Abstract A diversity-oriented synthesis of amide-containing thieno[2,3-d]pyrimidin-4(3H)-ones is reported. All compounds were tested for their influence on melanin synthesis in murine B16 cells. The azepine fragment in thieno[2,3-d]pyrimidin-4(3H)-one skeleton significantly increases the melanin content.

The present invention relates generally to azabicyclic containing pharmaceutical agents, and in particular, to azabicyclic metalloprotease inhibiting compounds. More particularly, the present invention provides a new class of azabicyclic MMP-3, MMP-8 and/or MMP-13 inhibiting compounds, which exhibit an increased potency and selectivity in relation to currently known MMP-13, MMP-8 and MMP-3 inhibitors.
