Abstract
There is compelling evidence that incorporating a heterocyclic moiety into a steroid can alter its pharmacological and pharmacokinetic properties, driving intense interest in the synthesis of such hybrids among research groups. In this review, we present an overview of recent synthetic methodologies, spanning the period from 2000 to 2023, for the preparation of spiro heterocyclic steroids. The compounds surveyed encompass four-, five-, six-, and seven-membered heterocycles appended to various positions of steroidal backbones, with spirocycles containing oxygen, nitrogen, and sulfur atoms being predominant. The outlined synthetic procedures emphasize the pivotal steps for constructing the heterocycles, often accompanied by a detailed account of the overall synthesis pathway. The review encompasses innovative compounds, including bis-steroids linked by a spiro heterocycle and steroids conjugated to heterocyclic moieties containing three or more (hetero)cycles. Moreover, many compounds are accompanied by data on their biological activities, such as antiproliferative, antimalarial, antimicrobial, antifungal, steroid antagonist, and enzyme inhibition, among others, aimed at furnishing pertinent insights for the future design of more potent and selective drugs.

Abstract
The synthesis and NMR structure analysis of a group of oxygenated steroids containing isoxazole, dihydrofuran, tetrahydrofuran rings or enamino carbonyl fragment in the side chain have been fulfilled. The prepared compounds were tested toward several enzymes (human cytochrome P450s CYP17, CYP19, CYP51 and CYP51 of pathogenic fungus Candida glabrata) as their potential inhibitors. A number steroids show a high level affinity (micro- and submicromole) for the enzyme-ligand complexes of the tested compounds with human CYP51, CYP19 and CYP51 of C. glabrata.

Synthesis and characterization of β-cyclodextrin-conjugated alginate hydrogel for controlled release of hydrocortisone acetate in response to mechanical stimulation. J BIOACT COMPAT POL 2015.

Abstract
Alginate hydrogels are a class of biomaterials that can be used as local release depots for therapeutic agents. A particular drug that can take advantage of alginate hydrogel for controlled release is hydrocortisone acetate. Hydrocortisone acetate is a widely used anti-inflammatory agent, but is limited in application due to poor solubility and lack of controlled delivery. To overcome this limitation, a mechanically responsive β-cyclodextrin-conjugated alginate (Alg-β-CD) hydrogel was synthesized and characterized for enhanced aqueous solubility and controlled release of hydrocortisone acetate. We demonstrated that mono-6-deoxy-6-ethylenediamine-β-cyclodextrin and hydrocortisone acetate formed a 1:1 inclusion complex, thus resulting in marked increase in hydrocortisone acetate solubility, while causing no significant inhibition to the growth of cultured mouse fibroblasts (L929). More importantly, the release of hydrocortisone acetate from the hydrogel system was increasingly sensitive to mechanical compression, and the mechanical responsiveness of hydrocortisone acetate release increased dramatically as the concentration of mono-6-deoxy-6-ethylenediamine-β-cyclodextrin increased from 0% to 46%, whereas the swelling rate and stiffness of the hydrogel decreased as the concentration of mono-6-deoxy-6-ethylenediamine-β-cyclodextrin increased. The mechanical responsiveness of hydrocortisone acetate release was attributable to conformational distortion of mono-6-deoxy-6-ethylenediamine-β-cyclodextrin moieties and deformation of the polymer network. Moreover, we demonstrated that the hydrogel continuously released and accumulated hydrocortisone acetate in the medium when compressed for up to 72 h, which led to increasing suppression of nitric oxide production in the lipopolysaccharide-stimulated mouse macrophages (RAW264.7), indicating desirable anti-inflammatory effect at the cell level. Hence, this hydrogel system may provide a useful platform for drug delivery, such as hydrocortisone acetate release to wound site, by intentionally generated mechanical force.

Abstract
Mometasone furoate (MF) is a topical glucocorticoid used for atopic dermatitis, allergic rhinitis, and bronchial asthma. To elucidate the usefulness of MF, the dissociation between local anti-inflammatory effects and systemic effects of MF was compared with that of beclomethasone 17,21-dipropionate (BDP). MF was more potent than BDP in croton oil-induced ear edema tests in mice. Oral systemic effects of MF were inversely lower than that of BDP on thymolysis, plasma corticosterone lowering, and suppression of body weight gain in mice. These results indicate that MF has a higher therapeutic index and superior clinical usefulness as a topical glucocorticoid compared to BDP.

Abstract
The prodrug and antedrug concepts, which were developed to overcome the physical and pharmacological shortcomings of various therapeutic classes of agents, employ diametrically different metabolic transformations. The prodrug undergoes a predictable metabolic activation prior to exhibiting its pharmacological effects in a target tissue while the antedrug undergoes metabolic deactivation in the systemic circulation upon leaving a target tissue. An increased therapeutic index is the aspiration for both approaches in designing as well as evaluation criteria. The recent research endeavors of prodrugs include the gene-directed and antibody-directed enzymatic activation of a molecule in a targeted tissue, organ specific delivery, improved bioavailabilities of nucleosides and cellular penetration of nucleotides. As for antedrugs, emphasis in research has been based upon the design and synthesis of systemically inactive molecule by incorporating a metabolically labile functional group into an active molecule.

Abstract
In an effort to determine the C-20 chirality effect on the antiinflammatory activity of 17beta-glycolate esters, methyl 11beta,17alpha,20-trihydroxy-3-oxo-1,4-pregnadien-21-oate and its 9alpha-fluoro analog, their acetonide and their carbonate derivatives were synthesized and evaluated. The agents were tested for their binding potency to the macrophage glucocorticoid receptor, and their effect on LPS-induced nitric oxide generation in RAW 264.7 cells. The acetonide derivatives showed the highest binding affinity while the triols and carbonates bound rather poorly to the receptors. With the exception of the triols, the alpha-isomer in each pair of the agents exhibited higher binding affinity to the receptor than its corresponding beta-isomer, clearly indicating that C-20 chirality has a significant effect on antiinflammatory activity. In addition, the alpha-isomers of the acetonides showed substantially higher binding affinity than the parent compound, prednisolone. In contrast to the high binding activity exhibited by some of the acetonides, all of the agents showed weak inhibitory effect on NO generation. Metabolic inactivation during assessment of NO inhibition may play a role in the divergence noted between receptor affinity and the measured biologic activity resulting from the binding.
