A series of 8-substituted quinolines were synthesized and tested against seizures induced by maximal electro shock (MES), pentylenetetrazole (scMet) and antihypertensive activities. Neurologic deficit was evaluated by the rotarod test. Among the newly synthesized derivatives, several compounds with a 2-hydroxypropyloxyquinoline moiety displayed excellent anticonvulsant and antihypertensive activities. Compound 20 (8-(3′-(4″-phenylpiperazino)-2′-hydroxypropyloxy)quinoline) was potent in both series as an anticonvulsive agent. 13 (8-(3′-piperazino)-2′-hydroxypropyloxyquinoline) and 14 (8-(3′-imidazolo)-2′-hydroxypropyloxyquinoline) showed very good anticonvulsant activities in the propanol series of compound, whereas in the ethane series, 1 (8-(2′-piperazino-ethanoxy)quinoline) and 2 (8-(2′-imidazolo-ethanoxy)quinoline) were the most active as anticonvulsive agents. Compounds 20 (8-(3′-(4″-phenylpiperazino)-2′-hydroxypropyloxy)quinoline), 13 (8-(3′-piperazino)-2′-hydroxypropyloxyquinoline) and 19 (8-(3′-(4″-ethylpiperazino)-2′-hydroxypropyloxy)quinoline) have shown excellent antihypertensive activity. They have significantly antagonized the pressor response elicited by adrenaline. These pharmacological results suggest that their anticonvulsant and antihypertensive effects may be correlated to the presence of β-blocking properties, and that those properties depend on the presence of aryloxypropanolamine.

Joining aryl 8-azabicyclo[3.2.1]oct-3-enes with aryloxyethanes and aryloxypropanes produces novel series of compounds 11 and 12 with potent 5-HT-T affinity and moderately potent 5-HT1A affinity. Moreover, several of these compounds possess functional 5-HT1A antagonism. Optimal compounds are, 4-indolyloxyethane 21, 4-indolyloxypropanes 25, and 27, which possess potent 5-HT-T affinity (5-HT-T K-i: 21: 1.2 nM, 25: 0.54 nM, 27: 0.38 nM) and good 5-HT1A affinity/antagonism (5-HT1A K-i, [S-35]GTPgammaS: E-max (%): 21: 111.1 nM, 0% 25: 173.2 nM, 0%; 27: 107 nM, 0%).
