Abstract:
The present invention relates generally to pharmaceutical agents, and in particular, to metalloprotease inhibitor compounds. More particularly, the present invention provides a new class of dual acting MMP-2 and MMP-9 inhibiting compounds that exhibit increased potency, metabolic stability and/or reduced toxicity in relation to currently known MMP-2 and MMP-9 inhibitors for the treatment of pain and other diseases. Additionally, the present invention relates to methods for treating pain, addiction and/or withdrawal symptoms in a patient comprising administering to the patient a pain-reducing effective amount of a present compound.
Abstract:
The present disclosure generally relates to an improved process for alkylating a triiodo-substituted arylamide to form a compound suitable for use as an X-ray contrast agent. More particularly, the present disclosure is directed to such a process that limits the formation of fused bicyclic impurities, such as Impurity G, in the alkylation reaction mixture.
Abstract:
The invention relates to novel cyclic hydrocarbon compounds and derivatives thereof, processes for the preparation thereof, to said compounds for use as a medicament, to said compounds for use in therapy, to pharmaceutical compositions comprising said compounds, to methods of treating diseases with said compounds, and to the use of said compounds in the manufacture of medicaments.
Abstract:
Disclosed is a novel benzyloxypropylamine derivative having an excellent tachykinin receptor antagonistic effect. This compound shows a good transfer into the blood and a long blood half-life in the blood kinetic test using a guinea pig orally administered with the compound and is stable in an animal plasma. The compound also shows a high transfer to the central nervous system when it is orally administered to a guinea pig at a certain dose. Accordingly, the benzyloxypropylamine derivative is quite useful as a novel anti-tachykinin agent.
Abstract:
The present invention relates to the composition, process of preparation, and use of novel derivatives prepared from 1,5-bis-(4'-carbomethoxyphenyl)-1,4-pentadien-3-one. These novel compositions can act as crosslinkers with polyfunctional monomeric, oligomeric, and/or polymeric anhydrides, esters, carboxylic acids, isocyantes, epoxies, carbonates, acetoacetates, and alkoxylated melamines.
Abstract:
An asymmetric synthesis of diarylmethylpiperazines is described. The synthetic route enables preparation of a variety of enatiomerically pure amines with different N-alkyl groups. The invention includes an asymmetric addition of organometallic compounds to chiral sulfinimine to give adducts in predominantly one diastereomer can subsequently be transferred into pure enantiomers of by cleavage of the chiral auxilliary which is followed by synthesis of the piperazine ring by alkylation procedures.
Abstract:
A diaminobenezene derivative represented by the general formula (1), and a polyimide obtained by reacting a diamine containing at least 1 mol% of said diaminobenzene derivative, with a tetracarboxylic acid and its derivative to obtain a polyimide precursor having a reduced viscosity of from 0.05 to 5.0 dl/g (in N-methylpirrolidone at a temperature of 30°C, concentration: 0.5 g/dl) and ring-closing it, and having a repeating unit represented by the general formula (2), as well as a liquid crystal alignment film containing said polyimide. (in the formula (1), P is a single bond or a bivalent organic group selected from -O-, -COO-, and -CONH-, Q is a cyclic substituent selected from an aromatic ring, an aliphatic ring, a hetero ring and their substitution products, R 1 is an aliphatic ring, and R 2 is a C 1-22 straight chain alkyl group, and in the formula (2), A is a tetravalent organic group constituting a tetracarboxylic acid, B is a bivalent organic group constituting a diamine, and P, Q, R 1 and R 2 are the same as in the above formula (1)).
