Bioactivity | 5,6-trans-Vitamin D3 (5,6-trans-Cholecalciferol;5,6-trans-Colecalciferol) is a photoproduct of vitamin D3[1]. Vitamin D3 is a naturally occuring form of vitamin D. Vitamin D3 induces cell differentiation and prevents proliferation of cancer cells. |
Invitro | Normal human keratinocytes in the cultured human keratinocytes by determining their influence on 3H-thymidine incorporation into DNA.5,6-trans-vitamin D3 only induces significant inhibition at 10(-6) M. The dissociation constants of vitamin D receptor (VDR) for 5,6-trans-vitamin D3 is 560 nM[1]. |
