Properties of rosin-based waterborne polyurethanes/cellulose nanocrystals composites

Polymers from renewable biomass are viable supplements for synthetic polymers. In this study, cellulose nanocrystals (CNs) were used as nanofillers to improve properties of rosin-based waterborne polyurethanes (RWPU). The morphology, structure, thermal, and mechanical properties of the RWPU/CNs nanocomposites were investigated. It demonstrated that CNs were compatible with RWPU and dispersed homogeneously in the polymer matrix. CNs as nanofillers improved tensile strength of RWPU significantly. Tensile strength of RWPU/CNs composite films increased from 28.2 to 52.3 MPa with increasing CNs amount from 0 to 20 wt%. Moreover, the thermal stability of RWPU was also improved by CNs and the glass transition temperature of RWPU/CNs decreased comparing with RWPU. This work provided a novel pathway for preparation of biomass-based WPU with excellent properties from cellulose and rosin.

Synthesis and antiviral activity of maleopimaric and quinopimaric acids' derivatives

A series of maleopimaric and quinopimaric acids' derivatives modified in the E-ring, at the carbonyl- and carboxyl-groups were synthesized and evaluated for their activity in vitro against respiratory viruses (influenza; rhinovirus; adenovirus; and SARS), papilloma virus, and hepatitis B and C viruses. The antiviral screening of levopimaric acid diene adducts derivatives was carried out with minimal effect on SARS and influenza type B viruses. Excellent antiviral activity of the ozonolysis product of maleopimaric acid and dihydroquinopimaric methyl-(2-methoxycarbonyl)ethylene amide was found toward papilloma virus (HPV-11 strain) with the selectivity index of SI 30 and 20, respectively. Methyl (2-methoxycarbonyl)ethylene-, 1β-hydroxy-5′-kaprolaktamo- and 4β-hydroxy-4α,14α-epoxy-13(15)-ene-dihydroquinopimaric acid derivatives have also shown activity against replication of HCV nucleic acid and low toxicity.

SYNTHESE AB-TRANS-ANELLIERTER DERIVATE DES TRICYCLISCHEN DITERPENS PLEUROMUTILIN DURCH INTRAMOLEKULARE 1,5-HYDRID-VERSCHIEBUNG

The Diterpene Pleuromutilin(1) reacts with orthoformicacid-trimethylester at room temperature almost quantitatively to give the 11-keto-3-methylester 2 with AB-trans-configuration.This conversion is shown to occur through a 1,5-hydride-shift between C3 and C11.Treatment of 2 with Lewis acid (ZnCl2) initiated a retro-1,5-hydride-shift which resulted in the formation of Pleuromutilin(1).Mechanistic aspects and structure assignments, which are based on chemical and spectroscopic ((1)H- and (13)C-NMR) data are discussed.
