de Vasconcelos, Alana published the artcile2,4-Thiazolidinedione as Precursor to the Synthesis of Compounds with Anti-glioma Activities in C6 and GL261 Cells, Application of 3-Chlorobenzylchloride, the publication is Medicinal Chemistry (Sharjah, United Arab Emirates) (2021), 17(6), 601-610, database is CAplus and MEDLINE.

Thiazolidinediones (TZDs) represent an important class of heterocyclic compounds that have versatile biol. activities, including anticancer activity. Glioma is one of the most common primary brain tumors, and it is responsible for most of the deaths caused by primary brain tumors. In the present work, 2,4-thiazolidinediones were synthesized via a multicomponent microwave one-pot procedure. The cytotoxicity of compounds was analyzed in vitro using rat (C6) and mouse (GL261) glioblastoma cell lines and primary cultures of astrocytes. This study aims to synthesize and characterize 2,4-thiazolidinediones and evaluate their antitumor activity. TZDs were synthesized from three components: 2,4-thiazolidinedione, arene-aldehydes, and aryl chlorides. The reactions were carried out inside a microwave and monitored using thinlayer chromatog. (TLC). Compounds were identified and characterized using gas chromatog. coupled to mass spectrometry (CG-MS) and hydrogen (¹H-NMR) and carbon NMR spectroscopy (¹³C-NMR). The antitumor activity was analyzed using the 3-(4,5- dimethyl)-2,5-diphenyltetrazolium bromide (MTT) reduction test, in which cell viability was verified in the primary cultures of astrocytes and in rat and mouse glioblastoma cells exposed to the synthesized compounds The cytotoxicity of all derivatives was analyzed at the 100 μM concentration, both in astrocytes and in the mouse and rat glioblastoma cell lines. The compounds that showed the best results, 4CI and 4DI, were also tested at concentrations 25, 50, 100, 175, and 250 μM to obtain the IC₅₀. Seventeen TZD derivatives were easily obtained through one-pot reactions in 40 min with yields ranging from 12% to 49%. All compounds were cytotoxic to both glioblastoma cell lines without being toxic to the astrocyte primary cell line at 100 μM, thus demonstrating a selective activity. Compounds 4CI and 4DI showed the best results in the C6 cells: IC₅₀ of 28.51 μM and 54.26 μM, resp. The compounds were not cytotoxic in astrocyte culture, demonstrating selectivity for malignant cells. Changes in both rings are important for anti-glioma activity in the cell lines tested. TZD 4CI had the best anti-glioma activity.

Ke, Jie published the artcileHexafluoroisopropanol-Enabled Copper-Catalyzed Asymmetric Halogenation of Cyclic Diaryliodoniums for the Synthesis of Axially Chiral 2,2′-Dihalobiaryls, Name: 4-Chloro-2-methylphenylboronic acid, the publication is Organic Letters (2021), 23(2), 329-333, database is CAplus and MEDLINE.

An efficient asym. halogenation of cyclic diaryliodonium salts was demonstrated, which gave access to a wide range of axially chiral 2,2′-dihalobiaryls in good to excellent yields and with excellent enantioselectivities. The use of CuX with chiral bisoxazoline ligand and tetrabutylammonium halides in the unique solvent of hexafluoroisopropanol (HFIP) led to the best results in the process. The axially chiral 2,2′-dihalobiaryls was transformed into a number of enantiopure chiral ligands that was potentially useful in asym. catalysis.

Ren, Jing-Ling published the artcileLimonoids containing a C₁-O-C₂₉ moiety: isolation, structural modification, and antiviral activity, Quality Control of 6313-54-8, the publication is Marine Drugs (2018), 16(11), 434, database is CAplus and MEDLINE.

Five new limonoids named thaigranatins A-E (1-5), containing a C1-O-C29 moiety, were isolated from seeds of the Thai Xylocarpus granatum, collected at the mangrove swamp of Trang Province, together with the known limonoid, granatumin L (6). The structures of these compounds were established by HR-ESIMS and extensive NMR spectroscopic data. The absolute configuration of 1 was unequivocally determined by single-crystal X-ray diffraction anal., conducted with Cu Kα radiation; whereas that of 2 or 6 was established to be the same as that of 1 by the similarity of their electronic CD (ECD) spectra. In view of the marked antiviral activity of 6, its structure was modified via hydrolysis with alk. KOH, esterification with diazomethane and various organic acids, and oximization with hydroxyamine. Finally, 18 derivatives, viz. 7-10, 8a-8i, 9a-9b, and 10a-10c, were obtained. In vitro antiviral activities of these derivatives against human immunodeficiency virus 1 (HIV-1) and influenza A virus (IAV) were evaluated. Most notably, 8i exhibited marked inhibitory activity against HIV-1 with an IC50 value of 15.98 ± 6.87 μM and a CC50 value greater than 100.0 μM; whereas 10b showed significant inhibitory activity against IAV with an IC50 value of 14.02 ± 3.54 μM and a CC50 value greater than 100.0 μM.
