Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current kinase inhibitors (JAK3 and BTK inhibitors) are used, then kinase inhibitory activity is achieved, but severe side effects and instability occur
Solution Approach 1:
The patent modifies the chemical structure parameters of kinase inhibitors by introducing specific substituents (R1-R6) at defined positions in the molecular framework. This structural parameter optimization enhances compound stability while reducing off-target effects and improving therapeutic index
Solution Approach 2:
The invention creates composite molecular structures combining multiple functional groups (pyrazolyl, isooxazolyl, isothiazolyl, phenyl, benzothiazolyl rings with various substituents) into a unified kinase inhibitor framework, achieving synergistic effects that improve both stability and reduce side effects
2Reliability
If current kinase inhibitors are used, then kinase inhibitory activity is achieved, but therapeutic efficacy is insufficient
Solution Approach 1:
The patent optimizes local molecular properties by selecting specific substituents (R1-R6) at critical positions to enhance binding affinity to kinase active sites. The local chemical environment is tuned to improve interaction with target residues, thereby increasing therapeutic efficacy
Solution Approach 2:
The invention introduces dynamic adaptability in molecular binding through flexible substituent groups that can adjust their conformation to optimize interactions with the kinase target, enhancing binding affinity and therapeutic effect
