(R)-Vitamin D2 is an isomer of Vitamin D2, and it can serve as a control compound in experiments. Vitamin D2 (Ergocalciferol) is sourced from food or dietary supplements and is used as a supplement for Vitamin D.

Biotin (S)-sulfoxide is an inactive metabolite of the coenzyme biotin .1,2It has also been found inE. coliand is reduced by the biotin sulfoxide reduction system as a source of biotin.3 1.Denkel, L.A., Rhen, M., and Bange, F.-C.Biotin sulfoxide reductase contributes to oxidative stress tolerance and virulence in Salmonella enterica serovar TyphimuriumMicrobiology (Reading)159(Pt 7)1447-1458(2013) 2.Carling, R.S., and Turner, C.Methods for assessment of biotin (Vitamin B7)Laboratory assessment of vitamin status193-217(2019) 3.del Campillo-Campbell, A., Dykhuizen, D., and Clearly, P.P.Enzymic reduction of d-biotin d-sulfoxide to d-biotinMethods Enzymol.62379-385(1979)

2-O-β-D-Glucopyranosyl-L-ascorbic acid (AA-2βG) is a natural and stable vitamin C analog that induces apoptosis and cell cycle arrest in cancer cells by stabilizing p53 protein.

VDR agonist 1 (compound 28), a nonsteroidal Vitamin D receptor (VDR) agonist, demonstrates potent activity with a low IC 50 of 690 nM in MCF-7 cells. It inhibits cell cycle progression through upregulation of p21 and p27, and induces apoptosis by elevating BAX expression while reducing Bcl-2 levels [1].

3-O-(2-Aminoethyl)-25-hydroxyvitamin D3 is a derivative of Vitamin D3.

Tributyrin (Glyceryl tributyrate), a neutral short-chain fatty acid triglyceride, is a stable and rapidly absorbed prodrug of Butyric Acid. It diffuses through biological membranes and is metabolized by intracellular lipases, releasing effective butyrate directly into cells in vivo, exhibiting potent proapoptotic, antiproliferative, and differentiation-inducing effects.

Osteocalcin (1-49) is a non-collagenous peptide that is secreted by osteoblasts and odontoblasts and comprises 1-2% of the total protein in bone. Secretion of osteocalcin (1-49) is stimulated by 1,25-dihydroxy vitamin D and plasma levels increase in diseases that induce dysregulated bone turnover such as osteoporosis, Paget's disease, and primary hyperparathyroidism. Osteocalcin (1-49) is positively correlated with insulin sensitivity and negatively correlated with high blood glucose levels in women. In vitro, osteocalcin induces chemotaxis of MDA-MB-231 breast cancer cells, human peripheral blood monocytes, and rat osteosarcoma cells with osteoblast-like characteristics. It is also expressed by vascular smooth muscle cells (VSMCs) displaying an osteoblast-like phenotype and has been positively associated with calcification of aortic tissue and heart valves in humans.

TEI-9648, an analogue of Vitamin D3 Lactone, acts as a potent and specific antagonist to the vitamin D receptor (VDR). This compound effectively blocks the genomic actions mediated by VDR and the Vitamin D responsive element (VDRE) of 1α,25(OH)2D3. Furthermore, TEI-9648 prevents the differentiation of HL-60 cells induced by 1α,25(OH)2D3, indicating its utility in bone metabolism studies[1][2].

2MD, an orally active vitamin D analog, both stimulates periosteal bone formation and decreases trabecular bone resorption, effectively restoring trabecular and cortical bone mass and strength. Additionally, 2MD regulates genes related to intraocular pressure (IOP) and reduces IOP in non-human primates [1] [2].

VDR agonist 2 (compound 16i), a vitamin D receptor (VDR) agonist, effectively inhibits TGF-β1-induced hepatic stellate cell (HSC) activation, demonstrating notable anti-hepatic fibrosis efficacy both in vitro and in vivo [1].

Vitamin B15 (Pangamic Acid) hemicalcium, a substance naturally ubiquitous in plant seeds, serves as a stimulant for cellular respiration and contains D-gluconodimethyl amino acetic acid. This compound also acts as an immune-correcting agent [1] [2] and is applicable in treating a wide range of diseases.
