The author of 《Tuning of optical properties of p-phenyl ethenyl-E-furans: A Solvatochromism and Density functional theory》 were Kumar, Naresh; Paramasivam, Mahalingavelar; Kumar, Jagdeep; Gusain, Anamika; Hota, Prasanta Kumar. And the article was published in Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy in 2019. Recommanded Product: 4-Cyanobenzyl bromide The author mentioned the following in the article:

P-Ph ethenyl-E-furans (1-6) with varied electron donor and acceptor substituent (NO2, CN, Cl, H, OCH3, NH2) were synthesized and studied the substituent induced optical properties (dipole moment, transition dipole moment, oscillator strength, optical band gap, hyperpolarizability) using Solvatochromism and D. functional theory. It is shown that furan acts as a weak electron donor in presence of an electron withdrawing p-Ph substituent (NO2, CN, Cl), whereas furan acts as a weak electron acceptor in presence of an electron donating p-Ph substituent (OCH3, NH2). In comparison to ethenylfuran 4, the HOMO-LUMO energy band gap is decreased upon increasing the electron donating or electron withdrawing nature of the Ph ring. Calculation of excited state dipole moment and polarizability of 1-6 in solvent of varying polarity suggest that the nitro and amino compounds (1, 6) exhibit charge transfer excited state, whereas excited state of compounds 3-5 is non-polar in nature. As compared to the ethenylfuran (4), the first hyperpolarizability (β) is increased in presence of a strong electron withdrawing or strong electron donating p-Ph substituent. The higher β value is found for ethenylfuran with p-nitrophenyl and p-amino Ph substitution. Overall, these studies provide useful information in tuning the optical properties of p-Ph substituted heterocyclic ethenyl systems. In the experiment, the researchers used 4-Cyanobenzyl bromide(cas: 17201-43-3Recommanded Product: 4-Cyanobenzyl bromide)

HPLC of Formula: 614-16-4 The article mentions the following:

In the current medical era, spirooxindole motif stands out as a privileged heterospirocyclic scaffold that represents the core for a wide range of bioactive naturally isolated products (such as Strychnofoline and spirotryprostatins A and B) and synthetic compounds Interestingly, no much attention has been paid to develop spirooxindole derivatives with dual antioxidant and anticancer activities. In this context, a series of spirooxindoles 6a-p was examined for their anticancer effect towards HepG2 hepatocellular carcinoma and PC-3 prostate cancer cell lines. Spirooxindole 6a was found to be an efficient anti-proliferative agent towards both HepG2 and PC-3 cells (IC50 = 6.9 and 11.8μM, resp.). Afterwards, spirooxindole 6a was assessed for its apoptosis induction potential in HepG2 cells, where its pro-apoptotic impact was approved via the significant elevation in the Bax/Bcl-2 ratio and the expression levels of caspase-3,. In the experiment, the researchers used many compounds, for example, 3-Oxo-3-phenylpropanenitrile(cas: 614-16-4HPLC of Formula: 614-16-4)
