This paper reports the synthesis of a series of 5H-1,2,4-triazino[5,6-b]indole 3 and 4, and aminoindole 12-23, derivatives, obtained from isatin 1 and from oxoindole 5, respectively. All the new compounds were studied as antihypertensive agents in spontaneously hypertensive rats (SHR), and as inhibitors of platelet aggregation in guinea pig whole blood, induced by arachidonic acid (AA), adenosin-5'-diphosphate (ADP) or collagen. The most active antiaggregating compounds were also studied as thromboxane A2 synthetase inhibitors.
