Synthesis and nematicidal activities of 1,2,3-benzotriazin-4-one containing 4,5-dihydrothiazole-2-thiol derivatives against Meloidogyne incognita

A series of novel 1,2,3-benzotriazin-4-one derivatives containing 4,5-dihydrothiazole-2-thiol were synthesized and characterized by 1H NMR, 13C NMR, 19F NMR and HRMS. The bioassay results showed that compounds 3-(3-((4,5-dihydrothiazol-2-yl)thio)propyl)-7-methoxybenzo[d][1–3]triazin-4(3H)-one, 3-(3-((4,5-dihydrothiazol-2-yl)thio)propyl)-6-nitrobenzo[d][1–3]triazin-4(3H)-one, 7-chloro-3-(3-((4,5-dihydrothiazol-2-yl)thio)propyl)benzo[d][1–3]triazin-4(3H)-one exhibited good control efficacy against the cucumber root-knot nematode disease caused by Meloidogyne incognita at the concentration of 10.0 mg L?1 in vivo. Compound 7-chloro-3-(3-((4,5-dihydrothiazol-2-yl)thio)propyl)benzo[d][1–3]triazin-4(3H)-one showed excellent nematicidal activity with inhibition 68.3% at a concentration of 1.0 mg L?1. It suggested that the structure of 1,2,3-benzotriazin-4-one containing 4,5-dihydro-thiazole-2-thiol could be optimized further.

Synthesis and nematicidal evaluation of 1,2,3-benzotriazin-4-one derivatives containing piperazine as linker against Meloidogyne incognita

To explore new skeleton with nematicidal activity, a series of novel 1,2,3-benzotriazin-4-one derivatives containing piperazine as linker were synthesized and varied fragments were also introduced to increase structure diversity of the new skeleton. Their inhibitory activities in vivo were evaluated against Meloidogyne incognita. The newly prepared compounds A6, A8, A21, A28 and A38 exhibited more than 50% inhibition at the concentration of 20 mg/L. Especially compound A6 displayed 71.4% inhibition against Meloidogyne incognita at the concentration of 20 mg/L. The nematicidal activities varied significantly depending on the types and positions of the substituents, which provided guidance for further structure modification.

Trash to treasure: Eco-friendly and practical synthesis of amides by nitriles hydrolysis in WepPA

The hydration of nitriles to amides in a water extract of pomelo peel ash (WEPPA) was realized with moderate to excellent yields without using external transition metals, bases or organic solvents. This reaction features a broad substrate scope, wide functional group tolerance, prominent chemoselectivity, and good reusability. Notably, a magnification experiment in this bio-based solvent at 100 mmol further demonstrated its practicability.

Design, synthesis and biological activities of 2,3-dihydroquinazolin-4(1H)-one derivatives as TRPM2 inhibitors

Transient receptor potential melastatin 2 (TRPM2), a Ca2+-permeable cationic channel, plays critical roles in insulin release, cytokine production, body temperature regulation and cell death as a reactive oxygen species (ROS) and temperature sensor. However, few TRPM2 inhibitors have been reported, especially TRP-subtype selective inhibitors, which hampers the investigation and validation of TRPM2 as a drug target. To discover novel TRPM2 inhibitors, 3D similarity-based virtual screening method was employed, by which 2,3-dihydroquinazolin-4(1H)-one derivative H1 was identified as a TRPM2 inhibitor. A series of novel 2,3-dihydroquinazolin-4(1H)-one derivatives were subsequently synthesized and characterized. Their inhibitory activities against the TRPM2 channel were evaluated by calcium imaging and electrophysiology approaches. Some of the compounds exhibited significant inhibitory activity, especially D9 which showed an IC50 of 3.7 μM against TRPM2 and did not affect the TRPM8 channel. The summarized structure-activity relationship (SAR) provides valuable insights for further development of specific TRPM2 targeted inhibitors.

Design, Synthesis, and Potency of Pyruvate Dehydrogenase Complex E1 Inhibitors against Cyanobacteria

Safe and effective algaecides are needed to control agriculturally and environmentally significant algal species. Four series (6, 10, 17, and 21) of 29 novel 4-aminopyrimidine derivatives were rationally designed and synthesized. A part of 10, 17, and 21 displayed potent inhibition of Escherichia coli pyruvate dehydrogenase complex E1 (E. coli PDHc-E1) (IC50 = 2.12-18.06 μM) and good inhibition of Synechocystis sp. PCC 6803 (EC50 = 0.7-7.1 μM) and Microcystis sp. FACH 905 (EC50 = 3.7-7.6 μM). The algaecidal activity of these compounds positively correlated with their inhibition of E. coli PDHc-E1. In particular, 21l and 10b exhibited potent algaecidal activity against PCC 6803 (EC50 = 0.7 and 0.8 μM, respectively), values that were 2-fold increased compared to that of copper sulfate (EC50 = 1.8 μM), and showed the best inhibition of cyanobacterium PDHc-E1 (IC50 = 5.10 and 6.06 μM, respectively). 17h and 21e, the best inhibitors of E. coli PDHc-E1, were studied by molecular docking, site-directed mutagenesis, and enzymatic assays. These results revealed that the improved inhibition of novel inhibitors compared with that of the lead compound I was due to the formation of a new hydrogen bond with Leu264 at the active site of E. coli PDHc-E1. The results proved the great potential to obtain effective algaecides via the rational design of PDHc-E1 inhibitors. [Figure Presented]

Identification and Development of 2,3-Dihydropyrrolo[1,2-a]quinazolin-5(1H)-one Inhibitors Targeting Bromodomains within the Switch/Sucrose Nonfermenting Complex

Bromodomain containing proteins PB1, SMARCA4, and SMARCA2 are important components of SWI/SNF chromatin remodeling complexes. We identified bromodomain inhibitors that target these proteins and display unusual binding modes involving water displacement from the KAc binding site. The best compound binds the fifth bromodomain of PB1 with a KD of 124 nM, SMARCA2B and SMARCA4 with KD values of 262 and 417 nM, respectively, and displays excellent selectivity over bromodomains other than PB1, SMARCA2, and SMARCA4.
