Abstract: 6-heterocyclic-4-amino-1,3,4,5-tetrahydrobenz[cd]indoles are provided which are useful in modifying the function of serotonin in mammals.

Abstract: The invention discloses modified forms of the enzyme tissue plasminogen activator (t-PA) in which recombinant DNA techniques are utilized to modify the structure of the t-PA cDNA to express a modified t-PA which retains the ability to activate plasminogen yet binds less efficiently to plasmin inhibitor. The invention provides novel DNA compounds and recombinant DNA expression vectors that encode modified human t-PA wherein all or a portion of the kringle protein domains of native human t-PA are removed. Both eukaryotic and prokaryotic expression vectors containing the modified t-PA DNA have been constructed and used to transform Chinese hamster ovary cells and Escherichia coli cells.
