Polysuccinimide and its derivatives: Degradable and water soluble polymers (review)

Interest for water soluble polymers which show biocompatibility and degradability is growing due to their potential applications in medical sciences. Polysuccinimide (PSI), commonly synthesized through thermal polymerization, is a polyimide precursor for the production of such biocompatible and degradable polymers namely polyaspartic acid and various polyaspartamides. Polyaspartic acid is usually obtained by hydrolysis of PSI while polyaspartamide is produced by ring opening of PSI using a nucleophilic reagent. The presence of amide linkages in these polymers gives them peptide-like structures which is prone to hydrolysis and subsequent degradation. These derivatives could be potential substitutes for different polyamino acids in many medical applications. This review compiles the works carried out on developing polysuccinimide and its derivatives as well as the main synthetic routs and characterization methods.

Synthetic oleanane triterpenoids enhance blood brain barrier integrity and improve survival in experimental cerebral malaria

Background: Cerebral malaria (CM) is a severe complication of Plasmodium falciparum infection associated with high mortality and neurocognitive impairment in survivors. New anti-malarials and host-based adjunctive therapy may improve clinical outcome in CM. Synthetic oleanane triterpenoid (SO) compounds have shown efficacy in the treatment of diseases where inflammation and oxidative stress contribute to pathogenesis. Methods: A derivative of the SO 2-cyano-3,12-dioxooleana-1,9-dien-28-oic acid (CDDO), CDDO-ethyl amide (CDDO-EA) was investigated for the treatment of severe malaria in a pre-clinical model. CDDO-EA was evaluated in vivo as a monotherapy as well as adjunctive therapy with parenteral artesunate in the Plasmodium berghei strain ANKA experimental cerebral malaria (ECM) model. Results: CDDO-EA alone improved outcome in ECM and, given as adjunctive therapy in combination with artesunate, it significantly improved outcome over artesunate alone (p = 0.009). Improved survival was associated with reduced inflammation, enhanced endothelial stability and blood-brain barrier integrity. Survival was improved even when administered late in the disease course after the onset of neurological symptoms. Conclusions: These results indicate that SO are a new class of immunomodulatory drugs and support further studies investigating this class of agents as potential adjunctive therapy for severe malaria.

Clarifying the dehydrogenation pathway of catalysed Li-4(NH2)(3)BH4-LiH composites

The effect of different metal oxides (Co3O4 and NiO) on the dehydrogenation reaction pathways of the Li-4(NH2)(3)BH4-LiH composite was investigated. The additives were reduced to metallic species i.e. Co and Ni which act as catalysts by breaking the B-H bonds in the Li-B-N-H compounds. The onset decomposition temperature was lowered by 32 degrees C for the Ni-catalysed sample, which released 8.8 wt% hydrogen below 275 degrees C. It was demonstrated that the decomposition of the doped composite followed a mechanism via LiNH2 and Li3BN2 formation as the end product with a strong reduction of NH3 emission. The sample could be partially re-hydrogenated (similar to 1.5 wt%) due to lithium imide/amide transformation. To understand the role of LiH, Li-4(NH2)(3)BH4-LiH-NiO and Li-4(NH2)(3)BH4-NiO composites were compared. The absence of LiH as a reactant forced the system to follow another path, which involved the formation of an intermediate phase of composition Li3BN2H2 at the early stages of dehydrogenation and the end products LiNH2 and monoclinic Li3BN2. We provided evidence for the interaction between NiO and LiNH2 during heating and proposed that the presence of Li facilitates a NHx-rich environment and the Ni catalyst mediates the electron transfer to promote NHx coupling.

Carbonate-Catalyzed Room-Temperature Selective Reduction of Biomass-Derived 5-Hydroxymethylfurfural into 2,5-Bis(hydroxymethyl)furan

Catalytic reduction of 5-hydroxymethylfurfural (HMF), deemed as one of the key bio-based platform compounds, is a very promising pathway for the upgrading of biomass to biofuels and value-added chemicals. Conventional hydrogenation of HMF is mainly conducted over precious metal catalysts with high-pressure hydrogen. Here, a highly active, sustainable, and facile catalytic system composed of K2CO3, Ph2SiH2, and bio-based solvent 2-methyltetrahydrofuran (MTHF) was developed to be efficient for the reduction of HMF. At a low temperature of 25 degrees C, HMF could be completely converted to 2,5-bis(hydroxymethyl)furan (BHMF) in a good yield of 94% after 2 h. Moreover, a plausible reaction mechanism was speculated, where siloxane in situ formed via hydrosilylation was found to be the key species responsible for the high reactivity.

