The present invention relates to processes for removal of Michael acceptors from certain compositions wherein the composition is treated with a thiol-containing compound under conditions sufficient to remove Michael acceptors and the resulting thiol-Michael adducts. Certain embodiments of the present invention enable quantification and/or removal of Michael acceptors and/or Michael acceptor precursors.

Process for reducing contaminating Michael acceptor levels in oxycodone and other compositions

Compounds having an isoindolin-1-one backbone of Formula (I) are disclosed which have utility in treating and/or preventing microbial infections, tumor growth, metastasis and other macrophage migration inhibitory factor (MIF)-modulated pathological conditions. Pharmaceutical compositions and methods and use of compounds of Formula (I) are also disclosed. 

Isoindolin-1-ones as macrophage migration inhibitory factor (MIF) inhibitors

Process for reducing contaminating michael acceptor levels in oxycodone and other compositions

The present invention provides synthetic &#x3b2;-secretase peptide substrates useful in various assays for measuring &#x3b2;-secretase activity. Antibodies that recognize the synthetic substrates and uses of the antibodies in various assays are disclosed. The herein disclosed peptide substrates are hydrolyzed at rates substantially faster than the attendant Swedish mutant APP from which the substrate sequences are derived.

Beta-secretase substrates and uses thereof

The abuse potential of a bioavailable drug such as an opiate analgesic agent is reduced and its duration of action is extended by converting it to a poorly absorbed ester prodrug or other prodrug derivative prior to formulation. Unlike many existing sustained release formulations of active pharmaceutical agents wherein an active pharmaceutical agent can be released by chewing, crushing, or otherwise breaking tablets or capsule beads containing the active pharmaceutical agent, such mechanical processing of tablets or capsule beads containing a prodrug of this invention neither releases the active drug nor compromises the controlled conversion of prodrug to drug. Moreover, tablets and capsule beads containing prodrugs of this invention or other drugs can be formulated with a sufficient amount of a thickening agent such as hydroxypropylmethylcellulose or carboxymethylcellulose to impede inappropriate intravenous and nasal administration of formulations that are not indicated for these modes of administration.

Compounds and methods for lowering the abuse potential and extending the duration of action of a drug

The present invention is directed to compounds and pharmaceutical compositions comprising the compounds which are inhibitors of the enzyme gamma secretase and which are useful in the treatment or prevention of diseases in which the beta-amyloid peptide is involved, such as Alzheimer's disease.

Investigational compounds

The invention is a method for treating an inflammatory disease in a patient which comprises treating the patient with an oral composition comprising a thrombin inhibitor. Such diseases include but are not limited to nephritis, systemic lupus erythematosus, rheumatoid arthritis, glomerulonephritis and sarcoidosis.

Method for treating inflammatory diseases by administering a thrombin inhibitor

A compound which inhibits human thrombin and where has the structure ##STR1## such as ##STR2##

Thrombin inhibitors

A method for introducing a mutation into a desired site in Herpes Simplex Virus Type 1 uses a set of starting vectors, where each starting vector has a fragment of the substantially complete HSV-1 genome and also DNA which overlaps with a sequential genomic fragment contained in other starting vectors, so that upon co-transfection of a host cell, replication of viral DNA, and recombination, a mutated replicable virus is formed. The starting vector containing a gene which is to be mutated is replaced by a replacement vectors. The replacement vectors contain a copy of the mutated gene and overlapping DNA, and genomic DNA which was present in the starting vector. A host cell is transformed with the replacement vectors and the remaining starting vectors under conditions allowing replication of viral DNA and recombination to form a replicating mutated virus. In preferred embodiments, the protease gene is mutated.

Method of making herpes simplex type 1 mutants and mutants so produced

4-substituted cyclohexylamine derivatives which are thrombin catalytic site inhibitors and which are useful as anticoagulants. These compounds show selectivity for thrombin over other trypsin-like enzymes and have oral bioavailability. They have the formula ##STR1## for example ##STR2##

The invention is directed to a series of novel compounds, and their pharmaceutically acceptable salts, of the formula ##STR1## wherein R is C.sub.0-6 alkyl substituted with R.sup.5 or a mono or polycyclic aromatic or heteroaromatic system comprised of 5 or 6-membered aromatic or heteroaromatic rings that are either unsubstituted or substituted with one or more of R.sup.1 and R.sup.2 ; R.sup.1 and R.sup.2 are independently C.sub.1-6 alkyl, carboxyl, hydroxyl, azido, nitro, amino, C.sub.1-6 alkylamino, C.sub.1-6 dialkylamino, arylamino, aryl C.sub.1-6 alkylamino, hydroxysulfonyl or arylazo; aryl is a phenyl or naphthyl ring which is unsubstituted or substituted with one or more of R.sup.3 and R.sup.4 ; R.sup.3 and R.sup.4 are independently C.sub.1-6 alkyl, azido, nitro, amino, C.sub.1-6 dialkylamino or hydroxysulfonyl; R.sup.5 is ##STR2## provided that when R is an unsubstituted monocyclic ring, the monocyclic ring is not phenyl or pyridyl. Such compounds are useful as fluorescent probes for identifying antiplatelet agents which selectively bind to activated platelets.
