We have investigated core-crosslinked star polymer nanoparticles designed with tunable release chemistries as potential nanocarriers for a photoactive Re(I) organometallic complex. The nanoparticles consisted of a brush poly(oligo-ethylene glycol)methyl ether acrylate (POEGA) corona and a cross-linked core of non-biodegradable N,N’-methylenebis(acrylamide) (MBAA) and either pentafluorophenyl acrylate (PFPA), 3-vinyl benzaldehyde (VBA) or diacetone acrylamide (DAAM). Each star was modified with an amine functionalized photodynamic agent (i.e. a rhenium(i) organometallic complex) resulting in the formation of either a stable amide bond (POEGA-star-PFPA), or hydrolytically labile aldimine (POEGA-star-VBA) or ketimine bonds (POEGA-star-DAAM). These materials revealed linker dependent photo- and cytotoxicity when tested in vitro against non-cancerous lung fibroblast MRC-5 cells and HeLa human cervical cancer cells: the toxicity results correlated with final intracellular Re concentrations.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 2749-11-3, you can contact me at any time and look forward to more communication. SDS of cas: 2749-11-3.

Betulinic acid (BA) is a naturally occurring triterpenoid with several biological properties already described, including immunomodulatory activity. Here we investigated the immunomodulatory activity of eight semisynthetic amide derivatives of betulinic acid. Screening of derivatives BA1-BA8 led to the identification of compounds with superior immunomodulatory activity than BA on activated macrophages and lymphocytes. BA5, the most potent derivative, inhibited nitric oxide and TNFa production in a concentration-dependent manner, and decreased NF-kappa B activation in Raw 264.7 cells. Additionally, BA5 inhibited the proliferation of activated lymphocytes and the secretion of IL-2, IL-4 IL-6, IL-10, IL-17A and IFN gamma, in a concentration-dependent manner. Flow cytometry analysis in lymphocyte cultures showed that treatment with BA5 induces cell cycle arrest in pre-G1 phase followed by cell death by apoptosis. Moreover, BA5 also inhibited the activity of calcineurin, an enzyme that plays a critical role in the progression of cell cycle and T lymphocyte activation. BA5 has a synergistic inhibitory effect with dexamethasone on lymphoproliferation, showing a promising profile for drug combination. Finally, we observed immunosuppressive effects of BA5 in vivo in mouse models of lethal endotoxemia and delayed type hypersensitivity. Our results reinforce the potential use of betulinic acid and its derivatives in the search for potent immunomodulatory drugs.

Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels. 2749-11-3, Name is (S)-2-Aminopropan-1-ol, molecular formula is C3H9NO. In an article, author is Kumar, Alok,once mentioned of 2749-11-3, SDS of cas: 2749-11-3.

This study deals with removal of phenolic compounds from water by perstraction, and poly(ether-b-amide) (PEBA) membranes were selected because of their excellent permeability to phenolics. The permeability, diffusivity and solubility of model phenolic compounds (including the simplest phenol (PhOH), 4-methylphenol (MePhOH), 4-nitrophenol (O2NPhOH) and 4-chlorophenol (ClPhOH)) in the membrane were investigated. The membrane showed a permeability in the order of ClPhOH > MePhOH > O2NPhOH > PhOH, while the diffusivity followed the order of PhOH > MePhOH > O2NPhOH > ClPhOH. Based on the resistance-in-series model, the mass transfer characteristics of the liquid/membrane/liquid perstraction system was analyzed, and the individual mass transfer resistances from the various steps of the perstraction process were estimated. It was revealed that the membrane resistance was significant, and the mass transfer resistance at the downstream side of the membrane as a result of phenol desorption from the membrane and boundary layer effects was not negligible. While the strong affinity between PEBA and phenolics was responsible for the good phenol permeability in the membrane, it also resulted in a high resistance to phenol desorption from the membrane. The use of an alkaline stripping agent can effectively enhance phenol removal from water by reducing the mass transfer resistances of the liquid boundary layers and phenol desorption at the downstream side of the membrane. For a given phenolic compound, the enhancement in mass transfer rate was affected by the alkaline concentration, and the enhancement was particularly significant when thin membranes were used.

The first example of a ruthenium-catalyzed C-H bond alkylation via six-membered ruthenacycles is presented. This is disclosed for the C-H bond alkylation of biologically relevant cyclic amides with maleimide derivatives. The cyclic tertiary amide core acted as a directing group (DG) enabling formation of six-membered cycloruthenated species responsible for the control of the regio- and site selectivity of the reaction as well as the excellent functional group tolerance. Unexpectedly, cyclic amides were found to be better DGs than pyridine-containing ones or cyclic imides for this type of C-H bond functionalization.

