target for the development of anti-Brucella agents. In this work, we cloned and overexpressed the HDH-encoding gene from Brucella suis, purified the protein and evidenced its biological activity. We then investigated the inhibitory effects of a series of substituted benzylic ketones derived from histidine. Most of the compounds reported here inhibited B. suis HDH in the lower nanomolar range and constitute
布鲁氏菌属。是布鲁氏菌病(马耳他热)的病原体,布鲁氏菌病是世界上最广泛的人畜共患病。该病原体能够在人类中建立持续的感染,即使使用抗生素治疗也难以根除。此外,布鲁切拉被认为是一种潜在的生物恐怖主义行为。组蛋白醇脱氢酶(HDH,EC 1.1.1.23)已被证明对于这种病原体的宏吞噬复制是必不可少的。因此,它构成了抗Brucella药剂开发的原始且新颖的靶标。在这项工作中,我们从猪布鲁氏菌中克隆并过表达了HDH编码基因,纯化了该蛋白质并证明了其生物学活性。然后,我们研究了一系列从组氨酸衍生的取代苄基酮的抑制作用。
