Abstract
Current efforts in the vitamin D field are directed toward the development of highly antiproliferative yet noncalcemic analogues of the natural hormone 1α,25-dihydroxyvitamin D3 (1,25D3). We have recently reported the design, synthesis, biological evaluation, and crystal structures of a series of novel analogues that both lack the steroidal C-ring and have an m-phenylene ring replacing the steroidal cyclopentane D-ring. We have now investigated the potentiating effects of incorporating selected modifications (hexafluorination and/or an internal triple bond) within the steroidal side chain in our series. An alternative synthetic strategy (Wittig-Horner approach instead of our previously used Pd-catalyzed tandem cyclization/cross-coupling) for the construction of the vitamin D triene system was found convenient for the target compounds 2, 3a, 3b, and 3c of this report. These modifications enhance vitamin D nuclear receptor (VDR) interactions and consequently VDR-associated biological properties compared to parental PG-136 compound while maintaining normal calcium levels.

Nutrients 2023; 15:4697.

Abstract
Vitiligo is a common autoimmune skin disease caused by autoreactive CD8+ T cells. The diverse effects of 1,25-dihydroxyvitamin D₃ [1,25(OH)₂D₃] on immune cell metabolism and proliferation have made it an interesting candidate as a supporting therapeutic option in various autoimmune diseases. This study aimed to elucidate the immunomodulatory effects of 1,25(OH)₂D₃ in vitiligo. Cross-sectional relationships between serum 1,25(OH)₂D₃ levels and disease characteristics were investigated in 327 patients with vitiligo. The immunomodulatory and therapeutic effects of 1,25(OH)₂D₃ were then investigated in vivo and in vitro, respectively. We found that 1,25(OH)₂D₃ deficiency was associated with hyperactivity of CD8+ T cells in the vitiligo cohort. In addition, 1,25(OH)₂D₃ suppressed glycolysis by activating the AMP-activated protein kinase (AMPK) signaling pathway, thereby inhibiting the proliferation, cytotoxicity and aberrant activation of CD8+ T cells. Finally, the in vivo administration of 1,25(OH)₂D₃ to melanocyte-associated vitiligo (MAV) mice reduced the infiltration and function of CD8+ T cells and promoted repigmentation. In conclusion, 1,25(OH)₂D₃ may serve as an essential biomarker of the progression and severity of vitiligo. The modulation of autoreactive CD8+ T cell function and glycolysis by 1,25(OH)₂D₃ may be a novel approach for treating vitiligo.

Abstract
The toxic calcemic effects of the natural hormone 1α,25-dihydroxyvitamin D3 (1,25D3, 1,25-dihydroxycholecalciferol) in the treatment of hyperproliferative diseases demand the development of highly active and noncalcemic vitamin D analogues. We report the development of two highly active and noncalcemic analogues of 1,25D3 that lack the C-ring and possess an m-phenylene ring that replaces the natural D-ring. The new analogues (3a, 3b) are characterized by an additional six-carbon hydroxylated side chain attached either to the aromatic nucleus or to the triene system. Both compounds were synthesized by the Pd-catalyzed tandem cyclization/cross coupling approach starting from alkyne 6 and diphenol 8. Key steps include a stereoselective Cu-assisted addition of a Grignard reagent to an aromatic alkyne and a Takai olefination of an aromatic aldehyde. The new compounds are noncalcemic and show transcriptional and antiproliferative activities similar to 1,25D3. Structural analysis revealed that they induce a large conformational rearrangement of the vitamin D receptor around helix 6.

