In the 1950s, scientists began systematically examining natural organisms as a source of useful anti-cancer substances. [1] It has been argued that "the use of natural products has been the single most successful strategy in the discovery of novel medicines".
Another demonstration of this reaction type is an alternative route to tamoxifen starting from diphenylacetylene and ethyllithium: [9] The capturing electrophile here is triisopropyl borate forming the boronic acid R–B(OH) 2. The second step completing tamoxifen is a Suzuki reaction. Tamoxifen carbometalation
Toremifene appears to be safer than tamoxifen. [15] It has a lower risk of venous thromboembolism (VTE) (e.g., pulmonary embolism), stroke, and cataracts. [15] The lower risk of VTE may be related to the fact tamoxifen decreases levels of the antithrombin III to a significantly greater extent than either 60 or 200 mg/day toremifene. [15]

On TikTok, there are videos where women talk directly to the camera. They promote the "natural remedies" they say cleared their infections and discuss "holistic healing" recommendations.
Sivifene (A-007) was initially thought to be a SERM due to its structural similarity to tamoxifen but it was subsequently found not to bind to the estrogen receptor (ER). [8] Tesmilifene (DPPE; YMB-1002, BMS-217380-01) is also structurally related to tamoxifen but similarly does not bind to the ER and is not a SERM. [9] [10]
Tamoxifen, sold under the brand name Nolvadex among others, is a selective estrogen receptor modulator used to prevent breast cancer in women and men. [15] It is also being studied for other types of cancer. [15] It has been used for Albright syndrome. [16] Tamoxifen is typically taken daily by mouth for five years for breast cancer. [16]
