Abdul Amin, Sk.; Adhikari, Nilanjan; Jha, Tarun; Gayen, Shovanlal published an article in 2016, the title of the article was Exploring structural requirements of unconventional Knoevenagel-type indole derivatives as anticancer agents through comparative QSAR modeling approaches.COA of Formula: C12H7N3 And the article contains the following content:

An indole ring system is considered as a versatile scaffold in the pharmaceutical field. In this article, comparative QSAR modeling (2D-QSAR, 3D-QSAR; kNN-MFA and Co-MSIA) was performed on some Knoevenagel-type cytotoxic indole derivatives to understand the structural requirements for the cytotoxic property of these compounds The 2D-QSAR model was statistically significant and imparted high predictive ability (nTrain = 30; R = 0.917; RA2=0.801; cRp2=0.757; Q2 = 0.722; nTest = 9; Rpred2=0.799). A statistically significant 3D-QSAR kNN-MFA model (both with stepwise forward and simulated annealing model selection method) as well as a 3D-QSAR Co-MSIA model was developed to identify the key chem. features associated with enhancing the cytotoxic activities of these indoles. The results suggest that the presence of bulky group in R position can cause better cytotoxic activities. Consequently, substitution with cyano group at X portion and cyano/ester/keto/sulfonyl features at Y position is favorable for the cytotoxicity. However, hydrophobic features in R’ region are unfavorable for the biol. activity. The chem. and structural features identified from the study may provide important avenues to modulate the structure of these indoles to a desirable biol. end point. The experimental process involved the reaction of 2-((1H-Indol-3-yl)methylene)malononitrile(cas: 75629-62-8).COA of Formula: C12H7N3

Turpaev, Kyril; Ermolenko, Mikhail; Cresteil, Thierry; Drapier, Jean Claude published an article in 2011, the title of the article was Benzylidenemalononitrile compounds as activators of cell resistance to oxidative stress and modulators of multiple signaling pathways. A structure-activity relationship study.Reference of 2-((1H-Indol-3-yl)methylene)malononitrile And the article contains the following content:

Benzylidenemalononitrile (BMN) tyrphostins are well known as potent tyrosine kinase inhibitors. Moreover, in recent years it has been recognized that members of the tyrphostin family possess addnl. biol. activities independent of their ability to inhibit protein tyrosine kinases. In this study, we examined the relationship between the structure of 49 BMNs and related compounds, and their capacity to induce heme oxygenase 1 (HO-1) gene expression in U937 human monocytic cells, to activate upstream signaling pathways and to protect cells against menadione-induced oxidative stress. It was found that the electron-withdrawing (NO2, CN, halogen) groups in BMN mols. and double meta-MeO substituents increased the HO-1 gene induction, while the electron-donating groups in ortho/para position (OH, MeO and N-morpholino) significantly decreased it. The magnitude of activation of c-Jun, Nrf2, p38 MAPK, and p70S6K correlated with specific substitution patterns in the BMN structure. BMN-dependent maximal up-regulation of HO-1 required parallel increase in Nrf2 and phospho-c-Jun cellular levels. Liquid chromatog. mass spectrometry (LC-MS) anal. revealed that BMNs can generate conjugates with one or two glutathione equivalent(s). This study supports the hypothesis that BMNs induce the expression of protective genes by alkylating sensitive cysteine residues of regulatory factors.

Dawood, Dina H.; Srour, Aladdin M.; Saleh, Dalia O.; Huff, Kelley J.; Greco, Francesca; Osborn, Helen M. I. published an article in 2021, the title of the article was New pyridine and chromene scaffolds as potent vasorelaxant and anticancer agents.Formula: C12H7N3 And the article contains the following content:

