Antisense Molecules Targeting Staphylococcus aureus Ribosomal Proteins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for Staphylococcus aureus infections, particularly methicillin-resistant Staphylococcus aureus (MRSA), are inadequate in effectively inhibiting bacterial growth and do not provide sufficient therapeutic options for targeting ribosomal proteins.
Innovation Solution
Development of antisense molecules that target Staphylococcus aureus ribosomal proteins, comprising natural and non-natural nucleic acid polymers, which hybridize to specific coding regions, are used to inhibit bacterial growth by administering them topically or systemically, often in conjunction with cell-penetrating peptides for enhanced delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current treatments for Staphylococcus aureus infections are used, then existing therapeutic options are available, but they are inadequate in effectively inhibiting bacterial growth particularly MRSA
Solution Approach 1:
The patent changes the molecular target parameter by designing antisense molecules that specifically target ribosomal protein coding regions of S. aureus, rather than using conventional antibiotics. This parameter change enables effective inhibition of bacterial growth including MRSA strains that are resistant to traditional antibiotics
Solution Approach 2:
The patent employs composite molecular structures combining antisense oligonucleotides with cell-penetrating peptides to create a dual-function therapeutic agent. This composite approach enables both specific targeting of ribosomal proteins and effective delivery into bacterial cells, providing a versatile therapeutic option for treating S. aureus infections
2Reliability
If antisense molecules are designed to target ribosomal proteins, then specific inhibition of bacterial growth is achieved, but delivery into bacterial cells becomes challenging
Solution Approach 1:
The patent merges two functional components: antisense molecules for specific ribosomal protein targeting and cell-penetrating peptides for efficient cellular delivery. This combination resolves the contradiction by maintaining high targeting specificity while dramatically improving delivery efficiency into bacterial cells
Solution Approach 2:
The cell-penetrating peptide acts as an intermediary that facilitates the entry of antisense molecules into bacterial cells. This mediator overcomes the cell membrane barrier, enabling the antisense molecule to reach its target ribosomal protein coding region inside the cell
