ABSTRACT

Schiff’s base constitutes a significant class of compounds for new drug development. They are widely used for industrial purposes and also exhibit a broad range of biological activities. The search for Schiff’s base containing compounds with more selective activity and lower side effects continues to be an active area of argument examination in medicinal chemistry. The biphenyl molecule consists of two connected phenyl rings. Biphenyl ring scaffolds are fairly non-reactive in nature. They enhance the log-P values; increase the tropical polar surface area (TPSA) of the molecule, act as hydrophobic carrier across biological membrane, thus, increasing the bioavailability of compounds. In the present work, a series of Schiff’s bases of biphenyl-4-carboxylic acid have been synthesized. These derivatives were characterized by elemental analysis, IR, and 1H NMR spectral data and have been explored for anti-bacterial, anti-fungal and anti-tubercular activities. The synthesized compounds have shown excellent anti-fungal potential, making them good candidates for future studies in antifungal research.
