Synthesis and biological evaluation of isatin derivatives containing 1,3,4-thiadiazole as potent a-glucosidase inhibitors was written by Zhao, Xuelian;Zhan, Xuehui;Zhang, Huilin;Wan, Yichao;Yang, Huizhong;Wang, Yutian;Chen, Yanda;Xie, Wenlin. And the article was included in Bioorganic & Medicinal Chemistry Letters in 2021.Electric Literature of C8H9Cl This article mentions the following:

A series of isatin derivatives containing 1,3,4-thiadiazole derivatives I [R = 2-F, 3-CN, 4-Cl, etc.] were designed and synthesized. All newly synthesized compounds I were evaluated for their α-glucosidase inhibitory activity with resveratrol as pos. control in-vitro. Except for compounds I [R = 2-CN, 3-CN], all of the compounds I showed a potent inhibitory activity against α-glucosidase with IC₅₀ values in the range of 3.12 ± 1.25 to 45.95 ± 1.26μM and the purity of these compounds were greater than 95%. The IC₅₀ values were being compared to the standard resveratrol (IC₅₀ = 22.00 ± 1.15μM) and it was found that compounds I [R = H, 2-F, 2-Cl, 3-Cl, 4-Cl, 2-Br] were found to be more active than resveratrol. Specifically,I [R = 4-Cl] exhibited the most potent α-glucosidase inhibitory activity with IC₅₀ value of 3.12 ± 1.25μM. The kinetic anal. revealed that compound I [R = 4-Cl] was noncompetitive inhibitor. Structure activity relationship was established for all compounds I. Furthermore, the binding interactions of compound I [R = 4-Cl] with the active site of α-glucosidase were confirmed through mol. docking. This study was identified a new class of potent α-glucosidase inhibitors for further investigation. In the experiment, the researchers used many compounds, for example, 1-(Chloromethyl)-3-methylbenzene (cas: 620-19-9Electric Literature of C8H9Cl).

1-(Chloromethyl)-3-methylbenzene (cas: 620-19-9) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Electric Literature of C8H9Cl

Thiosemicarbazide, a fragment with promising indolamine-2,3-dioxygenase (IDO) inhibition properties was written by Serra, Silvia;Moineaux, Laurence;Vancraeynest, Christelle;Masereel, Bernard;Wouters, Johan;Pochet, Lionel;Frederick, Raphael. And the article was included in European Journal of Medicinal Chemistry in 2014.Product Details of 6590-96-1 This article mentions the following:

With the aim to explore the interest of the thiosemicarbazide scaffold for the inhibition of the indoleamine 2,3-dioxygenase (IDO), a promising therapeutic target for anticancer immunotherapy, a series of 32 phenylthiosemicarbazide derivatives was prepared and their IDO inhibition evaluated. Our study demonstrated that among these derivatives, compound I characterized with a 4-cyanophenyl group on the thiosemicarbazide was the more potent IDO inhibitor in this series being endowed with an IC₅₀ of 1.2 μM. The SAR depicted showed that substitution in the 3- and 4-position relative to the phenylthiosemicarbazide are very promising whereas substitution in the 2-position always leads to less potent or inactive derivatives In fact, the study highlighted a novel interesting scaffold for IDO inhibition for further development. In the experiment, the researchers used many compounds, for example, 2,4-Dichlorophenylisothiocyanate (cas: 6590-96-1Product Details of 6590-96-1).

And the article was included in Angewandte Chemie, International Edition in 2015.Category: chlorides-buliding-blocks This article mentions the following:

The longitudinal extension of cycloparaphenylenes (CPP) towards ultrashort carbon nanotubes (CNTs) is essential for the solution based bottom-up synthesis of CNTs. Herein, the longitudinal extension of the CPP skeleton by the introduction of hexaphenylbenzene units towards polyarylated [n]CPPs is described. Further, the applicability of the Scholl reaction to selectively form graphenic sidewalls is demonstrated. The ring size and substitution patterns of the polyarylated [n]CPPs were varied to overcome strain-induced side reactions during the oxidative cyclodehydrogenation and cyclic para-hexa-peri-hexabenzocoronene trimers ([3]CHBCs) were selectively obtained. This concept is envisioned as an access to ultrashort carbon nanotubes subject to the condition that further benzene rings with the right connectivity will be inserted. In the experiment, the researchers used many compounds, for example, 5-Bromo-2-chloro-m-xylene (cas: 206559-40-2Category: chlorides-buliding-blocks).
