The present invention relates to substituted 2-(3-phenylureido)benzamide derivatives of the general formula (I), wherein R1 is hydrogen, amino group, (C1 to C5)alkyl, (C2 to C5)alkenyl or (C2 to C5)alkynyl, optionally substituted with hydroxy or amino group, R2 is hydrogen, halogen, methoxy group or halogenated methoxy group and R3 and R4 are selected from the group consisting of hydrogen, halogen, methoxy group or trifluoromethoxy group. The compounds of general formula (I) inhibit one of the key plant enzymes cytokinin oxidase/dehydrogenase (CKX). The invention further relates to the use of these compounds in agriculture as biostimulators of plant growth, development and yield, and to increase their resistance to stress and to delay the senescence of plants. The present invention further relates to preparations for the treatment of plants containing these derivatives.
本发明涉及通式(I)的取代2-(3-苯基脲基)苯甲酰衍生物,其中R1为氢、氨基、(C1至C5)烷基、(C2至C5)烯基或(C2至C5)炔基,可选地取代为羟基或氨基,R2为氢、卤素、甲氧基或卤代甲氧基,R3和R4从氢、卤素、甲氧基或三氟甲氧基组成的群体中选择。通式(I)的化合物抑制植物酶细胞分裂素氧化酶/脱氢酶(CKX)之一。本发明还涉及将这些化合物用作农业中植物生长、发育和产量的生物刺激剂,以增强它们对压力的抵抗力并延缓植物的衰老。本发明还涉及含有这些衍生物的植物治疗制剂。
