A process for the manufacture of sulfamoyl anthranilic acids of the general formula I ##STR1## in which Ph is phenyl substituted with 1 or 2 halogen atoms, alkyl groups or etherified hydroxy groups, and R is aralkyl, heteroaralkyl or cycloalkyl-alkyl, unsaturated in the aliphatic moiety, including oxygen or sulfur and/or substituted with halogen, alkyl or alkoxy in the aromatic moiety, by reacting carboxylic acids with at least one mol-equivalent of an amine (R--NH.sub.2) at a temperature above 120.degree. C.
Rational design of compounds that would bind specific pockets of the target proteins is a difficult task in drugdesign. The 12 isoforms of catalytically active humancarbonicanhydrases (CAs) have highly similar active sites that make it difficult to designinhibitorsselective for one or several CA isoforms. A series of CA inhibitors based on 2-chloro/bromo-benzenesulfonamide that is largely fixed

Coloring matters represented by general formula (1) or salts thereof are simply provided at a low cost as water-soluble coloring matters which exhibit absorption in the near-infrared region. Further, aqueous ink compositions which contain the coloring matters and have excellent storage stability are also provided. In general formula (1), Nc is optionally substituted naphthalocyanine; M is a metal oxide or the like; R
