 6-Substituted 2-Oxo-2h-1-Benzopyran-3-Carboxylic Acid Derivatives in a New Approach of the Treatment of Cancer Cell Invasion and MetastasisKempen, I.; Hemmer, Marc  ; Counerotte, Stéphane  et al in European Journal of Medicinal Chemistry (2008), 43(12), 2735-50 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 ... [more ▼] 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. [less ▲] Detailed reference viewed: 85 (23 ULg)
