PESTICIDE BIOCHEMISTRY AND PHYSIOLOGY 2020; 170:104695. [PMID: 32980058 DOI: 10.1016/j.pestbp.2020.104695] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/17/2020] [Revised: 08/19/2020] [Accepted: 08/19/2020] [Indexed: 06/11/2023]
Abstract
In this study, thirty 1,3,4-oxadiazole sulfone derivatives containing 3,4-dichloroisothiazolamide moiety were designed and synthesized, and their antibacterial activities were evaluated. Bioassay results showed that some compounds exhibited excellent antibacterial activities against Xanthomonas oryzae pv. oryzae (Xoo) and Xanthomonas oryzae pv. oryzicola (Xoc) in vitro and in vivo. Notably, the EC50 values of compounds 2 and 3 against Xoo were 0.79 and 0.85 μg/mL, respectively, which were superior to those of the control agents isotianil, bismerthiazol, and thiodiazole copper. In addition, in vivo antibacterial activities revealed that the compound 2 at 50 μg/mL possessed protective and curative activities of 43.99% and 41.06% against Xoo, respectively, which were better than positive controls. Furthermore, the preliminary mechanism study disclosed that compound 2 exhibited effective antibacterial activity against Xoo by inhibiting the formation of extracellular polysaccharides from Xoo, increasing cell permeability, and changing the shape of cells. This study suggested that 1,3,4-oxadiazole sulfone derivatives containing 3,4-dichloroisothiazolamide moiety displayed excellent antibacterial activity and could be further explored and developed as commercial pesticides.

Abstract
This study aimed to synthesize some new sulfone derivatives containing a 1,3,4-oxadiazole moiety and investigate their in vitro antibacterial activities against Xanthomonas oryzae pv. oryzae ( Xoo) and Xanthomonas axonopodis pv. citri ( Xac), the pathogens of rice bacterial leaf blight and citrus canker, respectively, by performing turbidimeter tests. Antibacterial bioassay results showed that compound 6d revealed excellent bioactivities against Xoo and Xac, with the 50% effective concentration (EC50) values of 0.17 and 1.98 μg/mL, respectively, compared with thiodiazole copper (121.82 and 77.04 μg/mL, respectively) and bismerthiazol (92.61 and 58.21 μg/mL, respectively). Meanwhile, greenhouse-condition trials indicated that, compared with thiodiazole copper and bismerthiazol, compound 6d more effectively reduced rice bacterial leaf blight.

Abstract
We report a true MCR involving the reaction of N-(prop-2-ynyl)quinoxalin-2-amine derivatives with 2-iodoanilines and tosyl azide in the presence of 10 mol% of CuI and Et3N in DMSO to afford the pre-designed hybrid molecules containing quinoxaline framework linked with a benzimidazole nucleus. The MCR proceeds in the absence of any ligand and/or lateral addition of the catalyst/base affording products within 30 min in good yields, some of which showed encouraging apoptosis inducing properties in zebrafish.

Abstract
A series of novel unsaturated five-membered benzo-heterocyclic amine derivatives were synthesized and assayed to determine their in vitro broad-spectrum antiviral activities. The biological results showed that most of our synthesized compounds exhibited potent broad-spectrum antiviral activity. Notably, compounds 3f (IC50=3.21-5.06 μM) and 3g (IC50=0.71-34.87 μM) showed potent activity towards both RNA viruses (influenza A, HCV and Cox B3 virus) and a DNA virus (HBV) at low micromolar concentrations. An SAR study showed that electron-withdrawing substituents located on the aromatic or heteroaromatic ring favored antiviral activity towards RNA viruses.

