Resistance phenomena during chemotherapy of tumor has been severely hampering the applications of chemotherapeutics. Due to advantage of drug repurposing, discovery of new chemosensitizers based on approved drugs is an effect strategy to find new candidates. Herein, we found antidepressant drug – sertraline, could sensitize drug-resistant gastric cancer cell (SGC-7901/DDP) with the IC50 value of 18.73 μM. To understand the structure–activity relationship and improve the activity, 30 derivatives were synthesized and evaluated. The IC50 value of the best compound was improved to 5.2 μM. Moreover, we found apoptosis induction and cell cycle arrest was the reason for the cell death of the drug-resistant cells after treatment of sertraline and derivatives, and PI3K/Akt/mTOR pathway was involved.

Paragraph 0048-0049, (2021/04/17)
The structural formula of the sertraline side chain amino structure derivative is shown as a formula I or a formula II, wherein R1 is H or cyclopropanyl, and R2 is selected from alkyl, naphthyl, alkylamine, cyclopropanyl, phenyl, or phenyl of which the No.3 position and/or the No.4 position is substituted by alkyl, methoxyalkyl, haloalkyl and halogen; and R3 is a hydrogen group or a 1-halogenated alkyl group. The invention also provides a preparation method of the sertraline derivative and application of the sertraline derivative in preparation of a medicine for treating gastric cancer. The sertraline derivative provided by the invention has an obvious sensitization effect on drug-resistant gastric cancer cells.

A titanium(IV)-mediated ring-opening/dehydroxylative cross-coupling of diaryl-substituted methanols with a cyclopropanol derivative was developed. The reactions proceeded efficiently to provide synthetically useful γ,γ-diaryl esters in moderate to good yields, which could be applied to the functionalization of complex molecules derived from bioactive fenofibrate and isoxepac and the synthesis of a precursor of Zoloft.

The content of the impurity 4-(2,3-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone in the obtained product is less than 0.1%. The invention also relates to a method for preparing the isomer impurity 4-(2,3-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone from the mother solution.
Nickel-Catalyzed α-Carbonylalkylarylation of Vinylarenes: Expedient Access to γ,γ-Diarylcarbonyl and Aryltetralone Derivatives
Dhungana, Roshan K.,Giri, Ramesh,Khanal, Namrata,Shekhar, K. C.
, p. 8047 - 8051 (2020/04/30)
We report a Ni-catalyzed regioselective α-carbonylalkylarylation of vinylarenes with α-halocarbonyl compounds and arylzinc reagents. The reaction works with primary, secondary, and tertiary α-halocarbonyl molecules, and electronically varied arylzinc reagents. The reaction generates γ,γ-diarylcarbonyl derivatives with α-secondary, tertiary, and quaternary carbon centers. The products can be readily converted to aryltetralones, including a precursor to Zoloft, an antidepressant drug.

Towards assembling of diarylmethine unit present in biologically important molecules, we have developed a new Weinreb Amide (WA) based building block derived from glycolic acid. The WA functionality present in this building block permits the sequential addition of various arylmagnesium bromide reagents in a controlled manner that enables assembly of a diarylmethine unit. The developed synthetic route provides easy access to important diarylethenes and α,α-diarylethylene glycols. The synthesized α,α-diarylethylene glycols provide access to synthetically important symmetrical and unsymmetrical α,α-diaryl acetaldehydes as valuable intermediates.
Synthesis of 1-Aryltetralins and 1-Arylnaphthalenes via (4 + 2) Annulation of β-Ketosulfones with Styryl Bromides
Chang, Meng-Yang,Cheng, Yu-Chieh
, p. 1682 - 1685 (2016/04/26)
A novel route has been developed for the synthesis of various substituted 1-aryltetralins 6 and 1-arylnaphthalenes 8 via (1) K2CO3-mediated α-styrylation of β-ketosulfones 3 with bromostyryl bromides 4 and (2) stereocontrolled NaBH4-promoted reduction of the resulting γ-alkenones 5, followed by BF3·OEt2-catalyzed intramolecular annulation of the corresponding γ-alkenols 7 under rt/5 h and reflux/10 h conditions, respectively. The key structures of 6 and 8 were confirmed by X-ray crystallographic analysis. A plausible mechanism has been proposed.

A flow chemistry process for the Oppenauer oxidation of benzylic secondary alcohols using partially hydrated zirconium oxide and a simple carbonyl containing oxidant such as acetone, cyclohexanone, and neopentanal is reported. The heterogeneous oxidative system could be applied to a wide range of functionalized alcohol substrates, allowing clean and fast delivery of ketone products within a few minutes between 40 and 100 C.
