The invention discloses applications of a novel phosphodiesterase 4 (PDE4) inhibitor ZL-n-91 in preparation of medicines preventing lung cancer proliferation and metastasis. A survivorship curve and in-vitro cell experiments of mice prove that the phosphodiesterase 4 inhibitor ZL-n-91 can significantly inhibit lung cancer cell proliferation and metastasis, indicating that the phosphodiesterase 4 inhibitor ZL-n-91 is expected to be an important target in lung cancer proliferation and metastasis preventing researches, and providing bases for preparing medicines preventing lung cancer proliferation and metastasis. The phosphodiesterase 4 inhibitor ZL-n-91 has a good application prospect.

The present invention relates to a phosphodiesterase 4 inhibitor capable of avoiding vomiting. The phosphodiesterase 4 inhibitor is a compound, a prodrug or a solvate represented by DTPM; and the DTPM is named as 1-(4-difluoro methoxy-3-(tetrahydrofuran-3-oxyl) phenyl)-3-dimethyl-1-ketone, and has a chemical formula shown as below. A plurality of experiments have proved that the DTPM has better effect on improvement of learning and memory compared with an existing antidepressant PDE4 inhibitor; in a Beagle dog vomiting effect observation experiment, no obvious vomiting inducing reaction is observed; and the DTPM has an inhibitor intensity 5000 times of that of other PDE4D families. The inhibitor provided by the invention can become a drug for treating depression and Alzheimer's disease and improving the cognitive ability, and capable of effectively reducing and even avoiding adverse reactions like vomiting.
