Mycobacterium tuberculosis thymidylate kinase (MtTMPK) has emerged as an attractive target for rational drug design. We recently investigated new families of non-nucleoside MtTMPK inhibitors in an effort to diversify MtTMPK inhibitor chemical space. We here report a new series of MtTMPK inhibitors by combining the Topliss scheme with rational drug design approaches, fueled by two co-crystal structures of MtTMPK in complex with developed inhibitors. These efforts furnished the most potent MtTMPK inhibitors in our assay, with two analogues displaying low micromolar MIC values against H37Rv Mtb. Prepared inhibitors address new sub-sites in the MtTMPK nucleotide binding pocket, thereby offering new insights into its druggability. We studied the role of efflux pumps as well as the impact of cell wall permeabilizers for selected compounds to potentially provide an explanation for the lack of correlation between potent enzyme inhibition and whole-cell activity.

experimental part, p. 131 - 136 (2011/07/30)
The present paper describes the synthesis of a series of 8-(cyclopentyloxy)phenyl-xanthines and their evaluation for affinity for A 1 and A2 adenosine receptors using radioligand binding assays. The effects of moving the cyclopentyloxy substituent with or without an ortho methoxy group on the various positions of the 8-phenyl ring have been studied. The vanilloid based xanthines 8-[4-(cyclopentyloxy)-3-methoxyphenyl]-1, 3-dimethylxanthine (6a) (Ki = 100 nM) and 8-[(4-cyclopentyloxy)-3- methoxyphenyl]-3-methyl-1-propylxanthine (12) (Ki = 150 nM) displayed the highest affinity at A2A receptors as well as over 1000 fold selectivity over the A1 adenosine receptor subtype.