Based on studies that have reported the association between cancer and cardiovascular diseases, new series of pyridine- (3a-o) and/or chromene- (4a-e) carbonitrile analogus were designed, synthesized and screened for their vasodilation and cytotoxic properties. The majority of the new chem. entities demonstrated significant vasodilation efficacies, compounds 3a, 3h, 3j, 3m, 3o, 4d and 4e exhibited the most promising potency with IC50 = 437.9, 481.0, 484.5, 444.8, 312.1, 427.6 and 417.2 μM, resp., exceeding prazosin hydrochloride (IC50 = 487.3 μM). Compounds 3b-e, 3k and 3l also, revealed moderate vasodilation activity with IC50 values ranging from 489.7 to 584.5 μM. In addition, the anti-proliferative activity evaluation of the exptl. compounds at 10 μM on the MCF-7 and MDA-MB 231 breast cancer cell lines illustrated the excellent anti-proliferative properties of derivatives 3d, 3g and 3i. Compound 3d was the most potent analog with IC50 = 4.55 ±0.88 and 9.87 ±0.89 μM against MCF-7 and MDA-MB 231, resp. Moreover, compound 3d stimulated apoptosis and cell cycle arrest at the S phase in MCF-7 cells in addition to its capability in accumulation of cells in pre-G1 phase and activating caspase-3. Furthermore, the mol. docking of 3d was performed to discover the binding modes within the active site of caspase-3. 3d, as the only common bi-functional agent among the tested hits, demonstrated that new pyridine-3-carbonitrile derivatives bearing cycloheptyl ring systems offer potential as new therapeutic candidates with combined vasodilation and anticancer properties.

Lv, Yongjun; Guo, Yong; Xu, Jian; Shao, Shijun published an article in 2011, the title of the article was Simple indole-based colorimetric sensors with electron-withdrawing chromophores: Tuning selectivity in anion sensing.Related Products of 75629-62-8 And the article contains the following content:

Three simple colorimetric anion sensors containing anthrone, 1,3-indanedione, and malononitrile as signaling chromophores and an indole binding site were designed and synthesized. The introduction of electron-withdrawing groups can not only provide chromogenic signal output, but also tune the sensitivity and selectivity of indole-based anion sensors by electron push-pull features. Their anion binding and sensing properties were studied in detail by dramatic color changes, UV-visible absorption, and 1H NMR. As results revealed, sensor I showed high selectivity for F- over AcO- and H2PO4- with a distinct change in color due to the deprotonation of indole NH group. The excellent selectivity of I for F- can be attributed to the fitness in the acidity of its NH-group, which is tuned to be able to distinguish the subtle difference in the affinity of F-, AcO-, and H2PO4- to NH proton.

Chowhan, Bushra; Gupta, Monika; Sharma, Neha published an article in 2019, the title of the article was Designing of Ultrafine PdNPs Immobilized Pyridinic-N Doped Carbon and Evaluation of its Catalytic Potential for Konevenagel Condensation, Synthesis of 4H-pyran Derivatives and Nitroreduction.Application In Synthesis of 2-((1H-Indol-3-yl)methylene)malononitrile And the article contains the following content:

The desiging of ultrafine Pd-based nanocatalyst containing N-doped carbon structure (Pd@NC) was reported. The material was prepared by direct dehydration at 120 °C followed by mixing and heating with a dopant (ammonium oxalate) at 150 °C in a furnace. The Pd@NC nanocatalyst containing electron-rich pyridinic-N doped carbon structure, was thoroughly characterized by various techniques namely SEM, EDX, TEM, FTIR, ICP-AES, XRD, XPS, TGA and Raman spectroscopy. The utility of the Pd@NC nanocatalyst was explored for base-free Knoevenagel condensation and 4H-pyran derivatives and also in the reduction of nitroarenes under mild and greener conditions. Further, the optical property was explored using photoluminescence spectroscopy and band gap was also calculated The heterogeneous nature and stability of the catalyst facilitated by its ease of separation for long-term performance and recycling studies showed that catalyst was robust and remained active upto six recycling experiments Also, the leaching of metal was confirmed by ICP-AES. The superiority of the catalyst was attributed to the metal support interaction (MSI) between metallic palladium and pyridinic-N doped carbon to acquire excellent catalytic activity and changing the reducing nature of NaBH4 towards nitro functionality. The MSI between pyridinic-N dopant on the carbon structure and PdNPs produces highly active sites for catalytic performance under mild conditions.
