LONG-ACTING CONTRACEPTIVE AGENTS: TESTOSTERONE ESTERS OF CYCLOALKYLCARBOXYLIC ACIDS
The synthesis of twenty five esters of testosterone (17β -hydroxyandrost- 4-en-3-one) is described. All esters are derivatives of cycloalkycarboxylic acids. Some of the esters possess α- , β -and/or & - substitution in the ester side-chain. The work was undertaken in order to evaluate long-acting male antifertility effect of such esters. Most of the compounds, especially compound No.1, wer...
متن کاملEffects of aliphatic fatty acids
octanoate or decanoate per mol of albumin caused a decrease in dye binding (dye/protein molar ratio 1 : 1), which, in contrast with additional fatty acid, was very pronounced: 1-8mol of palmitate or stearate resulted in a small, and apparently linear, displacement of Phenol Red. The displacement effect of 1-5 mol of oleate, linoleate or linolenate per mol of albumin was comparable with that of ...
متن کاملSynthesis of Pyrrole Phosphonate Esters: Emphasis on Pyrrole NH Acids and Dialkylacetylenic Esters Substitution
Reaction of dialkyl acetylenedicarboxylates 1a-c andpyrrole derivatives 2a-e in the presence of triphenylphosphite (TPP) was investigated and the effect of the pyrrole substitution was established. Diastereoselectivity is observed with pyrroles, 2a,b, yieldingphosphonate ester derivatives 3a-f and 4,and their relative configuration is determined by 1H/13C and 31</...
متن کاملThe hydrolysis of phosphate esters of alpha-hydroxy acids catalyzed by molybdate.
Frequent observations have been made of the increased rate of hydrolysis of relatively labile phosphate compounds in acid molybdate solution (e.g. phosphocreatine (I), acetyl phosphate (2), and 1,3-diphosphoglyceric acid (3)). A study by Weil-Malherbc and Green (4) indicated that ATP, pyrophosphate, phosphoenolpyruvate, and fructosr B-phosphate were hydrolyzed appreciably in the pH range 3 to 5...
