2,3-Dimethoxy-5-methylcyclohexa-2,5-diene-1,4-dione (cas: 605-94-7) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. But ether is more polar than alkenes. Ethers feature bent C閳ユ彊閳ユ弲 linkages. In dimethyl ether, the bond angle is 111鎺?and C閳ユ彊 distances are 141 pm. The barrier to rotation about the C閳ユ彊 bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3.Recommanded Product: 605-94-7

A. camphorata is a rare and precious traditional food and medicine for improving health-related conditions in Taiwan. The phytochem. research of the mushroom led to the isolation of a new naphthalenecarboxaldehyde, named as 1-naphthalenecarboxaldehyde,3,4,4a,5,6,7,8,8a-octahydro-2-(hydroxymethyl)-5,5,8a-trimethyl (1). Meanwhile, 7 other known compounds, nerolidol (2), cadinol (3), herbarulide (4), 3灏?hydroxy-5a,8a-epidioxyergosta-6,22-diene (5), ergosta-7,22-diene-3,6-dione (6) 2,3-dimethoxy-5-methyl-p-benzoquinone (7) and 灏?sitosterol (8), were also obtained from A. camphorata for the 1st time except compound 8. The new compound was elucidated by 2D NMR techniques (COSY, HMBC, HSQC, NOESY) and HRMS, while the known compounds were deduced by comparing 1H NMR and 13C NMR data with the literature. HepG2 cell toxicity screening was conducted and the results demonstrated that only compounds 7 and 8 exhibited significant cytotoxicity to HepG2 cells at a concentration of 50 娓璯/mL. In the experiment, the researchers used many compounds, for example, 2,3-Dimethoxy-5-methylcyclohexa-2,5-diene-1,4-dione (cas: 605-94-7Recommanded Product: 605-94-7).
