(-)-Nebivolol-[d4] Hydrochloride, is the labelled analogue of Nebivolol. Nebivolol, a highly selective β1-adrenergic receptor inhibitor, has vasodilatory effect so that could be effective against hypertension. It was just withdrawed a Phase II/III trial for Hypertension in patients with chronic obstructive pulmonary disease.

(−)-Neplanocin A potently and irreversibly inactivates SAH hydrolase (Ki = 8.39 nM). It has antitumor activity against mouse leukemia L1210 cells and broad-spectrum antiviral activity. Neplanocin A is more potent against vesicular stomatitis than the reversible SAH hydrolase inhibitor 3-deazaneplanocin (ID50 = 0.07 and 0.3 μg/ml, respectively).
