Lisinopril is a potent, competitive inhibitor of angiotensin-converting enzyme (ACE). Lisinopril is marketed under the brand name ZESTRIL. ZESTRIL is indicated for the treatment of hypertension. It may be used alone as initial therapy or concomitantly with other classes of antihypertensive agents. It is also indicated as adjunctive therapy in the management of heart failure in patients who are not responding adequately to diuretics and digitalis. Lisinopril inhibits angiotensin-converting enzyme (ACE) in human subjects and animals. ACE is a peptidyl dipeptidase that catalyzes the conversion of angiotensin I to the vasoconstrictor substance, angiotensin II. Angiotensin II also stimulates aldosterone secretion by the adrenal cortex. The beneficial effects of lisinopril in hypertension and heart failure appear to result primarily from suppression of the renin-angiotensin-aldosterone system. Inhibition of ACE results in decreased plasma angiotensin II which leads to decreased vasopressor activity and to decreased aldosterone secretion. While the mechanism through which ZESTRIL lowers blood pressure is believed to be primarily suppression of the renin-angiotensin-aldosterone system, ZESTRIL is antihypertensive even in patients with low-renin hypertension.

Vapiprost is a potent dicyclopentadiene thromboxane receptor antagonist that was being developed by Glaxo Wellcome in Japan. Vapiprost has been shown to be a potent and specific thromboxane (Tx)A2 receptor blocking drug in vitro using platelets and both vascular and airways smooth muscle preparations from different species. The drug is active in various experimental models of thrombosis. The potential clinical applications for a thromboxane receptor blocking drug include the treatment of thrombotic events and occlusive vascular disease. Phase III trials were underway in Japan for the treatment of deep vein thrombosis, which later were discontinued.

Suramin is an antiprotozoal and anthelmintic compound. It is indicated for the treatment of African trypanosomiasis (African sleeping sickness; trypanosome fever) and Onchocerciasis (river blindness). Additionally, suramin exhibits antineoplastic action. It was discovered that suramin produced dramatic, but transient, improvement of core symptoms of autism spectrum disorder.
