Calcipotriol (CAS 112965-21-6)

Calcipotriol, a synthetic derivative of vitamin D3 in its hydrate form, plays a pivotal role in the research landscape due to its unique mechanism of action that distinctively influences cell behavior without significantly altering calcium homeostasis. This compound exerts its biological effects by selectively binding to the vitamin D receptor (VDR), a nuclear hormone receptor that, upon activation, modulates the transcription of a wide array of genes implicated in the control of cell growth, differentiation, and proliferation. Specifically, calcipotriol may act to possess antiproliferative properties across a diverse range of cancer cell lines, highlighting its potential as useful in oncology research. The interaction between calcipotriol and VDR leads to a downregulation of keratinocyte proliferation—a type of cell involved in the formation of the epidermal layers of the skin—while simultaneously promoting keratinocyte differentiation. This dual action underscores its utility in studies focused on the molecular pathways governing cellular development and the potential disruption of these pathways in disease states.
