- Novel β?hydroxy ketones: Synthesis, spectroscopic characterization, molecular docking, and anticancer activity studies
-
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.

- Formation and Disproportionation of Xanthenols to Xanthenes and Xanthones and Their Use in Synthesis
-
A facile and versatile strategy employing TiCl4-mediated cyclization followed by a Cannizzaro reaction has been developed for the synthesis of various xanthene derivatives. The reaction proceeded smoothly to afford both xanthenes/xanthones or their sulfur derivatives and tolerated a wide range of electronically diverse substrates. Using this methodology, pranoprofen was synthesized in three steps in 59% overall yield from commercially available starting materials.

- Synthesis of new thioxanthenes by organocatalytic intramolecular Friedel–Crafts reaction
-
An efficient organocatalytic route has been developed to synthesize novel substituted thioxanthenes (2a–2v) starting from diaryl thioether alcohols (1a–1v) using the intramolecular Friedel–Crafts reaction. The starting materials were obtained in two stage

- Preparation of functionalized aryl magnesium reagents by the addition of magnesium aryl thiolates and amides to arynes
-
(Chemical Equation Presented) Reactive arynes, which are readily generated by the reaction of ortho-iocloarylsulfonates with iPrMgCl, undergo the smooth addition of various magnesium nucleophiles like magnesium thiolates, selenides, and amides. In all cases the resulting functionalized aryl magnesium species can be trapped by an electrophile leading to highly functionalized aromatic compounds (see scheme).

- A concise synthesis of ortho-substituted aryl-acrylamides - Potent activators of soluble guanylyl cyclase
-
Horner-Emmons reaction of phosphonate amides with aldehydes leads to generation of o-substituted aryl-acrylamides. These compounds have been shown to be useful to quickly establish structure-activity relationships (SAR) for soluble guanylyl cyclase (sGC)
