Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of effective small-molecule NAMPT agonists to address the urgent need for treating neurodegenerative diseases and anti-aging, as current drugs only relieve early symptoms without preventing disease progression.
Innovation Solution
Development of a class of aromatic compounds with NAMPT activation effect, represented by specific structural formulas, which act as NAMPT enzyme agonists, enhancing NAMPT enzyme activity to promote NAD biosynthesis and offering potential therapeutic benefits for neurodegenerative diseases and anti-aging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If NAD precursors (NR, NMN, or NAM) are supplied to enhance NAD levels, then anti-aging and disease prevention effects are achieved, but the required dosage is very large and pharmacokinetic safety concerns arise
Solution Approach 1:
The patent introduces NAMPT agonists as intermediary compounds that mediate between the administered substance and the target NAD levels. Instead of directly supplying large amounts of NAD precursors, the agonists activate NAMPT enzyme to catalyze endogenous NAD synthesis, serving as a more efficient mediator that amplifies the therapeutic effect at lower dosages
Solution Approach 2:
The patent changes the mechanism parameter from direct substrate supply to enzyme activation. By targeting the NAMPT enzyme activity parameter rather than NAD precursor concentration, the therapy achieves better pharmacokinetic properties and reduced dosage requirements while maintaining therapeutic effectiveness
2Ease of operation
If current drugs are used to treat neurodegenerative diseases, then early symptoms are relieved, but disease progression cannot be prevented
Solution Approach 1:
The patent implements preliminary action by activating NAMPT enzyme to increase NAD levels before neurodegenerative damage occurs or progresses. The enzyme activation approach allows for preventive therapy that can stop disease progression before it becomes irreversible, rather than merely relieving symptoms after damage has occurred
Solution Approach 2:
The patent enables the body's own NAD synthesis machinery to serve the therapeutic purpose by activating endogenous NAMPT enzyme. This self-service mechanism allows cells to produce their own NAD locally through enzyme activation, providing sustained therapeutic effect without requiring continuous high-dose external precursor supplementation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The aromatic compounds effectively activate NAMPT, demonstrating good cytoprotective and anti-neurodegeneration effects in animal models, laying the foundation for innovative drugs and providing proof that enhancing NAMPT enzyme activity is crucial for neuroprotection.
Implementation Method 1
NAMPT is the rate-limiting enzyme in this NAD biosynthesis pathway, and its activity is essential for maintaining stable intracellular NAD levels

AI summary
The present invention provides a class of novel NAMPT enzyme agonist and preparation and use thereof, which has a structural formula as shown in formula I or formula II. The present invention screens the NAMPT agonist NAT from the chemical small molecule library, and the NAT exhibits a good cytoprotective effect and a good anti-neurodegeneration effect in animal models of neurodegeneration. We studied the binding of NAT to enzymes, and then carried out multiple rounds of structure optimization based on the chemical structure characteristics of NAT and its enzyme activity properties, and obtained a relatively defined structure-activity relationship. The present patent not only lays the foundation for developing innovative drugs for anti-aging and neurodegenerative diseases, but also theoretically provides a proof-of-concept that enhancing NAMPT enzyme activity plays an important role in neuroprotection.
