Abstract
Dehydroepiandrosterone (3β-hydroxyandrost-5-en-17-one) (DHEA) is a naturally occurring steroid hormone primarily produced in the zona reticularis of the human adrenal glands. It serves as a crucial precursor for sex hormones, such as testosterone, estradiol, and androstenedione. Recent findings indicate that DHEA serves as the primary source of sex steroids in women during both pre- and postmenopausal stages. Additionally, a decline in DHEA levels with age is linked to various hormone-deficiency symptoms. Despite the wide array of biological activities that make DHEA a valuable polycyclic natural steroid, particularly for pharmaceutical and cosmetic applications, reports suggest that oral DHEA has limited clinical effect. Thus, A- and D-ring modified DHEA are synthesized and their biological activities are carried out by different research groups and enhanced biological activity reported in the literature. Here, in this review, we have tried to cover all of the synthetic routes and biological studies of modified A- and D-ring DHEA from 2015 to mid-2022.

Abstract
The development and discovery of steroidal drugs to cure cervical cancer is of the most important. The Claisen condensation of androstene and estrone with aromatic aldehydes was catalyzed by potassium tert. butoxide in tert. butanol to give the corresponding 2-arylidene and 16-arylidene estrone. Subsequently, the 16-arylidene estrone reacted with acid chloride in presence of quaternary amine in halogenated solvent resulting in the steroidal arylidene derivatives. Synthesis, Characterization and in vitro cytotoxic activity of arylidenes are rationalized. Fifteen compounds are synthesized and six of them were evaluated for cytotoxic activity against cervical cancer cell line. HT-3 cell line examination revealed a considerable growth inhibition. Compounds 4a, 4b, 6b, 8c, and 8d, which are estrone-based arylidenes, are the most potent of the series, with IC50 value of 7.15, 10.76, 6.37, 3.56, and 1.55 µM/ml against HT-3 cell line. In addition, molecular docking studies were performed for the steroidal arylidenes to elucidate the binding interactions. Compound 4a, 4b, 6b, 8c and 8d showed excellent binding energy. Docking studies agreed well with in vitro studies. The end result offers an alternative approach to develop steroidal arylidenes that are more effective and are based on estrone, leading to the development of novel anticancer agents.

Synthesis, In Vitro Biological Evaluation of Antiproliferative and Neuroprotective Effects and In Silico Studies of Novel 16E-Arylidene-5α,6α-epoxyepiandrosterone Derivatives. Biomedicines 2023; 11:biomedicines11030812. [PMID: 36979790 PMCID: PMC10045663 DOI: 10.3390/biomedicines11030812] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2023] [Revised: 03/02/2023] [Accepted: 03/04/2023] [Indexed: 03/10/2023] Open
Abstract
Steroids constitute an important class of pharmacologically active molecules, playing key roles in human physiology. Within this group, 16E-arylideneandrostane derivatives have been reported as potent anti-cancer agents for the treatment of leukemia, breast and prostate cancers, and brain tumors. Additionally, 5α,6α-epoxycholesterol is an oxysterol with several biological activities, including regulation of cell proliferation and cholesterol homeostasis. Interestingly, pregnenolone derivatives combining these two modifications were described as potential neuroprotective agents. In this research, novel 16E-arylidene-5α,6α-epoxyepiandrosterone derivatives were synthesized from dehydroepiandrosterone by aldol condensation with different aldehydes followed by a diastereoselective 5α,6α-epoxidation. Their cytotoxicity was evaluated on tumoral and non-tumoral cell lines by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Furthermore, the assessment of the neuroprotective activity of these derivatives was performed in a dopaminergic neuronal cell line (N27), at basal conditions, and in the presence of the neurotoxin 6-hydroxydopamine (6-OHDA). Interestingly, some of these steroids had selective cytotoxic effects in tumoral cell lines, with an IC50 of 3.47 µM for the 2,3-dichlorophenyl derivative in the breast cancer cell line (MCF-7). The effects of this functionalized epoxide on cell proliferation (Ki67 staining), cell necrosis (propidium iodide staining), as well as the analysis of the nuclear area and near neighbor distance in MCF-7 cells, were analyzed. From this set of biological studies, strong evidence of the activation of apoptosis was found. In contrast, no significant neuroprotection against 6-OHDA-induced neurotoxicity was observed for the less cytotoxic steroids in N27 cells. Lastly, molecular docking simulations were achieved to verify the potential affinity of these compounds against important targets of steroidal drugs (androgen receptor, estrogen receptor α, and 5α-reductase type 2, 17α-hydroxylase-17,20-lyase and aromatase enzymes). This in silico study predicted a strong affinity between most novel steroidal derivatives and 5α-reductase and 17α-hydroxylase-17,20-lyase enzymes.

