Tryptophan catabolism mediated by indoleamine 2,3-dioxygenase (IDO) is an important mechanism of peripheral immune tolerance contributing to tumoral immune resistance. IDO inhibition is thus an active area of research in drug development. Recently, our group has shown that tryptophan 2,3-dioxygenase (TDO), an unrelated hepatic enzyme also catalyzing the first step of tryptophan degradation, is also expressed in many tumors and that this expression prevents tumor rejection by locally depleting tryptophan. Herein, we report a structure-activity study on a series of 3-(2-(pyridyl)ethenyl)indoles. More than 70 novel derivatives were synthesized, and their TDO inhibitory potency was evaluated. The rationalization of the structure-activity relationships (SARs) revealed essential features to attain high TDO inhibition and notably a dense H-bond network mainly involving His55 and Thr254 residues. Our study led to the identification of a very promising compound (58) displaying good TDO inhibition (Ki = 5.5 muM), high selectivity, and good oral bioavailability. Indeed, 58 was chosen for preclinical evaluation.

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.Synthetic Route of 854778-47-5, you can also check out more blogs about854778-47-5

Smooth moves with a nifty side step: A gold-catalyzed transformation of alpha-(2-indolyl) propargylic alcohols with imines in the presence of the oxidant 8-isopropylquinoline N-oxide provided rapid access to highly functionalized dihydro-gamma-carbolines (see scheme). The reaction mechanism is proposed to involve intermolecular trapping of an alpha-carbonyl gold carbenoid intermediate, followed by cyclization and a novel gold-assisted 1,2-acyl migration.

Reduction-sensitive, amphiphilic dextran derivatives were developed from disulfide-linked dextran-g-poly-(N-epsilon-carbobenzyloxy-l-lysine) graft polymer (Dex-g-SS-PZLL), and used as theranostic nanocarriers for chemotherapy and MR imaging. Dex-g-SS-PZLLs were synthesized by click conjugation between azidized dextran (Dex-N3, 40 kD) and alpha-alkyne-SS-PZLL (degree of polymerization = 10, 15 and 25). The chemical structures of dextran derivatives were characterized by Fourier transform infrared spectroscopy and nuclear magnetic resonance analyses. Owing to their amphiphilic nature, these copolymers can self-assemble into spherical nanosized micelles in an aqueous medium, as confirmed by fluorometry, transmission electron microscopy and dynamic light scattering. Interestingly, the hydrodynamic radii of the micelles (65-100 nm in diameter) were dependent on the block length of PZLL, and their critical micelle concentrations were in the range of 0.020-0.007 mg mL-1, which decreased as the length of PZLL increased. The anticancer drug doxorubicin (DOX) and superparamagnetic iron oxide (SPIO) nanoparticles (NPs), as the magnetic resonance imaging (MRI) contrast agent, were simultaneously encapsulated in the hydrophobic core of the micelles by the dialysis method. The release profiles of encapsulated DOX from SPIO/DOX-loaded micelles were shown to be rapid in the presence of 10 mM glutathione (GSH) within 24 h, whereas less than 30% DOX was released from reduction insensitive Dex-g-PZLL micelles in 48 h. Only about 35% DOX was released from Dex-g-SS-PZLL micelles in the same timeframe. According to the in vitro cytotoxicity test, it was found that reduction-sensitive micelles showed higher toxicity to HepG2 cancer cells than the reduction-insensitive micelles incubated with equivalent DOX concentration. Flow cytometry and fluorescence microscopy analyses further demonstrated that the reduction-sensitive micelles exhibited faster drug release behavior than reduction-insensitive micelles, which also led to higher cytotoxicity. The SPIO/DOX-loaded micelles demonstrated excellent MRI contrast enhancement, and the r2 relaxivity values of the SPIO/DOX-loaded micelles were up to 261.3 Fe mM-1 s-1. Consequently, these reduction-sensitive amphiphilic dextran derivatives are promising theranostic nanocarriers for MR imaging and chemotherapy.

The versatility and potential of a norcoclaurine synthase (NCS) from Coptis japonica NCS2 has been investigated, together with the development and application of a novel fluorescence-based high-throughput assay using nearly forty amines/aldehydes. The stereocontrol exerted by CjNCS2 on selected non-natural substrates has been determined, where the tetrahydroisoquinolines (THIAs) were formed as the (1S)-isomer in >95% ee, as observed with the natural product norcoclaurine. Docking calculations involving THIA mechanism intermediates, utilising the reported Thalictrum flavum NCS X-ray crystallographic structure, were carried out and combined with the CjNCS2 screening results to further understand the mode of action of NCS. These findings suggested that in addition to the key active-site residues K122 and E110, D141 is also mechanistically essential for the enzymatic transformation. The exceptional tolerance of NCS towards aldehyde substrates is furthermore supported by our proposed mechanism in which the aldehydes protrude out of the enzymatic pocket. Copyright

Breast cancer is the most prevalent cancer in women. The development of resistances to therapeutic agents and the absence of targeted therapy for triple negative breast cancer motivate the search for alternative treatments. With this aim in mind, we synthesised new derivatives of troglitazone, a compound which was formerly used as an anti-diabetic agent and which exhibits anti-proliferative activity on various cancer cell lines. Among the compounds prepared, some displayed micromolar activity against hormone-dependent and hormone-independent breast cancer cells. Furthermore, the influence of the compounds on the viability of primary cultures of human hepatocytes was evaluated. This enabled us to obtain for the first time interesting structure-toxicity relationships in this family of compounds, resulting in 6b and 8b, which show good anti-proliferative activities and poor toxicity towards hepatocytes, compared to troglitazone.

A “bridged” bis-cyclopentadienyl complex which can be advantageously used for the formation of a catalytic system active in the (co)polymerization of ethylene and other alpha-olefins is represented by means of the following formula (II): wherein: M represents a metal selected from titanium, zirconium or hafnium; A’ and A” each independently represent an anion containing an eta5-cyclopentadienyl ring coordinated to M; R’ or R” each independently represents a group of an anionic nature ?-bound to the metal M; B represents an unsaturated bivalent organic residue having from 1 to 30 carbon atoms, bound, respectively, to the ring of group A’ and to the -CH2- methylene group by means of unsaturated carbon atoms. This complex, combined with a suitable cocatalyst, forms a catalyst with a high activity in the polymerization of olefins, producing polymers with a high molecular weight, especially in the case of the copolymerization of ethylene with a second alpha-olefin.

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, 526-55-6, molcular formula is C10H11NO, introducing its new discovery. Recommanded Product: 526-55-6

A tandem reaction of N’-(2-alkynylbenzylidene) hydrazone with alcohol in the presence of oxygen co-catalyzed by silver triflate and palladium chloride under mild conditions is reported, providing H-pyrazolo [5,1-alpha] isoquinolines in good yields. During the transformation, isoquinolinium-2-yl amide was the key intermediate via a silver(I)-catalyzed 6-endo cyclization of N’-(2-alkynylbenzyli- dene)hydrazone. The presence of a palladium catalyst and molecular oxygen promoted the oxidation of the alcohol to the aldehyde or ketone. Subsequent nucleophilic attack of the in situ generated enolate to isoquinolinium-2-yl amide, intramolecular condensation, and aromatization afforded the H-pyrazolo- [5,1-alpha]isoquinolines. The easily available starting materials, good substrate generality, mild reaction conditions, and experimental ease should make this method attractive for further library construction.
