We designed a series of specifically deuterated benzopyran analogues as new COX-2 inhibitors with the aim of improving their pharmacokinetic properties. As expected, the deuterated compounds retained potency and selectivity for COX-2. The new molecules possess improved pharmacokinetic profiles in rats compared to their nondeuterated congeners. Most importantly, the new compounds showed pharmacodynamic efficacy in several murine models of inflammation and pain. The benzopyran derivatives were separated into their enantiomers, and the activity was found to reside with the S-isomers. To streamline the synthesis of the desired S-isomers, an organocatalytic asymmetric domino oxa-Michael/aldol condensation reaction was developed for their preparation.

In this manuscript, we report the discovery of the substituted 2-trifluoromethyl-2H-benzopyran-3-carboxylic acids as a novel series of potent and selective cyclooxygenase-2 (COX-2) inhibitors. We provide the structure-activity relationships, optimization of design, testing criteria, and human half-life data. The challenge of a surprisingly long half-life (t 1/2 = 360 h) of the first clinical candidate 1 and human t 1/2 had been difficult to predict based on allometric scaling for this class of highly ppb compounds. We used a microdose strategy which led to the discovery of clinical agents 18c-(S), 29b-(S), and 34b-(S) with human half-life of 57, 13, and 11 h.

The integrin αvβ3, vitronectin receptor, is expressed in a number of cell types and has been shown to mediate adhesion of osteoclasts to bone matrix, vascular smooth muscle cell migration, and angiogenesis. We recently disclosed the

Baclofen (β-p-chlorophenyl GABA) is one of the selective agonists for the bicuculline-insensitive GABA(B) receptors. In the search for new compounds that bind to GABA(B) receptors it is very important to clarify the structural requirements. We report the syntheses of and binding studies on various 3- heteroaromatic (benzo[b]furan and benzo[b]thiophen)aminobutyric acids. The 4- amino-3-(7-methyl-benzo[b]furan-2-yl)butanoic acid 8g is a potent and specific ligand for GABA(B) receptors, with an IC50 value of 5.4 μM in the displacement of [3H]GABA.
