GDC-0339 is a novel small molecule pan-Pim kinase inhibitor that was discovered as a potential treatment of multiple myeloma. During the in vitro and in vivo metabolite profiling of GDC-0339, a metabolite was detected that had the same elemental composition as the parent but was distinct with respect to its chromatographic separation and mass spectrometric fragmentation pattern. High resolution...

When cultures of Escherichia coli are partially inhibited by sulfonamides they accumulate a diazotizable and nonacetylable amine in the medium (Fox, 1942). The amine was isolated by Stetten and Fox (1945) and characterized by Shive et al. (1947) as 4-amino-5-imidazole carboxamide. The latter authors suggested that the amine was a precursor of purines as it only required the addition of a one ca...

We report here the crystal structure of a ten-coordinate lanthanum(III) metal coordinated by five bidentate ethyl-enedi-amine ligands, [La(C2H8N2)5]Cl3·C2H8N2·CH2Cl2. One free ethyl-enedi-amine mol-ecule and three Cl(-) anions are also located in the asymmetric unit. The overall structure is held together by an extensive hydrogen-bonding network between the Cl(-) anions and the NH groups on the...

The potent antihypertensive drug reserpine inhibits the transport of biogenic amines into adrenal chromaffin granules and synaptic vesicles. Reserpine acts by binding almost irreversibly to the vesicular amine transporter, and this interaction has been used both to study the mechanism of transport and to purify the protein responsible. Recent isolation of a cDNA for the rat chromaffin granule a...

To enhance the carbon dioxide (CO2) uptake of metal-organic frameworks (MOFs), amine functionalization of their pore surfaces has been studied extensively. In general, amine-functionalized MOFs have been synthesized via post-synthetic modifications. Herein, we introduce a one-step construction of a MOF ([(NiLethylamine)(BPDC)] = MOFNH2; [NiLethylamine](2+) = [Ni(C12H32N8)](2+); BPDC(2-) = 4,4'-...

In the title compound, C24H40N4S3 (4+)·2SiF6 (2-)·3CH3OH, the central tertiary amine function is protonated and is connected to three thio-phen-2-yl-methyl-amino-n-propyl groups, forming the arms of a T-shaped cation that has two pockets. Each arm contains one protonated secondary amine function, and each pocket is occupied by one SiF6 (2-) anion bonded via two N-H⋯F inter-actions with the prot...

A method was developed for the preparation of microcapsules containing a reactive amine with potential applications in self-healing polymers. Amine core microcapsules were prepared by interfacial polymerization of an isocyanate and an amine stabilized by an inverse Pickering emulsion. Microcapsules were successfully isolated, dried, and redispersed in epoxy. Visualization of capsules in cured e...

SBA-15 prepared via ethanol extraction for template removing was grafted with three kinds of amine precursors (mono-, di-, tri-aminosilanes) to synthesis new CO₂ adsorbents. The SBA-15 support and the obtained adsorbents were characterized by X-ray diffraction (XRD), small-angle X-ray scattering (SAXS), N₂ adsorption/desorption, thermogravimetry (TG), elemental analysis, Fourier transform infra...

Several reactions, known from other amine systems for CO2 capture, have been proposed for Lewatit R VP OC 1065. The aim of this molecular modeling study is to elucidate the CO2 capture process: the physisorption process prior to the CO2-capture and the reactions. Molecular modeling yields that the resin has a structure with benzyl amine groups on alternating positions in close vicinity of each ...

Two nanometre gold nanoparticles (AuNPs), bearing sugar moieties and/or thiol-polyethylene glycol-amine (PEG-amine), were synthesised and evaluated for their in vitro toxicity and ability to radiosensitise cells with 220 kV and 6 MV X-rays, using four cell lines representing normal and cancerous skin and breast tissues. Acute 3 h exposure of cells to AuNPs, bearing PEG-amine only or a 50:50 rat...
