In this study, hazelnut, pistachio, and apricot kernel shells were ground size of 0–300 µm, 300–600 µm, and 600–850 µm. The cellulose, ash, humidity, and metal contents of these powder particles were chemically analyzed and structural properties were characterized using X-Ray Diffraction (XRD) and Fourier Transform Infrared Spectrometer (FT-IR) analysis. Their composites were fabricated by adding 0%, 10%, 20%, and 30% by weight of these powder particles to the polyester matrix material. The effect of chemical and structural properties of the powder particles on the physical, thermal, and mechanical properties of the composites was analyzed. The XRD analysis revealed that cellulose structure observed in powder particles. The peaks observed in their surface functional structures with FT-IR were mainly caused by cellulose and hemicellulose structures. These structures effected humidity and ash ratios. Nitrogen, carbon, hydrogen, and oxygen elements were seen in the structure. In addition, heavy metals such as Sn, Ca, K, Na, Mg, Fe, Ni, Mn, Cu, Zn, and Si were found. Powder particles added to the polyester material adversely affected the tensile strength of the matrix material. However, powder particles added to the matrix material at low rates had a positive effect on bending and compressive strength.

In this study, we investigated the in vitro antiproliferative activities and performed computational studies of newly synthesized fluorinated isatin-hydrazones. The chemical structures of the synthesized compounds were confirmed by FT-IR, 1D NMR (¹H- and ¹³C NMR and APT), 2D NMR (HETCOR and HMBC), and elemental analysis. All compounds (1-15) were tested in human lung (A549) and liver (HepG2) cancer cell lines for 72 h. The compounds were screened against a healthy embryonic kidney cell line (HEK-293T) under the same conditions to determine their toxic effects. According to the results obtained, one of the compounds, in particular, compound 8 was effective at inhibiting the growth of cancerous cells, and its effects on both cancer cell lines were similar to IC₅₀ values of 42.43 and 48.43 μM for A549 and HepG2, respectively. Compound 8, which was determined to be the best anticancer agent in vitro, was chosen to interact with the target via molecular docking. This selected ligand (compound 8) interacted with the targets 4HJO, 4ASD, 3POZ, and 7TZ7, and docked into the active sites. The docking score, Glide energy, and Glide emodel values were calculated and determined to be lower than those of the reference compound cisplatin. The pharmacokinetic properties, stability, and drug-likeness parameters of all designed compounds were estimated using SwissADME. Finally, the binding affinities of compound 8 for all four targets were calculated using the MM-GBSA method.
