2,2′-Bithiophene-5,5′-diboronic acid (BTDBA) is a boronic acid derivative of the heterocyclic compound bithiophene. Bithiophene compounds with boronic acid groups are often utilized in the synthesis of conjugated polymers and small organic molecules that have applications in organic electronics, such as organic photovoltaic cells, organic field-effect transistors, and organic light-emitting diodes. The boronic acid functionalities allow for Suzuki-Miyaura cross-coupling reactions, a powerful tool for forming carbon-carbon bonds in organic synthesis. 2,2′-Bithiophene-5,5′-diboronic acid acts via a variety of mechanisms, including inhibition of cell proliferation, induction of apoptosis, and inhibition of angiogenesis. 2,2′-Bithiophene-5,5′-diboronic acid may act to inhibit the growth of bacteria, fungi, viruses, and cancer cells. It also has anti-inflammatory, antioxidant, and anti-angiogenic properties.
