Some of the reported derivatives possessed powerful activities greater than in the used controls, such as anti-HIV (e.g., 71 and 74), immunosuppressive (e.g., 17), anti-tumor (e.g., 120, 125, 129, and 131), and antibacterial behavior (e.g., 24, 31, 69, 83, and 85), in addition to tyrosinase (e.g., 1–3), α-glucosidase (e.g., 29, 34, 46, and 47), pancreatic lipase (e.g., 29 and 34), PTP (e.g., 101, 120, and 127), and ACE (e.g., 104) inhibitory behavior. The gene discussed is PNLIP; the disease is neoplasm.
