We report the initial results of our study into a series of simple 4′-O-sulfamoyl-4-biphenyl based compounds as novel inhibitors of the enzyme estrone sulfatase (ES). The results of the study show that these compounds are potent inhibitors, possessing greater inhibitory activity than COUMATE, but weaker inhibitory activity than EMATE or the tricyclic derivative of COUMATE, namely 667-COUMATE. Furthermore, the compounds are observed to be irreversible inhibitors.

Herein we report a room temperature Fe-catalyzed coupling reaction of various bromophenols with aryl Grignard reagents, which exhibits a wide substrate scope and high functional group tolerance. For the first time, the combination of simple Fe(acac)3/PBu3/Ti(OEt)4 has been used as an effective catalyst for the biaryl couplings of bromophenols or their Na or K salts with debromination and etherification side reactions being well suppressed. Various biphenols including natural product garcibiphenyl C as well as pharmaceutical diflunisal and its ethyl ester were facilely synthesized using the present protocol. (Figure presented.).

Paragraph 0086; 0088, (2017/07/14)
PROBLEM TO BE SOLVED: To provide a novel azo dichroic dye having solubility for practical use while maintaining high contrast order parameter (S value). SOLUTION: There is provided azo dichroic dye represented by the formula (I), where Ar1 to A1 are each independently a substituted/unsubstituted 1,4-phenylene group, a substituted/unsubstituted naphthylene group or a substituted/unsubstituted (E)-cyclohexane-1,4-diyl group, X1 is a direct bond or a bivalent group, L1 is a direct bond or a bivalent group containing no cyclic structure nor azo bond, B1 and B2 are direct bond or bivalent group containing no cyclic structure nor azo bond and Y1 and Y2 are specific general formulae.
