Group 1: ODesign Overview - ODesign was developed by a collaboration of institutions including Shanghai AI Laboratory and Harvard University, and it represents the first universal molecular design model [3]. - The model allows scientists to specify target sites on any type of target and achieve one-click design of proteins, peptides, nucleic acids, small molecules, and metal ions [11][12]. - ODesign significantly outperforms existing models like RFDiffusion and BindCraft in multiple industry-standard test sets, indicating a shift from "single-point breakthroughs" to "general intelligence" in generative AI drug development [4][12]. Group 2: Technological Advancements - ODesign achieves a nearly 50-fold increase in design efficiency compared to similar models, reducing the complete design cycle from days to hours [12]. - The model incorporates a new structural generation architecture with five core modules that enable multi-level representation of different molecular modalities and flexible control of conditions [16][20]. - It utilizes a cross-modal shared generative language to unify various molecular types into a common molecular generation space, allowing for collaborative construction based on atomic interactions [20]. Group 3: Performance Validation - ODesign has been tested across 11 molecular design tasks covering proteins, nucleic acids, and small molecules, demonstrating superior capabilities in protein design, including complex structures and functional optimization [23][26]. - In nucleic acid design, ODesign achieved approximately 60% and 20% RMSD success rates for 60nt RNA and DNA monomer design tasks, respectively [29]. - The model also excels in small molecule design, achieving about four times the success rate compared to mainstream models in targeting RNA [29][31]. Group 4: Practical Applications - The ODesign team has launched an online trial system for researchers and industry users, enabling rapid generation and visualization of high-quality molecular candidates [32][34]. - This platform aims to facilitate the transition from a research tool to a creative platform for AI-driven molecular creation, opening new avenues in drug development [32].

Core Viewpoint - The article discusses the breakthrough technology BindCraft, which allows for the one-shot design of functional protein binders with a success rate of 10%-100%, significantly improving the efficiency of protein design compared to traditional methods [2][3][5]. Summary by Sections BindCraft Technology - BindCraft is an open-source, automated platform for de novo design of protein binders, achieving high-affinity binders without the need for high-throughput screening or experimental optimization [3][5]. - The technology leverages AlphaFold2's weights to generate protein binders with nanomolar affinity, even in the absence of known binding sites [3][5]. Applications and Results - The research team successfully designed binders targeting challenging targets such as cell surface receptors, common allergens, de novo proteins, and multi-domain nucleases like CRISPR-Cas9 [3][7]. - Specific applications include: 1. Designing antibody drugs targeting therapeutic cell surface receptors like PD-1 and PD-L1, achieving nanomolar affinity without extensive design and screening [7]. 2. Blocking allergens, with a designed binder for birch pollen allergen Bet v1 showing a 50% reduction in IgE binding in patient serum tests [7][8]. 3. Regulating CRISPR gene editing by designing a new inhibitory protein that significantly reduces Cas9's gene editing activity in HEK293 cells [8]. 4. Neutralizing deadly bacterial toxins, with a designed protein completely eliminating cell death caused by the toxin from Clostridium perfringens [8]. 5. Modifying AAV for targeted gene delivery by integrating mini-binders that specifically target HER2 and PD-L1 expressing cancer cells [8]. Impact and Future Potential - BindCraft addresses long-standing success rate bottlenecks in protein design and offers direct solutions for allergy treatment, gene editing safety, toxin neutralization, and targeted gene therapy [9]. - The open-source nature of the technology allows ordinary laboratories to design custom proteins, potentially reshaping drug development, disease diagnosis, and biotechnology [9].
