Abstract: 4-Azahexacyclo (5.4.1.0.sup.2,6 .0.sup.3,10 .0.sup.5,9 .0.sup.8,11) dodecane compounds of the formula ##STR1## wherein R, A and B each is hydrogen; a linear or branched alkyl group having one to twelve carbon atoms and optionally including a hydroxyl or halogen substituent; or a phenyl group alone or optionally substituted with a linear or branched alkyl group having one to twelve carbons, which group optionally includes a hydroxyl or halogen substituent; and X is a hydroxyl or --NR.sub.2 group where R is as stated above; or an acid addition salt of such compound. These compounds are useful in pharmaceutical compositions wherein the compound is included in an amount effective to be used as a calcium antogonist, a cardiac agent or an anti-hypertensive agent.

Abstract: The invention provides oleanolic acid and/or a physiologically acceptable salt thereof for use in treating a patient prophylactically and/or therapeutically for ulcerogenic-type disorders of the stomach and/or intestines. The ulcerogenic disorders can be of the type chemically induced and/or stress-induced.The invention also provides a pharmaceutical composition comprising an active amount of oleanolic acid and/or a physiologically acceptable salt thereof in combination with an analgesic compound and/or an anti-inflammatory compound. The invention further provides for use of oleanolic acid in preventing and/or significantly reducing and/or therapeutically treating ulcerogenic-type disorders of the stomach and/or intestines.

Abstract: Pentacyclo[6.3.0.0..sup.2,6.0.sup.3,10.0.sup.5,9 ]undecane and its derivatives are prepared. The compounds find use as antiviral agents.