Abstract
The hybrid molecules bearing heterocyclic structures in the A or D rings of steroids have significant biological activity. 16 (E)-Hetereoarylidene steroids were synthesized from the reaction of different heteroaromatic carbaldehydes and trans-Dehydroepiandrosterone (DHEA) in a basic medium. Then, synthesis of the N-formyl pyrazoline substituted new DHEA derivatives were carried out from the reaction of hydrazine hydrate and 16 (E)-hetereoarylidene steroids. The structures of the synthesized compounds were elucidated by elemental analysis, FT-IR, 1H NMR, and 13C NMR spectroscopy. To investigate the activation pathway of synthesized N-formyl pyrazoline substituted steroid derivatives, a molecular docking study was performed on human cytochrome P450-(CYP17A1: PDB ID 5IRQ) with the help of the free AutoDock Vina. 100 ns molecular dynamic simulation process was performed to monitor the behavior of the complex structure formed by CYP17A1 and to calculate the stability over time of 2a and 2d (-9.8 kcal/mol), which gave the lowest value according to the results obtained in the molecular docking study with AutoDock Vina. Accordingly, RMSD, RMSF, Rg, and SASA analyzes of 2a and 2d were performed, and MMPBSA was calculated. Lastly, the ADMET (absorption, distribution, metabolism, excretion, and toxicity) analyses of the novel steroid derivatives were investigated.Communicated by Ramaswamy H. Sarma.

Abstract
Steroids constitute a unique class of chemical compounds, playing an important role in physiopathological processes, and have high pharmacological interest. Additionally, steroids have been associated with a relatively low toxicity and high bioavailability. Nowadays, multiple steroidal derivatives are clinically available for the treatment of numerous diseases. Moreover, different structural modifications on their skeleton have been explored, aiming to develop compounds with new and improved pharmacological properties. Thus, steroidal arylidene derivatives emerged as a relevant example of these modifications. This family of compounds has been mainly described as 17β-hydroxysteroid dehydrogenase type 1 and aromatase inhibitors, as well as neuroprotective and anticancer agents. Besides, due to their straightforward preparation and intrinsic chemical reactivity, steroidal arylidene derivatives are important synthetic intermediates for the preparation of other compounds, particularly bearing heterocyclic systems. In fact, starting from arylidenesteroids, it was possible to develop bioactive steroidal pyrazolines, pyrazoles, pyrimidines, pyridines, spiro-pyrrolidines, amongst others. Most of these products have also been studied as anti-inflammatory and anticancer agents, as well as 5α-reductase and aromatase inhibitors. This work aims to provide a comprehensive overview of steroidal arylidene derivatives described in the literature, highlighting their bioactivities and importance as synthetic intermediates for other pharmacologically active compounds.

