The invention relates to a compound of formula (1) ##STR00001## The invention further relates to Pd complexes comprising the compound according to the invention and to the use thereof in alkoxycarbonylation.

Disclosed herein are thiophene compounds of formulae (I), (I), (II), (II), (II), and (II), methods for making such compounds, and methods for making -R-substituted fused thiophene compounds by coupling such compounds.

The present invention relates to novel compounds and probes which have a common chemical structure necessary to obtain potent inhibitory activity against KLK4 and/or may be used for the detection of KLK4 peptides and their activity. It further relates to the use of these compounds and methods for inhibiting and/or detecting KLK4 activity in vitro and in vivo by making use of said probes or inhibitors. The compounds of the invention differ from prior art compounds at least in the presence of phenyl guanidine (instead of e.g. benzyl guanidine) and/or the presence of a heteroatom in the tail group, their combined presence unexpectedly leading to potent and selective KLK4 inhibitory activity.

The present invention provides for novel compounds of Formulas I and II and pharmaceutically acceptable salts and co-crystals thereof which have glucokinsae activator activity. The present invention further provides for pharmaceutical compositions comprising the same as well as methods of treating, preventing, delaying the time to onset or reducing the risk for the development or progression of a disease or condition for which one or more glucokinase activator is indicated, including Type 1 and 2 diabetes, impaired glucose tolerance, insulin resistance and hyperglycemia. The present invention also provides for processes of making the compounds of Formulas I and II, including salts and co-crystals thereof, and pharmaceutical compositions comprising the same.

Disclosed are compounds of Formulas (I), (II), (III), (IV), and (V):
