Disclosure Statement

I am not a medical expert; I am a researcher who wanted to help tackle the problem of antibiotic resistance. If medical professionals or drug developers find this data useful, I hope they use it to create safe, effective, and affordable treatments for those who need them most.

Overview

These molecules feature a central imidazole core with bis-dioxolane "wings," providing a high Fraction Csp3 (0.80) to facilitate evasion of the AcrAB-TolC efflux pump system in Gram-negative pathogens.

LAZ-1123 molecular structure

Markush Family (Formula I)

Markush structure showing chemical family

Core — (X) — (Y)

  • Core: 5-membered aromatic nitrogen heterocycle (Imidazole or Triazole)
  • X and Y: Independent 1,3-dioxolane rings
  • Substitution: At least one ring comprises R group where R is H, C1-C6 alkyl, or C1-C6 alkoxy

Technical Methodology

These leads were discovered and validated using open-source computational tools:

ChEMBL: Fragment retrieval and QS target data
BRICS: Fragment-based decomposition and recombination
RDKit: Molecular informatics and property calculation
Smina: Molecular docking and binding affinity
OpenBabel: Chemical format interconversion
Pandas & Google Colab: Data management and workflow

The "Troll Shield": Defensive Disclosure

To prevent this chemical space from being locked away by patent trolls, Nicholas Panek establishes comprehensive Prior Art for the Markush family defined above. This disclosure asserts that any future claim regarding 3D-globular (Fsp3 > 0.75) scaffolds for MetAP or Quorum Sensing inhibition based on this genus is anticipated by this document.

Key Technical Advantage

Efflux Evasion: The high Fraction Csp3 (0.80) creates a non-planar geometry that limits recognition and ejection by the AcrAB-TolC efflux pump system in Gram-negative pathogens.
