Tubulin binding agents and corresponding prodrug constructs

A diverse set of tubulin binding agents have been discovered which are structurally characterized, in a general sense, by a semi-rigid molecular framework capable of maintaining aryl-aryl, pseudo pi stacking distances appropriate for molecular recognition of tubulin. In phenolic or amino form, these ligands may be further functionalized to prepare phosphate esters, phosphate salts, phosphoramidates, and other prodrugs capable of demonstrating selective targeting and destruction of tumor cell vasculature.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1317-39-1 is helpful to your research. Related Products of 1317-39-1

Complexes of copper(I) thiocyanate with monodentate phosphine and pyridine ligands and the P(,N)-donor diphenyl(2-pyridyl)phosphine

Copper(I) thiocyanate derivatives were prepared by the reaction of CuNCS with pyridine (py) and tertiary monophosphine ligands [PR3 in general; in detail: PPh3, triphenylphosphine, P(4-FPh)3, tris(4-fluorophenyl)phosphine)], as well as the potentially bidentate ligand diphenyl(2-pyridyl)phosphine (PPh2py). Mechanochemical methods were used in some cases to investigate stoichieometries that were not easily accessible by conventional solution syntheses. Three forms of the resulting adducts of CuNCS/PR3/py-base (1:3-n:n) stoichiometry-all containing four-coordinate copper(I) atoms and monodentate N-thiocyanate groups-were confirmed crystallographically. Mononuclear arrays are defined for [(PPh2py)3-n(py)nCuNCS], n = 0, 1, 2, the monodentate thiocyanate being N-coordinated in all; two polymorphs are observed for the n = 2 complex, both crystallizing in monoclinic P21 (Z = 2) cells with similar cell dimensions, but with aromatic components eclipsed about the Cu-P bond in the PPh3 complex, and staggered in the PPh2py complex. Bridging thiocyanate groups are found in the 1:1:1 CuNCS/PPh2py/2-methylpyridine (mpy) and P(4-FPh)3/mpy complexes, wherein centrosymmetric dimers with eight-membered central rings are obtained: [(R3P)(mpy)Cu(NCS)2Cu(PR3)(mpy)], as is also the case in the parent 1:2 CuNCS/PPh2py adduct [(pyPh2P)2Cu(NCS)2Cu(PPh2py)2]. For the 1:1:1 CuNCS/P(4-FPh)3/py and PPh3/Brmpy (Brmpy = 3-bromo-4-methylpyridine) adducts, and, likely, CuNCS/PPh2py/py (1:1:1), single-stranded polymers of the form [?Cu(NCS)(PR3)(py-base)(Cu)?](?|?) with linearly bridging NCS ligands were obtained. Some derivatives, representative of all forms, display medium to strong green to blue luminescence when excited with radiation at 365 nm. The 31P CPMAS NMR spectroscopic data clearly differentiate the inequivalent phosphorus positions within each system, showing a wide range of 1J(31P,63/65Cu) values ranging from 965 Hz for [Cu(NCS)(PPh2py)3] to 1540 Hz for dimeric [(4-FPh)3P(mpy)Cu(NCS)2Cu(P(4-FPh)3)(mpy)], reflecting the large variations in the Cu-P bond length.

Development of Sensor Based on Copper(II) Thiocyanate Pyridine Polymeric Complex for Detection of Catechol

The reaction of copper(I) thiocyanate with triphenylphosphine, in pyridine, in air and at room temperature, led to the formation of the copper(II) thiocyanate pyridine polymeric complex [Cu2(mu3 CO3)(NCS)2(Py)4]n in the form of deep blue needle-like crystals. Fourier transform infrared spectroscopy (FTIR), elemental analysis (EA), thermogravimetric analysis (TGA) and single crystal X-ray diffraction analysis (XRD) were performed in order to reveal the identity of the obtained complex. The complex is a coordination polymer that crystallizes in the orthorhombic space group Pnma and has a one-dimensional linear structure running along the crystallographic ${a}$ axis. Here, we report the investigation of the electrochemical properties of this polymeric compound, collected in acetonitrile solution and KClO4 as electrolyte, by cyclic voltammetry and square wave voltammetry. The voltammograms showed four peak pairs related to redox processes of copper ion and electroactive ligands. Moreover, we used this compound as modifier of carbon paste electrodes, whose electrochemical properties were studied in different electrolytes and electrochemical redox probes. These studies demonstrate the valuable electrochemical and electrocatalytic properties of the [Cu2(mu3 -CO3)(NCS)2(Py)4]npolymerimmobilized in the carbonaceous matrix. The sensor developed by using the carbon paste method has shown excellent sensitivity for catechol, good repeatability, selectivity, stability, and applicability in detection of catechol in water samples.

