Phenolic Derivatives Modulating Androgen Receptors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current androgen receptor modulators are inadequate in effectively addressing hormone-dependent cancers and other androgen-related disorders, such as prostate cancer and breast cancer, due to limitations in modulating androgen receptor activity.
Innovation Solution
Development of novel phenolic derivatives with specific structural formulas that act as powerful androgen receptor modulators, capable of partial or total antagonist or agonist activities, which can be used to treat hormone-dependent cancers and androgen-related disorders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current androgen receptor modulators are used, then treatment of androgen-related disorders is provided, but the modulators are inadequate in effectively addressing hormone-dependent cancers and other androgen-related disorders
Solution Approach 1:
The patent modifies the chemical structure of androgen receptor modulators by changing parameters such as the introduction of fluorine atoms at specific positions (e.g., 7-fluoro, 6-fluoro), modification of the D-ring structure, and adjustment of substituent groups. These parameter changes in the molecular structure enhance the reliability of androgen receptor modulation while expanding the versatility to treat multiple conditions including prostate cancer, breast cancer, and other androgen-related disorders
2Reliability
If novel phenolic derivatives with specific structural formulas are developed, then powerful androgen receptor modulator activity is achieved, but the complexity of compound structure increases
Solution Approach 1:
The patent segments the steroid molecule into distinct rings (A, B, C, D rings) and independently optimizes each segment. The A-ring contains the phenolic hydroxyl group, the B-ring contains the 6-fluoro substitution, the C-ring maintains the keto group, and the D-ring is modified with various substituents. This segmentation allows systematic development of analogs with improved activity while managing structural complexity through modular design
Solution Approach 2:
The patent applies local quality modifications by introducing specific functional groups at precise locations in the molecule. For example, fluorine atoms are placed at specific positions (6-fluoro, 7-fluoro), hydroxyl groups are positioned at the A-ring (phenolic position), and various substituents are added to the D-ring. These localized modifications enhance androgen receptor modulator activity without requiring complete restructuring of the entire molecule
