Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lycopene (LYC) has poor chemical stability and low bioavailability, limiting its effectiveness as an antioxidant for treating male reproductive dysfunction due to easy oxidation, and existing treatments do not effectively target the testis for therapeutic delivery.
Innovation Solution
A testis-targeted LYC/ZIF-90 nanocomposite is developed, where LYC is bound to a ZIF-90 metal-organic framework (MOF) through aldol condensation, and follicle-stimulating hormone (FSH) is loaded on the nanocomposite to enhance bioavailability and therapeutic targeting, utilizing the MOF's pH-responsive properties to release LYC in inflammatory environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lycopene is used as an antioxidant for treating male reproductive dysfunction, then the therapeutic effect is improved, but the chemical stability and bioavailability deteriorate due to easy oxidation
Solution Approach 1:
The patent creates a composite nanocomposite material consisting of lycopene encapsulated within ZIF-90 metal-organic framework nanoparticles. This composite structure combines the antioxidant properties of lycopene with the protective and stabilizing characteristics of the ZIF-90 framework, preventing oxidation while maintaining therapeutic efficacy. The ZIF-90 acts as a protective shell that shields the labile lycopene from environmental oxidation.
Solution Approach 2:
The ZIF-90 metal-organic framework forms a nanoscale shell or film around the lycopene molecules, creating a protective barrier that prevents direct contact between lycopene and oxidizing environments. This thin film structure maintains the integrity and stability of the encapsulated lycopene while allowing controlled delivery to the target tissue.
2Reliability
If lycopene is administered to achieve therapeutic effect, then the antioxidant activity is improved, but the bioavailability deteriorates due to poor stability
Solution Approach 1:
The lycopene-ZIF-90 nanocomposite enhances bioavailability by combining lycopene with the biocompatible ZIF-90 framework. The nanoscale composite structure improves solubility, protects against degradation during circulation, and facilitates cellular uptake, thereby increasing the quantity of active lycopene that reaches the target tissue compared to free lycopene administration.
Solution Approach 2:
The patent changes the physical and chemical parameters of lycopene by encapsulating it within the ZIF-90 framework. This transformation alters the solubility, stability, and cellular permeability parameters of lycopene, converting it from a poorly bioavailable compound into a nanocomposite with enhanced pharmacokinetic properties and improved delivery to testicular tissue.
3Device complexity
If conventional treatments are used for male reproductive dysfunction, then the treatment approach is simple, but the testis targeting capability deteriorates
Solution Approach 1:
The ZIF-90 nanocomposite is designed with local quality characteristics that enable testis-specific targeting. The nanoparticles possess surface properties and size characteristics optimized for renal filtration and testicular accumulation. The FSH conjugation provides localized targeting to testicular tissue through receptor-specific binding, concentrating the therapeutic effect at the desired location while maintaining a relatively simple overall treatment approach.
Solution Approach 2:
The patent introduces FSH (follicle-stimulating hormone) as an intermediary targeting molecule conjugated to the ZIF-90 nanocomposite. This intermediary acts as a mediator that guides the nanoparticle to testicular tissue by binding to FSH receptors on testicular cells. This targeting mechanism adds specificity without requiring complex treatment protocols, as the FSH-nanoparticle conjugate passively targets the desired tissue through biological recognition.

AI summary
The present disclosure provides a testis-targeted lycopene (LYC)/ZIF-90 nanocomposite and a preparation method and use thereof, belonging to the technical field of targeted drugs. In the present disclosure, a ZIF-90 metal-organic framework (MOF) material is combined with LYC through aldol condensation; when entering areas of inflammatory response and oxidative stress response, ZIF-90 may disintegrate and collapse in a slightly-acidic environment, releasing the LYC, thereby avoiding easy oxidation of the LYC and improving a bioavailability of the LYC; in addition, the disintegrated and collapsed ZIF-90 may also be utilized by organisms, thus greatly reducing a damage to the organisms. Moreover, the LYC/ZIF-90 nanocomposite is further loaded with follicle-stimulating hormone (FSH). The FSH can specifically bind to a follicle-stimulating hormone receptor (FSHR) of a Sertoli cell to improve testicular targeting of the LYC/ZIF-90 nanocomposite, thereby improving a therapeutic effect of male reproductive dysfunction.
