Teicoplanin, antibiotics from Actinoplanes teichomyceticus nov. sp. V. Aromatic constituents.
Oxidative and hydrolytic degradation reactions were carried out on teicoplanin in order to characterize the aromatic portion of the molecule and relate it to the other members of the class of glycopeptide antibiotics. Seven aromatic rings, obtained as triphenyl ether, diphenyl ether, and diphenyl moieties after oxidation nd hydrolysis of teicoplanin, were identified. They are present in teicopl...
متن کاملTyrosinase, Acetyl- and Butyryl-Cholinesterase Inhibitory Activity of Stachys lavandulifolia Vahl (Lamiaceae) and Its Major Constituents
The n-hexane (HE), dichloromethane (DC), methanol (ME), ethanol 70% (ET), and methanol with Soxlhet apparatus (MS) extracts of Stachys lavandulifolia aerial parts were screened for their potential tyrosinase, acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory activity. ET and MS inhibited tyrosinase with IC50 values of 33.4 and 42.8 μg/mL, respectively. The phytochemical in...
متن کاملChemical Constituents of the Essential Oil of Stachys lavandulifolia Vahl from Iran
The essential oil of Stachys lavandulifolia Vahl (Lamiaceae) was isolated by hydrodistillation of the aerial parts of the plant, with a yield of 0.25%. The chemical composition of volatile oil was analyzed by capillary GC and GC/ MS. The main components were germacrene-D (13.2%), ?-phellandrene (12.7%), ?-pinene (10.2%), myrcene (9.4%), ?-pinene (8.4%) and Z-?-ocimene (5.8%).

متن کاملThe chemical constituents of the fungus Stereum sp.
Four new compounds, including a sesquiterpene and three aromatic compounds, and a known compound were isolated from a culture broth of the fungus Stereum sp. The novel sesquiterpene was determined to be stereumone A ((+)-2,3,4a,5,6,7,8a,9-octahydro-5-hydroxy-6,6,9-trimethyl-4,8a-epoxynaphtho[2,3-b]furan-8(8H)-one; 1), and the three new aromatic compounds were elucidated as 3,5-dihydroxy-4-(3-me...
