Calcifediol is a major circulating metabolite of vitamin D3 and acts as a competitive inhibitor with an apparent Ki of 3.9 μM. It also suppresses PTH secretion and mRNA (ED50=2 nM).
(E) Qualitative representations of zebrafish larvae, showing ISV to be unchanged or slightly reduced in response to 20 μM seocalcitol, maxacalcitol, calcitriol, calcifediol and tacalcitol treatment between 6 hpf and 2 dpf. Scale bar represents 200 μm. (F) Qualitative representation of intact ISV after 10 μM seocalcitol, maxacalcitol, calcitriol, calcifediol and tacalcitol treatment from 2-5 dpf. Scale bar represents 200 μm.
Alfacalcidol is a non-selective VDR activator medication.
Vitamin D analogs induce adenylate kinase release from S. mutans planktonic cells. S. mutans UA159 cultures were grown in TY medium + 1% (w/v) glucose to exponential phase and used to inoculate fresh medium containing ciprofloxacin (positive control), DMSO (negative control), alfacalcidol, calcitriol, or doxercalciferol at 16, 32, and 64 μg/mL for 4h. Cell lysis was detected using the AK assay as described in Materials and Methods. Data is represented as relative luminescence units (RLU) normalized to background (DMSO) and is representative of three replicate cultures performed in triplicate. (* p<0.05; Student’s t-Test; two-tailed).
