Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cancer treatments from natural plants have limitations in effectively targeting and inhibiting cancer cells, particularly liver, breast, and lung cancer cells, with existing flavonoids showing weak cytotoxicity and lack of selectivity for cancer cells.
Innovation Solution
The extraction and preparation of novel flavonoid compounds from Thelypteris torresiana, specifically protoapigenone, 5′,6′-dihydro-6′-methoxyprotoapigenone, protoapigenin, and 5,7-dihydro-2-(1-hydroxy-4,4-dimethoxy-cyclohexyl)-chromen-4-one, which are processed using methanol and ethyl acetate extraction followed by chromatography to achieve strong cytotoxic activities against cancer cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional flavonoids are used for cancer treatment, then low toxicity is achieved, but cytotoxic activity against cancer cells is weak
Solution Approach 1:
The patent extracts and isolates specific flavonoid compounds (protoapigenone, 5′,6′-dihydro-6′-methoxyprotoapigenone, protoapigenin) from the plant Thelypteris torresiana through systematic extraction and chromatography processes. This extraction of active components from the crude plant material resolves the contradiction by concentrating the cytotoxic principles while maintaining the low toxicity profile inherent to natural flavonoids.
Solution Approach 2:
The patent identifies and isolates specific flavonoid compounds with distinct chemical structures and localized cytotoxic properties. By focusing on particular compounds rather than crude extracts, the invention achieves enhanced cytotoxic activity against cancer cells while preserving the selective low toxicity characteristic of flavonoids, thus resolving the contradiction between potency and safety.
2Ease of manufacture
If flavonoids are used for cancer treatment, then low cost and natural origin are achieved, but selectivity for cancer cells is insufficient
Solution Approach 1:
The patent employs extraction and chromatography techniques to isolate specific flavonoid compounds from Thelypteris torresiana that exhibit selective cytotoxicity. This extraction process resolves the contradiction by obtaining pure compounds with enhanced cancer cell selectivity while maintaining the cost-effectiveness and natural origin advantages of plant-based therapies.
Solution Approach 2:
The patent changes the chemical parameters by isolating specific flavonoid compounds with particular structural characteristics (protoapigenone, 5′,6′-dihydro-6′-methoxyprotoapigenone, protoapigenin) that possess improved selectivity for cancer cells. This parameter change from crude extracts to purified compounds resolves the selectivity issue while preserving the economical and natural attributes.
3Adaptability or versatility
If crude extracts from natural plants are screened, then diverse compounds are obtained, but time-consuming screening process occurs
Solution Approach 1:
The patent directly extracts and isolates the active flavonoid compounds (protoapigenone, 5′,6′-dihydro-6′-methoxyprotoapigenone, protoapigenin) from Thelypteris torresiana through targeted extraction and chromatography, bypassing the need for extensive screening of multiple crude extracts. This approach resolves the contradiction by obtaining diverse, active compounds efficiently without time-consuming screening.
Solution Approach 2:
The patent performs preliminary extraction and isolation of flavonoid compounds from the plant material before conducting biological activity tests. This preliminary action resolves the contradiction by preparing purified compounds in advance, eliminating the need for time-consuming screening of crude extracts while maintaining access to diverse, bioactive compounds.
