NOVEL FORM OF SULFENTRAZONE, PROCESS FOR ITS PREPARATION AND USE THEREOF

The invention describes a new crystalline form of sulfentrazone and its preparation process. The invention also describes the analyses of the crystal through various analytical methods and the use of the crystal to prepare stable agrochemical formulation. The novel crystal form is particularly suitable for use in herbicidal compositions and in the control of unwanted plant growth.

Design and synthesis of 1-(benzothiazol-5-yl)-1H-1,2,4-triazol-5-ones as protoporphyrinogen oxidase inhibitors

Protoporphyrinogen oxidase (PPO, E.C. 1.3.3.4) is the action target for several structurally diverse herbicides. A series of novel 4-(difluoromethyl)-1- (6-halo-2-substituted-benzothiazol-5-yl)-3-methyl-1H-1,2,4-triazol-5(4H)-ones 2a-z were designed and synthesized via the ring-closure of two ortho-substituents. The in vitro bioassay results indicated that the 26 newly synthesized compounds exhibited good PPO inhibition effects with Ki values ranging from 0.06 to 17.79 μM. Compound 2e, ethyl 2-{[5-(4- (difluoromethyl)-3-methyl-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl) -6-fluorobenzo-thiazol-2-yl]thio}acetate, was the most potent inhibitor with Ki value of 0.06 μM against mtPPO, comparable to (Ki = 0.03 μM) sulfentrazone. Further green house assays showed that compound 2f (Ki = 0.24 μM, mtPPO), ethyl 2-{[5-(4-(difluoromethyl)-3-methyl-5- oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl)-6-fluorobenzothiazol-2-yl]thio} propanoate, showed the most promising post-emergence herbicidal activity with broad spectrum even at concentrations as low as 37.5 g ai/ha. Soybean exhibited tolerance to compound 2f at the dosages of 150 g ai/ha, whereas they are susceptible to sulfentrazone even at 75 g ai/ha. Thus, compound 2f might be a potential candidate as a new herbicide for soybean fields.

Synthesis and biological activity of novel phenyltriazolinone derivatives

Phenyltriazolinones are one of the most important classes of herbicides targeting the protoporphyrinogen oxidase enzyme. A series of triazolinone derivatives containing a strobilurin pharmacophore were designed and synthesized with the aim of discovering new phenyltriazolinone analogues with high activity. The herbicidal activity of the synthesized compounds was assayed and some of the test compounds displayed moderate herbicidal activity at 150 g ai/ha.
