ROCK1 and ROCK2 are highly homologous isoforms. Accumulated studies indicate that they have distinct different functions, and the development of isoform selective ROCK inhibitors will pave new roads for the treatment of various diseases. In this work, a series of amide-chroman derivatives were synthesized and biologically evaluated in order to develop potent and isoform selective ROCK2 inhibitors. Remarkably, (S)-6-methoxy-chroman-3-carboxylic acid (4-pyridin-4-yl-phenyl)-amide ((S)-7c) possessed ROCK2 inhibitory activity with an IC50 value of 3 nM and 22.7-fold isoform selectivity (vs. ROCK1). Molecular docking indicated that hydrophobic interactions were the key element for the high potency and isoform selectivity of (S)-7c. The binding free energies predicted by MM/GBSA were in good agreement with the experimental bioactivities, and the analysis of individual energy terms suggested that residue Lys105 in ROCK1 or Lys121 in ROCK2 was the key residue for the isoform selectivity of (S)-7c.

Farnesoid X receptor (FXR), a nuclear receptor mainly distributed in liver and intestine, has been regarded as a potential target for the treatment of various metabolic diseases, cancer and infectious diseases related to liver. Starting from two previously identified chalcone-based FXR antagonists, we tried to increase the activity through the design and synthesis of a library containing chalcones, flavones and chromenes, based on substitution manipulation and conformation (ring closure) restriction strategy. Many chalcones and four chromenes were identified as microM potent FXR antagonists, among which chromene 11c significantly decreased the plasma and hepatic triglyceride level in KKay mice.

, p. 47 - 56 (2007/10/03)
A novel series of melatonin analogues based on the benzopyran nucleus is described. These compounds are prepared in several steps from substituted 2-hydroxybenzaldehydes. Some of these derivatives competitively inhibit 2-[125I]iodomelatonin binding to chicken brain and ovine pars tuberalis membranes although with reduced affinity compared with melatonin.
6- and 8-Hydroxy-3,4-dihydro-3-(dipropylamino)-2H-1-benzopyrans. Dopamine Agonists with Autoreceptor Selectivity

The dopamine agonist profiles of 3,4-duhydro-3-(3-dipropylamino)-2H-1-benzopyran-6- and 8-ol (4 and 5, respectively) were examined.Both 4 and 5 exhibited greater relative affinity for receptors labeled with the dopamine agonist ligand propylnorapomorphine than for those labeled with the dopamine antagonist ligand haloperidol.Both compounds attenuated the simulation of brain dopamine synthesis caused by γ-butyrolactone (GBL) and decreased the firing rate of substantia nigra dopamine neurons in rats.This profile of activity, together with the ability of the dopamine antagonist haloperidol to reverse the inhibition of dopamine neuronal firing, indicate that both compounds are brain dopamine agonists.
