Adenosine is known to exert a wide range of pharmacological effects including hypotension. This effect of adenosine suggested that modified analogues of adenosine might provide useful antihypertensive agents. Thus, we prepared a series of novel N6-benzocycloalkyladenosines and studied their receptor binding and antihypertensive activity. The structure-activity relationship study shows that the adenosine analogues having the hydrophobic phenyl moiety one carbon away from the C6-nitrogen have modest affinity and selectivity for the A1 receptor, whereas those with the phenyl moiety two carbons away from the C6-nitrogen have excellent affinity and selectivity for the A1 receptor. Many of these analogues showed excellent antihypertensive activity with a wide range of effects on heart rate. There is no direct correlation between the receptor binding affinities and antihypertensive activity; however, it is more closely associated with A1 than A2 affinity. The bradycardic effect of these agonists seems to be due to the A1 affinity. From this set, compound 3 was further evaluated in secondary antihypertensive screens. It lowered the blood pressure dose dependently with effects lasting for over 20 h following administration of a 30 mg/kg dose. Compound 3 was also effective in lowering blood pressure in a renal hypertensive rat model. Thus, appropriately modified N6-substituted adenosines represent a novel class of antihypertensive agents.

Synthesis of Dopamine, Rotigotin, Ladostigil, Rasagiline Analogues 2-Amino-4,5,6-trimethoxyindane, 1-Amino-5,6,7-trimethoxyindane, and Their Sulfamide Derivatives
converted to the azide derivative via Mitsunobu reaction with diphenylphosphoryl azide; Pd-C catalyzed hydrogenation of the azide to the amine hydrochloride and then deprotonation of the amine hydrochloride with NaOH furnished the ladostigil and rasagiline analogue 1-aminoindane. These amines and BnOH were reacted with CSI to produce sulfamoyl carbamates, which were converted to sulfamides via Pd-C-catalyzed
