   ABSTRACT New methacrylate monomers with carbazole moieties as pendant groups were synthesized by multistep syntheses starting from carbazoles with biphenyl substituents in the aromatic ring. The corresponding polymers were prepared using a free‐radical polymerization. The novel polymers containN‐alkylated carbazoles mono‐ or bi‐substituted with biphenyl groups in the aromatic ring.N‐alkyl chains in polymers vary by length and structure. All new polymers were synthesized to evaluate the structural changes in terms of their effect on the energy profile, thermal, dielectric, and photophysical properties when compared to the parent polymer poly(2‐(9H‐carbazol‐9‐yl)ethyl methacrylate). According to the obtained results, these compounds may be well suited for memory resistor devices. © 2018 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem.2019, 57, 70–76

   Abstract The indolizinium natural product ficuseptine, produced by the tropical fig tree Ficus septica, has been reported to have antibacterial properties. Herein, the synthesis of ficuseptine, ten analogues with differing aryl substituents, and two aryl regioisomers is reported. Despite several previous total syntheses, synthetically prepared ficuseptine has not been subjected to biological testing to confirm its activity. In our hands, ficuseptine was moderately active in Gram-positive B. spizizenii, with an MIC of 32 μg/mL, which was maintained for most aryl substituents. The position of the aryl rings was crucial, however, since regioisomeric ficuseptine analogues, mimicking related natural products, were found to be inactive. Finally, all ficuseptine derivatives were inactive (MIC >128 μg/mL) against Gram-negative E. coli. Understanding these structure–activity relationships (SAR) is helpful for future studies to understand the molecule’s mechanism of action or further develop its antibacterial properties.
