Lipids of human and equine smegma

Lipids of human and equine smegma. O'Neill, H. J.; Gershbein, L. L. (Biochem. Res. Lab., Northwest Inst. Med. Res., Chicago, Ill.There are some reagents with their cas registry numbers 5711-28-4 and 7683-64-9 are used in this study., USA). Oncology, 33(4), 161-6 (English) 1976. CODEN: ONCOBS. DOCUMENT TYPE: Journal CA Section: 13 (Mammalian Biochemistry) The lipids of human and equine smegma pools were saponified and the total fatty acids submitted to temp.-programmed gas chromatog. anal. In contrast to the human products, the horse smegma fatty acids contained very low odd satd. as well as olefinic branched chain acid contents. The cyclopropane fatty acid, 9,10-methyleneoctadecanoic acid, occurred in smegma sampled from men over 35 years of age but could not be detected in the pool from persons of 17-20 years of age nor in any of the equine mixts. The alc. fraction from horse smegma contained .apprx.85% sterol, the remainder constituting alcs. of C12 to C28 and of which 43.5% were branched chain components. The corresponding product from human smegma was primarily sterol. Squalene comprised the main hydrocarbon present in smegma of either species. .

Effect of triparanol and 3

Effect of triparanol and 3.beta.-(.beta.-dimethyl-aminoethoxy)-androst-5-en-17-one on growth and nonsaponifiable lipids of Saccharomyces cerevisiae. Fung, Bess; Holmlund, Chester E. (Dep. Chem., Univ. Maryland, Coll. Park, Md., USA). Biochem. Pharmacol.In this article, certain chemicals are used. Some of their cas registry numbers are 57-87-4 and 7683-64-9 , 25(11), 1249-54 (English) 1976. CODEN: BCPCA6. DOCUMENT TYPE: Journal CA Section: 1 (Pharmacodynamics) Section cross-reference(s): 10 Triparanol [78-41-1] (8 .times. 10-5M) completely suppressed growth of S. cerevisiae and (even at 2 .times. 10-5M) sharply inhibited NaOAc-1-14C incorporation into nonsaponifiable lipids, probably by interference with the conversion of lanosterol [79-63-0] to ergosterol [57-87-4] and, to a lesser extent, by inhibition of squalene [7683-64-9] oxidn. 3.beta.-(.beta.-Dimethylaminoethoxy)-androst-5-en-17-one (I) [7635-03-2] (10-4M) showed only slight inhibition of growth, but at 10-6M significantly altered the pattern of nonsaponifiable lipids, causing the accumulation of an unidentified 14C-labeled compd. At 10-4M I 2,3-oxidosqualene was the major nonsaponifiable compd. accumulated, which on prolonged incubation was converted to one or more compds. less polar than lanosterol. .
