Effect of chemical structure on the crosslinking behavior of bismaleimides: Rheological study

The effect of molecular structure on the cure characteristics of bismaleimides (BMIs) was investigated by rheological measurements. BMI resins of different chemical structures were used, prepared from diglycidyl ether of bisphenol A and N-(3-carboxy phenyl) maleimide or N-(4-carboxy phenyl) maleimide. Temperature dependence of the rheological data was correlated to the Arrhenius equation, from which the activation energy of crosslinking was calculated.Upon heating in dynamic curing, viscosity passed through a minimum then sharply increased due to increasing amount of the crosslinking reaction. The temperature at minimum viscosity increased as the chain length became longer. After passing the minimum point, viscosity increased much faster for meta BMIs (3BE1, 3BE2) than para BMIs, however, the difference in the chain length did not show any appreciable difference in the viscosity increase rate (deta*/dT). Nonetheless, the final viscosity was lower for longer chains, because their crosslinking density would be lower.In isothermal curing, the final crosslinking density was expected to increase with temperature, which was shown via the increase in the final viscosity. The gelation time decreased with temperature, and the activation energy of the crosslinking reaction was obtained. Using the reaction kinetics parameters obtained from dynamic scanning calorimeter and Arrhenius type equation, the viscosity change during the isothermal curing was simulated and compared with the measurements.

Synthesis and immunosuppressive activity of novel prodigiosin derivatives

Prodigiosins (Ps) represent a family of naturally occurring red pigments characterized by a common pyrrolylpyrromethene skeleton. Some members of this family have been shown to possess interesting immunosuppressive properties exerted with a novel mechanism of action, different from that of currently used drugs. In fact, Ps inhibit phosphorylation and activation of JAK-3, a cytoplasmic tyrosine kinase associated with a cell surface receptor component called common gamma-chain, which is exclusive of all IL-2 cytokine family receptors. Blocking common gamma-chain transduction activity results in a potent and specific immunosuppressive activity. With respect to the interesting and unexploited immunomodulating properties of this family of compounds we initiated a medicinal chemistry program aimed at finding novel prodigiosin derivatives with improved immunosuppressive activity and lower toxicity. Utilizing an unprecedented and flexible way of assembling the prodigiosin frame, a number of new derivatives have been prepared and tested leading to the choice of 4-benzyloxy-5-[(5-undecyl-2H-pyrrol-2-ylidene)methyl]-2,2′-bi- 1H-pyrrole (PNU-156804, 16) as a lead immunosuppressant.

Lead finding for acetyl cholinesterase inhibitors from natural origin: Structure activity relationship and scope

Acetylcholinesterase (AChE) inhibitors are considered as promising therapeutic agents for the treatment of several neurological disorders such as Alzheimer’s disease (AD), senile dementia, ataxia and myasthenia gravis. There are only few synthetic medicines with adverse effects, available for treatment of cognitive dysfunction and memory loss associated with these diseases. A variety of plants has been reported to possess AChE inhibitory activity and so may be relevant to the treatment of neurodegenerative disorders such as AD. Hence, developing potential AChE inhibitors from botanicals is the need of the day. This review will cover some of the promising acetylcholinesterase inhibitors isolated from plants with proven in vitro and in vivo activities with concern to their structure activity relationship.

Nitro substituted bisindolylmalimide derivatives: Position-dependent emission

A small series of partially alkylated bisindolylmaleimide dyes were prepared containing NO2 groups at the ortho, meta, and para position. The effect of substitution position in the aryl ring on the photophysical properties of the dyes is discussed in detail. The highly electron withdrawing NO2 makes different emission behavior of these dyes. Medium quantum yields of fluorescence in toluene solution are observed for derivative with NO2 substituted in the ortho position of aryl ring. Careful analysis of optimized structure and frontier molecular orbitals (HOMO/LUMO) suggests that the electronic rather than steric effect is controlling non-radiative decay.

Synthesis and applications of heterobifunctional poly(ethylene oxide) oligomers

Poly(ethylene oxide) (PEO) oligomers are employed extensively in pharmaceutical and biomedical arenas mainly due to their excellent physical and biological properties, including solubility in water and organic solvents, lack of toxicity, and absence of immunogenicity. PEO can be chemically modified and reacted with, or adsorbed onto, other molecules and surfaces. Sophisticated applications for PEO have increased the demand for PEO oligomers with tailored functionalities, and heterobifunctional PEOs are often needed. This review discusses the synthesis and applications of heterobifunctional PEO oligomers possessing amine, carboxylate, thiol, and maleimide functional groups.

Self-healing polyurethanes with shape recovery

Two new thermoresponsive self-healing polyurethanes (1DA1T and 1.5DA1T) based on the Diels-Alder (DA) reaction between furan and maleimide moieties are developed that use the shape-memory effect to bring crack faces into intimate contact such that healing can take place. Unlike other self-healing polymers, these polymers do not require external forces to close cracks but rather they use the shape-memory effect to autonomously close the crack. Both polyurethanes have a stable polymer structure and comparable mechanical properties to commercial epoxies. A differential scanning calorimeter is employed to check the glass transition temperature of the polymers as well as the DA and retro-DA (rDA) reaction temperatures. These DA and rDA reactions are confirmed with variable-temperature proton nuclear magnetic resonance. Healing efficiency is calculated using a measurement of the failure load from compact tension testing. The results show that the shape-memory effect can replace external forces to close two crack surfaces and the DA reaction can be repeatedly employed to heal the cracks.
