GAITHERSBURG, Md., Oct. 10, 2025 (GLOBE NEWSWIRE) -- Shuttle Pharmaceuticals Holdings, Inc. (Nasdaq: SHPH) (“Shuttle Pharma” or the “Company”), a discovery and development stage specialty pharmaceutical company, today announced the execution of a non-binding letter of Intent with Molecule.ai.

Molecule.ai, a pioneering artificial intelligence company founded by AI scientist and researcher Dr. ZT Zhang, PhD, today announced the execution of a letter of Intent to acquire Molecule.ai and its state-of-the-art platform designed to transform the way pharmaceutical and biotech companies discover and develop new therapeutics.

By leveraging advanced machine learning models, including large language models (LLMs), Molecule.ai delivers industry-leading accuracy and efficiency in evaluating novel molecules. The platform enables researchers to shorten development timelines, reduce costs, and increase the likelihood of identifying successful therapeutic candidates.

“Our vision is to empower scientists with the most advanced AI-driven tools to push the boundaries of drug discovery,” said Dr. ZT Zhang, Founder and CEO of Molecule.ai. “With Molecule.ai, we are not just accelerating the process — we are fundamentally changing what’s possible in the search for new therapies.”

The Molecule.ai platform introduces several groundbreaking capabilities:

1. Molecule Property Prediction and Reasoning – Rapid and large-scale evaluation of chemical and biological properties across massive compound libraries, including novel and previously uncharacterized molecules.
2. Drug-Target Interaction Modeling – A powerful new feature that identifies and optimizes molecule-target interactions, paving the way for more precise therapeutic design.
3. Agentic AI Mode – An autonomous framework that enables AI agents to perform multi-step drug discovery workflows, from compound screening through optimization, significantly reducing manual effort.
   

With these innovations, Molecule.ai positions itself as a trusted partner for pharmaceutical and biotechnology organizations aiming to accelerate discovery and bring life-saving treatments to market faster.

Terms of the non-binding letter of Intent are as follows:

Shuttle will acquire all of the rights, title and interests Molecule.ai has free and clear of all liens.
