Caulophylline B is primarily studied for its potential biological activities, particularly in the context of anti-inflammatory and immunomodulatory effects. It has shown inhibitory activity against certain pro-inflammatory cytokines, suggesting possible application in managing inflammatory conditions. Research also indicates moderate cytotoxic effects on specific cancer cell lines, making it a compound of interest in early-stage anticancer studies. Due to its natural origin and structural complexity, it serves as a candidate for pharmacological research and development of novel therapeutic agents. However, its applications remain largely experimental, with studies confined to in vitro and preclinical models.
