The Inhibition of RXRα and RXRβ Receptors Provides Valuable Insights for Potential Prostate Cancer Treatment, in silico Molecular Docking and Molecular Dynamics Studies

Introduction: Prostate cancer has emerged as a widespread health concern, with systemic inflammation believed to substantially contribute to its development and progression. The presence of systemic inflammatory responses has been established as an independent predictor of unfavorable long-term outcomes in prostate cancer patients. The goal of this study is to inhibit RXRα and RXRβ receptors, which are involved in prostate cancer, with Luteolin, Formononetin, and Kaempferol, with varying success. Methods: Retinoid X receptors (RXRs) hold crucial roles within the nuclear receptor (NR) superfamily, and compelling evidence from preclinical studies underscores the therapeutic potential of targeting RXRs for treating neurodegenerative and inflammatory conditions. Consequently, the ability to regulate and modulate RXRs using phytoestrogen ligands, Formononetin, Kaempferol, and Luteolin, assume paramount importance in treatment strategies. Results: The comprehensive in silico findings of this study vividly demonstrate the remarkable efficacy of Luteolin in inhibiting and modulating RXRα and RXRβ, while Formononetin emerges as a notably potent suppressor of RXRβ. Kaempferol, as the third compound, also exhibits commendable inhibitory attributes, although its impact is slightly less pronounced compared to the other two. Discussion: These findings highlight the notable binding and inhibition capabilities to RXRα and RXRβ, offering valuable insights for potential prostate cancer treatment avenues warranting further exploration through in vitro and in vivo analyses.
