed to enable the model to focus on critical functional groups, yielding more powerful and informative representations.

Inspired by conditioning mechanisms from multimodal generation, this adapter module accepts precomputed features of varying dimensions and modalities, laying the groundwork for broader dataset compatibility compared to prior work, and enables fine-grained, context-aware conditioning.

In this work, we propose a novel taxonomy of 67 classes related to peptides, a large branch in ChEBI with nearly 15,000 compounds. The existing natural language definitions in ChEBI have been expanded and specified more precisely. These natural language definitions are accompanied by a logical axiomatisation in monadic second-order logic (MSOL). To use the axiomatisation for automated classification, a methodology has been developed that translates monadic second-order definitions first into partial first-order definitions and finally into an algorithmic classification. This connects three aspects important to ontological definitions: They reflect the opinions of experts, they are unambiguous, and they can be checked automatically. In our evaluation, we compare the results of our classification to the current taxonomy of ChEBI . This reveals potential inconsistencies in ChEBI as well as areas that might benefit from automated extensions.

Deep learning has substantially improved OCSR performance, yet most methods rely on synthetic training data and struggle to generalize to real-world inputs, especially hand-drawn diagrams, where stroke width, geometry, and drawing conventions vary widely across individuals. In this work, we propose an image-to-graph model AdaptMol that enables effective transfer from synthetic to real-world data without requiring manual graph annotations in the target domains. AdaptMol is an integrated pipeline that starts with training a base model on synthetic data, and then refines model representations through unsupervised domain adaptation and self-training. Our key insight is that bond features are domain-invariant in nature; they encode structural relationships between atoms that are independent of visual variations across domains. Thus, during domain adaptation, we align bond-level feature distributions via class-conditional Maximum Mean Discrepancy (MMD) to enforce cross-domain consistency. We also design a comprehensive data augmentation strategy to enhance the robustness of the base model, facilitating stable self-training on unlabeled target samples. On hand-drawn molecular images, our model achieves 82.6% accuracy and outperforms the best prior method by 10.7 points, while maintaining competitive performance across four benchmarks comprising molecular images from scientific literature and patent documents.Scientific contributionWe propose AdaptMol, an image-to-graph model that predicts molecular structures as graphs of atoms and bonds, achieving effective transfer from synthetic to hand-drawn molecular images without requiring target domain graph annotations.
