Kang, Dong Wook published the artcileHalogenation of 4-hydroxy/amino-3-methoxyphenyl acetamide TRPV1 agonists showed enhanced antagonism to capsaicin, HPLC of Formula: 33697-81-3, the publication is Bioorganic & Medicinal Chemistry (2010), 18(22), 8092-8105, database is CAplus and MEDLINE.

As an extension of our anal. of the effect of halogenation on thiourea TRPV1 agonists, we have now modified selected 4-hydroxy(or 4-amino)-3-methoxyphenyl acetamide TRPV1 agonists by 5- or 6-halogenation on the aromatic A-region and evaluated them for potency for TRPV1 binding and regulation and for their pattern of agonism/antagonism (efficacy). Halogenation shifted the functional activity at TRPV1 toward antagonism with a greater extent of antagonism as the size of the halogen increased (I > Br > Cl), as previously observed for the thiourea series. The extent of antagonism was greater for halogenation at the 5-position than at the 6-position, in contrast to SAR for the thiourea series. In this series, compounds 55 (I) and 75 showed the most potent antagonism, with K _i (ant) = 2.77 and 2.19 nM, resp., on rTRPV1 expressed in Chinese hamster ovary cells. The compounds were thus ca. 40-60-fold more potent than 6′-iodononivamide.

Kim, Kwang Soo published the artcileDyeing properties of reactive disperse dye having bromoacrylamide group, Application In Synthesis of 18791-02-1, the publication is Journal of the Korean Fiber Society (2001), 38(12), 683-692, database is CAplus.

A reactive disperse azo dye having an α-bromoacrylamido group was synthesized and its dyeing and fastness properties were compared with those of a a disperse dye. The amount of absorbed reactive disperse dye was less on polyester fabric than the disperse dye, and was much higher on nylon fabric. When polyester and nylon fiber were simultaneously dyed, the nylon absorbed more reactive disperse dye than polyester. The use of a carrier or a variation of dyebath pH was not able to provide the same color depth on both fibers. A nylon/polyester union fabric could be dyed with the reactive disperse dye and the color fastness was good to excellent.

Lee, Jung Kul published the artcileModification of chitosan to improve its hypocholesterolemic capacity, SDS of cas: 4584-49-0, the publication is Bioscience, Biotechnology, and Biochemistry (1999), 63(5), 833-839, database is CAplus and MEDLINE.

Cholestyramine is the most widely used bile acid sequestrant in the treatment of hypercholesterolemia. However, cholestyramine has unpleasant side effects as a consequence of its hydrophobic backbone. Therefore, high-capacity bile acid sequestering biopolymers with cationic chitosan derivatives were developed, because electrostatic interactions are important for binding with bile acid anions. Dialkylaminoalkylation and reductive amination of chitosan were done to add dialkylaminoalkyl and an addnl. free amino group at a hydroxyl site in the chitosan backbone resp. and the aminoderivatized chitosan derivatives were quaternized with Me iodide to produce a cationic polyelectrolyte. The in vitro bile acid binding capacity of the chitosan derivatives in aqueous NaCl was measured by reversed-phase HPLC. The binding capacities of sodium glycocholate (a major bile acid) to chitosan, DEAE-chitosan, quaternized DEAE-chitosan, and cholestyramine were 1.42, 3.12, 4.06, and 2.78 mmol/g resin, resp. With quaternized DEAE-chitosan, the bile acid binding capacity increased ∼50% over that of cholestyramine. The bile acid binding capacity of dialkylaminoalkyl chitosan derivatives increased with the number of carbons in the alkyl groups, indicating that hydrophobic interaction is a secondary factor for the sequestration of bile acids.

Cho, Yongsung published the artcileThe SAR analysis of TRPV1 agonists with the α-methylated B-region, Name: 3-Chloro-4-hydroxyphenylacetic acid, the publication is Bioorganic & Medicinal Chemistry Letters (2012), 22(16), 5227-5231, database is CAplus and MEDLINE.

A series of TRPV1 agonists with amide, reverse amide, and thiourea groups in the B-region and their corresponding α-methylated analogs were investigated. Whereas the α-methylation of the amide B-region enhanced the binding affinities and potencies as agonists, that of the reverse amide and thiourea led to a reduction in receptor affinity. The anal. indicated that proper hydrogen bonding as well as steric effects in the B-region are critical for receptor binding.

Wagner, Carl E. published the artcileThe polyhomologation of 1-boraadamantane: mapping the migration pathways of a propagating macrotricyclic trialkylborane, Computed Properties of 5034-06-0, the publication is Journal of the American Chemical Society (2003), 125(40), 12179-12195, database is CAplus and MEDLINE.

