A series of bis[3,5-bis(benzylidene)-4-oxo-1-piperidinyl]amides 1 display potent cytotoxic properties towards a wide range of tumours. A number of the CC50 and IC50 values are in the range of 10-8 M. Specifically, these compounds have the following important properties. First, greater toxicity was demonstrated towards certain tumours than various non-malignant cells. Second, various compounds in series 1 are toxic to a number of human colon cancer and leukaemic cells. Third, these compounds reverse P-gp mediated multidrug resistance. Various prototypic molecules such as 1a,b and 1i were identified as lead molecules for further studies. A representative lead molecule 1b induces apoptosis via internucleosomal DNA fragmentation and PARP cleavage in HSC-2 and HL-60 cells while flow cytometry revealed that this compound blocked the G2/M and S-phases in the cell cycle of human colon cancer HCT-116 cells.

Three Ni(II) complexes of cresol-based Schiffbase ligands, namely [Ni 2(L1)(NCS)3(H2O)2], (1) [Ni2(L2)- (CH3COO)(NCS)2(H 2O)] (2) and [Ni2(L3)(NCS)3] (3), (where L1 = 2,6-bis(N-ethylpyrrolidineiminomethyl)-4-methylphenolato, L2 = 2,6-bis(N-ethylpiperidineiminomethyl)-4-methylphenolato and L3 = 2,6-bis{N-ethyl-N-(3-hydroxypropyl iminomethyl)}-4- methylphenolato), have been synthesized and structurally characterized by X-ray single-crystal diffraction in addition to routine physicochemical techniques. Density functional theory calculations have been performed to understand the nature of the electronic spectra of the complexes. Complexes 1-3 when reacted with 4-nitrophenyl phosphate in 50:50 acetonitrile-water medium promote the cleavage of the O-P bond to form p-nitrophenol and smoothly convert 3,5-ditert- butylcatechol (3,5-DTBC) to 3,5-di-tert-butylquinone (3,5-DTBQ) either in MeOH or in MeCN medium. Phosphatase- and catecholase-like activities were monitored by UV-vis spectrophotometry and the Michaelis-Menten equation was applied to rationalize all the kinetic parameters. Upon treatment with urea, complexes 1 and 2 give rise to [Ni2(L1)(NCS)2(NCO)(H 2O)2] (1′) and [Ni2(L2)- (CH 3COO)(NCO)(NCS)(H2O)] (2′) derivatives, respectively, whereas 3 remains unaltered under same reaction conditions.

Bromodomains are epigenetic reader domains that have recently become popular targets. In contrast to BET bromodomains, which have proven druggable, bromodomains from other regions of the phylogenetic tree have shallower pockets. We describe successful targeting of the challenging BAZ2B bromodomain using biophysical fragment screening and structure-based optimization of high ligand-efficiency fragments into a novel series of low-micromolar inhibitors. Our results provide attractive leads for development of BAZ2B chemical probes and indicate the whole family may be tractable.

Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 2213-43-6, molcular formula is C5H12N2, introducing its new discovery. Quality Control of: 1-Aminopiperidine

(Chemical Equation Presented) The reaction of N,N-dialkylhydrazine/2LiCl adducts with aryl bromides in the presence of Pd2(dba)3 as the palladium source, Xantphos or X-phos as the ligands, toluene as the solvent, and NaOBu-t as the base provides an efficient route to N,N-dialkyl-N?-arylhydrazines. Best results were obtained by using N,N-dialkylhydrazine/2LiCl adducts prepared in situ, omitting their isolation.

A library of star-shaped 2H-imidazolines has been synthesized via Debus-Radziszewski condensation from 1,2-diketones and ketone starting materials. Selective reduction of one imine group of the 2H-imidazole intermediate with LiAlH4 or catalytic flow hydrogenation furnished 2H-imidazolines, which could be conveniently diversified by reacting the amine N with electrophiles, resulting in a set of 21 amide-, carbamate-, urea-, and allylamine-containing products. In total, five points of diversification could be used, which allow the production of a set of functionally diverse compounds. The synthesis of acylated 2H-imidazolidines resulted in intrinsically labile compounds, which spontaneously degraded to acyclic derivatives, as shown for the reaction of 2H-imidazolidine with hexylisocyanate.

Background: Tuberculous meningitis (TBM) is the most severe form of tuberculosis and results in high morbidity and mortality in children. Diagnostic delay contributes to the poor outcome. There is an urgent need for new tools for the rapid diagnosis of TBM, especially in children. Methods: We collected serum samples from children in whom TBM was suspected at a tertiary hospital in Cape Town, South Africa. Children were subsequently classified as having TBM or no TBM using a published uniform research case-definition. Using a multiplex cytokine array platform, we investigated the concentrations of serum biomarkers comprising biomarkers that were previously found to be of value in the diagnosis of adult pulmonary TB (CRP, SAA, CFH, IFN-gamma, IP-10, Apo-AI, and transthyretin) plus other potentially useful host biomarkers as diagnostic candidates for TBM. Findings: Out of 47 children included in the study, 23 (48.9%) had a final diagnosis of TBM and six were HIV infected. A modified version of the adult 7-marker biosignature in which transthyretin was replaced by NCAM1, diagnosed TBM in children with AUC of 0.80 (95% CI, 0.67?0.92), sensitivity of 73.9% (95% CI, 51.6?89.8%) and specificity of 66.7% (95% CI, 44.7?84.4%), with the other six proteins in the signature (CRP, IFN-gamma, IP-10, CFH, Apo-A1, and SAA) only achieving and AUC of 0.75 (95%CI, 0.61?0.90) when used in combination. A new childhood TBM specific 3-marker biosignature (adipsin, Abeta42, and IL-10) showed potential in the diagnosis of TBM, with AUC of 0.84 (95% CI, 0.73?0.96), sensitivity of 82.6% (95 CI, 61.2?95.0%) and specificity of 75.0% (95% CI, 53.3?90.2%) after leave-one-out cross validation. Conclusion: A previously described adult 7-marker serum protein biosignature showed potential in the diagnosis of TBM in children. However, a smaller childhood TBM-specific 3-marker signature demonstrated improved performance characteristics. Our data indicates that blood-based biomarkers may be useful in the diagnosis of childhood TBM and requires further validation in larger cohort studies.
