Squaric Acids: A New Motif for Designing Inhibitors of Protein Tyrosine Phosphatases

(Equation presented) Protein tyrosine phosphatases (PTPases) are important targets in medicinal chemistry. These enzymes play a role in a number of human diseases, including type II diabetes and infection by Yersinia pestis, the causative agent of bubonic

Squaraine Chemistry. Synthesis, Characterization, and Optical Properties of a Class of Novel Unsymmetrical Squaraines: (4'-methoxyphenyl)squaraine and Its Derivatives

A class of novel, unsymmetrical squaraines, namely (4'-methoxyphenyl)squaraine and its derivatives USq-1-13, which were designed to improve the spectral response of photoconductive squaraines in xerographic devices in the visible

Photoconductive imaging members with unsymmetrical squaraine compositions

Unsymmetrical squaraine compounds such as substituted dialkylaminophenylalkoxyaryl squaraines, and imaging members comprised of the aforementioned squaraines.

Unsymmetrical squaraine compositions and photoconductive imaging members using such compositions

Unsymmetrical squaraine compounds of the formula wherein R1, R2 and R3 are independently selected from alkyl groups or aryl groups; X is hydrogen, hydroxy, alkyl, alkoxy, or halogen; n is a number of 1 to about 3; and m is a number of from 0 to about 2. The compounds can be prepared by a cycloaddition-condensation reaction. Photoconductive imaging members including such compounds are also described.

Oxocarbons and Related Compounds; Part 15. Meerwein-Arylation of Semisquaric Acid and Semisquaric Amides. A General Method for the Preparation of 3-Aryl-4-hydroxy- and 3-Amino-4-aryl-3-cyclobutene-1,2-diones.

Meerwein-arylation of semisquaric acid (1) and semisquaric amides 4 has been found to afford general routes to 3-aryl-4-hydroxy-3-cyclobutene-1,2-diones 3 and 3-amino-4-aryl-3-cyclobutene-1,2-diones 5 respectively.
