Synthesis of .alpha.-methylene-.gamma.-butyrolactones: a structure-activity relationship study of their allergenic power
摘要:
Thirty-five alpha-methylene-gamma-butyrolactones have been prepared and their allergenic properties tested on the skin of guinea pigs experimentally sensitized to (a) alantolactone (1), (b) isoalantolactone (2), and (c) alpha-methylene-gamma-butyrolactone (3). The two first groups of animals cross-react to lactones containing 9 to 18 carbon atoms but not to smaller alpha-methylene-gamma-butyrolactones. Conversely, animals sensitized to alpha-methylene-gamma-butyrolactone react only with alpha-methylene-gamma-butyrolactones containing 6 and 7 carbon atoms. These results are discussed in relation with the allergic contact dermatitis mechanism.

This paper describes the synthesis of adamantane aminolactones (AdAL 6 and PhAdAL 16) and their tetrahydrofuran analogues (AdAE 9 and PhAdAE 19). Their convulsant activity was studied in mice. It was found to be weaker than that of the aminolactones or aminotetrahydrofurans, which have a phenyl group in place of the adamantane ring. Studies on the antagonism of the convulsant action of these derivatives, by GABAergic or glycinergic agonists appear to show the simultaneous development of dopaminergic, antiGABAergic (for the AdAE and PhAdAE) and antiglycinergic (for the AdAL and PhAdAL) central activities. These properties could be interesting in the treatment of the late stages of the Parkinson's disease.
