  3-[1-(2-Benzoxazolyl)hydrazino]propanenitrile derivatives: inhibitors of immune complex induced inflammation

  摘要：

  3-[1-(2-Benzoxazolyl)hydrazino]propanenitrile derivatives were evaluated in the dermal and pleural reverse passive Arthus reactions in the rat. In the pleural test these compounds were effective in reducing exudate volume and accumulation of white blood cells. This pattern of activity was similar to that of hydrocortisone and different from that of indomethacin. The structural requirements for inhibiting the Arthus reactions were studied by systematic chemical modification of 1. These structure-activity relationship studies revealed that nitrogen 1' of the hydrazino group is essential for activity and must be electron rich, whereas chemical modifications of other sites of 1 had only a modest effect on activity.

  The synthesis of a wide variety of 9-substituted-3-oxo-3H-2,9-dihydropyridazino[3,4,5-de]phthalazines (11) was achieved by treatment of 3-substituted-3,4-dihydro-4-oxophthalazine-5-carboxylic esters (10) with hydrazine hydrate. These esters were prepared from 3-hydroxyphthalide-7-carboxylic acid (7) by two different routes. Under basic conditions, alkylation of 3-oxo-3H-2,9-dihydropyridazino[3,4,5-de]phthalazine (1) gave 9-substituted products. These undergo further alkylation at the 2-position. Some of them were converted to 3-chloro, 3-thiono, and 3-hydrazino compounds by standard methods. Dehalogenation of selected 3-chloro compounds or desulphurization of 3-thiono derivatives gave 1-substituted-1H-pyridazino[3,4,5-de]phthalazines (22), some of which were also prepared by direct alkylation of the parent heterocycle 2 under basic conditions. However, treatment of 2 or its 1-methyl homologue with methyl iodide resulted in products in which nitrogen attached to carbon had been attacked rather than the 1- or 9-position. Treatment of the acid chloride of 3,4-dihydro-4-oxophthalazine-5-carboxylic acid with methyl hydrazine led to 2-methyl-3-oxo-3H-2,9-dihydropyridazino[3,4,5-de]phfhalazine (21a) which was purified by cyanoethylation at the 9-position, recrystallization, and hydrazinolysis of the cyanoethyl group. Biological testing revealed that many of the compounds lowered blood pressure in animal models but none had a sufficient therapeutic ratio of activity vs. side effects to warrant clinical trial.

  一种广泛的9-取代-3-氧代-3H-2,9-二氢吡啶并[3,4,5-de]邻苯二氮酮（11）的合成是通过将3-取代-3,4-二氢-4-氧代邻苯二酮-5-羧酸酯（10）与水合肼处理而实现的。这些酯是通过两种不同的途径从3-羟基邻苯二酮-7-羧酸（7）制备的。在碱性条件下，3-氧代-3H-2,9-二氢吡啶并[3,4,5-de]邻苯二酮（1）的烷基化产生了9-取代产物。这些产物在2-位进一步发生烷基化。其中一些经过标准方法转化为3-氯、3-硫代和3-肼基化合物。选择性去卤化3-氯化合物或去硫化3-硫代衍生物得到1-取代-1H-吡啶并[3,4,5-de]邻苯二氮酮（22），其中一些也是通过在碱性条件下直接烷基化母环2制备的。然而，用碘甲烷处理2或其1-甲基同分异构体的结果是氮连接到碳而不是1-位或9-位。用甲基肼处理3,4-二氢-4-氧代邻苯二酮-5-羧酸酰氯导致2-甲基-3-氧代-3H-2,9-二氢吡啶并[3,4,5-de]邻苯二氮酮（21a），通过在9-位进行氰基乙基化、再结晶和氰基乙基基团的肼解纯化。生物测试显示许多化合物在动物模型中降低了血压，但没有一个具有足够的活性与副作用之间的治疗比例，值得进行临床试验。
