Mao, Weijia;Tay, Xiu Ting;Sarkar, Jit;Wang, Chen-Gang;Goto, Atsushi research published 《 Air-Tolerant Reversible Complexation Mediated Polymerization (RCMP) Using Aldehyde》, the research content is summarized as follows. An air-tolerant reversible complexation mediated polymerization (RCMP) technique, which can be carried out without prior deoxygenation, is developed. The system contains a monomer, an alkyl iodide initiating dormant species, air (oxygen), an aldehyde, N-hydroxyphthalimide (NHPI), and a base. Oxygen is consumed via the NHPI-catalyzed conversion of the aldehyde (RCHO) to a carboxylic acid (RCOOH). The generated RCOOH is further converted to a carboxylate anion (RCOO^–) by the base. The RCOO^– generated in situ works as an RCMP catalyst; the polymerization proceeds with the monomer, alkyl iodide dormant species, and RCOO^– catalyst. Thus, the system is not only air-tolerant but also does not require addnl. RCMP catalysts, which is a notable feature of this system (NHPI is used as an oxidation catalyst for converting RCHO to RCOOH). This technique is amenable to Me methacrylate, Bu methacrylate, benzyl methacrylate, 2-hydroxyethyl methacrylate, and styrene, yielding polymers with relatively low-dispersity (M_w/M_n = 1.20-1.49), where Mw and Mn are the weight- and number-average mol. weights, resp.

Mao, Qing;Dai, Xiwen;Xu, Gaoyang;Su, Yu;Zhang, Bing;Liu, Dan;Wang, Shaojie research published 《 Design, synthesis and biological evaluation of 2-(4-alkoxy-3-cyano)phenyl-6-oxo-1,6-dihydropyrimidine-5-carboxylic acid derivatives as novel xanthine oxidase inhibitors》, the research content is summarized as follows. A series of 2-(4-alkoxy-3-cyano)phenyl-1,6-dihydropyrimidine-5-carboxylic acid derivatives I [R = O, NH; R¹ = i-Pr, allyl, Bn, etc.; R² = H, Me] was synthesized as novel xanthine oxidase (XO) inhibitors. These compounds exhibited remarkable in vitro XO inhibitory potency with IC₅₀ values ranging from 0.0181 μM to 0.5677 μM. Specifically, compounds I [R = NH; R¹ = (CH₂)₂CH(CH₃)₂, 2-methylallyl], with IC₅₀ values of 0.0240 μM and 0.0181 μM, resp., emerged as the most potent XO inhibitors and their potencies were comparable to that of febuxostat. Structure-activity relationship anal. revealed that the Me group at 4-position of pyrimidine ring could damage the potency and the XO inhibitory potency was maintained when carbonyl group was changed to an imino group. Lineweaver-Burk plot anal. revealed that the representative compound I [R = NH; R¹ = (CH₂)₂CH(CH₃)₂] acted as a mixed-type inhibitor. A potassium oxonate induced hyperuricemia model in rats was chosen to further confirm the hypouricemic effect of compound I [R = NH; R¹ = (CH₂)₂CH(CH₃)₂] and the results showed that compound I [R = NH; R¹ = (CH₂)₂CH(CH₃)₂] (5 mg/kg) was able to significantly lower the serum uric acid level. Furthermore, in acute oral toxicity study, no sign of toxicity was observed when the mice were administered with a single 2000 mg/kg oral dose of compound I [R = NH; R¹ = (CH₂)₂CH(CH₃)₂]. These results suggested that compound I [R = NH; R¹ = (CH₂)₂CH(CH₃)₂] was a potent and promising uric acid-lowing agent for the treatment of hyperuricemia.

C. research published 《 MatThermochemical study to assess the energetical and structural effects of nitro substituents in methyl benzoate isomers》, the research content is summarized as follows. Combined exptl. and computational studies were performed aiming the anal. of energetic properties vs structural characteristics of three Me nitrobenzoate isomers (Me 2-nitrobenzoate, M2NB, Me 3-nitrobenzoate, M3NB, Me 4-nitrobenzoate, M4NB). The exptl. studies include the determination of the enthalpy of formation in the condensed state (crystal and liquid) of the compounds by static combustion, and the determination of enthalpies of phase transition, using Differential Scanning Calorimetry, high temperature Calvet microcalorimetry and the Knudsen effusion method. These data were combined to derive the enthalpy of formation of the Me nitrobenzoate isomers in the gaseous phase, at T = 298.15 K. At the computational level, the gas-phase enthalpy of formation of the Me nitrobenzoate isomers were estimated using theor. approaches, resorting to the G3(MP2)//B3LYP composite method and to appropriate hypothetical gas-phase reactions. The enthalpies of formation obtained exptl. and computationally will be discussed and the energetic-structural synergies for the three Me nitrobenzoate, along with other analogous isomers, will be also analyzed.

