AI-ACCELERATED DRUG DISCOVERY
Available from Reaxense
This protein is integrated into the Receptor.AI ecosystem as a prospective target with high therapeutic potential. We performed a comprehensive characterization of Neutrophil elastase including:
1. LLM-powered literature research
Our custom-tailored LLM extracted and formalized all relevant information about the protein from a large set of structured and unstructured data sources and stored it in the form of a Knowledge Graph. This comprehensive analysis allowed us to gain insight into Neutrophil elastase therapeutic significance, existing small molecule ligands, relevant off-targets, and protein-protein interactions.

2. AI-Driven Conformational Ensemble Generation
Starting from the initial protein structure, we employed advanced AI algorithms to predict alternative functional states of Neutrophil elastase, including large-scale conformational changes along "soft" collective coordinates. Through molecular simulations with AI-enhanced sampling and trajectory clustering, we explored the broad conformational space of the protein and identified its representative structures. Utilizing diffusion-based AI models and active learning AutoML, we generated a statistically robust ensemble of equilibrium protein conformations that capture the receptor's full dynamic behavior, providing a robust foundation for accurate structure-based drug design.

3. Binding pockets identification and characterization
We employed the AI-based pocket prediction module to discover orthosteric, allosteric, hidden, and cryptic binding pockets on the protein’s surface. Our technique integrates the LLM-driven literature search and structure-aware ensemble-based pocket detection algorithm that utilizes previously established protein dynamics. Tentative pockets are then subject to AI scoring and ranking with simultaneous detection of false positives. In the final step, the AI model assesses the druggability of each pocket enabling a comprehensive selection of the most promising pockets for further targeting.

Background:
Neutrophil elastase, also known as Bone marrow serine protease, Elastase-2, Human leukocyte elastase, Medullasin, and PMN elastase, plays a pivotal role in the immune system. It modifies the functions of natural killer cells, monocytes, and granulocytes, and is involved in the inhibition of C5a-dependent neutrophil enzyme release and chemotaxis. Additionally, it possesses the ability to kill E.coli and digest ompA in E.coli and K.pneumoniae, showcasing its antimicrobial properties.
Therapeutic significance:
Neutrophil elastase is linked to diseases such as Cyclic haematopoiesis and Severe congenital neutropenia 1, autosomal dominant, both of which involve hematopoiesis disorders. Understanding the role of Neutrophil elastase could open doors to potential therapeutic strategies for these conditions, highlighting its importance in medical research and drug discovery.
