  Synthesis and Structure−activity Relationships of Antitubercular 2-Nitroimidazooxazines Bearing Heterocyclic Side Chains

  摘要：

  Recently described biphenyl analogues Of the antituberculosis drug PA-824 displayed improved potencies against M. tuberculosis but were poorly soluble. Heterobiaryl analogues of these, in which the first phenyl ring was replaced with various 5-membered ring heterocycles, were prepared with the aim of identifying potent new candidates with improved aqueous solubility. The compounds were constructed by coupling the chiral 2-nitroimidazooxazine alcohol with various halomethyl-substituted arylheterocycles, by cycloadditions to a propargyl ether derivative of this alcohol, or by Suzuki couplings on haloheterocyclic methyl ether derivatives. The arylheterocyclic compounds were all more hydrophilic than their corresponding biphenyl analogues, and several showed solubility improvements. 1-Methylpyrazole, 1,3-linked-pyrazole, 2,4-linked-triazole, and tetrazole analogues had 3- to 7-fold higher MIC potencies against replicating M. tb than predicted by their lipophilicities. Two pyrazole analogues were >10-fold more efficacious than the parent drug in a mouse model of acute M. tb infection, and one displayed a 2-fold higher solubility.

  optimization on phenyl ring at the R2 site on the pyrazole displayed promising antimycobacterial activity paired with low cytotoxicity. In particular, compound 10d displayed good activity (MIC = 5.69 μg/mL) with low inhibition of CYP 2C9 (IC50 > 10 μM), consequently low potential risk of drug-drug interaction. These promising results provide new insight into the combination regimen using sulfonamide

  本研究通过系统优化抗菌药物磺胺苯唑，设计合成了一系列磺胺类化合物，用于治疗结核分枝杆菌（M.tuberculosis，M.tuberculosis）。初步结果表明，4-氨基苯磺酰胺部分在维持抗分枝杆菌活性方面起着关键作用。化合物10c、10d、10f和10i通过优化吡唑上R 2位点的苯环显示出良好的抗分枝杆菌活性和低细胞毒性。特别是，化合物10d显示出良好的活性（MIC = 5.69 μg/mL），对 CYP 2C9 的抑制（IC50  > 10 μM），因此药物相互作用的潜在风险较低。这些有希望的结果为使用磺胺作为治疗结核分枝杆菌的一种成分的联合方案提供了新的见解。