Metal and Ligand Effects on the Construction of Divalent Coordination Polymers Based on bis-Pyridyl-bis-amide and Polycarboxylate Ligands

Ten coordination polymers constructed from divalent metal salts, polycarboxylic acids, and bis-pyridyl-bis-amide ligands with different donor atom positions and flexibility are reported. They were structurally characterized by single-crystal X-ray diffraction. The ten coordination polymers are as follows: (1) {[Ni(L-1)(3,5-PDA)(H2O)(3)]2H(2)O}(n) (L-1 = N,N-di(3-pyridyl)suberoamide, 3,5-H(2)PDA = 3,5-pyridinedicarboxylic acid); (2) {[Ni-2(L-1)(2)(1,3,5-HBTC)(2)(H2O)(4)]center dot H2O}(n) (1,3,5-H3BTC = 1,3,5-benzenetricarboxylic acid); (3) {[Ni(L-2)(5-tert-IPA)(H2O)(2)]center dot 2H(2)O}(n) (L-2 = N,N-di(3-pyridyl)adipoamide, 5-tert-H(2)IPA = 5-tert-butylisophthalic acid); (4) [Ni(L-3)(1.5)(5-tert-IPA)](n) (L-3 = N,N-di(4-pyridyl)adipoamide); (5) [Co(L-1)(1,3,5-HBTC)(H2O)](n); (6) {[Co-3(L-1)(3)(1,3,5-BTC)(2)(H2O)(2)]center dot 6H(2)O}(n); (7) [Cu(L-4)(AIPA)](n) (L-4 = N,N-bis(3-pyridinyl)terephthalamide, H(2)AIPA = 5-acetamido isophthalic acid); (8) {[Cu(L-2)(0.5)(AIPA)]MeOH}(n); (9) {[Zn(L-4)(AIPA)]center dot 2H(2)O}(n); and (10) {[Zn(L-2)(AIPA)]center dot 2H(2)O}(n).

Different Co/1,3,5-H3BTC ratios were used to prepare 5 and 6, affording a 2D layer with the sql topology and a 2D layer with the (4 center dot 8(5))(2)(4)(2)(8(3))(2)(8) topology that can be further simplified to an hcp topology. While complex 7 is a 2D layer with the (4(2)6(7)8)(4(2)center dot 6)-3,5L2 topology and 8 is a 2-fold interpenetrated 3D framework with the pcu topology, complexes 9 and 10 are self-catenated 3D frameworks with the (4(24)center dot 6(4))-8T2 and the (4(4)center dot 6(10)center dot 8)-mab topologies, respectively. The effects of the identity of the metal center, the ligand isomerism, and the flexibility of the spacer ligands on the structural diversity of these divalent coordination polymers are discussed. The luminescent properties of 9 and 10 and their photocatalytic effects on the degradation of dyes are also investigated.

Enhancing Physical Properties of Viscose by Preparing Viscose/Keratin/Nano ZnO Composite Fabric

The emulsion of Keratin nano ZnO was prepared by extracting the keratin from wool. Cellulose viscose fabric was treated by plasma and immersed in solution and by special chemical method the fabric was finished with keratin/ZnO. The obtained cellulose composite morphology was studied by FESEM. The peaks shown by FTIR proved the presence of functional groups (amide, polypeptide, O-H and C-H). The result has proven the presence and good distribution of keratin and nano zinc oxide. The treated samples showed very low transmission of UV irradiation indicating good UV blocking. Physical properties of treated samples show that keratin gives the water absorption property to viscose. Abrasion resistance of samples indicates that treated samples have better resistance due to its excellent mechanical properties of keratin/ZnO. The strength of samples shows that keratin has good effect on increasing the strength property of viscose.

A Xanthene-Based Mono-Anionic PON Ligand: Exploiting a Bulky, Electronically Unsymmetrical Donor in Main Group Chemistry

The synthesis of a novel mono-anionic phosphino-amide ligand based on a xanthene backbone is reported, togetherr with the corresponding Ga-I complex, (PON)Ga (PON = 4-(di(2,4,6-trimethylphenyl)phosphino)-5-(2,6-diisopropylanilido)-2,7-di-tert-butyl-9,9-dimethylxanthene). The solid-state structure of (PON)Ga (obtained from X-ray crystallography) reveals very weak O…Ga and P…Ga interactions, consistent with a R2NGa fragment which closely resembles those found in one-coordinate amidogallium systems. Strong N-to-Ga pi donation from the amido substituent is reflected in a very short N-Ga distance (1.961(2) angstrom), while the P…Ga contact (3.076(1) angstrom) is well outside the sum of the respective covalent radii. While the donor properties of the PON ligand towards Ga-I are highly unsymmetrical, oxidation to Ga-III leads to much stronger coordination of the pendant phosphine as shown by P-Ga distances which are up to 20 % shorter. From a steric perspective, the PON ligand is shown to be significantly bulkier than related beta-diketiminate systems, a finding consistent with reactions of (PON)Ga towards O-atom sources that proceed without oligomerization. Despite this, the enhanced P-donor properties brought about by oxidation at gallium are not sufficient to quench the reactivity of the highly polar Ga-O unit. Instead, intramolecular benzylic C-H activation is observed across the Ga-O bond of a transient gallanone intermediate.
