Abstract: In this paper, at first commercially available ZnO nanoparticles were modified with biodegradable nanocellulose through ultrasonic irradiation technique. Then, optically active bionanocomposite (BNCs) membranes composed of polyester (PE) and cellulose/ZnO BNCs are synthesized, as a novel process to enhance gas separation performance. The obtained PE/BNCs were characterized by Fourier transform-infrared spectroscopy, thermogravimetry analysis (TGA), X-ray powder diffraction, field emission-scanning electron microscopy, and transmission electron microscopy (TEM). TGA data indicated an increase thermal stability of the PE/BNCs in compared to the pure polymer. From TEM image of PE/BNCs, it can be found that the surface-modified ZnO with diametric size of less than 40?nm, uniformly dispersed in the obtained PE matrix. The results obtained from gas permeation experiments with a constant pressure setup showed that adding cellulose/ZnO to the polyester membrane structure increased the permeability of the membranes. From biodegradation test observed that the degradation occurred in a faster rate in the presence of cellulose/ZnO in the PE matrix. Graphical Abstract: [Figure not available: see fulltext.].

Endosomal toll-like receptors (TLRs) 7 and 8 recognize viral single-stranded RNAs, a class of imidazoquinoline compounds, 8-oxo-adenosines, 8-aminobenzodiazepines, pyrimidines, and guanosine analogues. Substantial evidence is present linking chronic inflammation mediated specifically by TLR7 to the progression of autoimmunity. We identified a new TLR7/8 dual inhibitor (1) and a TLR8-specific inhibitor (2) based on our previous screen targeting TLR8. Compound 1, bearing a benzanilide scaffold, was found to inhibit TLR7 and TLR8 at low micromolar concentrations. We envisioned making modifications on the benzanilide scaffold of 1 resulting in a class of highly specific TLR7 inhibitors. Our efforts led to the discovery of a new TLR8 inhibitor (CU-115) and identification of a TLR7/8 dual inhibitor (CU-72), bearing a distinct diphenyl ether skeleton, with potential for TLR7 selectivity optimization. Given the role of TLR8 in autoimmunity, we also optimized the potency of 2 and developed a new TLR8 inhibitor bearing a 1,3,4-oxadiazole motif.
