A Diaminocyclopentadienone iron tricarbonyl complex has been applied in chemoselective hydrogen transfer reductions. This bifunctional iron complex demonstrated a broad applicability in mild conditions in various reactions, such as reduction of aldehydes over ketones, reductive alkylation of various functionalized amines with functionalized aldehydes and reduction of α,β-unsaturated ketones into the corresponding saturated ketones. A broad range of functionalized substrates has been isolated in excellent yields with this practical procedure.

Human African trypanosomiasis is a neglected infectious disease that affects mostly people living in the rural areas of Africa. Current treatment options are limited to just four drugs that have been in use of four to nine decades. The life-threatening to

Two-photon imaging is an emerging tool for biomedical research and clinical diagnostics. Electron donor–acceptor (D–A) type molecules are the most widely employed two-photon scaffolds. However, current D–A type fluorophores suffer from solvatochromic quenching in aqueous biological samples. To address this issue, we devised a novel class of D–A type green fluorescent protein (GFP) chromophore analogues that form a hydrogen-bond network in water to improve the two-photon efficiency. Our design results in two-photon chalcone (TPC) dyes with 0.80 quantum yield and large two-photon action cross section (210 GM) in water. This strategy to form hydrogen bonds can be generalized to design two-photon materials with anti-solvatochromic fluorescence. To demonstrate the improved in vivo imaging, we designed a sulfide probe based on TPC dyes and monitored endogenous H2S generation and scavenging in the cirrhotic rat liver for the first time.

In the present study, a series of twenty-two 2-benzylidene-1-indanone derivatives were synthesised and evaluated as inhibitors of recombinant human monoamine oxidase (MAO) A and B. The 2-benzylidene-1-indanone derivatives are structurally related to a series of benzylideneindanone derivatives which has previously been found to be MAO-B inhibitors. This study finds that the 2-benzylidene-1-indanones are MAO-B specific inhibitors with IC50values 50?50?=?0.131?μM). An analysis of the structure–activity relationships for MAO-B inhibition show that substitution on the A-ring with a 5-hydroxy group and on the B-ring with halogens and the methyl group yield high potency inhibition. It may therefore be concluded that 2-benzylidene-1-indanone analogues are promising leads for design of therapies for disorders such as Parkinson's disease.

In the effort of finding novel acetyl cholinesterase (AChE) inhibitors to improve the efficacy of Alzheimer's disease (AD) treatment, series of substituted aryl-1′-methyldispiro[indan-2,2′ pyrrolidine-3′, 2"-indan]-1,3,1′-trione and substituted 7′-aryl-5′, 6′,7′,7a′-tetrahydrodispiro-[indane-2,5′-pyrrolo[1,2-c] [1,3]thiazole-6′,2"-indan]-1,3,1"-trione analogues were synthesized using [3+2]-cycloaddition reactions. These newly synthesized pyrrolidine compounds were assayed for their biological activity using Ellman's method. The structural elucidation of the compounds was performed by using 1H-NMR, 13C-NMR, ESI-MS spectra and elemental analyses. Eight out of twenty synthesized compounds showed more than 50% inhibition at concentration of 10 μM. Compound 2e, 2i and 3e were among the most active one, giving IC50 value as 3.3 μM for 2e, 3.7 μM for 2i and 5.5 μM for 3e, respectively. Lineweaver-Burk plot indicated that 2i inhibits AChE in a competitive manner. Molecular modelling study was performed to disclose the binding interaction of these compounds with the active site of AChE.

A series of fourteen dispiropyrrolidines were synthesized using [3+2]-cycloaddition reactions and were screened for their antimycobacterial activity against Mycobacterium tuberculosis H37Rv in HTS (High Throughput Screen). Most of the compounds showed moderate to good activity with MIC of less than 20 μM. Compound 4′-(4-bromophenyl)-1′- methyldispiro[acenaphthylene-1,2′-pyrrolidine-3′,2″-indane]-2, 1″(1H)-dione (4c) was found to be the most active with MIC of 12.50 μM.
