Abstract
Betulinic acid (triterpene) has shown an immense potential towards the development of anticancer, antiviral, antimalarial, antifungal, antioxidant and antiprotozoal agents. Cis-platin (cytotoxic agent) has diverted attention of chemists towards organotin complexes with marked pharmacological activities. In present work aniline derivatives of Betulinic acid were synthesized followed by the synthesis of diorganotin and triorganotin metal complexes. These complexes were characterized by FT-IR and multinuclear NMR (1H and 13C) spectroscopy. The ligands and their organotin(IV) complexes were screened for antibacterial, antifungal and antioxidant activities. Compound L22SnMe2 was found with maximum antibacterial activity among the screened compounds. Compounds L12SnMe2 and L12SnPh2 were found with remarkable antifungal activity. Similarly L1, L12SnBu2, L2 and L22SnMe3 were remarked with good antioxidant activity.
