Novel compounds of the following formula: ##STR1## WHEREIN R' is alkyl of 1 to 3 carbon atoms, X.sup.- is a nontoxic anion; b and c are positive numbers having values such that the positive charge of b moles of cation are neutralized by c moles of anion X.sup.-; and -N is a bicyclic heterocyclic base, of the group consisting of: ##STR2## wherein the dotted line indicates that the methyl group can be present or a hydrogen group can be present, with the proviso that the two alpha methyl groups are not present at the same time, but that one alpha methyl group is required. These compounds have superior coccidiostatic activity.
以下是该文献的中文翻译:
以下是具有以下结构的新化合物:##STR1##
其中,R'是1至3个碳原子的烷基,X.sup.-是一种无毒的阴离子;b和c是正数,其值使b摩尔的阳离子的正电荷被c摩尔的阴离子X.sup.-中和;-N是一个双环杂环碱基,属于以下组:##STR2##
其中,虚线表示甲基基团可以存在或氢基团可以存在,但两个α-甲基基团不能同时存在,但必须存在一个α-甲基基团。这些化合物具有优异的抗球虫活性。
