The present invention relates to novel renin inhibitors of general formula (1), novel intermediates involved in their synthesis, their pharmaceutically acceptable salts and pharmaceutical compositions containing them. The present invention also relates to a process of preparing compounds of general formula (1), their tautomeric forms, their pharmaceutically acceptable salts, pharmaceutical compositions containing them, and novel intermediates involved in their synthesis.
on an operationally simple catalytic method for the tungsten-catalyzed hydrogenation of quinolines through the use of the easily handled and self-contained precursor [WCl(η5-Cp)(CO)3]. This halfsandwichcomplex is indefinitely storable on the bench in simple screw-capped bottles or stoppered flasks and can, if required, be prepared on a multi-gram scale while the actual catalytic transformations were

is alkyl, alkoxy, haloalkoxy, a halogen atom, cyano, etc.; and R
3
is 7-oxo-7,8-dihydro-1,8-naphthyridinyl, 3-pyridyl, etc., or a salt thereof. The compound of the present invention has excellent antimicrobial activity against
Clostridium difficile
and is useful for the prevention or treatment of intestinal infection such as
Clostridium difficile
-associated diarrhea.
Aminopyrazine compounds as modulators of an adenosine receptor are provided. The compounds may find use as therapeutic agents for the treatment of diseases mediated through a G-protein-coupled receptor signaling pathway and may find particular use in oncology.
