Cyclocondensation reaction of 4-(2-bromoacetyl)quinolin-1-ium bromide (4a–d) with substituted arylthiourea, (5a–g) afforded 4-(6-substituted quinolin-4-yl)-N-aryl/pyridyl thiazol-2-amine (6a-ab). These newly synthesized derivatives were evaluated for in vitro antibacterial activity against Escherichia coli (NCIM 2574), Proteus mirabilis (NCIM 2388) (Gram-negative strains), Bacillus subtilis (NCIM 2063), Staphylococcus albus (NCIM 2178) (Gram-positive strains) and in vitro antifungal activity against Aspergillus niger (ATCC 504) and Candida albicans (NCIM 3100). Compounds 6a, 6b, 6d, 6f, 6k, and 6l showed moderate to good antibacterial activity against S. albus. Ten derivatives 6c, 6q, 6r, 6s, 6t, 6v, 6w, 6x, 6y, and 6aa, showed moderate to good activity against A. niger. N-[4-(Quinolin-4-yl)-1,3-thiazol-2-yl]pyridin-2-amine presented comparable activity against A. niger with respect to standard drug Rouconazole.

Fibroblast activation protein (FAP) is a serine protease that is generally accepted to play an important role in tumor growth and other diseases involving tissue remodeling. Currently there are no FAP inhibitors with reported selectivity toward both the closely related dipeptidyl peptidases (DPPs) and prolyl oligopeptidase (PREP). We present the discovery of a new class of FAP inhibitors with a N-(4-quinolinoyl)-Gly-(2-cyanopyrrolidine) scaffold. We have explored the effects of substituting the quinoline ring and varying the position of its sp2 hybridized nitrogen atom. The most promising inhibitors combined low nanomolar FAP inhibition and high selectivity indices (>10 3) with respect to both the DPPs and PREP. Preliminary experiments on a representative inhibitor demonstrate that plasma stability, kinetic solubility, and log D of this class of compounds can be expected to be satisfactory.

Page/Page column 53, (2013/07/31)
The present invention relates to novel inhibitors having high selectivity and specificity for FAP (fibroblast activation protein). Said inhibitors are useful as a human and/or veterinary medicine, in particular for the treatment and/or prevention of FAP-related disorders such as but not limited to proliferative disorders.
