  Excellent antitumor and antimetastatic activities based on novel coumarin/pyrazole oxime hybrids

  摘要：

  A series of hybrids 10a-v based on coumarin/pyrazole oxime have been synthesized, and exhibit good to excellent antitumor activities. Compound 10n has shown remarkable anticancer effect on SMMC-7721 cells (IC50 = 2.08 mu M), which is considerably lower than 5-FU (IC50 = 37.8 mu M) and similar to ADM (IC50 = 2.67 mu M), with little effect on normal hepatic cells LO2. Notably, the suppression experiments of metastatic activities reveal that 10n also displays significant anti-metastasis effects through inhibiting cell migration and invasion in highly metastatic SMMC-7721 cell line, and dose-dependently reverses TGF-beta 1-induced epithelial-mesenchymal transition (EMT) procedure better than ADM. Finally, 10n also possesses low acute toxicity and potent tumor growth inhibitory property against SMMC-7721 cell lines in vivo. Our findings suggest that novel coumarin/pyrazole oxime hybrids are promising therapeutic agent candidates for further research. (C) 2019 Elsevier Masson SAS. All rights reserved.

  A series of bis-pyrazole derivatives were designed and synthesized, and their antitumor effects in vitro and in vivo were investigated. Several compounds displayed good antiproliferative activity with IC50 values in low-micromolar range against three human cancer cell lines in vitro, superior to 5-FU. The most potent compound 10M selectively inhibited human hepatocellular carcinoma cells but not non-tumor

  Thirteen novel ( E)- R-( methoxyimino) benzeneacetate derivatives, the analogues of strobilurins, which contain two pharmacophoric substructures of the methyl ( E)- methoxyiminoacetate moiety and 1,3,5-substituted pyrazole ring, were stereoselectively synthesized. It was found that the coupling reaction could give stereoselectively ( E: Z ca. 14: 1) the key intermediate material ( E)- methyl 2-( hydroxyimino)2- o- tolyl acetate ( 2). An X- ray crystallographic structure determination was carried out in a representative product. The preliminary bioassays indicated that all of the compounds 1 showed potent fungicidal activity against Rhizoctonia solani, Botrytis cinereapers, Gibberella zeae, Physalospora piricola, and Bipolaris mayclis.
