Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compounds are developed to activate Tie-2 receptor, then vascular stability is improved, but solubility and stability of the compounds may deteriorate
Solution Approach 1:
The patent modifies chemical parameters of the compound molecules, specifically adjusting the R1 substituent groups (hydrogen, acyl, alkoxycarbonyl, amidine, or amide groups) and core structural parameters (A, B, C, D, E moieties) to optimize the balance between Tie-2 activation potency and aqueous solubility. This allows the compounds to maintain vascular stability while improving solubility for effective delivery.
2Reliability
If compounds are developed to activate Tie-2 receptor, then vascular stability is improved, but stability and shelf life of the compounds may deteriorate
Solution Approach 1:
The patent optimizes chemical stability parameters by selecting specific stable substituent groups (R1 as hydrogen, acyl, alkoxycarbonyl, amidine, or amide) and core structures that resist degradation. This ensures the compounds maintain both their vascular stability efficacy and sufficient shelf life for pharmaceutical use.
3Reliability
If dosages are reduced for effective treatment, then therapeutic outcomes are improved, but the required compound concentration may worsen
Solution Approach 1:
The patent enhances the specific activity and potency of the compounds by optimizing the Tie-2 activating moieties and substituent patterns. This allows lower dosages to achieve effective therapeutic outcomes, as the highly active compounds can produce the desired vascular stability effect at lower concentrations.
