Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional anticancer agents are used, then cancer treatment is provided, but the agents lack potency and tolerability
Solution Approach 1:
The patent modifies the chemical structure of pyrimido[4,5-d]pyrimidine-2,4,7-trione core by changing substituent parameters at specific positions (R1-R6 groups) to optimize both potency and tolerability. This systematic parameter variation allows tuning of pharmacological properties to achieve better therapeutic window.
Solution Approach 2:
The invention creates composite molecular structures by combining the pyrimido[4,5-d]pyrimidine-2,4,7-trione scaffold with various aromatic and heteroaromatic substituent systems. This composite approach integrates multiple functional groups to achieve synergistic effects that improve both anticancer activity and tolerability profile.
2Reliability
If novel compounds with improved pharmacological activities are developed, then potency and tolerability are enhanced, but development time and complexity increase
Solution Approach 1:
The patent divides the molecular structure into a core pyrimido[4,5-d]pyrimidine-2,4,7-trione unit and separate substituent modules (R1-R6). This segmentation allows independent optimization of each module and facilitates systematic exploration of structure-activity relationships, reducing trial-and-error time in compound development.
Solution Approach 2:
The pyrimido[4,5-d]pyrimidine-2,4,7-trione core serves as a universal scaffold that can accommodate multiple types of substituents (aromatic, heteroaromatic, alkyl groups) to generate compounds with diverse pharmacological activities. This multi-functionality reduces the need to start from scratch for different therapeutic targets.
3Manufacturing precision
If comprehensive structure-activity relationship studies are conducted, then optimization of anticancer activity is achieved, but the complexity and cost of research increase
Solution Approach 1:
The patent focuses structure-activity relationship analysis on specific local regions of the molecule (positions R1-R6 substituents) rather than the entire molecule. This localized approach identifies key pharmacophore elements and their contributions to activity, simplifying the complexity of comprehensive SAR studies while maintaining precision in understanding structure-activity relationships.
