Zusammenfassung:The present invention relates to novel terpene alkaloids and their use as antiparasitic agents. The present invention also relates to an antiparasitic agent which comprises a terpene alkaloid compound of this invention as an effective ingredient in an antiparasitic formulation. More particularly, the present invention relates to derivatives of the terpene alkaloid (1S,2R,4aS,5R,8R,8aR)-2-(acetyloxy)- 8a-hydroxy-3,8-dimethyl-5-(1 -methylethenyl)-1,2,4a,5,6,7,8,8a-octahydronaphthalen-1-yl (2S,3aR,9bR)-6 -chloro-9b-hydroxy-5- methyl-1,2,3,3a,5,9b-hexahydropyrrolo[2,3-c][2,1]benzoxazine-2-carboxylate. Pharmaceutical compositions comprising the same are also disclosed. Ovaj pronalazak se odnosi na nove terpenske alkaloide i njihovu upotrebu kao antiparazitskih agenasa. Ovaj pronalazak se takodje odnosi na antiparazitski agens koji sadrži terpensko alkaloidno jedinjenje iz ovog pronalaska kao efikasni sastojak u antiparazitskoj formulaciji. Odredjenije, ovaj pronalazak se odnosi na derivate terpenskog alkaloida (1S,2R,4aS,5R,8R,8aR)-2-(acetiloksi)-8a-hidroksi3,8-dimetil-5-(1-metiletenil)-1,2,4a,5,6,7,8,8a-oktahidronaftalin-1-il (2S,4aR,9bR)-6-hloro-9b-hidroksi-5-metil-1,2,3,3a,5,9b-heksihidropirolo [2,3-c][2,1]benzoksazin-2-karboksilata. Opisani su takodje farmaceutski preparati koji sadrže iste.
