New antitumor compounds from Carya cathayensis was written by Wu, Wei;Bi, Xiu-Li;Cao, Jia-Qing;Zhang, Kai-Qing;Zhao, Yu-Qing. And the article was included in Bioorganic & Medicinal Chemistry Letters in 2012.Category: ethers-buliding-blocks This article mentions the following:
A new lignan (7R,8S,8’R)-4,4′,9-trihydroxy-7,9′-epoxy-8,8′-lignan, and three new phenolics, carayensin-A, carayensin-B, and carayensin-C, together with 13 known compounds were isolated from the shells of Carya cathayensis. Their chem. structures were established mainly by 1D and 2D NMR techniques and mass spectrometry. All the compounds were evaluated for cytotoxicity against several human tumor types including human colorectal cancer cell lines (HCT-116, HT-29), human lung cancer cell line (A549), and human breast cancer cell line (MCF-7). The compounds 1, 5, 6, and 16 are considered to be potential as antitumor agents, which could significantly inhibit the cancer cell growth in a dose-dependent manner. In the experiment, the researchers used many compounds, for example, 3-Hydroxy-5-methoxybenzaldehyde (cas: 57179-35-8Category: ethers-buliding-blocks).
3-Hydroxy-5-methoxybenzaldehyde (cas: 57179-35-8) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. Autoxidation is the spontaneous oxidation of a compound in air. In the presence of oxygen, ethers slowly autoxidize to form hydroperoxides and dialkyl peroxides. If concentrated or heated, these peroxides may explode. To prevent such explosions, ethers should be obtained in small quantities, kept in tightly sealed containers, and used promptly.Category: ethers-buliding-blocks
