  Structure–activity relationships of 2-aminothiazoles effective against Mycobacterium tuberculosis

  摘要：

  A series of 2-aminothiazoles was synthesized based on a HTS scaffold from a whole-cell screen against Mycobacterium tuberculosis (Mtb). The SAR shows the central thiazole moiety and the 2-pyridyl moiety at C-4 of the thiazole are intolerant to modification. However, the N-2 position of the aminothiazole exhibits high flexibility and we successfully improved the antitubercular activity of the initial hit by more than 128-fold through introduction of substituted benzoyl groups at this position. N-(3-Chlorobenzoyl)-4-(2-pyridinyl)-1,3-thiazol-2-amine (55) emerged as one of the most promising analogues with a MIC of 0.024 mu M or 0.008 mu g/mL in 7H9 media and therapeutic index of nearly similar to 300. However, 55 is rapidly metabolized by human liver microsomes (t(1/2) = 28 min) with metabolism occurring at the invariant aminothiazole moiety and Mtb develops spontaneous low-level resistance with a frequency of similar to 10 (5).

  N-Heterocyclic dicarboxylic acids: Broad-spectrum inhibitors of metallo-β-lactamases with co-antibacterial effect against antibiotic-resistant bacteria

  摘要：

  In an effort to identify novel, broad-spectrum inhibitors against the metallo-beta-lactamases (M beta Ls), several N-heterocyclic derivatives were tested as inhibitors of M beta Ls CcrA, ImiS, and L1, which are representative enzymes from the distinct M beta L subclasses. Three N-heterocyclic dicarboxylic acid derivatives were competitive inhibitors of CcrA and L1, exhibiting K-i values <= 2 mu M, while only 2,4-thiazolidinedicarboxylic acid (1b) was a competitive inhibitor of ImiS. Two 2-mercapto-1,3,4-thiadiazole derivatives were noncompetitive inhibitors of CcrA and ImiS, exhibiting K-i values <7 mu M; however, these same compounds did not inhibit L1. Two 2-mercapto-1,3,4-triazole derivatives were shown not to inhibit any of the tested M beta Ls. The N-heterocyclic derivatives were tested for antibacterial activity by examining the MIC values for existing antibiotics in the presence/absence of these derivatives. Consistent with the steady-state inhibition data, the inclusion of three N-heterocyclic dicarboxylic acid derivatives resulted in lower MIC values when using Escherichia coli BL21(DE3) cells containing the CcrA or L1 plasmids or Klebsiella pneumoniae (ATCC 700603), while 1b was the only dicarboxylic acid derivative to lower the MIC value of E. coli cells containing the ImiS plasmid. Inclusion of the 2-mercapto-1,3,4-thiadiazole derivatives resulted in lower MIC values for E. coli cells containing ImiS or L1 plasmids; however, these derivatives did not alter the MIC values for K. pneumoniae or E. coli cells containing the L1 plasmid. None of the N-heterocyclic derivatives affected the MIC of two methicillin resistant Staphylococcus aureus (MRSA) strains. Taken together, these studies demonstrate that N-heterocyclic dicarboxylic acids 1a-c and pyridylmercaptothiadiazoles 2a,b are good scaffolds for future broad-spectrum inhibitors of the MbLs.

  Thiosemicarbazones of aromatic aldehydes react with acetic anhydride to give well-defined N4,S-diacetyl derivatives, which readily undergo oxidative cyclisation to 2-aryl-4-acetamido-1,3,4-thiadiazoles. From these intermediates, aryl-thiadiazoles – especially 2-(2′-pyridyl)-1,3,4-thiadiazole, inaccessible by the common methods – can be obtained by acidic deacetylation, SANDMEYER substitution and catalytic

Solvent accessible voids with a volume of 391 Å3 are included in the structure of complex 2, indicating that this complex is a potential host candidate. Thermogravimetric analysis shows that the three complexes are stable up to 100 °C.
