Synthesis and evaluation of 4 ‘,5 ‘-dihydrospiro[piperidine-4,7 ‘-thieno [2,3-c]pyran] analogues against both active and dormant Mycobacterium tuberculosis

Need for new drugs to fight against tuberculosis (TB) is increasing day by day. In the present work we have taken a spiro compound (GSK 2200150A) reported by GSK as a lead and we modified the structure of the lead to study the antitubercular activity. For structure activity profiling twenty-one molecules have been synthesized, characterized and evaluated for their antimycobacterial potency against both active and dormant TB. Compound 06, 1-((4-methoxyphenyl) sulfonyl)-4′,5′-dihydrospiro[piperidine-4,7’-thieno[2,3-c]pyran] was found to be the most potent compound (MIC: 8.23 mu M) in active TB and was less effective than the lead but more potent than standard first line drug ethambutol. It was also found to be more efficacious than Isoniazid and Rifampicin and equipotent as Moxifloxacin against dormant Mycobacterium tuberculosis (MTB). Compound 06 also showed good inhibitory potential against over expressed latent MTB enzyme lysine epsilon-amino transferase with an IC50 of 1.04 +/- 0.32 mu M. This compound is a good candidate for drug development owing to potential against both active and dormant stages of MTB. (C) 2017 Elsevier Ltd. All rights reserved.

Preparation, Characterization, and Catalytic Property of a Cu(II) Complex with 2-Carboxybenzaldehyde-p-Toluenesulfonyl Hydrazone Ligand

Metal-organic complex hybrid materials constructed from carboxylate ligands and hydrazone ligands have exhibited potential application in many fields. In order to enrich the applications of the metai-organic complex materials, a new hydrazone ligand contains carboxylate group, 2-carboxybenzaldehyde- p-toluenesulfonyl hydrazone (L1), and its Cu(II) complex (C2), have been prepared. The structure of L1 was determined by elemental analysis, IR spectra and single crystal X-ray diffraction, and the composition of Cu(II) complex (C2) has also been determined by elemental analysis, IR and UV spectra. The catalytic activity for A(3) coupling reaction of benzaldehyde, piperidine, and phenylacetylene has been investigated. The results show that Cu(II) complex displays a 100 % selectivity to the product of propargylamine during A(3) coupling reaction and benzaldehyde conversions were 95.3, 94.2, and 93.4 % at 120 degrees C for 12 h in the first, second, and third reaction cycles, respectively.

One-Pot Tandem Hiyama Alkynylation/Cyclizations by Palladium(II) Acyclic Diaminocarbene (ADC) Complexes Yielding Biologically Relevant Benzofuran Scaffolds

A series of palladium acyclic diaminocarbene (ADC) complexes of the type cis-[((RNH)-N-1)(R-2)methylidene]-PdCl2(CNR1) [R-1 = 2,4,6-(CH3)(3)C6H2: R-2 = NC5H10 (2); NC4H8 (3); NC4H8O (4)] were used not only to perform the C-sp(2)-C-sp Hiyama coupling between aryl iodide and triethoxysilylalkynes but also to subsequently carry out the one-pot tandem Hiyama alkynylation/cyclization reaction between 2-iodophenol and triethoxysilylalkynes, giving a convenient time-efficient access to the biologically relevant benzofuran compounds. The palladium ADC complexes (2-4) were conveniently synthesized by the nucleophilic addition of secondary amines, namely, piperidine, pyrrolidine, and morpholine on the cis-{(2,4,6-(CH3)(3)C6H2)NC}(2)PdCl2 in moderate yields (ca. 61-66%).

Structural basis for potent and broad inhibition of HIV-1 RT by thiophene[3,2-d] pyrimidine non-nucleoside inhibitors

Rapid generation of drug-resistant mutations in HIV-1 reverse transcriptase (RT), a prime target for anti-HIV therapy, poses a major impediment to effective anti-HIV treatment. Our previous efforts have led to the development of two novel non-nucleoside reverse transcriptase inhibitors (NNRTIs) with piperidine-substituted thiophene[3,2-d]pyrimidine scaffolds, compounds K-5a2 and 25a, which demonstrate highly potent anti-HIV-1 activities and improved resistance profiles compared with etravirine and rilpivirine, respectively. Here, we have determined the crystal structures of HIV-1 wild-type (WT) RT and seven RT variants bearing prevalent drug-resistant mutations in complex with K-5a2 or 25a at similar to 2 angstrom resolution. These high-resolution structures illustrate the molecular details of the extensive hydrophobic interactions and the network of main chain hydrogen bonds formed between the NNRTIs and the RT inhibitor-binding pocket, and provide valuable insights into the favorable structural features that can be employed for designing NNRTIs that are broadly active against drug-resistant HIV-1 variants.

Traceless Redox-Annulations of Alicyclic Amines

Amines such as 1,2,3,4-tetrahydroisoquinoline undergo redox–neutral annulations with ortho-(nitromethyl)benzaldehyde. Benzoic- acid acts as a promoter in these reactions, which involve concurrent amine alpha-C-H bond and N-H bond functionalization. Subsequent removal of the nitro group provides access to tetrahydroprotoberberines not accessible via typical redox-annulations. Also reported are decarboxylative annulations of ortho-(nitromethyl)benzaldehyde with proline and pipecolic acid.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 2873-29-2. Formula: C12H16O7.

Iminium ion-enamine cascade reaction enables the asymmetric total syntheses of aspidosperma alkaloids vincadifformine and ervinceine

Asymmetric total synthesis of (+)-vincadifformine and (+)-ervinceine is reported by utilizing an iminium ion triggered cascade reaction using chiral 3,3-disubstituted piperidine imine and 2,3-disubstituted indole derivatives coupling partner. In the first generation total synthesis, the pivotal imine is prepared in excellent stereoselectivity but in moderate yield involving a Birch reduction-alkylation strategy. Furthermore, to improve upon the synthesis of the decisive imine, the more practical second generation route is devised through a Johnson-Claisen rearrangement to access chiral 3,3-disubstituted piperidinone in excellent yield and stereoselectivity. Apart from synthesizing (+)-vincadifformine, this strategy is also exploited for the first asymmetric total synthesis of (+)-ervinceine employing an iminium ion mediated cascade reaction. This distinctive strategy simultaneously sets up two new rings, two new stereogenic centers, and three new sigma bonds in a single operation. (C) 2018 Elsevier Ltd. All rights reserved.
