  Nitrogenated honokiol derivatives allosterically modulate GABAA receptors and act as strong partial agonists

  摘要：

  In traditional Asian medicinal systems, preparations of the root and stem bark of Magnolia species are widely used to treat anxiety and other nervous disturbances. The biphenyl-type neolignan honokiol together with its isomer magnolol are the main constituents of Magnolia bark extracts. We have previously identified a nitrogen-containing honokiol derivative (3-acetylamino-4'-O-methylhonokiol, AMH) as a high efficient modulator of GABA(A) receptors. Here we further elucidate the structure-activity relation of a series of nitrogenated biphenyl-neolignan derivatives by analysing allosteric modulation and agonistic effects on alpha(1)beta(2)gamma(2S) GABA(A) receptors. The strongest I-GABA enhancement was induced by compound 5 (3-acetamido-4'-ethoxy-3',5-dipropylbiphenyl-2-ol, E-max: 123.4 +/- 9.4% of IGABA-max) and 6 (5'-amino-2-ethoxy-3',5-dipropylbiphenyl-4'-ol, E-max: 117.7 +/- 13.5% of IGABA-max). Compound 5 displayed, however, a significantly higher potency (EC50 = 1.8 +/- 1.1 mu M) than compound 6 (EC50 = 20.4 +/- 4.3 mu M). Honokiol, AMH and four of the derivatives induced significant inward currents in the absence of GABA. Strong partial agonists were honokiol (inducing 78 +/- 6% of IGABA-max), AMH (63 +/- 6%), 5'-amino-2-O-methylhonokiol (1) (59 +/- 1%) and 2-methoxy-5'-nitro-3',5-dipropylbiphenyl-4'-ol (3) (52 +/- 1%). 3-N-Acetylamino-4'-ethoxy-3',5-dipropyl-biphenyl-4'-ol (5) and 3-amino-4'-ethoxy-3',5-dipropyl-biphenyl-4'-ol (7) were less efficacious but even more potent (5: EC50 = 6.9 +/- 1.0 mu M; 7: EC50 = 33.2 +/- 5.1 mu M) than the full agonist GABA.

  Biphenyl neolignans such as honokiol and magnolol, which are the major active constituents of the Asian medicinal plant Magnolia officinalis, are known to exert a multitude of pharmacological and biological activities. Among these, cytotoxic and tumor growth inhibitory activity against various tumour cell lines are well-documented. To further elucidate the cytotoxic effects of honokiol derivatives, derivatizations were performed using tetrahydrohonokiol as a scaffold. The derivatizations comprised the introduction of functional groups, e.g., nitro and amino groups, as well as alkylation. This way, 18 derivatives, of which 13 were previously undescribed compounds, were evaluated against CCRF-CEM leukemia cells, U251 glioblastoma and HCT-116 colon cancer cells. The results revealed no significant cytotoxic effects in any of the three tested cell lines at a test concentration of 10 µM.

  二联苯新木脂素类化合物如和厚朴酚和木兰脂素是亚洲药用植物厚朴的主要活性成分,它们具有多种药理和生物活性。其中,对各种肿瘤细胞系的细胞毒性和肿瘤生长抑制活性已有充分研究记录。 为进一步阐明和厚朴酚衍生物的细胞毒性作用,以四氢和厚朴酚为骨架进行了衍生化研究。衍生化包括引入硝基和氨基等官能团以及烷基化。 通过这种方式,对18个衍生物(其中13个为此前未描述的化合物)在CCRF-CEM白血病细胞、U251胶质母细胞瘤和HCT-116结肠癌细胞中进行了评估。结果显示,在10 μM的测试浓度下,这些化合物在三种测试细胞系中均未显示出显著的细胞毒性作用。
