    • The invention provides for the use of antimicrobial chemical entities based on a nitrothiazolide backbone that exhibit anti-mycobacteria activity, including the mycobacterium causing tuberculosis. Multiple compounds were synthesized and screened for anti-tuberculosis activity. Disclosed herein are a series of compounds with anti-tuberculosis activity, including six leads that completely inhibited bacterial growth at 5 micrograms per ml or less. Three of these compounds were tested to determine MIC and these ranged between 1 and 4 micrograms per ml against both drug susceptible Mycobacterium tuberculosis strains and strains that are multi-drug resistant (MDR) including XDR strains. The compounds developed are derived from parent compound nitazoxanide, which had no inhibitory activity in the stringent testing format used herein. The derivatives were synthesized using a di-nitro-thiophene or 4-Chloro-5-Nitro-thiazole scaffold and R groups connected via a peptide bond (NHCO) to cyclic compounds such as benzene, thiophene or furans. Many of these compounds have broad spectrum activity against Gram positive bacteria including Staphylococcus aureus (MRSA) and Staphylococcus epidermidis. Several of these lead compounds were not toxic for mice at 200 mg/Kg doses administered over a period of three days.
    • 本发明提供了基于显示抗分枝杆菌活性的硝基噻唑内酯骨架的抗微生物化学实体的用途,所述抗微生物化学实体包括引起结核病的分枝杆菌。 合成多种化合物并筛选抗结核活性。 本文公开了一系列具有抗结核活性的化合物,包括六种导致完全抑制5微克/ ml或更少的细菌生长的导致。 对这些化合物中的三种进行测试以确定MIC,并且这些化合物针对药物敏感的结核分枝杆菌菌株和包括XDR菌株在内的多药耐药性(MDR)菌株,均在1和4微克/ ml之间。 所开发的化合物衍生自母体化合物硝唑尼特,其在本文使用的严格测试形式中没有抑制活性。 使用二硝基 - 噻吩或4-氯-5-硝基 - 噻唑骨架和R基团通过肽键(NHCO)连接环状化合物如苯,噻吩或呋喃来合成衍生物。 许多这些化合物对革兰氏阳性菌包括金黄色葡萄球菌(MRSA)和表皮葡萄球菌具有广谱活性。 这些先导化合物中的几种在三天内以200mg / Kg剂量施用对小鼠无毒。
