Biological Activity
tetrahydromagnolol is a major metabolite of magnolol and acts as a peripheral cb2 receptor agonist. tetrahydromagnolol also acts as an antagonist at gpr55 [1].cannabinoid (cb) receptors belong to the g protein-coupled receptor (gpcr) superfamily and are divided into cb1 and cb2. cb1 activation mediates analgesia, stimulation of appetite, and euphoria, among other effects. cb2 receptor activation results in analgesic and antiinflammatory effects. gpr55, a cb-related orphan receptor, is reported to interact with certain cbs [1].tetrahydromagnolol is a highly selective peripheral cb2 receptor agonist that is 19-fold more potent than magnolol with ec50 and ki values of 0.17 μm and 0.42 μm, respectively. magnolol is a bioactive compound isolated from the bark of magnolia officinalis that is used in asian traditional medicine for the treatment of anxiety, sleeping disorders, and allergic diseases. magnolol behaved as a partial agonist with selectivity for the cb2 subtype (ec50 = 3.28 μm; ki = 1.44 μm). in β-arrestin translocation assay, tetrahydromagnolol inhibited lpi-induced gpr55 activation with kb value of 13.3 μm [1].

Check Digit Verification of cas no
The CAS Registry Mumber 20601-85-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,6,0 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20601-85:
(7*2)+(6*0)+(5*6)+(4*0)+(3*1)+(2*8)+(1*5)=68
68 % 10 = 8
So 20601-85-8 is a valid CAS Registry Number.

Cytotoxic neolignans: An SAR study
Kong, Zwe-Ling,Tzeng, Shin-Cheng,Liu, Yeuk-Chuen
, p. 163 - 166 (2005)
The cytotoxic effects of different neolignans with the structure 1 were studied. The neolignans, magnolol 1 and honokiol 2 have been reported to inhibit the growth of several tumor cell lines in vitro and in vivo. The chemical structure of magnolol and honokiol consists of biphenyl skeleton with phenolic and allylic functionalities. Analogs of 1 and 2 containing different substitution have been studies for their effect on the growth of Hep-G2 and their structure-activity relationships were reported in this work.
Weak Coordination Promoted Regioselective Oxidative Coupling Reaction for 2,2′-Difunctional Biaryl Synthesis in Hexafluoro-2-propanol
Zhang, Chao,Rao, Yu
, p. 4456 - 4459 (2015/09/28)
An unprecedented weak coordination promoted dehydrogenative cross-coupling reaction has been developed by palladium catalysis, which provides a convenient access to a wide range of 2,2′-difunctional biaryls from easily accessible substrates. Both HFIP solvent and oxidants serve as the critical factors in this new reaction. A plausible mechanism involving Pd(II)/Pd(IV) is proposed. The reaction demonstrates excellent reactivity, broad functional-group tolerance and high yields.
