Synthesis and anti-TMV activity of novel N-(pyrimidin-5-yl)-N′-phenylureas

Chinese Chemical Letters, 2011
Abstract In order to find novel leading structures of pesticide, a series of N-(pyrimidin-5-yl)-N′-phenylureas (4a–4h) were designed and synthesized from 4-chloro-2-diethylamino-6-methyl-5-nitropyrimidine 1 via substitution, reduction and acylation procedures. Preliminary bioassay showed that all the target compounds processing good anti-TMV (tobacco

Total synthesis of the proposed structure of Anti-TMV active tabasesquiterpene A

Tetrahedron, 2021
Abstract The proposed structure of Tabasesquiterpene A, an illudalane type of sesquiterpene has been synthesized in twelve steps from 2-methoxy-4-methylbenzaldehyde in 40% overall yield. Triflic acid mediated intramolecular Freidel-Crafts acylation allows to develop the critical indanone moiety, a key intermediate of this synthesis.

Anti-TMV activity and effects of three prieurianin-type limonoids from Munronia henryi

Pesticide Biochemistry and Physiology, 2022
Three prieurianin-type limonoids (1-3), including two new compounds (1 and 2) and one known compound (3) were isolated from Munronia henryi. These compounds were tested for their activities against tobacco mosaic virus (TMV) by the conventional half-leaf method and the outcomes were analyzed by western blotting and RT-PCR assays.

Preparation and anti‐TMV activity of guanidinylated chitosan hydrochloride

Journal of Applied Polymer Science, 2009
AbstractIn this study, guanidinylated chitosan hydrochloride (GCH) was synthesized and its structure was characterized by UV–vis and FTIR. The degree of substitution of guanidinylated chitosan was confirmed by elemental analysis. In vitro antiviral activity of guanidinium derivative on local infection and systemic infection of tobacco mosaic virus (TMV)
