StackPR is a new computational approach for large-scale identification of progesterone receptor antagonists using the stacking strategy. Sci Rep 2022; 12:16435. [PMID: 36180453 PMCID: PMC9525257 DOI: 10.1038/s41598-022-20143-5] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2022] [Accepted: 09/09/2022] [Indexed: 11/24/2022] Open
Abstract
Progesterone receptors (PRs) are implicated in various cancers since their presence/absence can determine clinical outcomes. The overstimulation of progesterone can facilitate oncogenesis and thus, its modulation through PR inhibition is urgently needed. To address this issue, a novel stacked ensemble learning approach (termed StackPR) is presented for fast, accurate, and large-scale identification of PR antagonists using only SMILES notation without the need for 3D structural information. We employed six popular machine learning (ML) algorithms (i.e., logistic regression, partial least squares, k-nearest neighbor, support vector machine, extremely randomized trees, and random forest) coupled with twelve conventional molecular descriptors to create 72 baseline models. Then, a genetic algorithm in conjunction with the self-assessment-report approach was utilized to determine m out of the 72 baseline models as means of developing the final meta-predictor using the stacking strategy and tenfold cross-validation test. Experimental results on the independent test dataset show that StackPR achieved impressive predictive performance with an accuracy of 0.966 and Matthew’s coefficient correlation of 0.925. In addition, analysis based on the SHapley Additive exPlanation algorithm and molecular docking indicates that aliphatic hydrocarbons and nitrogen-containing substructures were the most important features for having PR antagonist activity. Finally, we implemented an online webserver using StackPR, which is freely accessible at http://pmlabstack.pythonanywhere.com/StackPR. StackPR is anticipated to be a powerful computational tool for the large-scale identification of unknown PR antagonist candidates for follow-up experimental validation.

Abstract
Steroids are components of cell membranes, signaling molecules and are a type of secondary metabolites as a result of their high impact of biological significance. The present review described the literature reports of pentacyclic steroidal pyrimidines as a type of heterocyclic steroids. The main sections included the synthesis of the investigated steroids fused at rings-A or B or D of steroid skeleton, synthesis of binary or linked-type pyrimidines, pyrimidine oxides, macromolecules and mono- or di- or tri-peptides linked-steroidal pyrimidines. Besides, the present research highlighted the biological significance of steroidal pyrimidines, in which the compounds revealed potent anticancer, antioxidant, antibacterial, and anti-Alzheimer agents. In addition, some hetero-steroids were screened for binding DNA assay and gene expression analysis. It was settled that the incorporation of pyrimidine scaffold into steroid basic skeleton is crucial for better biological results.

Abstract
The reaction of androstenedione with either malononitrile or ethyl cyanoacetate and aromatic aldehydes 2a-c gave the pyran derivatives 4a-f, respectively. On the other hand, the reaction of androstenedione with thiourea and the aromatic aldehydes 2a-c gave the pyrimidine derivatives 6a-c, respectively. Compound 6b reacted with 2-bromo-1-arylethanone derivatives 7a-d to give the indeno[2,1-e]thiazole derivatives 8a-d. Some of the produced compounds were used for further heterocyclization reactions. The cytotoxicity of the newly obtained products was evaluated against some cancer cell lines and a normal cell line.

Synthesis and biological effect of halogen substituted phenyl acetic acid derivatives of progesterone as potent progesterone receptor antagonists. J Steroid Biochem Mol Biol 2008; 111:232-9.

Abstract
In this paper, we report the relative binding affinities to the progesterone receptor (PR) of several progesterone derivatives containing an acetoxyphenyl substituent at C-17 and their structure-bioactivity relationship. The inhibitory effect to ovulation as well as their function as interrupters of endometrial maturation is also described. The biological activity of the novel steroids was determined in vivo and in vitro experiments using female cycling mice, which were synchronized for estrus with luteinizing hormone-releasing hormone (LHRH) and injected with the steroidal compounds. The cytosol used for the determination of the PR, was obtained from the uteri of adult estrogen-primed rabbits and the androgen (AR), mineralocorticoid (MR) and glucocorticoid (GR) receptors were determined in the cytosolic fractions from the prostate of castrated rats and from the kidneys and livers of adenalectomized male rats. We evaluated six related steroidal compounds 8a-8f differing in the nature of the 17alpha ester side chain for the inhibition of [3H] R5020 binding to the PR. The IC50 values for the displacement of [3H] R5020 binding to the PR and its relative binding affinities (RBAs) were determined. Progesterone and R5020 had similar IC(50) values; steroids 8a, 8f and 8c bind to the progesterone receptor with RBAs of 100%, whereas 8e, 8b and 8d have RBA values <100%. These data indicate that there is a relationship between the structure of these steroids and their binding activity to the progesterone receptors. Having demonstrated in this study that steroids 8a-8f bind to the PR, we also evaluated the receptor's selectivity, since some progesterone derivatives bind to AR, MR, GR receptors. We demonstrated that the tested steroids did not bind to the AR, MR, GR, since none of the steroids inhibited the labeled mibolerone, aldosterone or dexamethasone binding to the AR, MR or GR, respectively. These results show that the novel compounds have certain selectivity for the PR. After LHRH treatment, the mice of the control group showed the presence of ova in the oviduct, whereas the animals treated with steroids 8a, 8f, 8e and 8c with RBAs of 92-100%, did not exhibit any ovum in the oviducts. As a result of this study, it is evident that the novel steroids 8a, 8f, 8e and 8c inhibited the ovulation in these animals at dose of 0.22 mg/kg. After the treatment with LHRH, the uterus of the control group showed the typical progestational activity with an enlarged endometrial thickness with secretory activity. However, the endometrium of the mice treated with steroids 8a, 8f, 8e and 8c (with RBAs of 92-100%) neither did show any enlargement of the endometrium, nor a secretory activity could be detected. The diameter of the uterus was also significantly reduced compared to those of the control group, thus indicating that compounds 8a, 8f, 8e and 8c had antagonistic activity in this tissue. The overall data showed that steroids 8a, 8f, 8e and 8c have a high and selective binding activity to the PR. Furthermore there is a relationship between the structure of these steroids and their binding activity, since the presence of fluorine atom in meta position in the acetoxyphenyl substituent at C-17, improved the binding activity as compared to that for the ortho and para positions. These data also demonstrated that 8a-8f have an anti-progestational activity in vivo, and therefore they have better characteristics than the compounds previously reported.

Abstract
A series of novel 11beta-aryl-4',5'-dihydrospiro[estra-4,9-diene-17beta,4'-oxazole] analogs have been evaluated for their antagonist hormonal properties using the T47D cell-based alkaline phosphatase assay and the A549 cell-based functional assay. Some of the compounds showed highly potent, and more selective antiprogestational activity against antiglucocorticoid activity than mifepristone (RU 486).
