The defensive secretion of the julid diplopod Typhloiulus orpheus contains methyl N-methylanthranilate (MNMA), an ester of N-methylanthranilic acid that comprises more than 99% of secretion of this species. MNMA is accompanied by small amounts of methyl anthranilate and two benzoquinones (2-methyl-1,4-benzoquinone and 2-ethyl-1,4-benzoquinone, respectively). MNMA is a known intermediate in the biosynthesis of both benzoquinones (as present in defensive secretions of juliformians) and glomerin-like quinazolines (chemical defense in Glomerida). The compound may have evolved independently in the pathway to glomeridan chemistry, or may even represent a pivotal branching point in the pathway to different chemical classes of diplopod defensive chemistry.

N-甲基邻氨基苯甲酸甲酯：香蒲（Typhloiulus orpheus）（Diplopoda，Julida）的防御性分泌物中的主要化合物。

菊科双足类节肢动物的防御性分泌物含有N-甲基邻氨基苯甲酸甲酯（MNMA），N-甲基邻氨基苯甲酸的酯，占该物种分泌的99％以上。MNMA伴有少量邻氨基苯甲酸甲酯和两个苯醌（分别为2-甲基-1,4-苯醌和2-乙基-1,4-苯醌）。MNMA是苯醌（存在于水母的防御性分泌物中）和肾小球蛋白样喹唑啉（Glomerida中的化学防御作用）的生物合成中的已知中间体。该化合物可能在肾小球化学的途径中独立发展，甚至可能代表了双足类防御化学的不同化学类别的关键分支点。
