Yang, Pei-Song published the artcileTwo new 2-arylbenzofurans from the stems of Nicotiana tabacum and their bioactivities, SDS of cas: 56317-21-6, the publication is Heterocycles (2016), 92(8), 1462-1467, database is CAplus.
Two new 2-arylbenzofurans, 4-(7-methoxy-3,5-dimethyl-benzofuran-2-yl)phenol (1), 4-(6-methoxy-3,5-dimethylbenzofuran-2-yl)-phenol (2), together with two known 2-arylbenzofurans (3 and 4) were isolated from the stems of Nicotiana tabacum. Their structures were determined by means of HRESIMS and extensive 1D and 2D NMR spectroscopic studies. Compounds 1-4 were tested for their anti-TMV and cytotoxicity activities. The results showed that compound 2 exhibited high anti-TMV activities with inhibition rates of 36.4% at the concentration of 20 μM. This rate is higher than that of pos. control. Compounds 1-4 showed moderate-to-weak cytotoxicities against some tested human tumor cell lines with IC50 values in the range of 2.2-8.4 μM.
