The instant invention provides disubstituted tetrazoles that antagonizes the effect of leukotrienes C.sub.4, D.sub.4 or E.sub.4 or any combination thereof in selected tissues. The disubstituted tetrazoles are used in pharmaceutical formulations and methods of treatment of conditions caused by excessive release or production of leukotrienes C.sub.4, D.sub.4 or E.sub.4 or any combination thereof. Such conditions include an immediate hypersensitivity reaction of the type represented by asthma, or by shock or other adverse cardiovascular effects.

The JumonjiC‐domain‐containing histonedemethylase 2A (JMJD2A, KDM4A) is a key player in the epigenetic regulation of gene expression. Previous publications have shown that both elevated and lowered enzyme levels are associated with certain types of cancer, and therefore the definite role of KDM4A in oncogenesis remains elusive. To identify a novel molecular starting point with favorable physicochemical
含有JumonjiC域的组蛋白去甲基化酶2A(JMJD2A,KDM4A)是基因表达的表观遗传调控中的关键角色。以前的出版物表明,升高和降低的酶水平均与某些类型的癌症有关,因此,KDM4A在肿瘤发生中的明确作用仍然难以捉摸。为了鉴定具有良好理化性质的新型分子起点来研究KDM4A的生理作用,我们通过使用两次独立的试验筛选了许多带有铁螯合部分的分子。通过这种方法,我们能够鉴定出2-(1 H-四唑-5-基)乙酰肼为新颖的类似片段的铅结构,相对分子质量低(M r = 142 Da),复杂度低,并且IC 5046.6μ值米在甲醛脱氢酶(FDH) -偶联测定法和2.4μ米在基于抗体的测定法。尽管它的体积很小,但是对于该化合物而言,可以证明它对另外两种脱甲基酶的相对选择性。这是四唑基团作为JMJD脱甲基酶中的战斗部的第一个例子。
