Smoothened (Smo) is the signal transducer of the Hedgehog (Hh) pathway and its stimulation is considered a potential powerful tool in regenerative medicine to treat severe tissue injuries. Starting from GSA-10, a recently reported Hh activator acting on Smo, we have designed and synthesized a new class of quinolone-based compounds. Modification and decoration of three different portions of the original scaffold led to compounds able to induce differentiation of multipotent mesenchymal cells into osteoblasts. The submicromolar activity of several of these new quinolones (0.4?0.9 muM) is comparable to or better than that of SAG and purmorphamine, two reference Smo agonists. Structure-activity relationships allow identification of several molecular determinants important for the activity of these compounds.

The synthesis and biological activity of two series of nonclassical thymidylate synthase (TS) inhibitors are described. The first is a series of 10-propargyl-5.8-dideazafolic acid derivatives (10a-j) and the second is a series of the analogous 2-desamino derivatives (13a-c,k), both bearing a more lipophilic substituent on the phenyl ring than the CO-glutamate of classical antifolates. Compounds 10a-j were prepared in a straightforward manner, generally by treatment of N-[6-(bromomethyl)-3,4-dihydro-4-oxo-2-quinazolinyl]-2,2- dimethylpropanamide (6) with various phenyl-substituted N-propargylanilines (8), followed by deprotection. Compounds 13a-c,k were prepared similarly from [6-(bromomethyl)-4-oxo-3(4H)-quinazolinyl]methyl 2,2-dimethylpropanoate (11). The compounds were tested for inhibition of purified L1210 TS and for inhibition of L1210 cell growth in vitro. Several of these nonclassical analogues approached the TS inhibitory potency of 10-propargyl-5,8-dideazafolic acid (1, CB3717), a glutamate-containing TS inhibitor. 2-Amino target compounds 10a-j were generally potent inhibitors of L1210 TS, with IC50s within the range of 0.51-11.5 muM, compared to 0.05 muM for 1. The order of potency for phenyl substitution at the 4-position in this series was the following: COCF3?NO2?CONH2?COCH3>SO2NMe2>SO2NMe2>CN>>OCF3?F. The 2-desamino target compounds 13a-c,k also exhibited significant, although diminished, TS inhibition. Both series were growth inhibitory to cells in tissue culture and this inhibition could be reversed by thymidine alone, indicating that the primary targt was TS. None of the compounds was a potent inhibitor of dihydrofolate reductase. These studies indicate that the presence of the glutamate moiety in folate analogues is not an absolute requirement for potent inhibition of TS.

Synthesis and evaluation of quinazolines as inhibitors of the bacterial cell division protein FtsZ

The bacterial cell division protein FtsZ is one of many potential targets for the development of novel antibiotics. Recently, zantrin Z3 was shown to be a cross-species inhibitor of FtsZ; however, its specific interactions with the protein are still unknown. Herein we report the synthesis of analogues that contain a more tractable core structure and an analogue with single-digit micromolar inhibition of FtsZs GTPase activity, which represents the most potent inhibitor of Escherichia coli FtsZ reported to date. In addition, the zantrin Z3 core has been converted to two potential photo-cross-linking reagents for proteomic studies that could shed light on the molecular interactions between FtsZ and molecules related to zantrin Z3.
