General Description

5-Ethylthiophenylboronic Acid, also known as the CAS number 161262-33-1, is a chemical compound often used in scientific research, particularly in organic synthesis and pharmaceutical research settings. This chemical belongs to the organoboronic acids group and is characterized by its amorphous off-white appearance. As a boronic acid, it plays a crucial role in the Suzuki reaction, a type of coupling reaction, which allows the formation of carbon-carbon bonds. The exact properties, such as the melting point, boiling point, density, and refractive index of 5-Ethylthiophenylboronic Acid, often depend on its specific form or the conditions it is under. However, like other chemicals, it must be carefully handled and stored to avoid hazards.

Synthesis and characterization of new planar butterfly-shaped fused oligothiophenes

A simple oxidative cyclization reaction was used to construct new seven-ring-fused butterfly-shaped oligothiophene backbone: dibenzothieno[1,2-b: 4,3-b′:6,7-b″:9,8-b″′]tetrathiophene. The new materials show high stability and strong solid state fluorescen

N-aryl thienyl-, furyl-, and pyrrolyl-sulfonamides and derivatives thereof that modulate the activity of endothelin

Thienyl-, furyl- and pyrrolyl-sulfonamides and methods for modulating or altering the activity of the endothelin family of peptides are provided. In particular, N-(isoxazolyl)thienylsulfonamides, N-(isoxazolyl)furylsulfonamides and N-(isoxazolyl)pyrrolylsulfonamides and methods using these sulfonamides for inhibiting the binding of an endothelin peptide to an endothelin receptor by contacting the receptor with the sulfonamide are provided. Methods for treating endothelin-mediated disorders by administering effective amounts of one or more of these sulfonamides or prodrugs thereof that inhibit or increase the activity of endothelin are also provided.