In the present report, we describe the synthesis of the amide derivative, N-(2,4-dichlorophenyl)-1-naphthamide, 3, via a facile chemical route. The title compound was isolated in 86% yield. The structure of compound 3 was established using spectroscopic methods and X-ray crystallography. In the crystal structure of 3, supramolecular assembly is dominated by classical N-H center dot center dot center dot O hydrogen bonding and C-Cl center dot center dot center dot pi halogen bonding interactions which were examined in detail using several theoretical methods and DFT calculations. The optimized geometric parameters of compound 3 were calculated using density functional theory (DFT/B3LYP and DFT/M06-2X) quantum chemical methods with the 6-311++G(d,p) basis set using the crystallographic coordinates. Additionally, fragments contributing to the HOMO and LUMO molecular orbitals were investigated at the same level of theory. The nature and various types of intermolecular interactions in the crystal structure were also realized by Hirshfeld surface analysis. The biological properties such as anti-Alzheimer’s potential were also assessed which reveals strong acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory effects. Compound 3 was 16-fold more active inhibitor of acetylcholinesterase compared to neostigmine with an IC50 value of 1.044 +/- 0.76 mu M in addition to 21-fold strong inhibition against butyrylcholinesterase. The in vitro bioactivity results were further strengthened by the molecular docking analysis revealing the presence of several important interactions with the active site residues from cholinesterase (AChE & BChE) enzymes.

Dehydrogenative amide bond formation from alcohols and amines has been regarded as an atom-economic and sustainable process. Among various catalytic systems, N-heterocyclic carbene (NHC)-based Ru catalytic systems have attracted growing interest due to the outstanding properties of NHCs as ligands. Herein, an NHC/Ru complex (1) was prepared and its structure was further confirmed with X-ray crystallography. In the presence of Cs2CO3, two NHC/Ru-based catalytic systems were disclosed to be active for this amide synthesis. System A, which did not contain any added ligand, required a catalyst loading of 1.00 mol%. Interestingly, improved catalytic performance was realized by the addition of an NHC precursor (L). Optimization of the amounts of L and other conditions gave rise to system B, a much more potent system with the Ru loading as low as 0.25 mol%. Moreover, an NHC-Ru-carbonate complex 6 was identified from the refluxing toluene of 1 and Cs2CO3, and further investigations revealed that 6 was an important intermediate for this catalytic reaction. Based on the above results, we claimed that the role of Cs2CO3 was to facilitate the formation of key intermediate 6. On the other hand, it provided the optimized basicity for the selective amide formation.

Chemistry can be defined as the study of matter and the changes it undergoes.

The 6Mg(NH2)(2)-9LiH-LiBH4 composite system has a maximum reversible hydrogen content of 4.2 wt% and a predicted dehydrogenation temperature of about 64 degrees C at 1 bar of H-2. However, the existence of severe kinetic barriers precludes the occurrence of de/re-hydrogenation processes at such a low temperature (H. Cao, G. Wu, Y. Zhang, Z. Xiong, J. Qiu and P. Chen, J. Mater. Chem. A, 2014, 2, 15816-15822). In this work, Li3N and YCl3 have been chosen as co-additives for this system. These additives increase the hydrogen storage capacity and hasten the de/re-hydrogenation kinetics: a hydrogen uptake of 4.2 wt% of H-2 was achieved in only 8 min under isothermal conditions at 180 degrees C and 85 bar of H-2 pressure. The re-hydrogenation temperature, necessary for a complete absorption process, can be lowered below 90 degrees C by increasing the H-2 pressure above 185 bar. Moreover, the results indicate that the hydrogenation capacity and absorption kinetics can be maintained roughly constant over several cycles. Low operating temperatures, together with fast absorption kinetics and good reversibility, make this system a promising on-board hydrogen storage material. The reasons for the improved de/re-hydrogenation properties are thoroughly investigated and discussed.

The reaction of NHC alane adducts NHC center dot AlH3 (NHC = N-Heterocyclic Carbene; NHC = iPr(2)Im, Dipp(2)Im; R(2)Im = 1,3-di-organyl-imidazolin-2-ylidene; iPr = isopropyl; Dipp = 2,6-diisopropylphenyl) with secondary amines HNR2 [R = iPr, Ph, Si(CH3)(3)] and the reaction of the trimethylamine alane adduct (NMe3)center dot AlH3 with secondary amines followed by the reaction with the NHC both lead to formation of the compounds NHC center dot AlH2(NR2) 1-6 [NHC = iPr(2)Im, Dipp(2)Im, R = iPr, Ph, Si(CH3)(3)]. These compounds are stable in solution up to temperatures of 90 degrees C. In contrast to the NHC alane adduct (iPr(2)Im)center dot AlH3 (I) and (Dipp(2)Im)center dot AlH3 (II), no ring expansion reaction to six-membered heterocyclic rings or ring opening reaction were observed for the reaction of (iPr(2)Im)center dot AlH2(NR2) with another equivalent of the NHCs iPr(2)Im or Dipp(2)Im. Thus, amide substituted NHC alane adducts show a much high stability compared to the parent compounds NHC center dot AlH3. Furthermore, the reaction of NHC center dot AlH3 (NHC = iPr(2)Im, Dipp(2)Im) with 2,4,6-trimethylphenol leads to the formation of the adducts NHC center dot AlH3-n(OMes)(n) 7-10 (n = 1, 2). The reaction with n >= 3 equivalent of 2,4,6-trimethylphenol afforded the imidazolium salt [Dipp(2)ImH](+)[Al(OMes)(4)](-) (11). The compounds 7-11 are also stable with respect to ring expansion after addition of another equivalent NHC.
