Abstract
As a continuation of our efforts to develop new agrochemicals with typical architecture and efficient bioactivity from plant natural products, natural neolignan honokiol was used as a lead compound to prepare novel analogs bearing the core 2-aminobenzoxazole scaffold. Their insecticidal potency against two representative agricultural pests, Plutella xylostella Linnaeus and Mythimna separata (Walker), were evaluated in vivo. The pesticide bioassay results revealed that compounds 7″a, 9, 10d, and 10j exhibited prominent larvicidal activity against the larvae of P. xylostella (LC50 = 7.95, 11.85, 15.51, and 12.06 μg/mL, respectively), superior to the precursor honokiol (LC50 = 43.35 μg/mL) and two botanical insecticides, toosendanin (LC50 = 26.20 μg/mL) and rotenone (LC50 = 23.65 μg/mL). Compounds 7d, 10d, and 10j displayed a more pronounced nonchoice antifeedant effect (AFC50 = 9.48, 9.14, and 12.41 μg/mL, respectively) than honokiol (AFC50 = 54.81 μg/mL) on P. xylostella. Moreover, compounds 7b, 7″a, 9, 10d, 10f, and 10j showed better growth inhibitory activity against M. separata (LC50 = 0.36, 0.34, 0.28, 0.16, 0.26, and 0.11 mg/mL, respectively) than honokiol, toosendanin, and rotenone (LC50 = 1.48, 0.53, and 0.46 mg/mL, respectively). A potted plant assay under greenhouse conditions illustrated that compounds 10d and 10j continued to provide good control efficacy against P. xylostella and an apparent protective effect on plants. Further cytotoxicity assay revealed that the aforementioned potent compounds showed relatively moderate toxicity and a good safety profile for non-target mammalian cells. Overall, the current work provides valuable insight into the agrochemical innovation of honokiol-derived analogs for use as natural-inspired pesticides in agricultural pest management.

Abstract
This work deals with the synthesis and evaluation of fungicidal activity of benzimidazole derivatives, which are structural analogues of commercial anti-tubulin fungicides. A number of N-acyl and N-thioacyl derivatives of 2-amino-1H-benzo[d]imidazole were prepared, and their fungicidal activity against 13 strains of phytopathogenic fungi was studied. The most active compounds against the majority of the studied strains were 3a, 4l, and 4o, and the EC50 values of these compounds were in the range 2.5-20 μg/mL. Compound 3a showed the highest activity against the P. infestans strain, the growth of which is not suppressed by carbendazim. The formation of ligand-receptor complexes of various tautomeric forms of the studied benzimidazoles with homologous models of β-tubulins of B. cinerea, F. oxysporum, and P. infestans was modeled. Induced fit docking has been used for the simulation. The obtained data suggest the possibility of binding of benzimidazole fungicides to β-tubulin in the ″nocodazole cavity″ in the tautomeric form bearing a double exocyclic C═N bond. The importance of the formation of hydrogen bonds of benzimidazoles with the amino acid residue Val236 along with the Glu198 residue is also revealed in the present study.

Synthesis of N-methylpyridine-chlorofuranformamide analogs as novel OPG up-regulators and inhibitors of RANKL-induced osteoclastogenesis. Bioorg Chem 2021; 116:105361. [PMID: 34562672 DOI: 10.1016/j.bioorg.2021.105361] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2021] [Revised: 09/11/2021] [Accepted: 09/13/2021] [Indexed: 11/26/2022]
Abstract
The OPG/RANKL/RANK pathway is a promising target for the design of therapeutic agents used in the treatment of osteoporosis. E09241 with an N-methylpyridine-chlorofuranformamide structural skeleton was previously identified to decrease bone loss and thus protect against osteoporosis in ovariectomized rats through increasing osteoprotegerin (OPG) expression. In this study, 36 derivatives of E09241 (3a) were prepared. The synthesis, up-regulation of OPG activities, SAR (structure-activity relationship), and cytotoxicity of these compounds are presented. Compounds with good up-regulating OPG activities could inhibit RANKL (the receptor activator of nuclear factor-kappa B ligand)-induced osteoclastogenesis in RAW264.7 cells. Particularly, compounds 3c and 3i1 significantly reduced NFATc1 and MMP-9 protein expression through inhibition of the NF-κB and MAPK pathways in RANKL induced RAW264.7 cells. In addition, compounds 3c and 3v significantly promoted osteoblast differentiation in MC3T3-E1 cells in osteogenic medium, and compounds 3c, 3v, and 3i1 obviously increased OPG protein expression and secretion in MC3T3-E1 cells. Furthermore, the pharmacokinetic profiles, acute toxicity, and hERG K+ channel effects of compounds 3a, 3c, 3e, 3v, and 3i1 were investigated. Taken together, these results indicate that N-methylpyridine-chlorofuranformamide analog 3i1 could serve as a promising lead for the development of new agents for treating osteoporosis.
