Photosensitizer, with photodynamic effects, makes the skin sensitive to sunlight or artificial ultraviolet light. Its action spectrum is between 320 and 380nm, with the greatest effect at 365nm. Animal tests have shown that methoxsalen has no teratogenic effect. Small-scale human clinical trial data also did not show teratogenic effects.

Synthetic antibacterial anti-tuberculosis drug. It has strong activity against bacteria in the growth and reproduction stage, and has almost no effect on bacteria in the dormant stage. It has high antibacterial activity against various types of mycobacteria. There is no cross-resistance between Mycobacterium tuberculosis and other drugs. It may inhibit the metabolism of sensitive bacteria, inhibit RNA synthesis, and interfere with the protein metabolism of Mycobacterium tuberculosis, thereby causing bacterial death. In large doses, it can cause cleft palate, brain exposure, and spinal deformity in mouse experiments; it can cause mild cervical deformity in rat experiments; it can cause cyclops, short limbs, and cleft palate in rabbit experiments.