Abstract
The active form of vitamin D3 (D3), 1a,25-dihydroxyvitamn D3 (1,25D3), plays a central role in calcium and bone metabolism. Many structure–activity relationship (SAR) studies of D3 have been conducted, with the aim of separating the biological activities of 1,25D3 or reducing its side effects, such as hypercalcemia, and SAR studies have shown that the hypercalcemic activity of C2-substituted derivatives and 19-nor type derivatives is significantly suppressed. In the present paper, we describe the synthesis of 19-nor type 1,25D3 derivatives with alkoxy groups at C2, by means of the Julia–Kocienski type coupling reaction between a C2 symmetrical A ring ketone and a CD ring synthon. The effect of C2 substituents on the stereoselectivity of the coupling reaction was evaluated. The biological activities of the synthesized derivatives were evaluated in an HL-60 cell-based assay. The a-methoxy-substituted C2α-7a was found to show potent cell-differentiating activity, with an ED50 value of 0.38 nM, being 26-fold more potent than 1,25D3.

Abstract
A new series of highly biologically active (20S,22R)-1α,25-dihydroxy-22-methyl-2-methylene-vitamin D3 analogs, possessing different side chains, have been efficiently prepared as potential agents for medical therapy. Design of these synthetic targets was based on the analysis of the literature data and molecular docking experiments. The synthetic strategy involved Sonogashira coupling of the known A-ring dienyne with the C,D-ring enol triflates, obtained from the corresponding Grundmann ketones. All synthesized vitamin D compounds were characterized by high in vitro potency and, moreover, they proved to be very calcemic in vivo exerting high activity on bone with particularly elevated intestinal calcium transport.

Abstract
The hypercalcemic effects of the hormone 1α,25-dihydroxyvitamin D3 (calcitriol) and most of known vitamin D metabolites and analogs call for the development of non secosteroidal vitamin D receptor (VDR) ligands as new selective and noncalcemic agonists for treatment of hyperproliferative diseases. We report on the in silico design and stereoselective synthesis of six lithocholic acid derivatives as well as on the calcemic activity of a potent LCA derivative and its crystallographic structure in complex with zVDR LBD. The low calcemic activity of this compound in comparison with the native hormone makes it of potential therapeutic value. Structure-function relationships provide the basis for the development of even more potent and selective lithocholic acid-based VDR ligands.

Abstract
1α,25-Dihydroxyvitamin D3 [1α,25-(OH)2-D3], the hormonally active form of vitamin D3, classically regulates bone formation, calcium, and phosphate homeostasis. In addition, this hormone also exerts non-classical effects in a wide variety of target tissues and cell types, such as inhibition of the proliferation and stimulation of the differentiation of normal and malignant cells. However, to produce these actions, supraphysiological doses are required resulting in calcemic effects that limit the use of this natural hormone. During the past 30 years, many structurally modified analogs of the 1α,25-(OH)2-D3 have been synthesized in order to find derivatives that can dissociate the beneficial antiproliferative effects from undesired calcemic effects. Among these candidates, 1α,25-(OH)2-19-nor-D3 analogs have shown promise as good derivatives since they show equal or better activity relative to the parent hormone but with reduced calcemic effects. In this review, we describe the synthetic strategies to obtain the 19-nor-D3 derivatives and briefly describe their physiological activities.

Abstract
![]()
For many individuals,
in particular during winter, supplementation
with the secosteroid vitamin D3 is essential for the prevention
of bone disorders, muscle weakness, autoimmune diseases, and possibly
also different types of cancer. Vitamin D3 acts via its
metabolite 1α,25-dihydroxyvitamin D3 [1,25(OH)2D3]
as potent agonist of the transcription factor vitamin D receptor (VDR).
Thus, vitamin D directly affects chromatin structure and gene regulation
at thousands of genomic loci, i.e., the epigenome and transcriptome
of its target tissues. Modifications of 1,25(OH)2D3 at its
side-chain, A-ring, triene system, or C-ring, alone and in combination,
as well as nonsteroidal mimics provided numerous potent VDR agonists
and some antagonists. The nearly 150 crystal structures of VDR’s
ligand-binding domain with various vitamin D compounds allow a detailed
molecular understanding of their action. This review discusses the
most important vitamin D analogs presented during the past 10 years
and molecular insight derived from new structural information on the
VDR protein.

