Phar­ macologically, such compounds are often referred to as "de­ pressors" . The pharmacological action of such drugs is dia­ metrically opposite to "pressors" which are substances that produce a rise in blood pressure. With reference to blood pressure the term depressor is a general one since it is not restrictive in meaning to the manner in which the lowering of blood pressure is brought about# There are, however, other terms used in conjunction with lowering of blood press­ ure which are quite specific in their meaning# For example, antihypertensive is one of such terms. An antihypertensive agent is a substance which lowers the blood pressure to nor­ mal levels by dilating the arteriolar system in hypertensive subjects (1). This is done with no effect upon the function of the heart, or the volume or viscosity of the blood. The ideal drug would affect the blood pressure in normal states to little or no extent# It has only been since about the early 1900 * s that hy­ pertension, a state of abnormal high blood pressure,has been recognized as a disease and treated as such (2). Today hy­ pertension is said to afflict approximately half of the people over fifty years of age (5)# For obvious reasons the 2 need for a depressor agent with antihypertensive properties exists even though there has been some question of the value of the medicinal treatment of the disease (4). Such a drug would not necessarily be one which would lower blood pressure and maintain it at a low level for there are such substances * A drug is needed which would meet the criteria of a true antihypertensive agent but which would have none of the dis­ advantages of the medicinals that are employed for such pur­ pose at the present time. A great number of substances have been used in the past for the treatment of hypertension. For the most part, how­ ever, such drugs can be divided into three groups : bromides and barbiturates, nitrites and nitrates, and thiocyanates (5). These drugs have certain disadvantages. The seda­ tives, bromides and barbiturates, must be administered in relatively large doses in order to obtain the proper results. This is very undesirable. The nitrites and nitrates are either too brief in their duration of action, the absorption is too variable, or side-effects such as headache, weakness and depression are produced. The thiocyanates are toxic as evident by weakness, muscular aching, nausea and vomiting, dizziness and confusion. A review of the literature reveals that information on the relationship of depressor activity and chemical struct­ ure is nil. Depressor activity has been observed with va­ rious chemical substances during their pharmacological in­ vestigation; however, it seems that many such compounds
