  Small Molecule Inhibitors of Dynamin I GTPase Activity:  Development of Dimeric Tyrphostins

  摘要：

  Dynamin I is a GTPase enzyme required for endocytosis and is an excellent target for the design of potential endocytosis inhibitors. Screening of a library of tyrphostins, in our laboratory, against the GTPase activity of dynamin I gave rise to a mu M potent lead, 2-cyano-3-(3,4-dihydroxyphenyl)thioacrylamide (1, IC50 70 mu M). Our initial investigations suggested that only the dimeric form of 1 displayed dynamin I GTPase inhibitory activity. Subsequent synthetic iterations were based on dimeric analogues and afforded a number of small molecules, low mu M potent, inhibitors of dynamin I GTPase, in particular, symmetrical analogues with a minimum of two free phenolic -OHs: catechol-acrylamide (9) (IC50 = 5.1 +/- 0.6 mu M), its 3,4,5-trihydroxy congener (10) (IC50 = 1.7 +/- 0.2 mu M), and the corresponding 3-methyl ether (11) (IC50 = 9 3 mu M). Increasing the length of the central alkyl spacer from ethyl to propyl (22-24) afforded essentially identical activity with IC50'S of 1.7 0.2, 1.7 0.2, and 5 +/- 1 mu M, respectively. No decrease in activity was noted until the introduction of a hexyl spacer. Our studies highlight the requirement for two free amido NHs with neither the mono-N-methyl (86) nor the bis-N-methyl (87) analogues inhibiting dynamin I GTPase. A similar effect was noted for the removal of the nitrile moieties. However, modest potency was observed with the corresponding ester analogues of 9-11: ethyl ester (90), propyl ester (91), and butyl ester (92), with IC50'S of 42 3, 38 2, and 61 2 mu M, respectively. Our studies reveal the most potent and promising dynamin I GTPase inhibitor in this series as (22), which is also known as BisT.

  New analogues of 2-[2-substituted-3-(3,4-dichlorobenzylamino)propylamino]quinolin-4-ones, 26a, 26b, 31a-e, 34, 35, 38 and 40, have been synthesized and evaluated against Staphylococcus aureus methionyl-tRNA synthetase. All of the synthesized compounds were less active than the reference compound 2. The compounds were also screened against various strains of S. aureus and Enterococci for their antibacterial activities. Among the compounds, 26b, 31c and 31e displayed significant inhibitory properties against various strains of Enterococci compared to compound 2. (C) 2008 Elsevier Masson SAS. All rights reserved.
