Combined TRPC3 and TRPC6 blockade by selective small-molecule or genetic deletion inhibits pathological cardiac hypertrophy [PDF]

, 2014
Chronic neurohormonal and mechanical stresses are central fea-tures of heart disease. Increasing evidence supports a role forthe transient receptor potential canonical channels TRPC3 andTRPC6 in this pathophysiology.

Chiral versus achiral crystal structures of 4-benzyl-1H-pyrazole and its 3,5-diamino derivative

Acta Crystallographica Section E: Crystallographic Communications
The crystal structures of 4-benzyl-1H-pyrazole (C10H10N2, 1) and 3,5-diamino-4-benzyl-1H-pyrazole (C10H12N4, 2) were measured at 150 K. Although its different conformers and atropenantiomers easily interconvert in solution by annular tautomerism and/or ...