Abstract
Herein, we describe our studies on the synthesis of 1α,25-dihydroxyvitamin D3 analogs possessing a benzene ring replacing the natural 5-membered D-ring by the Wittig-Horner and dienyne approaches. A key feature is the synthesis of a Cr(CO)3-complexed previtamin D derivative that enables the construction of vitamin D analogs with aromatic D-ring through a thermal [1,7]-H sigmatropic shift. This study establishes the basis for the design of new vitamin D analogs containing aromatic D-ring, complexed or uncomplexed to Cr(CO)3 type moieties for specific molecular recognition and drug research and development.

Abstract
Pronounced biological potency of 19-norvitamin D compounds as well as interesting biological action of the vitamin D analogs possessing elongated side chains encouraged us to expand the scope of our structure-activity studies to encompass such modifications of the 1α,25-(OH)2D3 (calcitriol) molecule. The aim of our studies was the synthesis of calcitriol analog, designed on the basis of results of molecular modeling and docking experiments, and characterized by a presence of a long, nitrogen-containing substituent attached to carbon 26, and an exomethylene moiety transferred from C-10 to C-2. The convergent synthesis of such 19-norcalcitriol compound, described in this communication, consisted of the preparation and combining four building blocks. The crucial point of the synthesis, coupling of the known A-ring phosphine oxide and the synthesized Grundmann ketone analog, was achieved using Wittig-Horner protocol. It provided the protected analog of 1α,25-dihydroxy-2-methylene-19-norvitamin D3 which was further transformed into the target compound.

Abstract
Various 19-nor vitamin D analogs, which lack the methylene group at C19, exhibit significant vitamin D (VD)-related biological activities, but generally show a reduced calcemic side-effect compared with VD itself. Among them, paricalcitol is already used clinically for treatment and prevention of secondary hyperparathyroidism associated with chronic renal failure. Therefore, considerable synthetic efforts have been directed towards 19-nor VD analogs, focusing especially on A-ring synthons suitable for use in convergent synthetic strategies based on coupling of CD-ring synthons and A-ring synthons. For example, we have recently developed a new synthetic route to A-ring synthons from linear dienes based upon a ring-closing olefin metathesis strategy. Here, we review recent synthetic approaches to A-ring synthons for 19-nor VD derivatives.

Abstract
Prompted by results of molecular modeling performed on the seco-d-ring-vitamins D, we turned our attention to such analogs, having reversed configurations at C-13 and C-14, as the next goals of our studies on the structure-activity relationship for vitamin D compounds. First, we developed an efficient total synthesis of the "upper" C/seco-d-ring fragment with a 7-carbon side chain. Then, we coupled it with A-ring fragments using Sonogashira or Wittig-Horner protocol, providing the targeted D-seco analogs of 1α,25-dihydroxyvitamin D3 and 1α,25-dihydroxy-19-norvitamin D3 possessing a vinyl substituent at C-14 and a double bond between C-17 and C-20. The affinities of the synthesized vitamin D analogs to the full-length recombinant rat VDR were examined, as well as their differentiating and transcriptional activities. In these in vitro tests, they were significantly less active compared to 1α,25-(OH)2D3. Moreover, it was established that the analogs tested in vivo in rats showed no calcemic potency.

Abstract
As a continuation of our efforts directed to the structure-activity relationship studies of vitamin D compounds, we present in this paper the synthesis of new analogues of 1α,25-(OH)2D3 characterized by numerous structural modifications, especially a cleaved D ring. Total synthesis of the CD fragment required for the construction of the target vitamins was based on the Stork approach. The structure of the key intermediate - bicyclic hydroxy lactone - was established by crystallographic and electronic circular dichroism (ECD) spectral analysis. Following the attachment of the hydroxyalkyl side chain, the formed D-seco Grundmann ketone was subjected to Wittig-Horner coupling with the corresponding A-ring phosphine oxides providing two desired D-seco analogues of 19-nor-1α,25-(OH)2D3, one without a substituent at C-2 and the other possessing a 2-exomethylene group. Both compounds were biologically tested and the latter was found to be more active in in vitro tests. Despite so many structural changes introduced in its structure, the biological activity of the 2-methylene analogue approached that of the natural hormone. The synthesized D-seco vitamins, however, proved to be inactive on bone and intestine in vivo.

