Manley P, Zartman A, Paone D, Burgey C, Henze D, Della Penna K, et al.
Bioorg Med Chem Lett . 2011 Mar; 21(8):2359-64. PMID: 21420857
A novel series of decahydroquinoline CB2 agonists is described. Optimization of the amide substituent led to improvements in CB2/CB1 selectivity as well as physical properties. Two key compounds were examined...
