The metabolism of cis- and trans-decalin.
1. The metabolism of cis- and trans-decalin in the rabbit has been investigated. 2. Both hydrocarbons were oxidized to racemic secondary alcohols and excreted as ether glucuronides in amounts equal to about 60% of the dose administered. The principal glucuronides were isolated as triacetyl methyl esters and as sodium salts. 3. cis-Decalin gave rise mainly to (+/-)-cis-cis-2-decalol, together wi...
متن کاملThe metabolism of cis- and trans-indane-1,2-diol.
1. The metabolism of cis-indane-1,2-diol, trans-indane-1,2-diol, indene epoxide and 2-hydroxyindan-1-one in rats has been studied. The substances were administered to the animals by subcutaneous injection. 2. The urine of the dosed animals was examined for the presence of free and conjugated cis- and trans-dihydrodiols, and for each compound it was possible to isolate both cis and trans forms o...
متن کاملIsolation of Pyrrolocins A–C: cis- and trans-Decalin Tetramic Acid Antibiotics from an Endophytic Fungal-Derived Pathway
Three new decalin-type tetramic acid analogues, pyrrolocins A (1), B (2), and C (3), were defined as products of a metabolic pathway from a fern endophyte, NRRL 50135, from Papua New Guinea. NRRL 50135 initially produced 1 but ceased its production before chemical or biological evaluation could be completed. Upon transfer of the biosynthetic pathway to a model host, 1-3 were produced. All three...
متن کاملEffect of Alkyl Substituents on the Hydrogen Catalytic Osmylation of Cis and Trans 2-Cyclohexene-Cyclohexanol
Catalytic osmylation of cis and trans 2-cyclohexene-cyclohexanol (1a) and (1b) are carried out in the presence of N-methyl morpholine-N-oxide. Under the same conditions, only the cis isomer reacted, leading to triol (3). The steric hindrance of the equatorial OH group probably prevents the trans isomer from entering into such reaction. Triol (3) was also obtained from the reduction of the d...
متن کاملThe Metabolism of 14C-Labeled cis and trans Isomers of Octadecenoic and Octadecadienoic Acids
The physical properties of common unsaturated fatty acids are altered when they are converted to their geometric isomers. For example, isomerization of the naturally occurring cis acid, oleic acid, to its trans form, elaidic acid, raises its melting point by 30”, changing it from a liquid to a solid at body temperature. Theoretically, such isomeric pairs might be expect.ed to differ in their me...
