Bec, Anja; Hok, Lucija; Persoons, Leentje; Vanstreels, Els; Daelemans, Dirk; Vianello, Robert; Hranjec, Marijana published an article in 2021, the title of the article was Synthesis, Computational Analysis, and Antiproliferative Activity of Novel Benzimidazole Acrylonitriles as Tubulin Polymerization Inhibitors: Part 2.Reference of 3-Chloro-4-nitrobenzonitrile And the article contains the following content:

Classical linear and microwave-assisted synthesis methods was used to prepare novel N-substituted, benzimidazole-derived acrylonitriles I [R1 = H, cyano; R2 = Me, iso-Bu, Ph, etc.; R3 = H, 2-methoxy, 3,4,5-trimethoxy, etc.] with antiproliferative activity against several cancer cells in vitro. The most potent systems showed pronounced activity against all tested hematol. cancer cell lines, with favorable selectivity towards normal cells. The selection of lead compounds was also tested in vitro for tubulin polymerization inhibition as a possible mechanism of biol. action. A combination of docking and mol. dynamics simulations confirmed the suitability of the employed organic skeleton for the design of antitumor drugs and demonstrated that their biol. activity relies on binding to the colchicine binding site in tubulin. In addition, it also underlined that higher tubulin affinities are linked with (i) bulkier alkyl and aryl moieties on the benzimidazole nitrogen and (ii) electron-donating substituents on the Ph group that allow deeper entrance into the hydrophobic pocket within the tubulin’s β-subunit, consisting of Leu255, Leu248, Met259, Ala354, and Ile378 residues. The experimental process involved the reaction of 3-Chloro-4-nitrobenzonitrile(cas: 34662-29-8).Reference of 3-Chloro-4-nitrobenzonitrile

Luisa; Oliveira-Campos, Ana M. F.; Unzeta, Mercedes; Marco-Contelles, Jose; Majekova, Magdalena; Ramsay, Rona R.; Carreiras, M. Carmo published an article.Computed Properties of 75629-62-8 The title of the article was Synthesis, biological evaluation, and molecular modeling of nitrile-containing compounds: Exploring multiple activities as anti-Alzheimer agents. And the article contained the following:

Based on the monoamine oxidase (MAO) inhibition properties of aminoheterocycles with a carbonitrile group we have carried out a systematic exploration to discover new classes of carbonitriles endowed with dual MAO and AChE inhibitory activities, and Aβ anti-aggregating properties. Eighty-three nitrile-containing compounds, 13 of which are new, were synthesized and evaluated. In vitro screening revealed that 31, a new compound, presented the best lead for trifunctional inhibition against MAO A (0.34μM), MAO B (0.26μM), and AChE (52μM), while 32 exhibited a lead for selective MAO A (0.12μM) inhibition coupled to AChE (48μM) inhibition. Computational anal. revealed that the malononitrile group can find an advantageous position with the aromatic cleft and FAD of MAO A or MAO B. However, the total binding energy can be handicapped by an internal penalty caused by twisting of the ligand mol. and subsequent disruption of the conjugation (32 in MAO B compared to the conjugated 31). Conjugation is also important for AChE as well as the hydrophilic character of malononitrile that allows this group to be in close contact with the aqueous environment as seen for 83. Although the effect of 31 and 32 against Aβ1-42, was very weak, the effect of 63 and 65, and of the new compound 75, indicated that these compounds were able to disaggregate Aβ1-42 fibrils. The most effective was 63, a (phenylhydrazinylidene)propanedinitrile derivative that also inhibited MAO A (1.65μM), making it a potential lead for Alzheimer’s disease application. The experimental process involved the reaction of 2-((1H-Indol-3-yl)methylene)malononitrile(cas: 75629-62-8).Computed Properties of 75629-62-8

And the article contained the following:

The first discrete seven-membered cyclic zinc(II) complex catalyzed room temperature Knoevenagel condensation reactions, and the synthesis of perimidine derivatives is reported under mild reaction conditions. The cyclic zinc(II) complex [(L)ZnBr2] (1) was isolated from the reaction between 1-(2-hydroxyethyl)-3-isopropyl-benzimidazol-2-thione (L, 2) and ZnBr2 (3). Complex 1 was characterized by different analytic techniques such as FTIR, CHNS, TGA, NMR, and SCXRD. The mononuclear zinc(II) complex 1 was used as a catalyst for Knoevenagel condensation reactions to isolate twenty different substituted methylene malononitriles with excellent yield. Besides, the zinc(II) thione complex 1 was used for the synthesis of 2,4-dihydroperimidine derivatives in a highly efficient manner. Catalyst 1 depicted wide substrate scopes. Overall, twenty different substituted methylene malononitriles and nine different perimidine derivatives were synthesized using catalyst 1 at room temperature The present study features a mild and fast synthetic approach along with excellent functional group tolerance.