Malbari, Khushboo D.;Chintakrindi, Anand S.;Ganji, Lata R.;Gohil, Devanshi J.;Kothari, Sweta T.;Joshi, Mamata V.;Kanyalkar, Meena A. research published 《 Structure-aided drug development of potential neuraminidase inhibitors against pandemic H1N1 exploring alternate binding mechanism》, the research content is summarized as follows. The rate of mutability of pathogenic H1N1 influenza virus is a threat. The emergence of drug resistance to the current competitive inhibitors of neuraminidase, such as oseltamivir and zanamivir, attributes to a need for an alternative approach. The design and synthesis of new analogs with alternate approach are particularly important to identify the potential neuraminidase inhibitors which may not only have better anti-influenza activity but also can withstand challenge of resistance. Five series of scaffolds, namely aurones (1a-1e), pyrimidine analogs (2a-2b), cinnamic acid analogs (3a-3k), chalcones (4a-4h) and cinnamic acid linkages (5a-5c), were designed based on virtual screening against pandemic H1N1 virus. Mol. modeling studies revealed that the designed analogs occupied 430-loop cavity of neuraminidase. Docking of sialic acid in the active site preoccupied with the docked analogs, i.e. in 430-loop cavity, resulted in displacement of sialic acid from its native pose in the catalytic cavity. The favorable analogs were synthesized and evaluated for the cytotoxicity and cytopathic effect inhibition by pandemic H1N1 virus. All the designed analogs resulting in displacement of sialic acid suggested alternate binding mechanism. Overall results indicated that aurones can be measured best among all as potential neuraminidase inhibitor against pandemic H1N1 virus.

Three new and original halogenated oxoquinolinecarbohydrazide N-phosphonate derivatives (DHOP-F, DHOP-Cl and DHOP-Br) were prepared from the corresponding 4-oxo-1,4-dihydroquinoline-3-carboxylates (81, 71 and 65% yields, resp.), characterized by IR, ¹H, ¹³C and ³¹P NMR spectroscopy and HRMS and evaluated as corrosion inhibitors for mild steel AISI 1020 in hydrochloric acid media. Electrochem. Impedance Spectroscopy, Linear Polarization Resistance and Weight Loss Study revealed an anticorrosive efficiency of 93.0, 84.2 and 66.8%, resp., for DHOP-Br, DHOP-Cl and DHOP-F, at a very low concentration (0.48 mmol L^-1). Phys. chem. calculations showed that the adsorption process is spontaneous, and all mols. obey the Langmuir theory. Data crossing between electrochem. and gravimetric measurements reveals a protection mechanism of adsorption by organic monolayer formation on the metal surface. Polarization curves proves that the organic mols. are all mixed-type corrosion inhibitors and Atomic Force Microscopy images suggest the formation of a protective layer on the metal surface. Ab initio calculations are in great agreement with the exptl. results and, therefore, used to rationalize the reason why the bromide derivative is the best inhibitor.

Maaskant, Evelien;van Es, Daan S. research published 《 Unexpected Susceptibility of Poly(ethylene furanoate) to UV Irradiation: A Warning Light for Furandicarboxylic Acid?》, the research content is summarized as follows. Poly(ethylene furanoate) (PEF) is widely advocated as renewable alternative to the fossil-based polyester poly(ethylene terephthalate) (PET). Whereas the UV-stability of PET is well-studied, little is known for PEF. Here, we compare the UV-stability of both polyesters after 500 h of UV-irradiation in a Q-SUN xenon arc chamber. Both the virgin and irradiated polyesters were characterized by FTIR, SEC, DSC, NMR, TGA, and MALDI-TOF MS. PET showed only minor signs of degradation under the applied test conditions, while PEF showed significant discoloration, as well as evidence of both crosslinking/chain extension and chain scission. Also the thermal properties and the ability to crystallize of PEF were severely impacted by UV-irradiation Although a detailed study on the degradation mechanism is out of scope for this work, we found indications that Norrish type I and II degradation reactions play an important role in the UV-degradation of PEF.
