  3,6-Disubstituted Coumarins as Mechanism-Based Inhibitors of Thrombin and Factor Xa

  摘要：

  In this work, coumarins were screened on thrombin (THR) and factor Xa (FXa), two of the most promising targets for the development of anticoagulant drugs. This allowed us to highlight compound 30, characterized by a 2,5-dichlorophenyl ester in the 3-position and a chloromethyl moiety in the 6-position, as a very potent THR inhibitor (k(i)/K-I, = 37 000 M-1 s(-1)). Moreover, this compound exhibits good selectivity over FXa (168-fold) and trypsin (54-fold). The mechanism of inactivation was investigated in this series and significantly differs from that previously observed with (x-chymotrypsin. Indeed, the addition of hydrazine on the THR-inhibitor complex promotes a partial induced THR reactivation. This reactivation, confirmed by LC/MS, showed the resurgence of the native THR and a new dihydrazide complex. Docking experiments were then efficiently used to explain the trends observed in the enzymatic assays as well as to corroborate the postulated inhibition mechanism. Finally, the cell permeability of our derivatives was estimated using a computational approach.

  inhibitory potency toward alpha-CT and HLE. Cycloalkyl esters and amides were found to be essentially inactive on both enzymes. On the opposite, aromatic esters strongly inactivated alpha-CT whereas HLE was less efficiently inhibited with dichlorophenyl ester derivatives (kinact/K(I) = 4000 M(-1) s(-1) for 36). Representative examples of amide, ester, thioester and ketone derivatives were prepared in order

  Novel 6-substituted 2-oxo-2H-1-benzopyran-3-carboxylic acid derivatives were synthesized and their potency in reducing the invasive behaviour of HT 1080 fibrosarcoma cells was evaluated. Structure-activity relationships were deduced from biological results and will be used in further design of new active compounds. In particular, the acetoxymethyl substituent found at the 6-position of previously described active compounds can be replaced by an acetamidomethyl substituent without loss of potency; while the presence of an aryl ester function at the 3-position was preferred to a thioester or an amide function to induce marked biological activity. This work confirms the interest of aryl esters of 6-substituted coumarin-3-carboxylic acids as potential new anti-cancer agents. (C) 2008 Elsevier Masson SAS. All rights reserved.
