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.

Dinaciclib (SCH 727965) is a selective CDK inhibitor targeting CDK1, CDK2, CDK5, and CDK9 (IC50 = 3/1/1/4 nM). It exhibits potential antitumor activity by inhibiting the incorporation of thoracic glycan (dThd) DNA.

Abemaciclib methanesulfonate (LY2835219) is a specific and effective inhibitor of CDK4(IC50=2 nM) and CDK6(IC50=10 nM).

Palbociclib (PD 0332991) is a CDK inhibitor that inhibits CDK4 and CDK6 (IC50=11/16 nM) and is orally active. Palbociclib has anti-tumorigenic activity and has investigational potential for use in ER-positive and HER2-negative breast cancer.

Palbociclib monohydrochloride (PD 0332991 hydrochloride) is a selective inhibitor of CDK4/6 (IC50s: 11/16 nM). It exhibits no inhibition against a panel of 36 additional protein kinases.

GW 441756 is a specific Tropomyosin-related kinase A (TrkA) inhibitor with an IC50 value of 2 nM.

RO-3306 is a selectivity ATP-competitive CDK1 inhibitor (Ki: 20 nM). The selectivity of RO-3306 for CDK1 is >15-fold higher than a diverse panel of human kinases.

Rafoxanide as a dual CDK4/6 inhibitor for the treatment of skin cancer. Rafoxanide is a salicylanilide used as an anthelmintic. It is used to treat fluke, hookworm and other infestations.
