1-{1H-pyrrolo[2,3-d]pyrimidin-4-yl}piperazine dihydrochloride is a compound used as a molecular building block.

Salusin-α is an endogenous bioactive peptide with hemodynamic and cell proliferation activities. Salusin-α can stimulate the proliferation of quiescent vascular smooth muscle cells (VSMCs) and fibroblasts, leading to a rapid and significant decrease in blood pressure and heart rate, but its effect is weaker than that of Salusin-β . Salusin-α has potential application value in cardiovascular disease research.

1H-Benzimidazole-6-carboxamide, N-[3-(aminocarbonyl)-4,5,6,7-tetrahydrobenzo[b]thien-2-yl]- may have antitumor activity.
