Cholesterol (cholesteryl alcohol) is a natural product that is the major sterol in mammals and an agonist of estrogen-related receptor α (ERRα). Cholesterol is widely found in the cell membranes of animals and is also used in the synthesis of several important hormones and bile acids.

Estradiol benzoate (Benzhormovarine) is the synthetic benzoate ester of estradiol, a steroid sex hormone vital to the maintenance of fertility and secondary sexual characteristics in females.

Chrysin (5,7-Dihydroxyflavone) exhibits many biological activities and pharmacological effects, including antioxidant, anti-inflammatory, anticancer, and antiviral activities.

Estrone (Aquacrine) is an aromatized C18 steroid with a 3-hydroxyl group and a 17-ketone, a major mammalian estrogen. It is converted from ANDROSTENEDIONE directly, or from TESTOSTERONE via ESTRADIOL. In humans, it is produced primarily by the cyclic ovaries, PLACENTA, and the ADIPOSE TISSUE of men and postmenopausal women.

Octinoxate (Octyl 4-methoxycinnamate) is used is in sunscreens and other cosmetics to absorb UV-B rays from the sun, protecting the skin from damage,primarily as an ingredient in some sunscreens and lip balms. It is also used to reduce the appearance of scars.

Vepdegestrant (ARV-471) is an estrogen receptor (ER) α PROTAC molecule that degrades ER in ER-positive breast cancer cell lines with a DC50 of approximately 1 nM. It can reduce the expression of classically regulated ER target genes and inhibit the growth of ER-dependent cell lines (including those expressing ESR1 variants, such as Y537S and D538G) by degrading ER.

(+)-JQ-1 (JQ1) is a specific, reversible BET bromine domain inhibitor that targets BRD4 (1/2) with IC50 values of 77/33 nM. (+)-JQ-1 induces cell autophagy and inhibits cell proliferation.

Ibrutinib (PCI-32765) is an irreversible inhibitor of BTK (IC50: 0.5 nM) that selectively blocks B cell activation.
