Leniquinsin acts as a vasodilator and shows antihypertensive effects. It is a potent rat brain phosphodiesterase inhibitor. Its hypotensive effect would seem to be due to alpha-adrenergic blockade and to a direct action on smooth muscle.

Nifuraldezone is an antibacterial compound. It completely mimics the radiosensitizing effect of molecular oxygen in hypoxic mammalian cells in vitro at concentrations in tissue culture medium which showed no measurable acute toxicity.

Nifurdazil, a 5-nitrofuran derivative, ia an antibacterial agent.

U0126 is a highly selective inhibitor of both MEK1 and MEK2, a type of MAPK/ERK kinase. The inhibitory effects of U0126 on MEK and ERK activation have been confirmed repeatedly, and treatments with U0126 have been shown to inhibit proliferation and migration of cancer cells in vivo and in vitro. U0126 has been widely used as an inhibitor for the Ras/Raf/MEK/ERK signaling pathway. U0126 treatments lead to cancer cell death, which agrees with the well-known role of the Ras/Raf/MEK/ERK pathway in supporting cell survival. U0126 enhances apoptosis in human breast cancer MCF-7 cells, acute myeloid leukemia, and PC12 cells.
