  1-Aryl-tetrahydroisoquinoline analogs as active anti-HIV agents in vitro

  摘要：

  A series of 1-aryl-6,7-dihydroxyl(methoxy)-1,2,3,4-tetrahydroisoquinolines (compounds 1-36) were synthesized via Pictet-Spengler cyclization. All the synthesized compounds were assayed for activities against HIV-1(IIIB) in C8166 cell cultures by MTT method for the first time. The results of the anti-HIV screening revealed that 6,7-dihydroxytetrahydroisoquinolines possessed higher selective index than 6,7-dimethoxyl analogs due to the significantly decreased cytotoxicities. Compounds 6, 24, and 36 showed potent anti-HIV activities with EC50 values of 8.2, 4.6, and 5.3 mu M respectively, and the cytotoxicities (CC50) of these three compounds were 784.3, 727.3, and 687.3 mu M, which resulted in SI values larger than 95, 159, and 130 respectively.

  A green, biomimetic, phosphate-mediated Pictet-Spengler reaction was used in the synthesis of three catecholic tetrahydroisoquinolines, 1, 2, and 12, present in the medicinal plant Portulaca oleracea, as well as their analogues 3-11, 13, and 14, with dopamine hydrochloride and aldehydes as the substrates. AB-8 macroporous resin column chromatography was applied for purification of the products from the one-step high efficacy synthesis. It eliminated the difficulties in the isolation of catecholic tetrahydroisoquinolines from the aqueous reaction system and unreacted dopamine hydrochloride. Activity screening in CHO-K1/G alpha 15 cell models consistently expressing alpha(1B)-, beta(1)-, or beta(2)-adrenergic receptors indicated that 12 and 2, compounds that are present in P. oleracea, possessed the most potent beta(2)-adrenergic receptor agonist activity and 2 was a selective beta(2)-adrenergic receptor agonist at the concentration of 100 mu M. Both 12 and 2 exhibited dose-dependent bronchodilator effects on the histamine-induced contraction of isolated guinea-pig tracheal smooth muscle, with EC50 values of 0.8 and 2.8 mu M, respectively. These findings explain the scientific rationale of P. oleracea use as an antiasthmatic herb in folk medicine and provide the basis for the discovery of novel antiasthma drugs.
