Recently I am researching about BACTERIAL LEAF-BLIGHT; ORYZAE PV. ORYZAE; ANTIBACTERIAL ACTIVITY; ANTIVIRAL ACTIVITY; MOLECULAR DOCKING; RESISTANCE GENES; DESIGN; ANTICANCER; HYBRIDS; CYTOTOXICITY, Saw an article supported by the National Key Research and Development Program of China [2017YFD0200506]; Science and Technology Project of Guizhou Province [20185781]. Published in ROYAL SOC CHEMISTRY in CAMBRIDGE ,Authors: Guo, T; Xia, ROJ; Chen, M; He, J; Su, SJ; Liu, LW; Li, XY; Xue, W. The CAS is 94-41-7. Through research, I have a further understanding and discovery of Chalcone. Safety of Chalcone
A series of novel chalcone derivatives containing a thiophene sulfonate group were designed and synthesized. The structures of all title compounds were determined by H-1-NMR, C-13-NMR and HRMS. Antibacterial bioassays indicated that, compound 2l demonstrated excellent antibacterial activities against Xanthomonas axonopodis pv. citri (Xac), with an EC50 value of 11.4 mu g mL(-1), which is significantly superior to those of bismerthiazol (BT) (51.6 mu g mL(-1)) and thiodiazole-copper (TC) (94.7 mu g mL(-1)). Meanwhile, the mechanism of action of compound 2l was confirmed by using scanning electron microscopy (SEM). In addition, compound 2e showed remarkable inactivation activity against Tobacco mosaic virus (TMV), with an EC50 value of 44.3 mu g mL(-1), which was superior to that of ningnanmycin (120.6 mu g mL(-1)). Microscale thermophoresis (MST) also showed that the binding of compounds 2e and 2h to Tobacco mosaic virus coat protein (TMV-CP) yielded K-d values of 0.270 and 0.301 mu mol L-1, which are better than that of ningnanmycin (0.596 mu mol L-1). At the same time, molecular docking studies for 2e and 2h with TMV-CP (PDB code: ; 1EI7) showed that the compound was embedded well in the pocket between the two subunits of TMV-CP in each case. These results suggested that chalcone derivatives containing a thiophene sulfonate group may be considered as activators in the design of antibacterial and antiviral agents.
