1Quantity of substance
If Darobactin A is produced using known producer strains, then the antibiotic can be obtained with selective activity against Gram-negative pathogens, but the production yield is poor and insufficient for structure engineering or semi-synthesis
Solution Approach 1:
The patent modifies the chemical structure of Darobactin A by changing parameters such as substituting hydrogen atoms with various groups (methyl, hydroxymethyl, halogen, hydroxy, methoxy) at specific positions (R1-R8) to create derivatives with improved production yield and enhanced biological activity against Gram-negative bacteria including ESKAPE pathogens
Solution Approach 2:
The invention creates composite molecular structures by combining the Darobactin A core scaffold with various substituent groups, resulting in derivative compounds that maintain the parent compound's selective Gram-negative activity while improving production characteristics and efficacy
