  2-(2-Hydrazinyl)thiazole derivatives: Design, synthesis and in vitro antimycobacterial studies

  摘要：

  In an attempt to discover new potent inhibitors for Mycobacterium tuberculosis (Mtb), a series of 2-(2hydrazinyl)thiazole derivatives with a wide range of substitutions at 2-, 4- and 5-positions were designed by considering Lipinski rule. The designed compounds were synthesized, characterized and evaluated for their inhibitory potential against Mtb, H(37)Rv, by in vitro assay. The compounds, ethyl-4methyl-2-[(E)-24]-(pyridin-2-yl)ethylidene]hydrazin-1-yl]-1,3-thiazole-5-carboxylate, 4d, and ethyl-2[(E)-2-[(2-hydroxyphenyl)methylidenelhydrazin-1-yl]-4-methyl-1,3-thiazole-5-carboxylate, 2i showed noticeable inhibitory activity against Mtb, H37Rv with minimum inhibitory concentration (MIC) of 12.5 pM and 25 1.1M respectively. An attempt has been made to understand the mechanism of action by binding interactions of these molecules with 0-ketoacyl-ACP synthase protein through docking studies. The inhibition constants for compounds 4d and 2i were found to be 1.46 pM and 0.177 pM respectively. (C) 2013 Elsevier Masson SAS. All rights reserved.

• Gold complexes with thiosemicarbazones: reactions of bi- and tridentate thiosemicarbazones with dichloro[2-(dimethylaminomethyl)phenyl-C 1,N ]gold(III), [Au(damp-C 1,N )Cl2]

  Dichloro[2-(N,N-dimethylaminomethyl)phenyl-C1,N]gold(III), [Au(damp-C1,N)Cl2] (1), reacts with salicylaldehyde thiosemicarbazone (H2saltsc), vanilline thiosemicarbazone (Hvantsc), N-methylpyrrole aldehyde thiosemicarbazone (Hmepyrtsc), pyridoxal methylthiosemicarbazone (H2pydoxmetsc), 2-diphenylphosphinobenzaldehyde thiosemicarbazone (HPtsc) or variously substituted acetylpyridine thiosemicarbazones (HapRtsc; R = H, Me, Ph) with cleavage of the Au–N bond and protonation of the dimethylamino group. Compounds of general formulae [Au(Hdamp-C1)Cl(L)]+ (L = Hsaltsc−, vantsc−, mepyrtsc−), [Au(Hdamp-C1)Cl(L)]2+ (L = H2pydoxmetsc) or [Au(Hdamp-C1)(L)]2+ (L = Ptsc−, apRtsc−, R = H, Me, Ph) have been isolated and characterized. The presence of the σ-bonded 2-(dimethylaminomethyl)phenyl ligand is mandatory to prevent reduction of the gold(III) centre. The crystal structures of [Au(Hdamp-C1)Cl(Hsaltsc)](PF6) (3a), [Au(Hdamp-C1)Cl(mepyrtsc)]Cl (3c), [Au(Hdamp-C1)Cl(H2pydoxmetsc)]Cl2·MeOH (4), [Au(Hdamp-C1)(apPhtsc)]Cl2·2 MeOH (5c) and [Au(Hdamp-C1)(Ptsc)]Cl2· 1.5MeOH (6) have been elucidated, showing the gold atoms in distorted square-planar co-ordination environments. The potentially O,N,S-tridentate ligands H2saltsc and H2pydoxmetsc co-ordinate in a bidentate fashion and do not incorporate the OH groups in the chelating framework, whereas HapRtsc or HPtsc co-ordinate in a tridentate manner. Generally, one or more hydrogen atoms of the heterocyclic ligands and/or the NMe2H+ group form hydrogen bridges in the solid state structures. The preliminary results of antiproliferation tests on tumor cells demonstrate the considerable cytotoxicity of these new gold complexes. p

  Aryl hydrazones bearing thiazolyl coumarin hybrids 1–32 were prepared by following 'one-pot' two-steps reaction scheme. Various arylaldehydes were reacted to thiosemicarbazide under acidic condition to form aryl thiosemicarbazone intermediates which in turn treated with 3-bromoacetyl coumarin under basic condition to afford thiazolyl coumarin hybrids 1–32. All hybrids were recognized by EI- and HREI-MS

  The druggability of the tyrosyl-DNA phosphodiesterase 1 (Tdp1) enzyme was investigated in conjunction with topoisomerase 1 inhibition. A novel class of thiazole, aminothiazole and hydrazonothiazole usnic acid derivatives was synthesized and evaluated as Tdp1 inhibitors and their ability to sensitize tumors to topotecan, a topoisomerase inhibitor in clinical use. Of all the compounds tested, four hydrazinothiazole derivatives, 20c, 20d, 20h and 20i, inhibited the enzyme in the nanomolar range. The activity of the compounds was verified by affinity experiments as well as supported by molecular modelling. The most effective Tdp1 inhibitor, 20d, was ton-toxic and increased the effect of topotecan both in vitro and in vivo in the Lewis lung carcinoma model. Furthermore, 20d showed significant increase in the antitumor and antimetastatic effect of topotecan in mice. The results presented here justify compound 20d to be considered as a drug lead for antitumor therapy. (C) 2018 Elsevier Masson SAS. All rights reserved.
