Abstract: This invention discloses uses for nicardipine in preparing anti-lung cancer products. This invention provides uses for nicardipine in the preparation of products to treat non-small cell lung cancer. From carrying out cancer drug repositioning for the FDA- and CFDA-approved drug nicardipine, experiments for this invention show, based on screening of non-anti-cancer drugs for various cancer cell lines (tissue types) and mutation sites, that nicardipine has a new use as an anti-small cell lung cancer and/or anti-non small cell lung cancer medication, thus achieving a new purpose for an old drug.

Abstract: This invention discloses uses for etonogestrel in preparing anti-prostate cancer products. This invention provides uses for etonogestrel in preparing anti-prostate cancer products. From carrying out cancer drug repositioning for the FDA- and CFDA-approved drug etonogestrel, experiments for this invention show, based on screening of non-anti-cancer drugs for various cancer cell lines (tissue types) and mutation sites, that etonogestrel has a new use as an anti-prostate cancer medication, thus achieving a new purpose for an old drug.

Abstract: This invention discloses uses for levonorgestrel in preparing anti-ovarian cancer products. This invention provides uses for levonorgestrel in the preparation of products to treat ovarian cancer. From carrying out cancer drug repositioning for the FDA- and CFDA-approved drug levonorgestrel, experiments for this invention show, based on screening of non-anti-cancer drugs for various cancer cell lines (tissue types) and mutation sites, that levonorgestrel has a new use as an anti-ovarian cancer medication, thus achieving a new purpose for an old drug.

Abstract: This invention discloses uses for estradiol in preparing anti-small cell lung cancer and/or ovarian cancer and/or osteosarcoma products. This invention provides uses for estradiol in preparing anti-small cell lung cancer and/or ovarian cancer and/or osteosarcoma products. From carrying out cancer drug repositioning for the FDA- and CFDA-approved drug estradiol, experiments for this invention show, based on screening of non-anti-cancer drugs for various cancer cell lines (tissue types) and mutation sites, that estradiol has a new use as an anti-small cell lung cancer and/or ovarian cancer and/or osteosarcoma medication, thus achieving a new purpose for an old drug.

Abstract: This invention discloses applications of desogestrel in the preparation of anti-colon cancer/breast cancer ER-negative Ah receptor-positive products. This invention provides applications for desogestrel in the preparation of products to treat colon cancer and/or breast cancer. From carrying out cancer drug repositioning for the FDA- and CFDA-approved drug desogestrel, experiments for this invention show, based on screening of non-anti-cancer drugs for various cancer cell lines (tissue types) and mutation sites, that desogestrel has a new use as an anti-colon cancer medication, thus achieving a new purpose for an old drug.

Abstract: This invention discloses uses for sulindac in preparing anti-lung cancer products. This invention provides uses for sulindac in the preparation of products to treat lung cancer. From carrying out cancer drug repositioning for the FDA- and CFDA-approved drug sulindac, experiments for this invention show, based on screening of non-anti-cancer drugs for various cancer cell lines (tissue types) and mutation sites, that sulindac has a new use as an anti-lung cancer medication, thus achieving a new purpose for an old drug.
