Sesquiterpenoids from myrrh inhibit androgen receptor expression and function in human prostate cancer cells

Aim:

To examine whether two naturally occurring sesquiterpenoids (ST1 and ST2) with anti-proliferative activity in prostate cancer cells inhibit androgen receptor (AR) signaling.

Methods:

Human prostate cancer cell lines LNCaP and PC3 were used. The expression of AR, AR translocation into the nucleus, and expression levels of AR coactivators ARA70 and steroid receptor coactivator-1 (SRC-1) in LNCaP cells were examined using real-time PCR and Western blot. Changes in prostate-specific antigen (PSA) protein levels, PSA promoter activity, and androgen response element (ARE)-mediated reporter gene activity were examined using enzyme-linked immunoabsorbent assay (ELISA) and transient transfection assays. Co-immunoprecipitation was performed to analyze the interaction between AR and the AR coactivators in ST1- and ST2-treated cells.

Results:

In LNCaP cells, ST1 and ST2 (40 μmol/L) led to a significant decrease in the expression of AR as well as a reduction of AR translocation into the nucleus, but had no effect on AR protein translation. ST1 and ST2 treatment also resulted in a significant decrease in the level of PSA protein secreted into the medium and was able to suppress PSA promoter-dependent and ARE-dependent luciferase activity. Furthermore, decreased expression of ARA70 and SRC-1 was observed when LNCaP cells were exposed to ST1 and ST2, which interfered with their ability to interact with AR.

Conclusion:

The observations suggest that suppression of AR transactivation by ST1 and ST2 may be mediated, in part, by inhibiting AR nuclear translocation and/or interfering with the interaction between AR and its coactivators ARA70 and SRC-1. Therefore, sesquiterpenoids could be developed as novel therapeutic agents for treating prostate cancer.

Single-step green synthesis of gold conjugated polyphenol nanoparticle using extracts of Saudi’s myrrh: Their characterization,molecular docking and essential biological applications

The progress in the innovative nanocrystal synthesis process by using environmentally benign and low-priced nontoxic chemicals, solvents, and renewable sources remains a challenging task for researchers worldwide. The majority of the existing synthesis techniques engage in the potentially dangerous, for either human health or the environment. Current investigation has been centered on green synthesis processes to create novel nanomaterials, which are eco-friendly as well as safer for sustainable marketable feasibility. The current work provides the green synthesis method for gold nanoparticle (GNPs) synthesis using Commiphora myrrh (C.myrrh) extract. This simple method includes 6 ml of HAuCl₄·3H₂O treated with 4 ml C.myrrh extract having pH 4.5 after 80 min at 25 °C temperature. In this novel method, green synthesized GNPs characterized by UV–Vis, X^_ray diffraction spectroscopy (XRD), zeta potential, fourier transform infrared (FT^_IR), high^_resolution transmission electron microscopy (HR^_TEM), energy dispersive X^_ray spectroscopy (EDXA), and dynamic light scattering (DLS). During the development successful antioxidant assay, the DPPH assay was applied. The cell toxicity of green synthesized GNPs was evaluated following an MTT assay against HCT-116 (colon cancer) and MCF-7 (breast cancer).Besides molecular docking in the δ-elemene for inhibitor to VEGFR‐2 domain revealed more negative docking score (−3.976) which is an excellent binding affinity to the C.myrrh@GNP. The synthesized GNPs showed antidiabetic, antibiotic, and antibacterial properties and anti^_inflammatory inhibition against inhibiting COX-1, and COX-2 enzymes. In addition, molecular docking by Lindestrene (−3.806) and Furanoeudesma-1,3-dien (−3.912) against COX1 and COX2 respectively showed strong binding affinity. The molecular docking study evidenced the anti-inflammatory and cell toxicity study.

Bactericidal effect of the sesquiterpene T-cadinol on Staphylococcus aureus

The antimicrobial effects of the sesquiterpene T-cadinol, isolated from the Somalian traditional remedy, scented myrrh (resin of Commiphora guidottii Chiov., Burseraceae), were investigated. The compound was found to be active toward Staphylococcus aureus and Trichophyton mentagrophytes. The minimum inhibitory concentration of T-cadinol on S. aureus was 24 μg/mL and the lowest concentration exerting fungicidal effect on T. mentagrophytes was 2.3 μg/mL. The influence of T-cadinol cell viability in S. aureus, both in different growth-phases, and in the absence and presence of chloramphenicol, was studied. It could be concluded that T-cadinol has a bactericidal rather than a bacteriostatic effect, which acts also in the absence of growth. Furthermore, the effect of T-cadinol on S. aureus was analysed and documented with transmission electron microscopy. The electron micrographs clearly showed that T-cadinol interacted with the cell envelopes, causing bacterial lysis and subsequent fatal loss of intracellular material. The effect of the substance was thus characterized as bacteriolytic. The use of scented myrrh in traditional medicine as a remedy for wounds may then be in congruence with this bactericidal effect of T-cadinol toward the common wound pathogen S. aureus.
