Excerpt from American Journal of Pharmacy, Vol. 73: June, 1901 Observations prove that it is not the hydroxyl groups in them selves nor always the terminal groups that determine solely the action of a substance, but the character and complexity of the mole cule. However, these groups assist in bringing the entire molecule into action with certain chemical compounds in the organism. When the reactive group which exerts the selective action of the compound in the organism is slightly altered or covered, then under conditions we can prevent the action of the entire compound. Between such terminal groups as hydroxyl or methoxyl and certain nerve centers or points in the organism where chemical substances react, definite chemical relations must exist. Through changes in these terminal groups we are able to move the point of attack of the substance or to render it absolutely inactive, but as long as it remains active, the fundamental characters of its action (although frequently modified) always manifest themselves, as for example the alkaloids and their derivatives.