Trialkyl and triaryl organoboranes undergo multiple, repetitive homologations upon reaction with dimethylsulfoxonium methylide (1). This multiple homologation reaction, or polyhomologation, produces polymethylene in a living reaction. Applying the polyhomologation reaction to cyclic and polycyclic organoboranes permits the construction of unique oligomeric and polymeric architectures that are not readily accessible by standard olefin polymerization The polyhomologation of 1-boraadamantane·THF (2) by ylide 1 generates novel macrotricyclic trialkylboranes (3). The oxidation of these macrocyclic organoboranes generates a three-armed star polymethylene polymer (4) incorporating a cis,cis-1,3,5-trisubstituted cyclohexane core. Interestingly, only one-third of the initiators lead to product formation, resulting in an observed d.p. 3 times higher than expected. Close examination of the initial stages of polymerization show that 1-boraadamantane·THF reacts with 1 equiv of 1 to afford a monohomologated product. Subsequent homologations were found to contain branch points leading to isomeric tricyclic products after the third, fourth, and fifth methylene insertions. At these stages of homologation, all of the propagating species result in tricyclic trialkylborane cages with collapsed, inverted pyramidal boron centers that are substantially less reactive toward ylide. Approx. two-thirds of the species discontinue polymerization at these stages. However, one-third of these species continue to propagate and eventually result in the formation of giant macrotricyclic polymers of narrow polydispersity. Mol. modeling and kinetic simulation have aided in the anal. of the probable pathways through which the reaction proceeds.

Five heteromultifunctional dye-resist agents containing chloro-s-triazine and α-bromoacrylamide were synthesized and their resist effectiveness on wool were compared. The dye-resist agent with the dichlorotriazinyl group showed better resist effectiveness than the dye-resist agent with the monochlorotriazinyl group. Also, their resist effectiveness was improved by increasing the number of sulfonate groups in the dye-resist agents and the reactive groups in the reactive dyes applied over them.

Three dye resists based on α-bromoacrylamide and three dye resists based on dichlorotriazine were synthesized and their effectiveness and leveling properties were compared on wool. In general, the dichlorotriazine based resist agents displayed higher resist effectiveness in dyeing than their α-bromoacrylamide counterparts. However, the resists based on α-bromoacrylamide exhibited better leveling properties than those based on dichlorotriazine. The resist effectiveness was significantly improved by increasing the number of sulfonate group in the dye-resist agents and the hydrophilic character of anionic dyes applied over them.

Jung, Sung-Hyun published the artcilePalladium-Catalyzed Direct Synthesis, Photophysical Properties, and Tunable Electroluminescence of Novel Silicon-Based Alternating Copolymers, Application In Synthesis of 14799-94-1, the publication is Macromolecules (2000), 33(25), 9277-9288, database is CAplus.

A new class of silicon-based alternating copolymers with a uniform π-conjugated segment regulated by organosilicon units was synthesized using the Heck reaction between distyrylsilane monomers and appropriate arylene dibromides. The incorporation of organosilicon units with the aromatic or aliphatic groups on the silicon atoms into π-conjugated systems improved their processability and interrupted the π-conjugation length. They could be spin-cast onto various substrates to give highly transparent homogeneous thin films. Their glass transition temperatures were in the range 94-127 °C. They show strong absorption bands around 356-416 nm, which corresponds to the π-π* transition of the conjugated segments. The maximum photoluminescence appeared around 440-526 nm in the blue or green emission region. Their optical properties depend on the arylene dibromides in the Heck reaction. The single-layered light-emitting diode of an Al/SiPhPPV or SiHMPPV/ITO glass exhibits a threshold voltage of 10-12 V from the I-V curve. The electroluminescence (EL) of the SiPhPPV or SiHMPPV gives an emissive peak at 450 nm. Furthermore, the multilayered light-emitting diodes of an Al/LiAl/SiPhPVK/PANI/ITO glass and an Al/LiAl/SiPhFPV or SiHMFPV/ITO glass shows a threshold voltage of 6-12 V. The EL device based on SiPhPVK exhibits the blue emissive color at 467 nm, when an operating voltage of 7 V was applied. When an operating voltage of 11 V was applied, however, the EL device emits a white color. The EL spectra of the SiPhFPV and SiHMFPV polymers, obtained at an applied voltage of 12 V, show two strong peaks in the blue emissive region as well as in the green region.

The self-assembly of bolaamphiphiles comprised of a central photochromic dithienylethene (DTE) chromophore was investigated in aqueous media. Irradiation at 254 nm induced a conversion from the open to closed states of the DTE chromophores. Whereas, in water, irradiation produced a photostationary state of 20 : 80 (open/closed), in methanol the ratio improved to 10 : 90 (open/closed). The open → closed transition was accompanied by the formation of 1D nanofibers during incubation in darkness.