Abstract
INTRODUCTION Vitamin D3 activates via its hormonal form 1α,25-dihydroxyvitamin D3 (1α,25(OH)2D3), the transcription factor vitamin D receptor (VDR). VDR is expressed in most human tissues and has more than 1,000 target genes. Thus, 1α,25(OH)2D3 and its synthetic analogs have a broad physiological impact. The crystal structures of the VDR ligand-binding domain (LBD), and its various ligands, allows further the understanding of the receptor's molecular actions. Areas covered: We discuss the most important novel VDR ligands and the further insight derived from new structural information on VDR. Expert opinion: There is an increasing appreciation of the impact of vitamin D and its receptor VDR not only in bone biology, but also for metabolic diseases, immunological disorders, and cancer. Detailed structural analysis of the interaction of additional novel ligands with VDR highlight helices 6 and 7 of the LBD as being most critical for stabilizing the receptor for an efficient interaction with co-activator proteins, i.e. for efficient agonistic action. This permits the design of even more effective VDR agonists. In addition, chemists took more liberty in replacing major parts of the 1α,25(OH)2D3 molecule, such as the A- and CD-rings or the side chain, with significantly different structures, such as carboranes, and still obtained functional VDR agonists.

Abstract
In an attempt to prepare vitamin D analogues that are superagonists, (20R)- and (20S)-isomers of 1α-hydroxy-2-methylenevitamin D3 and 1α,25-dihydroxy-2-methylenevitamin D3 have been synthesized. To prepare the desired A-ring dienyne fragment, two different approaches were used, both starting from the (-)-quinic acid. The obtained derivative was subsequently coupled with the C,D-ring enol triflates derived from the corresponding Grundmann ketones, using the Sonogashira reaction. Moreover, (20R)- and (20S)-1α,25-dihydroxy-2-methylenevitamin D3 compounds with an (5E)-configuration were prepared by iodine catalyzed isomerization. All four 2-methylene analogues of the native hormone were characterized by high in vitro activity. As expected, the 25-desoxy analogues were much less potent. Among the synthesized compounds, two of them, 1α,25-dihydroxy-2-methylenevitamin D3 and its C-20 epimer, were found to be almost as active as 2-methylene-19-nor-(20S)-1α,25-dihydroxyvitamin D3 (2MD) on bone but more active in intestine.

Abstract
The steroid hormone 1α,25-dihydroxyvitamin D3 [1α,25-(OH)2D3] is the most active metabolite of vitamin D3 which exerts its control over a multitude of biological processes related to calcium and phosphorus homeostasis, cell proliferation and differentiation, and immune regulation. Unfortunately, the therapeutic application of 1α,25-(OH)2D3 is limited by induction of hypercalcemia. The need for vitamin D compounds with selective biological profiles has stimulated the synthesis of more than three thousand analogs of 1α,25-(OH)2D3. Most of these compounds have structural modifications in the side chain and A-ring; there is also an increasing number of modifications in the CD-rings and limited number in the triene system (seco-B ring). Herein, we report the synthesis and biological evaluation of seco-A-19-nor analogs of 1α,25-dihydroxyvitamin D3, developed to study the role of ring A in the biological activity of 1α,25-(OH)2D3. Interestingly, compounds 2 and 4 show substantial ability to bind the vitamin D receptor and the former is also characterized by selective intestinal calcium transport activity. This article is part of a Special Issue entitled 'Vitamin D Workshop'.
