Abstract
Abstract A series of novel quinazoline derivatives bearing sulfonamide moiety was designed and synthesized, and their structure were characterized by 1H NMR, 13C NMR, and HRMS techniques. Among them, the structure of compound E1 was further confirmed through X-ray single-crystal diffraction analyses. Their anti-Tobacco mosaic virus (TMV) activities were evaluated through half-leaf method. The bioassay results showed that E8 and E19 possess excellent inhibitory activity towards TMV. The EC50 of curative activities, protective activities, and inactivating activities of E8 and E19 are 132.1, 152.8, 57.4 mg/L and 278.0, 165.3, 94.5 mg/L, respectively, which are far superior than Ribavirin (318.2, 201.5, 128.6 mg/L, respectively).
期刊介绍：
Heterocyclic Communications (HC) is a bimonthly, peer-reviewed journal publishing preliminary communications, research articles, and reviews on significant developments in all phases of heterocyclic chemistry, including general synthesis, natural products, computational analysis, considerable biological activity and inorganic ring systems. Clear presentation of experimental and computational data is strongly emphasized. Heterocyclic chemistry is a rapidly growing field. By some estimates original research papers in heterocyclic chemistry have increased to more than 60% of the current organic chemistry literature published. This explosive growth is even greater when considering heterocyclic research published in materials science, physical, biophysical, analytical, bioorganic, pharmaceutical, medicinal and natural products journals. There is a need, therefore, for a journal dedicated explicitly to heterocyclic chemistry and the properties of heterocyclic compounds.
