1-benzyl-3-thioaryl-2-carboxyindoles as potent non-peptide endothelin antagonists
摘要:
Endothelin-1 is a potent vasoconstrictor which is thought to be involved in many human disease states. We have developed a series of indole non-peptide endothelin antagonists which display nanomolar receptor affinity. The representative compound from this series is PD 159433 (22), an ET(A) selective antagonist with an IC50 of 2 nM. The discovery, synthesis and structure-activity relationships of this series of compounds are described. Copyright (C) 1996 Elsevier Science Ltd

; Q; V, G and M have the meanings indicated in the claims. The compounds of formula I are valuable pharmacologically active compounds. They exhibit a strong antithrombotic effect and are suitable, for example, for the therapy and prophylaxis of cardiovascular disorders like thromboembolic diseases or restenoses. They are reversible inhibitors of the blood clotting enzymes factor Xa (FXa) and/or factor VIIa (FVIIa), and can in general be applied in conditions in which an undesired activity of factor Xa and/or factor VIIa is present or for the cure or prevention of which an inhibition of factor Xa and/or factor VIIa is indicated. The invention furthermore relates to processes for the preparation of compounds of formula I, their use, in particular as pharmaceuticals for treating the foregoing conditions, and pharmaceutical preparations comprising them.

substituted right-hand subunit as well as the initial thiomethyl ester reformulation, was confirmed by total synthesis of both (+)- and ent-(-)-1 in studies that also unambiguously established the absoluteconfiguration of the natural product.
The present invention relates to compounds of the formula I,
in which R0 ; R1 ; R2 ; R3 ; R4 ; R5 ; R6 ; R7 ; Q; V, G and M have the meanings indicated in the claims. The compounds of the formula I are valuable pharmacologically active compounds. They exhibit a strong antithrombotic effect and are suitable, for example, for the therapy and prophylaxis of cardiovascular disorders like thromboembolic diseases or restenoses. They are reversible inhibitors of the blood clotting enzymes factor Xa (FXa) and/or factor VIIa (FVIIa), and can in general be applied in conditions in which an undesired activity of factor Xa and/or factor VIIa is present or for the cure or prevention of which an inhibition of factor Xa and/or factor VIIa is intended. The invention furthermore relates to processes for the preparation of compounds of the formula I, their use, in particular as active ingredients in pharmaceuticals, and pharmaceutical preparations comprising them.
The present invention is directed to the compound of formula I which is useful for inhibiting the activity of Factor Xa. The present invention is also directed to compositions containing said compounds, processes for their preparation, their use, such as for inhibiting the formation of thrombin or for therapeutically or prophylactically treating a patient suffering from, or subject to, or associated with a disease state associated with a cardiovascular disorder.

where the formula variables are as defined in the disclosure, advantageously inhibit or block the biological activity of the picornaviral 3C protease. These compounds, as well as pharmaceutical compositions containing these compounds, are useful for treating patients or hosts infected with one or more picornaviruses, such as RVP. Intermediates and synthetic methods for preparing such compounds are also described.
