Nafoxidine (U-11,000A) is a non-steroidal antiestrogenic drug that has been investigated to treat advanced breast cancer.^[1] It is structurally related to tamoxifen.

The drug is one of a series of similar structures invented at Upjohn. An earlier compound known as U-11,555 is related to Nafoxidine was found to cause photosensitivity in human volunteers.^[2]^[3]
