In this study, a series of novel β?hydroxy ketone derivatives 3a-o were designed, synthesized, and evaluated for their anticancer activity. The structure of these compounds were characterized by IR, 1H and 13C NMR, mass spectrometry and elemental analysis methods. All the synthesized compounds were screened for anticancer activity against MCF-7 and U87 cells. Among them, compound 3l was appeared to be the most potent compound on both cancer cells; and IC50 dose was determined as 145 μM for MCF-7 cells and 6,6 μM for U87 cells. DNA ladder and Annexin V apoptotic marker tests were used and as a result, 3l caused the initiation of apoptosis on U87 cells. VDAC protein expression increased dramatically after U87 glioblastoma brain cancer cells were treated with compound 3l Additionally, the molecular modeling of these compounds was studied in FLT3 receptor, Estrogen receptor, and PARP2 receptor for the treatment of Acute Myeloid Leukemia (AML), breast cancer, and Glioblastoma (GBM) respectively. Their binding motifs and drug-like properties were investigated, and the results are highlighted in the discussion. Based on the results, compound 3l may have a potential drug candidate profile that can reverse the drug resistance profile.

NiFe2O4 magnetic nanoparticles (MNPs) were synthesized, characterized and applied as an air-stable, inexpensive and magnetically separable nanocatalyst for the synthesis of structurally diverse sulfides. Efficient methodologies were developed for the synthesis of unsymmetric diaryl sulfides via odourless and one-pot reactions of triphenyltin chloride/S8 or arylboronic acid/S8 as thiolating agents with aryl halides or nitroarenes as starting materials in the presence of base (K2CO3 or NaOH) and NiFe2O4 MNPs as a catalyst in water or poly (ethylene glycol) as solvent at 80–110?°C. Free from ligand and the unpleasant smell of thiols and with the use of magnetically reusable nanocatalyst, green solvents and commercially available and cheap sulfur source and starting materials, these methods are more eco-friendly and practical than available protocols for the synthesis of sulfides.
Metal-free oxidative coupling: Xanthone formation via direct annulation of 2-aryloxybenzaldehyde using tetrabutylammonium bromide as a promoter in aqueous medium

A metal-free intramolecular annulation of 2-aryloxybenzaldehydes to xanthones is disclosed, which proceeds through the direct oxidative coupling of an aldehyde C-H bond and aromatic C-H bonds using tetrabutylammonium bromide (TBAB) as a promoter in aqueous medium. This strategy works smoothly in the presence of both electron-donating and electron-withdrawing groups, and displays good tolerance towards catalytically reactive substituents, thus promising further functionalizations of xanthone products.
