Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 3393-45-1, is researched, SMILESS is O=C1C=CCCO1, Molecular C5H6O2Journal, Article, Natural Products and Bioprospecting called Chemical Constituents from the Whole Plant of Cuscuta reflexa, Author is Aung, Tin Thu Thu; Xia, Meng-Yuan; Hein, Pyae Phyo; Tang, Rong; Zhang, Dong-Dong; Yang, Jun; Yang, Xue-Fei; Hu, Dong-Bao; Wang, Yue-Hu, the main research direction is chem constituent plant cuscuta reflexa; 2H-pyran-2-one glucosides; Cuscuta reflexa; Platelet aggregation; Porcine pancreatic lipase; Steroidal glucosides.Formula: C5H6O2.
Two new 2H-pyran-2-one glucosides, cuscutarosides A (1) and B (2), and one new steroidal glucoside, 7β-methoxy-β-sitosterol 3-O-β-glucopyranoside (3), together with 12 known compounds (4-15) were isolated from the whole plant of Cuscuta reflexa (Convolvulaceae) collected from Myanmar. The chem. structures of these new compounds were elucidated based on extensive spectroscopic anal. The antiobesity activity of these isolates was evaluated using porcine pancreatic lipase (PPL), and the antiplatelet aggregation activity was screened using rabbit platelets induced by thrombin, platelet-activating factor (PAF), arachidonate (AA), or collagen. 7β-Methoxy-β-sitosterol 3-O-β-glucopyranoside (3) showed weak PPL inhibitory activity. Cuscutaroside A (1), its acetylated derivative (1a), and scrophenoside B (8) showed weak inhibitory activity against rabbit platelet aggregation induced by collagen. Compound 1a also showed inhibitory activity against rabbit platelet aggregation induced by AA.
Compounds in my other articles are similar to this one(5,6-Dihydro-2H-pyran-2-one)Formula: C5H6O2, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
