Abstract:
The present invention relates to a novel squaramide derivative and a use thereof and provides a novel derivative through the strategy of replacing a compound having a urea core with the bioisolate squaramide, whereby the derivative exhibits an anticancer activity through eIF2α phosphorylation efficacy, wherein squaramide has a characteristic structure retaining a double bond linked to the carbonyl groups and the squaramide structure can be prepared by mediating a precursor bearing an amine group to the squarate ring, which is a squaric ring, through a conjugate addition reaction.
Abstract:
α- and β-amino acid hydroxyethylamino sulfonamide compounds are effective as retroviral protease inhibitors, and in particular as inhibitors of HIV protease.
Abstract:
The present invention relates to a method of producing a highly pure crystal, which includes crystallization of a benzenesulfonamide derivative of the following formula (1) using a polar solvent as a good solvent (e.g., alcohol or a mixed solvent of alcohol and water) and water as a poor solvent, and a novel crystal of a nitrobenzenesulfonamide derivative of the following formula (2), which is an intermediate for the derivative, and a production method thereof:

Abstract:
Diamine compounds of formula (I) or an addition salt thereof are provided: ##STR1## These compounds have an excellent cerebral protective action, are very safe, and exhibit a strong action when orally administered, and therefore, medicines containing such compounds are effective for treating disorders caused by cerebral hemorrhage, cerebral infarction, subarachnoid hemorrhage, transient ischemic attack, cerebrovascular disorders and the like, or preventing progress of such disorders.
Abstract:
Methods for treating retroviral infection or inhibiting HIV integrase in target cells or in a patient involve administering to target cells or to a patient in need of treatment an effective amount of at least one having a disulfonamide scaffold which is represented by the formula: wherein, independent of each other, each X independently represents hydrocarbyl, halogeno, amino, substituted amino, or alkoxy, wherein substituted amino is represented by —NR3,R4 wherein R3 and R4, are not both hydrogen and independently represent alkyl or alkenyl, n is an integer of 0, 1, 2, or 3, each Y independently represents hydrocarbyl, halogeno, amino, substituted amino or alkoxy, wherein substituted amino is represented by —NR3,R4 wherein R3 and R4, are not both hydrogen and independently represent alkyl or alkenyl, m is an integer of 0, 1, 2, or 3, and R represents di-valent hydrocarbyl, substituted or unsubstituted.
Abstract:
An improved process is described to resolve a racemic mixture in any proportion of 5-(2-(2-(2-ethoxyphenoxy)ethylamino)propyl)-2-methoxy benzene sulfonamide as a free base or some of its salts, with BPA either S or R form to obtain enantiomerically highly pure R and S-isomer as a well characterized free base or as a salt of the title compound. Also described are novel R and S-isomers of 5-(2-(2-(2-ethoxyphenoxy) ethylamino)propyl)-2-methoxy benzene sulfonamide and their salts and the processes for their preparation.
Abstract:
This invention provides a novel class of sulfonamide compounds of formula I which are aspartyl protease inhibitors: ##STR1## This invention also provides pharmaceutical compositions comprising these compounds. The compounds and pharmaceutical compositions of this invention are particularly well suited for inhibiting HIV-1 and HIV-2 protease activity and consequently, may be advantageously used as anti-viral agents against the HIV-1 and HIV-2 viruses. This invention also provides methods for inhibition aspartyl protease activity and methods for treating viral infections using the compounds and compositions of this invention.
