Isothiazolones
-
, (2008/06/13)
Isothiazolones having the general structure STR1 where A is a monocyclic or bicyclic ring which may contain up to 3 heteroatoms selected from O, S, and N; R1 and R2 are substituent groups such as alkyl, alkoxy, hydroxy, nitro, cyano, amino, and carboxy; and R5 is alkyl, cycloalkyl, phenyl, and Het. The isothiazolones are useful as anti-retroviral agents, anti-inflammatory agents, and anti-atherosclerotic agents.
Chromogenic thiol indicators based on an isobenzothiazolone ring system
-
, (2008/06/13)
Newly synthesized chromogenic thiol-indicating benzoisthiazolone derivatives having the structure: STR1 where R1, R2 and R3 are as defined in the specification, are useful in the detection of thiols, particularly in an aqueous system. This process comprises contacting the aqueous system with a chromogenic thiol-indicating benzoisothiazolone derivative as described herein. Chromophoric changes due to thiol-mediated reduction of the benzothiazolone derivative then occur. Such changes can be in a solution or on an indicator surface in contact or having been in contact with the aqueous system. The chromophoric changes, due to a bathochromic shift in characteristics light absorption upon reduction of the benzoisothiazolone derivative, are proportional to the amount or rate of appearance of thiols in the aqueous system.