Abstract
A novel complex of
cadmium (II) picrate (pic) with V-shaped ligand
bis(N-allylbenzimidazol-2-ylmethyl)benzylamine
(babb), with composition
[Cd(babb)2](pic)2, was
synthesized and characterized by elemental
analyses and electrical conductivity, IR, and
UV/visible spectra. The crystal structure of the
complex has been determined by the
single-crystal X-ray diffraction. In the
complex, the coordination sphere around Cd (II)
is distorted octahedral, six nitrogen atoms
involved in coordination afforded by two
tridentate ligand babb. Moreover, The
DNA-binding properties of the ligand babb and Cd
(II) complex were investigated by
spectrophotometric methods and viscosity
measurements, and the results suggest that they
bind to DNA via an intercalation binding mode,
and the Cd (II) complex shows higher affinity
than the ligand.

Both sulfonyl O atoms lie to one side of the S-bound benzene ring, and the carbonyl and furan O atoms are syn to each other. Supra-molecular arrays parallel to (101) sustained by C-H⋯O contacts feature in the crystal packing.

The overall conformation of the title molecule, C14H11BrO3S, is L-shaped, as seen in the value of the dihedral angle formed between the terminal benzene rings of 75.44 (13)°. The presence of C—H⋯O interactions leads to the formation of linear supramolecular chains along the a-axis direction in the crystal structure. These are connected into supramolecular arrays in the ab plane via C—H⋯π contacts.

Abstract
Novel bis(benzimidazol-2-yl)amines were synthesized using two methods and studied for antitrichinellosis activity. DFT calculations were performed in order to determine the geometry of molecules. All derivatives of 2-aminobenzimidazole exhibited higher activity in vitro against Trichinella spiralis larvae in regard to the activity of albendazole, moreover compounds 4f-i manifested antitrichinellosis effect, which surpassed five times the activity of albendazole. The in vivo screening of intestinal phase of the T. spiralis revealed 100% effectiveness of compounds 4g-i at oral dosages of 50 and 100mg/kgmw, while albendazole possesses 100% efficacy only at a dose of 100mg/kgmw.

Abstract
Piperazine derivatives of 5(6)-substituted-(1H-benzimidazol-2-ylthio)acetic acids were synthesized by using two methods and studied for antihelminthic activity. The antiparasitic screening showed that compounds 18-24 exhibited higher activity against Trichinella spiralis in vitro in comparison to methyl 5-(propylthio)-1H-benzimidazol-2-yl-carbamate (albendazole). Most active were compounds 2-({2-[4-(4-chlorophenyl)piperazin-1-yl]-2-oxoethyl}thio)-1H-benzimidazole 21 and 2-{[2-oxo-2-(4-benzhydrylpiperazin-1-yl)ethyl]thio}-5(6)-methyl-1(H)-benzimidazole 19 as well as 2-({2-[4-(4-chlorophenyl)piperazin-1-yl]-2-oxoethyl}thio)-5(6)-methyl-1(H)-benzimidazole 23 with efficacy of 96.0%, 98.4% and 100%, respectively. The tested derivatives 15-19 and 20-23 were less active against Syphacia obvelata in vivo than albendazole and exhibited the same efficacy as piperazine, but in twice lower concentration.Compounds 2-({2-[4-(4-chlorophenyl)piperazin-1-yl]-2-oxoethyl}thio)-1H-benzimidazole 21, 1,4-bis[(5(6)-methyl-1(H)-benzimidazol-2-ylthio)acetyl]piperazine 17 and 2-({2-[4-(4-chlorophenyl)piperazin-1-yl]-2-oxoethyl}thio)-5(6)-methyl-1(H)-benzimidazole 23 had higher efficacies of 73%, 76%, and 77%, respectively.

Abstract
Three series of H(4) receptor ligands, derived from indoly-2-yl-(4-methyl-piperazin-1-yl)-methanones, have been synthesized and their structure-activity relationships evaluated for activity at the H(4) receptor in competitive binding and functional assays. In all cases, substitution of small lipophilic groups in the 4 and 5-positions led to increased activity in a [(3)H]histamine radiolabeled ligand competitive binding assay. In vitro metabolism and initial pharmacokinetic studies were performed on selected compounds leading to the identification of indole 8 and benzimidazole 40 as potent H(4) antagonists with the potential for further development. In addition, both 8 and 40 demonstrated efficacy in in vitro mast cell and eosinophil chemotaxis assays.