Phosphate-free synthesis, optical absorption and photoelectric properties of Cu2ZnGeS4 and Cu2ZnGeSe4 uniform nanocrystals

Copper-based quaternary chalcogenide semiconductor Cu2ZnGeS 4 and Cu2ZnGeSe4 nanocrystals have been synthesized successfully via a simple and convenient one-pot phosphine-free solution approach. Oleylamine was used as both the solvent and reductant for Se or S and benefited the formation of homogeneous quaternary nanocrystals. Scanning transmission electron microscopy-EDS elemental mapping confirms the uniform spatial distribution of four elements in nanocrystals. UV-Vis absorption spectra of Cu2ZnGeS4 and Cu2ZnGeSe4 nanocrystals show strong photon absorption in the entire visible range. The photoresponsive behavior indicates the potential application of Cu 2ZnGeSe4 nanocrystals in solar energy conversion systems.

Trifluoromethylthiolation and Trifluoromethylselenolation of alpha-Diazo Esters Catalyzed by Copper

alpha-Diazo esters are smoothly converted into the corresponding trifluoromethyl thio- or selenoethers by reaction with Me4NSCF3or Me4NSeCF3, respectively, in the presence of catalytic amounts of copper thiocyanate. This straightforward method gives high yields under neutral conditions at room temperature and is applicable to a wide range of functionalized molecules, including diverse alpha-amino acid derivatives. It is well-suited for the late-stage introduction of trifluoromethylthio or -seleno groups into drug-like molecules.

Process for preparing aminobenzocyclobutenes

A process for preparing a 3- or 4-aminobenzocyclobutene comprises aminating a 3- or 4-halo- or sulfonyloxybenzocyclobutene reactant with an aminating agent by heating at a temperature from about 80 C. to a temperature at which dimerization or oligomerization of a benzocyclobutene reactant or product is a significant side reaction, in the presence of a metal-containing catalyst, for a time sufficient to aminate the halo- or sulfonyloxybenzocyclobutene reactant. In another aspect, this invention relates to a process for making a 3- or 4-phthalimido- or maleimidobenzocyclobutene, comprising reacting a 3- or 4-halobenzocyclobutene reactant with a phthalimide or maleimide compound in the presence of a metal-containing catalyst. The resulting phthalimido- or maleimidobenzocyclobutene can be hydrolyzed to a 3- or 4-aminobenzocyclobutene.

High-efficiency perovskite solar cell using cobalt doped nickel oxide hole transport layer fabricated by NIR process

Lead halide perovskite solar cells (PVSCs) have potential toward commercialization because of their high efficiency and low cost. The hole transport layer (HTL) of p-i-n perovskite solar cell is usually made of NiOX. However, the NiOX needs to be processed at 300 C for 15 min for good hole transport property. This long heating time prohibits the development of continuous commercial process. Thus, a rapid heating process for the NiOX film deposition is critical to realize the commercialization of PVSCs in the future. In this study, we develop a facile method to obtain high quality NiOX films annealed by NIR in a short time of 50 s. A short-wave NIR lamp at 2500 K was used to systematically investigate the effect of NIR intensity on the film quality of sol-gel NiOX. The PVSCs fabricated from NIR-annealed NiOX (NIR-NiOX) film show a comparable power conversion efficiency (PCE) to those fabricated from traditional hot-plate annealed-NiOX (HP-NiOX). In addition, the NIR annealed cobalt-doped NiOX (NIR-Co:NiOX) was synthesized to replace pristine NIR-NiOX. The PCE of PVSCs fabricated from this new NiOX film can be increased from 15.99% to 17.77%, which is due to the efficient hole extraction, less charge accumulation, and reducing Voc loss resulting from the improved hole mobility, reduced interface resistance and well-matched work function. Our study paves a way to fulfill the requirements of low cost and low energy consumption of large scale production of high efficiency PVSCs.
