Abstract: Compounds of formula (I) that are capable of acting as purine receptor antagonists, pharmaceutical compositions including the compounds, and methods of making the compounds, are disclosed. The compounds and compositions can be used in treating or preventing disorders related to purine receptor hyperfunctioning.

Abstract: Compounds of formula (I); wherein R1 is H or NHZ; R2 is optionally substituted aryl or heteroaryl attached via a carbon atom; R3 is H; optionally substituted C1-C6alkyl, C2-C6alkenyl, C2-C6alkynyl, or C3 C7 cycloalkyl, halogen; OH or OR, or R4 is H, optionally substituted C1-C6alkyl, C3 C6alkenyl, C3-C6alkynyl, C3-C7 cycloalkyl, aryl or heteroaryl, R5 is H or optionally substituted C1-C6alkyl, C3-C6alkenyl, C3-C6alkynyl, or C3-C7 cycloalkyl; or R4 and R5 together form a 5 or 6-membered heterocyclic ring; and R10 is optionally substituted C1-C6alkyl; are purine receptor, particularly adenosine receptor antagonists, useful for treatment of, inter alia, movement disorders such as Parkinsons disease.

Abstract: The present invention relates to a series of substituted bis aryl and heteroaryl compounds of formula (I): Wherein X, Y, Z, A, B, D, Ar, R1 and R2 are as defined herein. The compounds of this invention are selective 5HT2A antagonists, and are therefore, useful in treating a variety of diseases including but not limited to a wide variety of sleep disorders as disclosed and claimed herein.

Abstract: Compounds of formula (I) are antibacterial agents: wherein Z represents a radical of formula —N(OH)CH(═O) or of formula —C(═O)NH(OH), and R1-R4 are as defined in the specification. A method for the treatment of bacterial or protozoal infections in humans and non-human mammals, which comprises administering to a subject suffering such infection an antibacterially or antiprotozoally effective dose of a compound of formula (I) or a pharmaceutically or veterinarily acceptable salt, hydrate or solvate thereof.

Abstract: A compound of formula (I) wherein X is —COOH or —CONHOH Y is a group of formula (ID) or (IE) or a pharmaceutically acceptable salt, hydrate, or solvate thereof. The compounds are inhibitors of matrix metalloproteinases involved in tissue degradation.

Abstract: The present invention relates to therapeutically active hydroxamic acid, N-formyl-N-hydroxyamino and carboxylic acid derivatives, their preparation, and pharmaceutical compositions containing them. These compounds are useful in the inhibition of metalloproteases, such as stromelysin, gelatinase, matrilysin, and collagenase. These compounds are useful in the treatment of mammals having disease-states alleviated by the inhibition of such matrix metalloproteases.

Abstract: A compound of formula (I) useful as metalloproteinase inhibitors.

Abstract: Compounds of formula (I) ##STR1## wherein n, V, R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are as defined in the specification are matrix metalloproteinase inhibitors.

Abstract: A process for the preparation of a compound of formula (I) wherein R.sub.2 is a (C.sub.1 -C.sub.6)alkyl, (C.sub.2 -C.sub.6)alkenyl, (C.sub.2 -C.sub.6)alkynyl, phenyl(C.sub.1 -C.sub.6)alkyl, heteroaryl(C.sub.1 -C.sub.6)alkyl, cycloalkyl(C.sub.1 -C.sub.6)alkyl or cycloalkenyl(C.sub.1 -C.sub.6)alkyl group, any one of which may be optionally substituted by one or more substituents selected from (C.sub.1 -C.sub.6)alkyl, (C.sub.1 -C.sub.6)alkyl, --S(C.sub.1 -C.sub.6)alkyl, halo and cyano (--CN); and R.sub.7 is a carboxylic acid protecting group, which process comprises the internal molecular rearrangement of an allyl carboxylate compound of formula (II) wherein R.sub.2 and R.sub.7 are as defined in relation to formula (I) to form the desired compound of formula (I). Compounds (I) are intermediates for the preparation of Matrix metaloproteinase inhibitors.