Abstract
The neuroprotective effects of some 16-substituted steroidal derivatives against the locomotive impairment and cognitive deficits in the lipopolysaccharide (LPS)-induced neuroinflammation model of rats have been investigated. The in vivo and in vitro evaluations include behavioural tests (actophotometer, block tests, Morris water maize and elevated plus maize), estimation of the biochemical parameters such as acetylcholinesterase, lipid peroxide, reactive oxygen, and nitric oxide species and molecular assays for the key proinflammatory mediators like Tumour Necrosis Factor alpha (TNF-α) and Interleukin 1 beta (IL- 1β) after 21 days of the treatment with the steroids. Behavioural and biochemical studies indicated impairment in the locomotor activity and cognitive dysfunction in rats after LPS treatment. In addition, higher levels of TNF-α and IL-1β in the blood serum of the rats were also noticed. However, significant alleviation of LPS-induced movement and memory disorders was observed in LPS-injected rats after treatment with 16-substituted steroidal derivatives 1-11. Furthermore the biochemical and molecular studies revealed suppression of oxidative and nitrosative stress, decreased acetylcholinesterase activity, and reduction of TNF-α and IL-1β levels after treatment with compounds 1-11. Among all the 16-substituted steroidal derivatives, the compounds 8 and 11 were found to be the most active neuroprotective agents and produced effects marginally better than standard drug dexamethasone.

Abstract
Steroidal pyrazolines constitute an interesting and promising scaffold for drug discovery as they display diverse chemical reactivity and a wide range of biological activities. Literature reports indicate potent anticancer potential of steroidal pyrazolines along with broad-spectrum antimicrobial activities. Strong neuroprotective effects with steroids possessing pyrazoline moiety have also been observed. Among all the therapeutically active steroidal pyrazolines, D-ring-substituted derivatives are highly potent and the least toxic. The current and futuristic research approaches in this area are focused towards the exploration of this promising scaffold to develop molecules with widespread pharmacological activities. This review article mainly covers the synthetic and pharmacological aspects of steroidal pyrazolines, which will assist the medicinal chemists working in this area in their scientific endeavors.

Abstract
The synthesis and neuroprotective efficacy and toxicity studies of a new series of 16,17-N'-(alkyl/arylsulfonyl)pyrazolinyl steroids is presented. Significant suppression of the overexpressed acetylcholinesterase and lipid peroxidation, marked reduction of nitrite, oxidative stress and TNF-α levels and noticeable improvement in cognitive and locomotor functions were observed after treatment with the newly synthesized steroids 2-4a-d in the LPS-treated animal models. Higher neuroprotective effects were produced by some of the pyrazolinyl steroids in comparison to the reference drugs celecoxib and dexamethasone. N'-(4-fluorobenzenesulfonyl) derivative 4c showed the most promising effects on all the analyzed parameters and is the most potent molecule among all compounds of this series. Acute toxicity studies on the most active steroids 2-4c at 50 mg/kg did not reveal any toxic effects on animals, however hepatitis and chronic nephritis were observed in histological examination of liver and kidney of mice after 28 days of treatment. The pyrazolinyl steroids 2-4a-d could be considered as promising candidates for the designing of novel multitarget-directed neuroprotectives for an effective therapy of AD and PD.

Abstract
Alzheimer's disease (AD) and Parkinson's disease (PD) are the most common forms of neurodegenerative disorders. Dehydroepiandrosterone (DHEA) has been reported as a neuroprotective steroid useful in the therapeutic management of neurodegenerative disorders such as AD and PD. Herein we report the synthesis and evaluation of a new series of 16,17-pyrazolinyl DHEA analogues 2-4a-d as neuroprotective agents using LPS-induced neuroinflammation animal models. Treatment with the pyrazoline substituted steroids considerably improved the LPS-induced learning, memory and movement deficits in animal models. Suppression of biochemical parameters of oxidative and nitrosative stress, acetylcholinesterase activity, and TNF-α levels was also observed. 16,17-Pyrazolinyl steroids 2c-4c substituted with a 4-pyridyl moiety at the 5-position of the heterocyclic ring were found to be the most potent agents and produced neuroprotective effects better than standard drugs celecoxib and dexamethasone. Of these pyrazoline substituted steroids, the N-acetyl analogue 3c displayed neuroprotective effects better than N-phenyl (4c), which in turn showed potency more than N-unsubstituted analogue 2c.

