  Synthesis and Structure−Activity Studies of Biphenyl Analogues of the Tuberculosis Drug (6S)-2-Nitro-6-{[4-(trifluoromethoxy)benzyl]oxy}-6,7-dihydro-5H-imidazo[2,1-b][1,3]oxazine (PA-824)

  摘要：

  A series of biphenyl analogues of the new tuberculosis drug PA-824 was prepared, primarily by coupling the known (6S)-2-nitro-6,7-dihydro-5H-imidazo[2,1-b][1,3]oxazin-6-ol with iodobenzyl halides, followed by Suzuki Coupling Of these iodides with appropriate arylboronic acids or by assembly of the complete biaryl side chain prior to coupling with the above alcohol. Antitubercular activity was determined under both replicating (MABA) and nonreplicating (LORA) conditions. para-Linked biaryls were the most active, followed by meta-linked and then ortho-linked analogues. A more detailed study of a larger group of para-linked analogues showed a significant correlation between potency (MABA) and both lipophilicity (CLOGP) and the electron-withdrawing properties of terminal ring substituents (Sigma sigma). Selected compounds Were evaluated for their efficacy in a mouse model of acute Mycobacterium tuberculosis infection. In vivo activity correlated well with the stability of compounds to microsomal metabolism. Three compounds bearing combinations of lipophilic, electron-withdrawing groups achieved >200-fold higher efficacies than the parent drug.

  New heterocyclic analogues of the potent biphenyl class derived from antitubercular drug PA-824 were prepared, aiming to improve aqueous solubility but maintain high metabolic stability and efficacy. The strategy involved replacement of one or both phenyl groups by pyridine, pyridazine, pyrazine, or pyrimidine, in order to reduce lipophilicity. For para-linked biaryls, hydrophilicities (ClogP) correlated with measured solubilities, but highly soluble bipyridine analogues displayed weak antitubercular activities. A terminal pyridine or proximal heterocycle allowed retention of potency and provided solubility improvements, particularly at low pH, with examples from the latter classes displaying the better in vivo efficacies, high metabolic stabilities, and excellent pharmacokinetics. Five such compounds were >100-fold better than the parent drug in a mouse model of acute Mycobacterium tuberculosis infection, and two orally bioavailable pyridine analogues (3-4-fold more soluble than the parent at low pH) were superior to antitubercular drug OPC-67683 in a chronic infection model.

  Novel extended side chain nitroimidazooxazine analogues featuring diverse linker groups between two aryl rings were studied as a potential strategy to improve solubility and oral activity against chronic infection by Mycobacterium tuberculosis. Both lipophilic and highly polar functionalities (e.g., carboxamide, alkylamine, piperazine, piperidine, but not sulfonamide) were well tolerated in vitro, and the hydrophilic linkers provided some solubility improvements, particularly in combination with pyridine rings. Most of the 18 compounds further assessed showed high microsomal stabilities, although in the acute infection mouse model, just one stilbene (6-fold) and two pyridine-containing acetylene derivatives (5-fold and >933-fold) gave in vivo efficacies notably superior to the clinical stage compound pretomanid (PA-824). The most efficacious analogue also displayed outstanding in vivo activity in the stringent chronic model (up to 24-fold better than the drug delamanid and 4-fold greater than our previous best phenylpyridine candidate), with favorable pharmacokinetics, including good oral bioavailability in the rat.
