[A new flavone from stems of Garcinia bracteata and its anti-TMV activity].
Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2016A phytochemical investigation on the stems of Garcinia bracteata collected from Xishuangbanna resulted in the isolation of a new flavone. By analysis of the HRESIMS, IR, UV, 1D and 2D NMR spectra, the structure of the new compound was determined as 7-methoxy-4',6-dihydroxy-8-isobutyryl-flavone(1).

A series of flavonoid derivatives containing piperazine sulfonate were designed and synthesized. The results of antiviral experiments in vivo showed that some target compounds had good inhibitory effect on tobacco mosaic virus (TMV). The EC50 values of S15 and S19 curative activity were 174.5 and 110.4 μg/mL, respectively, which were better than 253.7 ...

Tobacco mosaic virus (TMV) is a major threat to crops, making the discovery of green biopesticides essential. Herein, we present two active ingredients derived from the medicinal plant Dendrobium findlayanum, findlayine A (1) and dendrofindline B (2), as promising precursor compounds for TMV inhibitors.

Abstract A series of 0,0-diethyl-α-(p-toluenesulphonureado) phosphonates have been synthesized by the Mannich-type reaction of p-toluenesulphonurea, (substituted) benzaldehydes and dialkyl phosphites with acetyl chloride as the solvent. The bioassay results showed that some of them possess good anti-TMV (Tobacco Mosaic Virus) activities and the ...

A new naphthaldehyde derivative has been isolated from Comastoma pulmonarium by using various chromatographic techniques, including silica gel, Sephadex LH-20, MCI-gel resin and RP-HPLC. This compounds was determined as 5-methoxy-2-methyl-7-(2-oxopropyl)naphthalene-1-carbaldehyde(1) by NMR, MS, IR and UV spectra.

Fourteen compounds, including three new isochromenes (1-3) and four new isoquinolines (4-7), were isolated from Streptomyces mirabilis YMZU50. The anti-tobacco mosaic virus (TMV) activities of compounds 1-8 and 13 were evaluated. Compound 6 exhibited the strongest inactivation and protective effects, with inhibition rates of 76.8 and 80.2 ...
