Abstract: Brucella spp. is the causative agent of brucellosis (Malta fever), which is the most widespread zoonosis worldwide. The pathogen is capable of establishing persistent infections in humans which are extremely difficult to eradicate even with antibiotic therapy. Moreover, Brucella is considered as a potential bioterrorism agent. Histidinol dehydrogenase (HDH, EC 1.1.1.23) has been shown to be essential for the intramacrophagic replication of this pathogen. It therefore constitutes an original and novel 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 attractive candidates for the development of novel anti-Brucella agents.