Abstract
Rational drug design against a determined target (disease, pathway, or protein) is the main strategy in drug discovery. However, regardless of the main strategy, chemists really wonder how to maximize the utility of their new compounds by drug repositioning them as clinical drug candidates in drug discovery. In this study, we started our drug discovery "from curiosity in the chemical structure of a drug scaffold itself" rather than "for a specific target". As a new drug scaffold, anomeric diarylamino cyclic aminal scaffold 1, was designed by combining two known drug scaffolds (diphenylamine and the most popular cyclic ether, tetrahydropyran/tetrahydrofuran) and synthesized through conventional Brønsted acid catalysis and metal-free α-C(sp3)-H functionalized oxidative cyclization. To identify the utility of the new scaffold 1, it was investigated through 2D and 3D similarity screening and chemocentric target prediction. The predicted proteins were investigated by an experimental assay. The scaffold 1 was reported to have an antineuroinflammatory agent to reduce NO production, and compound 10 concentration-dependently regulated the expression level of IL-6, PGE-2, TNF-α, ER-β, VDR, CTSD, and iNOS, thus exhibiting neuroprotective activity.

Abstract
Peripheral inflammatory responses affect central nervous system (CNS) function, manifesting in symptoms of memory deficits, depression, and anxiety. Previous studies have revealed that neuropeptide VGF (nonacronymic) C-terminal peptide TLQP-62 rapidly reinforces brain-derived neurotrophic factor (BDNF)/tropomyosin receptor kinase B (TrkB) signaling, regulating memory consolidation and antidepressant-like action. However, whether it is beneficial for lipopolysaccharide (LPS)-induced neuropsychiatric dysfunction in mice is unknown. Herein, we explored the involvement of BDNF/TrkB signaling and biochemical alterations in inflammatory or oxidative stress markers in the alleviating effects of TLQP-62 on LPS-induced neuropsychiatric dysfunction. The mice were treated with TLQP-62 (2 μg/side) via intracerebroventricular (i.c.v.) injection 1 h before LPS (0.5 mg/kg, i.p.) administration. Our results showed that a single treatment with LPS (0.5 mg/kg, i.p) is sufficient to produce recognition memory deficits (in the novel object recognition test), depression-like behavior (in the forced swim test and sucrose preference test), and anxiety-like behavior (in the elevated zero maze). However, pretreatment with TLQP-62 prevented LPS-induced behavioral dysfunction, neuroinflammatory, and oxidative responses. In addition, our results further demonstrated that a reduction in BDNF expression mediated by BDNF-shRNA lentivirus significantly blocked the effects of TLQP-62, suggesting the critical role of BDNF/TrkB signaling in the neuroprotective effects of TLQP-62 in the mice. In conclusion, TLQP-62 could be a therapeutic approach for neuropsychiatric disorders, which are closely associated with neuroinflammation and oxidative stress.

Bansal R, Singh R. Exploring the potential of natural and synthetic neuroprotective steroids against neurodegenerative disorders: A literature review. Med Res Rev 2017; 38:1126-1158. [PMID: 28697282 DOI: 10.1002/med.21458] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2017] [Revised: 06/01/2017] [Accepted: 06/20/2017] [Indexed: 12/18/2022]
Abstract
Neurodegeneration is a complex process, which leads to progressive brain damage due to loss of neurons. Despite exhaustive research, the cause of neuronal loss in various degenerative disorders is not entirely understood. Neuroprotective steroids constitute an important line of attack, which could play a major role against the common mechanisms associated with various neurodegenerative disorders like Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis. Natural endogenous steroids induce the neuroprotection by protecting the nerve cells from neuronal injury through multiple mechanisms, therefore the structural modifications of the endogenous steroids could be helpful in the generation of new therapeutically useful neuroprotective agents. The review article will keep the readers apprised of the detailed description of natural as well as synthetic neuroprotective steroids from the medicinal chemistry point of view, which would be helpful in drug discovery efforts aimed toward neurodegenerative diseases.
