• PubMed Abstract: 
  

  The therapeutic effects of Δ ⁹ -tetrahydrocannabinol (Δ ⁹ -THC) can be enhanced by modifications of the pentyl moiety at C-3. The engineering of Cannabis sativa olivetolic acid cyclase and tetraketide synthase with F24I and L190G substitutions, respectively, in the biosynthesis of Δ ⁹ -THC serves as a platform for the generation of resorcylic acids up to 6-undecylresorcylic acid. These results provide insights into the development of THC analogs with chemically distinct acyl moieties at C-3.
