    Abstract: RhlR modulators including agonist and antagonists which are useful for modulating QS phenotypes in Gram-negative bacteria. Certain compounds of general formula A-W-HG having various carbocyclic ad heterocyclic head groups (HG) and various tail groups (A), where -W- is -CO-NH-, -SO 2 -NH-, -CO-NH-CH 2 -, or -SO 2 -NH-CH 2 - are RhlR agonists or antagonists. The compounds are useful in methods of modulating quorum sensing in Gram-negative bacteria, particularly in Pseudomonas . Compositions including certain RhlR modulators are useful for decreasing the virulence of Gram-negative bacteria. Pharmaceutical compositions comprising certain RhlR modulators are useful for treatment of infections of Gram-negative bacteria.

    Abstract: Methods and systems for recovering dicyclopentadiene from pygas are provided. Methods can include heating pygas to generated heated pygas, recovering a C 5 fraction from the heated pygas, and dimerizing cyclopentadiene from the C 5 fraction to form dicyclopentadiene. Methods can further include recovering the C 5 fraction from the pygas in a depentanizer column. Other methods can include heating pygas including dicyclopentadiene to form cyclopentadiene and hydrogenating cyclopentadiene in the pygas to form cyclopentane.
