Published: April 2013

Antimycobacterial effects of thiosemicarbazones were discovered in the late 1940s. The best known representative of these compounds is thioacetazone that has been used in the therapy of tuberculosis since the turn of the 1940s and 1950s. At present, it is used only rarely since it exhibits severe side effects. This paper deals with the antimycobacterial effects of thiosemicarbazones and N,N-dimethylthiosemicarbazones derived from 5-alkyl-2-acetylpyrazines. Some of these compounds displayed high inhibition of the growth of Mycobacterium tuberculosis H37Rv, but were excluded from the in vivo studies due to their cytotoxic effects. Nonetheless, they can be used as model compounds for studying the mechanisms of antimycobacterial action of thiosemicarbazones.

A 70-year-old man developed intermittent fever with chills, severe anorexia, generalized weakness, and mild exertional difficulty in breathing following posterior chamber intraocular lens replacement surgery for a mature white cataract in the left eye. Laboratory tests revealed persistent negative blood cultures, normocytic and normochromic anemia, neutrophilia, and elevated inflammatory markers despite multiple courses of antibiotics. All other investigations conducted to identify the cause of prolonged fever, including transthoracic echocardiography, were negative.

Leptospirosis is a severe and potentially fatal re-emerging zoonotic and waterborne disease caused by pathogenic and intermediate species of Leptospira. Given the high global rates of morbidity and mortality associated with this disease, there is an urgent need to explore alternative therapeutic agents to enhance treatment options. This study investigates the anti-leptospiral efficacy of several common antibiotics-penicillin G, doxycycline, ampicillin, amoxicillin, cefotaxime, chloramphenicol, and erythromycin, as well as extracts from local herbs, Hydnophytum formicarum Jack and Boesenbergia stenophylla, against pathogenic and intermediate Leptospira strains.
