摘要:
Drugs or reagents containing as the active ingredient N-acyloxylated cycloalkyl compounds represented by general formula (I): (wherein A is optionally substituted C4-C5 cycloalkyl which may have one double bond in the ring; and R is C1-C3 alkyl or phenyl). The above compounds are hydroxyamine derivatives functioning as spin trapping agents and can rapidly react with free radicals or active oxygen in an objective organ in spite of their being excellent in stability during the preparation or administration thereof.
摘要:
Disclosed herein is a method for inhibiting the premature polymerization of ethylenically unsaturated monomers comprising adding to said monomers an effective amount of an inhibitor having structural formula (I) wherein R1 and R4 are independently selected from the group consisting of hydrogen, alkyl, and heteroatom-substituted alkyl and R2 and R3 are independently selected from the group consisting of alkyl and heteroatom-substituted alkyl and the portion (II) represents the atoms necessary to form a five-, or six-,seven-membered heterocyclic ring, at least one of said atoms being a carbon atom substituted with a primary, secondary, or tertiary amino group.
摘要:
A treatment process is disclosed that comprises administering an effective amount of an aromatic sulfone hydroxamic acid that exhibits excellent inhibitory activity of one or more matrix metalloprotease (MMP) enzymes, such as MMP-2, MMP-9 and MMP-13, while exhibiting substantially less inhibition at least of MMP-1 to a host having a condition associated with pathological matrix metalloprotease activity. Also disclosed are metalloprotease inhibitor compounds having those selective activities, processes for manufacture of such compounds and pharmaceutical compositions using an inhibitor.
摘要:
This invention relates to a process for the preparation of a compound of formula (I), wherein R1, R2, R3 and R4 are each independently of one another C1-C4alkyl; R5 is H or CH3; and R6 is H or C1-C18alkyl; from a compound of formula II, which comprises dehydrating the compound of formula (II) either a1) in the form of an aqueous solution or suspension, or a2) in the form of an atomised melt together with water vapour at a temperature of above 150 DEG C on a metal oxide or semimetal oxide catalyst. This invention also relates to a process, in which the compounds of formula I are hydrated and then oxidised to the corresponding N-oxyls.
